The use of this data enables the efficient management of urban resources, assets, and services. Information systems, waste management, crime detection, power plants, municipal facilities, water supply networks, transportation systems, schools, libraries, hospitals, and other social services are just a few of the places where data from citizens, devices, and urban resources are gathered, processed, and analyzed (<a class="elsevierStyleCrossRef" href="#bib0003">Ajaj, Buniya, Wuni & Yousif, 2024</a>; <a class="elsevierStyleCrossRef" href="#bib0030">Lin et al., 2021</a>). To improve service delivery, streamline urban processes, and engage effectively with residents, a smart city aims to integrate information and communication technology (ICT) with a variety of physical devices that are linked to the Internet of Things (IoT) (<a class="elsevierStyleCrossRef" href="#bib0014">Del-Real, Ward & Sartipi, 2023</a>; <a class="elsevierStyleCrossRef" href="#bib0019">Khan, Siddiqui, Rahmani & Husain, 2022</a>). City officials can respond quickly to the needs of the city and its residents by interacting directly with the community and urban infrastructure thanks to smart city technology (<a class="elsevierStyleCrossRef" href="#bib0017">Janurova et al., 2020</a>).</p><p id="para0002" class="elsevierStylePara elsevierViewall">A sustainable smart city is composed of various components that together create a coordinated and effective combination to improve the quality of life for citizens. One of the essential components of sustainable smart cities is the use of big data. Big data refers to large volumes of data collected from various sources (<a class="elsevierStyleCrossRef" href="#bib0003">Ajaj et al., 2024</a>; <a class="elsevierStyleCrossRef" href="#bib0023">Khazaei, Zareian, Veleda & Litoiu, 2016</a>). This data can come from sources such as sensors, social networks, public transportation systems, and more. The importance of big data in smart cities lies in its ability to extract usable information and valuable patterns for urban management through the analysis of large datasets. This data helps city officials make better decisions regarding traffic management, energy consumption optimization, forecasting citizen needs, and improving urban services. In other words, big data aids smart cities in enhancing decision-making and providing urban services (<a class="elsevierStyleCrossRef" href="#bib0007">Barham & Daim, 2018</a>; <a class="elsevierStyleCrossRef" href="#bib0016">Hashem et al., 2016</a>; <a class="elsevierStyleCrossRef" href="#bib0030">Lin et al., 2021</a>).</p><p id="para0003" class="elsevierStylePara elsevierViewall">Big data is a powerful tool in a smart city that can significantly improve urban management and service delivery. Applications of big data in a smart city include traffic prediction, energy management improvement, better urban service delivery, and improved crisis management. Although big data plays a crucial role in transforming cities into smart cities, its implementation faces several challenges (<a class="elsevierStyleCrossRef" href="#bib0017">Janurova et al., 2020</a>; <a class="elsevierStyleCrossRef" href="#bib0030">Lin et al., 2021</a>). One of the primary obstacles to implementing big data in smart cities is the issue of data privacy and security. The collection and use of sensitive data can lead to fears and security concerns among citizens. Additionally, technical issues related to processing and storing large volumes of data can pose barriers to the successful implementation of big data in smart cities. To address these challenges, common policies and standards regarding privacy, data security, and large-scale data management are needed (<a class="elsevierStyleCrossRef" href="#bib0003">Ajaj et al., 2024</a>; <a class="elsevierStyleCrossRef" href="#bib0016">Hashem et al., 2016</a>; <a class="elsevierStyleCrossRef" href="#bib0019">Khan et al., 2022</a>; <a class="elsevierStyleCrossRef" href="#bib0023">Khazaei et al., 2016</a>; <a class="elsevierStyleCrossRef" href="#bib0036">Mutambik, 2024</a>).</p><p id="para0004" class="elsevierStylePara elsevierViewall">Numerous studies have investigated the use of big data in smart cities and the challenges and risks associated with it. For example, <a class="elsevierStyleCrossRef" href="#bib49">Villegas-Ch et al. (2019)</a> highlighted that the need for substantial investments in socio-economic and technical resources creates barriers to big data implementation in smart cities. <a class="elsevierStyleCrossRef" href="#bib50">Rathore et al. (2018)</a> pointed out the difficulties in integrating IoT devices and smart systems to efficiently gather and process vast amounts of urban data in real time. <a class="elsevierStyleCrossRef" href="#bib0020">Khan (2021)</a> identified data complexity, the framework for big data adoption, and the lack of necessary technologies as major obstacles to incorporating big data analytics in smart city development. <a class="elsevierStyleCrossRef" href="#bib51">Rjab et al. (2023)</a> investigated the barriers to AI adoption in smart cities, while <a class="elsevierStyleCrossRef" href="#bib0021">Khan, Khan, Khan and Haleem (2023)</a> analyzed big data challenges in smart cities using an integrated fuzzy approach based on Interpretive Structural Modelling (ISM) and Decision-Making Trial and Evaluation Laboratory (DEMATEL). <a class="elsevierStyleCrossRef" href="#bib0038">Paes et al. (2023)</a> reviewed the challenges facing future smart and sustainable cities. These studies collectively suggest that the implementation of big data in smart cities faces significant hurdles, including high investment costs, technical issues like integrating IoT devices, data complexity, and the lack of appropriate technologies and frameworks.</p><p id="para0005" class="elsevierStylePara elsevierViewall">In previous research, there was no comprehensive model that simultaneously examined the barriers and challenges while also considering the optimal solution. Preliminary reviews and research show a gap in comprehensive studies that rank these obstacles and analyze big data solutions specifically for smart cities in developing countries. As an initial innovation, this research intends to identify the obstacles and challenges of implementing big data in smart cities in developing countries in the first phase, and then rank these obstacles using Multi-Criteria Decision-Making (MCDM) methods. In the second phase, solutions to these obstacles will be analyzed using game theory under conditions of uncertainty.</p><p id="para0006" class="elsevierStylePara elsevierViewall">The advantage and innovation of this research lie in the use of an integrated approach combining MCDM and game theory to identify obstacles and determine the optimal solutions to address these obstacles. For this purpose, an integrated MCDM and game theory model in a grey environment will be used. In evaluating the solutions to the obstacles and challenges of implementing big data in smart cities in developing countries, game theory can be employed as an effective analytical tool. In this method, the obstacles are considered as one player and the counter-strategies as another player. Therefore, the advantage of this proposed research method is that the solutions are not merely ranked; instead, the model identifies the optimal solution among all possible solutions. This is crucial as, in the real world, ranking solutions might not be sufficient, and a combination of solutions may better address the problem.</p><p id="para0007" class="elsevierStylePara elsevierViewall">The grey environment comprises quantitative methods that use interval data instead of precise numbers, unlike traditional methods (<a class="elsevierStyleCrossRef" href="#bib0028">Li, Kisacikoglu, Liu, Singh & Erol-Kantarci, 2017</a>). The grey theory, which was introduced by <a class="elsevierStyleCrossRef" href="#bib0015">Deng (1982)</a>, is a mathematical concept widely used in MCDM. This theory is particularly effective in tackling problems involving uncertainty, especially when information is unknown or incomplete (<a class="elsevierStyleCrossRef" href="#bib0012">Cui, Chan, Zhou, Dai & Lim, 2019</a>). Generally, the information about decision-maker's (DMs) preferences regarding criteria is expressed based on their qualitative judgment for various reasons. Additionally, in practice, the judgments of DMs are often uncertain and cannot be expressed with precise numerical values (<a class="elsevierStyleCrossRef" href="#bib0018">KamaliSaraji & Streimikiene, 2024</a>; <a class="elsevierStyleCrossRef" href="#bib0028">Li et al., 2017</a>).</p><p id="para0008" class="elsevierStylePara elsevierViewall">Grey theory is a method used to study uncertainty and incomplete information, and its application in the mathematical analysis of systems with incomplete data is expanding. Unlike precise numerical values, grey numbers explicitly represent uncertainty and inaccuracy. This flexibility allows DMs to incorporate subjective judgments, incomplete information, and varying degrees of importance assigned to different criteria. Grey numbers are similar to fuzzy numbers; however, the key difference is that with grey numbers, the exact value is unknown, but the range within which the value lies is known. In other words, the precise bounds of the left and right intervals of the number are determined and known (<a class="elsevierStyleCrossRef" href="#bib0010">Bouzon, Govindan & Rodriguez, 2018</a>; <a class="elsevierStyleCrossRef" href="#bib0012">Cui et al., 2019</a>; <a class="elsevierStyleCrossRef" href="#bib0029">Li, Zhao, Wu & Qiu, 2022</a>). On the other hand, a fuzzy number depends on a membership function and is defined as an interval whose left and right bounds have unknown values. The computation of the membership function for the upper and lower bounds of a fuzzy number requires intricate computations, which makes calculations involving grey numbers more straightforward than those involving fuzzy numbers.

Safeguarding personal data while enabling data-driven decision-making poses a significant challenge for smart city planners and policymakers. Another obstacle to the successful implementation of big data in smart cities is the lack of interoperability among different data sources and systems (<a class="elsevierStyleCrossRef" href="#bib0005">Ali et al., 2020</a>; <a class="elsevierStyleCrossRef" href="#bib0024">Korczak & Kijewska, 2019</a>; <a class="elsevierStyleCrossRef" href="#bib0040">Razmjoo, Østergaard, Denaï, Nezhad & Mirjalili, 2021</a>). Data silos and incompatible formats hinder the seamless exchange and integration of information from various sources, limiting the effectiveness of data analytics initiatives. The infrastructure required to support big data analytics in smart cities is often inadequate or outdated (<a class="elsevierStyleCrossRef" href="#bib0020">Khan, 2021</a>; <a class="elsevierStyleCrossRef" href="#bib0038">Paes et al., 2023</a>).

However, in contrast to the classical BWM, G-BWM employs grey numbers for these comparisons. Grey numbers are intervals rather than fixed values, and thus they allow the modeling of uncertainty in the DM's judgments. G-BWM solves a series of LP problems that aim to minimize the maximum deviation of the grey comparison ratios from their ideal values (<a class="elsevierStyleCrossRef" href="#bib0009">Bitarafan et al., 2023</a>; <a class="elsevierStyleCrossRef" href="#bib0010">Bouzon et al., 2018</a>; <a class="elsevierStyleCrossRef" href="#bib0012">Cui et al., 2019</a>; <a class="elsevierStyleCrossRef" href="#bib0028">Li et al., 2017</a>; <a class="elsevierStyleCrossRef" href="#bib0033">Mahmoudi et al., 2020</a>; <a class="elsevierStyleCrossRef" href="#bib0044">Ulutaş et al., 2022</a>). The GBWM involves the formulation of an LP model where the objective function aims to minimize the maximum deviation of actual comparison ratios, represented by grey numbers, from the optimal one derived from the best and worst criteria. The constraints included in this LP model are derived from grey comparison matrices that ensure consistency in the relative importance of each criterion within the defined grey intervals (<a class="elsevierStyleCrossRef" href="#bib0010">Bouzon et al., 2018</a>; <a class="elsevierStyleCrossRef" href="#bib0012">Cui et al., 2019</a>; <a class="elsevierStyleCrossRef" href="#bib0028">Li et al., 2017</a>; <a class="elsevierStyleCrossRef" href="#bib0044">Ulutaş et al., 2022</a>). This approach contrasts with traditional methods in MCDM, such as the classical BWM, since, in the BWM, fixed point comparisons lead to a simpler LP model but without the capacity for incorporating uncertainty. In comparing the G-BWM with other MCDM methods from the perspective of LP, its superiority in handling uncertainty by way of grey numbers and robustness in maintaining consistency within the decision model is high. With this, however, comes the price to be paid in additional computational complexity, since solving LP problems with interval coefficients is generally harder than solving those with fixed coefficients (<a class="elsevierStyleCrossRef" href="#bib0009">Bitarafan et al., 2023</a>; <a class="elsevierStyleCrossRef" href="#bib0028">Li et al., 2017</a>; <a class="elsevierStyleCrossRef" href="#bib0033">Mahmoudi et al., 2020</a>; <a class="elsevierStyleCrossRef" href="#bib0044">Ulutaş et al., 2022</a>).</p><p id="para0101" class="elsevierStylePara elsevierViewall">However, the key differences in GBWM concerning the popular weighting methods (e.g., AHP, Simple Additive Weighting (SAW), and Entropy) are the treatment of uncertainty and imprecision, and number of the required comparisons. For example, similar to BWM, AHP is a pairwise comparison that does not inherently address issues of uncertainty. AHP mandates exact numerical comparisons and is prone to inconsistency whenever the judgment of the DM is not perfectly transitive. On the other hand, SAW directly gives the criteria weights according to their order of importance but is found to be lacking in any systematic approach to the occurrence of uncertainty or inconsistency in the process of weighting. The Entropy method used for objective weighting determines weights based on data variation, which does not involve subjective judgment and hence does not handle uncertainty in the subjective sense either. In turn, G-BWM represents such a weighting process with grey numbers, one which is more flexible and robust, especially when the DM is uncertain about the precise importance of the criteria (<a class="elsevierStyleCrossRef" href="#bib0009">Bitarafan et al., 2023</a>; <a class="elsevierStyleCrossRef" href="#bib0028">Li et al., 2017</a>; <a class="elsevierStyleCrossRef" href="#bib0033">Mahmoudi et al., 2020</a>; <a class="elsevierStyleCrossRef" href="#bib0044">Ulutaş et al., 2022</a>). The LP model of this method ensures that derived weights will be consistent with the grey comparisons provided by the DM; hence, more reliable in cases under uncertainty. While this makes it computationally more complicated compared to simpler methods such as SAW or Entropy, its main advantage lies in the fact that G-BWM works in a more articulated way, closer to real situations in which information is often incomplete or imprecise. Hence, mathematically speaking, the ability of G-BWM to integrate uncertainty directly into the weighting process cements its position, as an improved method for decision-making in a complex environment (<a class="elsevierStyleCrossRef" href="#bib0012">Cui et al., 2019</a>; <a class="elsevierStyleCrossRef" href="#bib0028">Li et al., 2017</a>; <a class="elsevierStyleCrossRef" href="#bib0033">Mahmoudi et al., 2020</a>; <a class="elsevierStyleCrossRef" href="#bib0044">Ulutaş et al., 2022</a>).</p><p id="para0102" class="elsevierStylePara elsevierViewall">The CRiteria Importance Through Inter-criteria Correlation (CRITIC) method is an objective weighting technique for which weights are calculated and assigned to different criteria according to the contrast intensity of each criterion, considering variation and the conflict (correlation) that may exist between the criteria. It does not require any subjective input from the DM; rather, it uses data from the alternatives to calculate the weights themselves. This reveals that the CRITIC method essentially needs the presence of alternatives to function properly (since it calculates the weights based on the criteria differentiation capability related to different options). Similarly, the Stepwise Weight Assessment Ratio Analysis (SWARA) methodology stands for a subjective weighting method that involves the DMs in ranking criteria and further adjusting the weights by a successive ratio approach (<a class="elsevierStyleCrossRef" href="#bib0009">Bitarafan et al., 2023</a>; <a class="elsevierStyleCrossRef" href="#bib0010">Bouzon et al., 2018</a>; <a class="elsevierStyleCrossRef" href="#bib0012">Cui et al., 2019</a>). In addition, SWARA usually relies on the presence of alternatives, since DMs assess the importance of criteria based on their impact level on the designated alternatives. The iterative process inherent in the SWARA method, which adjusts the weight of each criterion based on the ranking of the previously assessed criterion, necessitates the existence of alternatives to effectively evaluate the significance of every criterion. Conversely, the G-BWM approach does not depend on the availability of alternatives for the establishment of weights. Rather, it emphasizes the identification of the optimal and least favorable criteria, facilitating comparisons in relation to these two extremes, irrespective of alternatives. This makes G-BWM particularly useful when decision makers must assess the weights of the criteria in advance, or when the alternatives are not defined. Compared to other methods, such as AHP, in the G-BWM and BWM, fewer pairwise comparisons are required, which brings less cognitive load for the DMs and, at the same time minimizes the possible inconsistencies. While the AHP requires a full pairwise comparison matrix against all the criteria, GBWM requires just the comparisons with respect to the best and worst criteria, hence less cumbersome or more effective when the number of criteria becomes large (<a class="elsevierStyleCrossRef" href="#bib0012">Cui et al., 2019</a>; <a class="elsevierStyleCrossRef" href="#bib0028">Li et al., 2017</a>; <a class="elsevierStyleCrossRef" href="#bib0033">Mahmoudi et al., 2020</a>; <a class="elsevierStyleCrossRef" href="#bib0044">Ulutaş et al., 2022</a>).</p></span></span><span id="sec0018" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="cesectitle0021">Improved zero-sum grey game theory</span><p id="para0103" class="elsevierStylePara elsevierViewall">The zero-sum game theory defines scenarios in game theory where one player's gain is exactly equal to the other player's loss.

According to the zero-sum game theory, two players compete in such a way that the benefits gained by one player are exactly offset by the losses of the other players. The model assumes complete information at hand about the system-a situation rarely encountered in reality. IZSGG theory relaxes this assumption by allowing for "grey" factors (uncertain, incomplete, and partially known information) to be taken into consideration, and as such, offers a more realistic modeling of complex competitive environments when complete information is not attainable or even assured. Besides, grey LP can determine the bounds of the optimal values to provide a range of possible solutions rather than just a single answer. This feature is very valuable in solving strategic decision-making problems in which the exact return is not well known. The feasible region is bounded by the lower and upper limits of the grey parameters that mark out the area within which practical solutions should lie. Grey LP would not provide an exact solution with a single point but rather with an interval. An interval solution does imply the uncertainty which is dealt with by the parameters and gives the DMs an interval solution that may turn out to be optimal in different scenarios.</p></span></span><span id="sec0019" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="cesectitle0022">Result</span><span id="sec0020" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="cesectitle0023">Case study</span><p id="para0133" class="elsevierStylePara elsevierViewall">An academic two-phase research methodology is proposed to prioritize the significant barriers to big data adoption for sustainable smart city development.

With a weight of 0.6152, technical barriers are identified as the most critical among the primary obstacles. Within this category, the sub-barrier T3, which pertains to technical and technological limitations, emerges as the most significant with a weight of 0.6746. This indicates a pressing need to address the limitations in current technologies and infrastructure that impede the effective deployment of big data systems. In the context of security, the sub-barrier S3, concerning issues related to data storage and transfer, holds the highest importance with a weight of 0.6411. This underscores the necessity of robust data security measures to protect sensitive information and ensure seamless data flow across systems. Additionally, the sub-barrier M1, related to high environmental investment costs, is notable with a weight of 0.5149, highlighting the financial challenges in adopting environmentally sustainable practices.</p><p id="para0152" class="elsevierStylePara elsevierViewall">Given these findings, it is clear that overcoming technical and technological limitations (T3), which carry the highest overall importance with a weight of 0.39267375, should be a priority. To address these barriers effectively, several practical recommendations can be proposed. Firstly, investing in research and development to advance technological capabilities is crucial. This includes the development of more efficient data processing and storage technologies that can handle the vast amounts of data generated in smart cities. Secondly, augmenting collaboration between public and private sectors can facilitate the sharing of resources and expertise, thereby mitigating the financial burden of environmental investments. Thirdly, implementing comprehensive training programs for personnel can ensure that the workforce is adept at managing new technologies and adhering to stringent security protocols. Lastly, policymakers should focus on creating supportive regulatory frameworks that encourage innovation while ensuring data security and environmental sustainability. By addressing these critical barriers, the deployment of big data systems in smart cities can be significantly improved, paving the way for smarter, more efficient urban environments.</p><p id="para0153" class="elsevierStylePara elsevierViewall">The game theory analysis of necessary measures for a smart city reveals critical insights into key areas that require attention. Among these, (Traffic Flow Management), (Public Transportation Optimization), and (Waste Management) stand out as vital components. Specifically, for Traffic Flow Management, the lower bounds are set at 0.99 and the upper bounds at 0.318, indicating a significant range that necessitates robust strategies to optimize vehicle movement and reduce congestion. For Public Transportation Optimization, the lower bounds are 0.271 and the upper bounds 0.090, suggesting that there is room for substantial improvement in enhancing the efficiency and effectiveness of public transit systems. Lastly, Waste Management, with lower bounds at 0.403 and upper bounds at 0.101, highlights the importance of effective waste collection, disposal, and recycling processes to maintain urban hygiene and sustainability.</p><p id="para0154" class="elsevierStylePara elsevierViewall">To address these measures effectively, targeted strategies should be implemented. For Traffic Flow Management, investing in smart traffic lights, real-time traffic monitoring systems, and adaptive traffic control technologies can significantly reduce congestion and improve flow. In the realm of Public Transportation Optimization, integrating smart ticketing systems, real-time tracking of public transport vehicles, and improving connectivity between different modes of transport can make public transit more attractive and efficient for residents. For Waste Management, deploying smart bins that signal when they need emptying, enhancing recycling programs, and utilizing waste-to-energy technologies can improve waste processing efficiency and environmental sustainability.</p><p id="para0155" class="elsevierStylePara elsevierViewall">The worst-case scenario for a smart city involves the simultaneous occurrence of several risks, including issues related to “Sharing Data and Information”, “Collecting and Recording Data”, “Technical Limitations and Technology”, “Non-cooperation of Organizations”, and “Issues Related to the Interpretation of Complex Information”.

The analysis of barriers to implementing big data systems in smart cities reveals significant challenges, particularly in the realm of technical constraints.</p><p id="para0158" class="elsevierStylePara elsevierViewall">Overcoming the challenges of adopting big data within sustainable smart cities requires a well-framed strategy from both technical and managerial perspectives, especially using optimized methodologies such as Lower-Bounded Traffic Flow Management, Public Transportation Optimization, and Waste Management. In such regard, traffic flow management with lower bounds refers to the area of using big data analytics for real-time prediction and regulation of traffic, with a guarantee that congestion is minimized and the flow within the transportation network is well managed. This methodology utilizes historical traffic information, meteorological factors, and real-time sensor data in simulating and optimizing the flow of traffic, therefore reducing both travel time and emission. Managerially, this strategic solution involves integrating multifarious sources of data by urban planners, transportation agencies, and information technologists to ensure that the traffic management systems work efficiently. The infrastructure investments would be primarily in smart traffic lights, sensors, and computing. These investments would include setting up a central data platform, real-time analytical information dissemination to build stakeholder collaboration, and informing the public about the use of various public transport systems as much as possible.</p><p id="para0159" class="elsevierStylePara elsevierViewall">Public transport improvements are thereby enabled through large data sets that constantly update and optimize routes, schedules, and various transit capacities to maximize such an experience of reduced waiting time, increased reliability of service, and overall efficiency. If public transport systems could handle passenger flows, demand patterns, and operational performance indicators, it would better serve the needs of the population. Only proper governance can oversee planning, implementation, and continuous improvement if optimization is to be truly effective. Key measures therein would be data analytics focused on route optimization, capacity management through dynamic pricing or demand-responsive services, real-time passenger feedback mechanisms, and alignment with sustainability objectives through low-emission vehicles and multi-modal options. Big data allows for massive improvements in smart city waste management through optimizations of routes for waste collection, predicting waste generation patterns, and improving recycling rates. Waste bin fill-level can be tracked by sensors, while data analytics can plan collection schedules and routes for minimal fuel consumption and operational costs. Again, effective waste management does call for strong managerial coordination across departments, public awareness drives, and adherence to sustainability-focused policies. Implementation of predictive analytics of the waste generated, deployment of smart sensor bins, analysis of the effectiveness of recycling programs, and public education campaigns are pragmatic approaches toward waste management. All these need to be integrated into one single urban planning framework for a sustainable data-driven smart city. The focus shall be on technological solutions such as real-time analytics, predictive modeling, and sensor-based monitoring, combined with strong managerial oversight. It will be enabled through a focus on data integration, collaboration among stakeholders, public engagement, and continuous improvement. Eventually, it will improve urban sustainability and the quality of life of its citizens by making cities more efficient, resilient, and adaptive to future challenges.</p><p id="para0160" class="elsevierStylePara elsevierViewall">Technical barriers, identified as the most critical barriers with a weight of 0.6152, highlight the pressing need to address limitations in current technologies and infrastructure.

In the context of security, issues related to data storage and transfer (sub-barrier S3) are crucial, with a weight of 0.6411, underscoring the necessity for robust data security measures. Additionally, high environmental investment costs (sub-barrier M1) pose financial challenges, with a weight of 0.5149. Addressing these critical barriers requires a multifaceted approach.

Mitigating these risks requires improving data security protocols, standardizing data collection practices, continuous investment in technology, promoting organizational collaboration, and developing advanced analytical tools. In such a scenario, even minor disruptions in technology can cascade into broader operational failures, exacerbating the other risks and creating a complex web of issues that are difficult to resolve. Therefore, smart cities must prioritize overcoming these technical and technological barriers to safeguard their operations against such worst-case scenarios. By addressing these measures and mitigating identified risks, smart cities can improve their resilience and effectiveness, leading to improved urban living conditions and sustainable development. The findings underscore the necessity of advancing technological capabilities, enhancing collaboration between public and private sectors, implementing comprehensive training programs, and creating supportive regulatory frameworks. Additionally, the game theory analysis identified critical areas such as traffic flow management, public transportation optimization, and waste management as vital components for smart city development. By investing in smart technologies, improving data security, promoting organizational cooperation, and addressing financial and technical challenges, cities can overcome these barriers and enhance the deployment of big data systems.</p><p id="para0162" class="elsevierStylePara elsevierViewall">IZSGG utilizes the theories of grey numbers and grey matrices in the representation of uncertainties involved with the payoff matrices of the game. That will, in turn, enable the derivation of strategies incorporating the fuzzy nature of some elements in the system. This, in turn, enables the IZSGG theory to capture a wider range of scenarios, including cases of partial or incomplete knowledge about specific facts. Thus, the IZSGG theory is more applicable to realistic situations that require decisions based on incomplete information. The theory further utilizes advanced optimization techniques in determining the points of equilibrium, which are informed not only by established values but also take into consideration the grey components of those values, hence providing a more refined solution to the game. One key advantage of the IZSGG with respect to the traditional Zero-Sum Game theory is the ability to deal with uncertainty and incomplete information, something that often characterizes realistic applications. Unlike the usual method, which might give too optimistic or pessimistic strategies due to the assumption of full information, IZSGG offers more robust and realistic strategic solutions that take into account and integrate all ambiguities imbued in the data.</p><p id="para0163" class="elsevierStylePara elsevierViewall">Ultimately, this approach will lead to more efficient, resilient, and sustainable urban environments, paving the way for the future of smart cities. Future research could focus on developing advanced data processing and storage technologies that are more efficient and scalable. Another important area is the creation of robust regulatory frameworks that balance innovation with data security and environmental sustainability. Moreover, future research must examine the integration of emerging technologies, such as artificial intelligence and the IoT, to enhance smart city infrastructure and services.</p></span><span

optimization of sustainable smart cities is an essential endeavor in modern urban development, aiming to enhance the quality of life for citizens while minimizing environmental impacts. Big data plays a critical role in achieving these goals by enabling the collection, analysis, and utilization of vast amounts of information to make informed decisions. However, implementing big data in smart cities faces significant barriers, including data-sharing challenges, technical limitations, and organizational non-cooperation. Addressing these barriers is crucial for the successful deployment of smart city initiatives. We propose a novel approach to tackle these challenges using the Improved Zero-Sum Grey Game (IZSGG) theory and the Grey Best-Worst Method (G-BWM). This method comprehensively analyzes the risks and uncertainties associated with big data implementation in smart cities. By modeling the interactions between different stakeholders and their competing interests, IZSGG theory provides a framework to identify optimal strategies for data management. The G-BWM further refines these strategies by evaluating and prioritizing the various factors influencing big data utilization. Our findings reveal that the worst-case scenario for a smart city involves the simultaneous occurrence of several risks, all of which have positive values, indicating their potential to significantly disrupt smart city operations. The specific risks identified include: the sharing of data and information, the collection and recording of data, technical limitations and challenges associated with technology, the non-cooperation of organizations, and issues related to the interpretation of complex information. The technical barrier is the most significant with a weight of w(T)=0.6152, indicating its critical role compared to other barriers. Within this category, the sub-barrier of technical and technological constraints is particularly critical, with a weight of 0.39267375.</p></span>" ] ] "multimedia" => array:75 [ 0 => array:8 [
