Introduction
Today, small and medium enterprises are considered as major factors in the growth of the industrial structure of the country, and they are very important in a lot of developing countries' industries that sought to revive their economic structure. ese countries have understood that in order to speed up the process of industrialization, priority should be given to the development of small and medium industries and not big industries. For this reason, we have an unprecedented enthusiasm of the small industries in many different countries [1]. e most important advantages that make economic policies to focus on small and medium industries are as follows: first, training of capable managers in the competitive environment [2]; second, making an effective role in entrepreneurship and job creation, resulting in increased exports and high functionality, and at the same time, adapting to the policies of downsizing, outsourcing, and reengineering [3]. Developing has been futile [4,5]. In our country, in despite of the huge number of small industries, there are failures in their industrial structures, as they are not able to do effective roles as small industries in developed and developing countries. [4][5][6]. High cost of production in Iran, the weakness of the banking system, problems in taxation and customs issues, and inadequate financial support are things that undermine these firms, decline production, and take them of the production system [4]. e law of subsidies is one of the most important components of the economic development plan that has significant impacts on the industrial sector. Hence, this study aims to identify the main challenges that concerns recognizing challenges of subsidy for small and medium-sized manufacturing enterprises in relation to the development of their activity. e article focuses on subsidy and economic firms and 30 important challenges and their priorities that firm encounter. In the last part, the major findings and recommendations are presented. erefore, main contributions of this study are as follows: (i) Identify the challenges facing industries after government subsidies (ii) Ranking and determining the most important challenge facing industries after government subsidies using multiple criteria decision making (MCDM) e rest of this study is organized as follows. In Section 2, basic issues such as the concept of subsidies, types of subsidies, subsidy goals, sustainable development literature review, and motivation and contribution are presented. In Section 3, methodology and the VIKOR decision-making method are explained. In Section 4, the results are presented. In Section 5, the managerial insights and main limitations of the research are presented, and finally, in Section 6, an overall conclusion is presented.

Literature Review
In this section, the impact of successful implementation of targeted government subsidies for sustainable development is reviewed. Sustainable development can be defined as the practice of maintaining the productivity by replacing resources used with resources of equal or greater value without degrading or endangering natural biotic systems [7]. Sustainable development binds together concern for the carrying capacity of natural systems with the social, political, and economic challenges faced by humanity. Sustainability science is the study of the concepts of sustainable development and environmental science. ere is an additional focus on the present generations' responsibility to regenerate, maintain, and improve planetary resources for use by future generations [8,9]. For this purpose, Liu et al. [10] presented the evolutionary dynamics in China's electric vehicle industry for taxes and subsidies. In this study, the production fluctuation in electric vehicle (EV) industry is explained by evolutionary game. e optimal decision of two players and Nash equilibrium is derived in three decision scenarios. Also, the influence of government intervening in consumer demand and vehicle supply on EV industry development path is examined. Finally, results show that the policy of dynamic emission taxations and static subsidies is more effective in the EV industry development. Kumar et al. [11] evaluated the effectiveness of fisheries subsidies as a trade policy tool to achieving sustainable development goals at the WTO. To this end, this study provides possible implications of the fisheries subsidies as a trade policy tool for market access and its effectiveness in achieving the overall sustainable development goals. To examine the effectiveness of subsidies in fisheries negotiations, the study focuses on the global supply and demand side of the fisheries resources from the perspective of the fish resource holders and the fishing resource capacity. Using both the market demand and supply for fisheries resource extraction, the study examines the effectiveness of subsidies as a trade policy tool to attain the overall sustainable development goals. Based on the analysis, certain policy strategies follow, which are important for countries to consider before the elimination of fisheries subsidies at the WTO. Moghaddam and Wirl [12] determined the oil price subsidies in oil and gas exporting countries. According to the political policy, it is easy to grant subsidies but much more difficult to remove them. High oil revenues tend to raise subsidies and make abolishing them more difficult. erefore, without proper policies, domestic demand will explode. Grilli and Murtinu [13] considered selective subsidies, entrepreneurial founders' human capital, and access to R&D alliances. Because, selective subsidies help new technology-based firms (NTBFs) access R&D alliances and also apply both R&D alliances with other firms and R&D alliances with public research organizations/universities. Founders' technical education is a key determinant for NTBFs to get the first selective subsidy. Findings show that founders' previous industry-specific work experience positively moderates the impact of subsidies on the likelihood to form a corporate R&D alliance. orne and Hughes [14] evaluated the effectiveness of electric vehicle subsidies in Canada. In this study, the cost-effectiveness of achieving emissions reductions through EV subsidy programs is evaluated with respect to each provincial electricity system in Canada. ese results were then used to compare the costefficiency of EV subsidies to other investments in climate change mitigation initiatives, and ultimately decide whether EV subsidies are feasible to implement in any of Canada's provinces. Solarin [15] examined the factors affecting energy intensity to sustainable development and its components such as electricity intensity, oil intensity, gas intensity, and coal intensity. In this study, special attention is paid to the roles of the fossil fuel subsidies, which include total fossil fuel, fossil-fueled electricity, oil, gas, and coal subsidies in developing countries. Using a generalized method of moments approach, it is shown that increase in fossil fuel, electricity, oil, gas, and coal subsidies promote energy intensity or its component elements. e results further suggest that urbanization, industrialization, and foreign direct investment also promote energy intensity. Also, it is noted that real gross domestic product per capita and human capital development have negative impact on energy intensity and its components. Moreover, the countries are clustered according to their income level, and the relationship in the variables is reexamined in each of the clusters. e results are not substantially different to those obtained for the total sample. e implications of these empirical findings are analyzed in the study. e priority development of public transport cannot be achieved without the support of the government's fiscal and taxation policies, while the implementation of the subsidy policy is the joint effect of multiple stakeholders. For this purpose, Zhang et al. [16] analyzed the implementation mechanism of public transport subsidy policy from the perspective of carbon emission to discuss the evolutionary stability strategy of tripartite game under different situations, thereby, clarifying the key factors affecting the evolutionary path of the stability strategy through simulation. e main conclusions achieved are as follows. (1) When the subsidy and sunk cost are greater than the improper profit brought by the false report and the travel cost (time and economy) of public transport is greater than that of the individual motorized travel combined, the three will eventually arrive at the state in which government chooses no-audit, the enterprise chooses true report, and the resident choose public transport. (2) More government supervision can help reduce the false reporting behavior of public transport enterprises in the implementation of public transport subsidy policy. (3) e punishment and the improper profit brought by the false report are also the key factors that influence the behavior decision-making of the government and the enterprises. (4) e economic cost of travel plays an important role in the evolution path of residents' stabilization strategy, yet is of little significance on the behavior decision of enterprises and governments. From the perspective of sustainable transportation development, it is necessary for the government to control or even reduce the ticket price of public transport and to increase the economic cost of individual motorized travel. Increased stress on environmental pollution, resource consumption, and public health resulting from the rapid growth of kitchen waste (KW) necessitated a disposal way of recycling and reuse. erefore, Shi et al. [17], in their study, considered three disposal lines to convert KW into clean and renewable energy products, during which a Stackelberg equilibrium-based model is developed to achieve a balance between cost savings, carbon emissions reduction, and profit making by considering the interests of the local government and KW disposal plants. Recently, the outbreak of the COVID-19 pandemic poses great challenges to the current government subsidy models in the renewable energy sector for recovering in the postpandemic economy. Although, many subsidy models have been applied to accelerate renewable energy investment decisions. However, it is important to develop a new model to ensure the sustainability of the renewable energy supply network under disruptions on both the supply and demand sides due to hazardous events. For this purpose, Tsao et al. [18], in their study, investigated different subsidy models (renewable credit, supplier subsidy, and retailer subsidy) to find a win-win subsidy model for sustainable energy supply under disruption risks. e objective is to determine the optimal capacity of renewable energy added to the grid, the optimal wholesale price of the power plant, and the optimal retail price of the aggregator under different subsidy models to maximize the economic, social, and environmental benefits of the whole network. A novel scenario-based robust fuzzy optimization approach is proposed to capture the uncertainties of business-as-usual operations (e.g., some relevant costs and demand) and hazardous events (e.g., COVID-19 pandemic). e proposed model is tested in a case study of the Vietnamese energy market. e results show that for a high negative impact level of hazardous events on the supply side, the renewable credit and supplier subsidy models should be considered to recover the renewable energy market. Furthermore, the proposed approach has a better performance in improving the power plant's robust profit for most of the hazard scenarios than the robust optimization model. Song et al. [19] evaluated the effects of government subsidies on the sustainable innovation of university-industry collaboration. is research shows that members in the universityindustry collaboration who receive the government subsidy will produce more profit and also concluded that the government subsidy rate is negatively related to the consumer demand impact coefficient. erefore, with the same level of effort, enterprises receiving government subsidies will generate greater social welfare. Finally, these study results can help governments to define sustainable innovation subsidy policy. Table 1 provides the research literature by the method, industry, and considered characteristics.

Motivation and Contribution.
According to the abovementioned, studies have generally focused on identifying economic challenges and their impact on subsidies in each industry. Based on the knowledge gained, there are few studies that pay attention to both identification and ranking challenges. erefore, the valuable contributions of this study are as follows: (i) Identify the challenges facing industries after government subsidies (ii) Ranking and determining the most important challenge facing industries after government subsidies Based on main contribution of this study abovementioned, the main research questions are as follows: (i) What are the main challenges facing small and medium enterprises after the implementation of targeted subsidies from an economic perspective?
Mathematical Problems in Engineering (ii) What are the priorities the small and medium enterprises subsidies challenges?
3. Methodology Figure 1 shows the proposed framework of the research. is study is a descriptive and exploratory research based on surveys of experts. It is an applied research and uses the descriptive study, with the data field of the library from two ways: (i) libraries (search, study, and use of documents, texts, magazines, and newspapers economy) and (ii) other than libraries (preliminary interviews and questionnaires) to extract the indicators of population, and then with surveys of experts and specialists authorities, it weighs and ranks the challenges done. To do the research, a list of experts has been made to conduct research in Hamedan province with the help of industrial estates in connection with managers of government agencies and the private sector on the other hand. Totally, 25 experts declared their readiness to respond to the questionnaire. Most of the questionnaires have been spread among managers and experts who are fully informed about problems of production in Hamedan (in Iran) and who were aware of policies in the field or who were the supervisors or executors of governmental plans. e experts enjoy the following major features: (i) ey have no formal training and were less than undergraduate level, so half of them had bachelor, other half at the graduate level, and one at the PhD level. (ii) People in the group of measuring the value had at least 14 years' experience in different and associated fields. So in one hand, they were informed about documents, rules, and policies of states in the field of production, and on the other hand, they were related to the managers of production companies, and sometimes, they had some collaboration and management in production. (iii) Having diversity of work experience in various fields e method used in this research is VIKOR. VIKOR, a compromised MADM method, was developed in 1998 based on LPG.
is multicriteria decision-making method is created for solving a discrete decision problem with disproportionate measures (different measurement units). is method focuses on ranking and selecting an alternative category and determines compatible solutions to the problem even with conflicting criteria. It can help decision makers to reach to a final decision. Compliant solution is a feasible solution that is the closest to the ideal solution.
Compatibility means the answer which is made by the (i) Necessarily, in the model, we do not require using expert' opinions to evaluate options based on criteria, and we can use raw data. For example, in the criteria of "connection way" to evaluate which village has a suitable condition, we can measure the connection way to the village and put it in the model, without using the experts' opinion. is evaluation can be based on raw data or based on expert opinion. e aim of this model is to determine the weight and value of each option and rank them. ere is no need to complex software, and considering that in all the parts, the mathematical formulas have been used, and we can use Excel software to realize the goal [20]. (ii) e VIKOR method uses linear normalization and the TOPSIS method uses vector normalization. In VIKOR method, the normalized amount does not depend on the criteria measure unit. However, in the TOPSIS method, the normalized amount depends on the criteria measure unit.
To evaluate the risk in most of the resources, only two criteria, "probability" and "effect" of risk, have been used, while some other resources use "risk control criteria" or "eliminate risk criteria." In this study, all three criteria are considered for ranking the challenges as risks.
ere are several methods for risk assessment, including FMEA (failure modes analysis and its effects), FMECA (analysis of critical scenarios and consequences of it), HAZOP (analysis of the associated risks with the process), and FTA (tree hazard analysis). But the most valid method is FMEA which is first used by America's military to decrease the risk management as well as the risks of natural disasters' damages [21]. is method is used to predict and prevent errors [22]. e prediction is done by experts who have enough knowledge and experience about the design process or service. According to [23], the advantages of this method are as follows: (i) Assessing the current situation (possible risk control) (ii) A more accurate and realistic risk assessment methods than the traditional methods (iii) A reliable method for predicting risk and managing preventive solutions

VIKOR Method.
e VIKOR is a method developed by Opricovic in 1998. It is based on the definition of the vector of weights for the established criteria based on expert knowledge [24].
is approach obtains in the next steps, after certain transformations, the closeness of the solution to the ideal solution. Based on this distance, the final ranking is determined, assessing the quality of the alternatives tested. e result obtained may largely depend on the weights for the criteria defined at the beginning [25]. e vector of the weights specified by the expert should meet the following condition: Each of the criteria is initially defined as a cost or profit type of criteria (2). e cost type shows that we want it to achieve the lowest possible values, while the profit type should achieve the highest possible values.
For each of the criteria, the best f * i and the worst f * i values are defined. en, using equation (3), preference values for each criterion are calculated, taking into account the weights for criteria defined at the beginning. On this basis, the closeness to the ideal solution is calculated, considered in three different rankings calculated from the following formulas (4)-(6) for S, R, and Q, respectively.
e VIKOR method is useful, especially in situations when a decision maker cannot express his/her preference. Even if the achieved ranking is not as accurate as the decision maker expects it to be, the weights for each criterion could be redefined. All processes could be performed once more to check if the obtained results are closer to the expected ranking. Moreover, this method provides results that depend on the ideal solution, which stands only for the given set of alternatives. It means that changing the group of alternatives and their values for specified criteria would affect receiving an utterly new preference ranking in which position for each option can differ in comparison with the one received in the previous attempt.

Criteria
Identifying. In this study, three criteria are considered for ranking choices. All three criteria are selected from literature, as given in Table 2.

Results
e data were collected from questionnaires; first, we calculate the weight of normalized criteria through arithmetic mean. Table 3 provides the pairwise, normalized, and weight of the criteria, possibility to happen, amount of risk, and possibility to control. According to Table 3, the normalized values are between zero and one, and the sum of the weights obtained is equal to one. Second, the decision matrix is given in Table 4. Also, the results of the calculations made to VIKOR are given in Table 4; then, the challenges in order of priority of importance criteria are determined.
According to Table 4, value of f * i and f * j is calculated. Use f * i and f * j based on the VIKOR method w j · ((f * for each criteria calculated, as given in Table 5, respectively.
According to Table 5, the calculated values of S are given. Based on the results, the value of S depends on the weight of the criteria. When criteria weight is greater than each other, value of S is greater. Finally, Q as the VIKOR index is calculated for each criterion, as given in Table 6.
According to the indicators obtained from the VIKOR method, the option with the highest value is chosen as the most important option [30], based on the output obtained from Table 6, it can be concluded that amount of risk has the highest priority rank; therefore, it has been identified as the first challenge. Similarly, the possibility to happen and possibility to control in manufacturing firms were identified as the next challenges.    Table 7 provides the value of new weight according to Δw � w old − w new � ± 0.05. Also, Table 8 provides the value changed for the new weights. Based on the calculated results, if the weight increases, the S values will increase. Consequently, in such condition, the value of the VIKOR index (Q) also increases.

Managerial Insights
According to the results, study findings can add valuable knowledge to managers. Based on the results, in addition to identifying the challenges facing small and medium industries in granting government subsidies, ranking and selection of important choices has been done. In addition to the valuable results of this study, there are limitations that include the following: (i) In this study, a questionnaire was used to find the background; as a result, some people may refuse to provide a real answer and give an unreal answer. (ii) is research has been done cross-sectionally. Because of this, it makes it difficult to draw conclusions about causality. (iii) e large number of questions in the questionnaire led to the prolongation of its implementation time, which did not affect the accuracy of the participants' answers

Conclusion
Currently, industry faces many problems such as production expense that increases raw material expense, payments, and the price of energy transporter. Generally speaking, different sectors experience different effects, but virtually, all sectors will be affected. If a firm is not a big energy user, it may be affected by an energy user firm or the high payment of its human resource, as they need more money to work. e increased costs will reduce profit margins, unless permission is given to raise prices in relation to increased costs. e results showed that the most important challenge small and medium enterprises face is exchange rate volatility after the targeted subsidy and lack of space in between the challenges of innovation and creativity. Consider that removing subsidies and later increased price of energy transporter causes increasing production expense and decreases margin profit of small and medium firms.
