## 5 Managerial and Policy Implications  
Supply chain management is a complex operation for the production and service systems in order to operate the flow of materials, information and finance to the final customer. On the other hand, risks and disruptions negatively impact the supply chain operations. So, the potential risks should be considered in logistics operations. Along the same lines, a business-continuity plan is crucial to enhance the business' resilience against possible risk and provide a sustainability assessment. Further, sustainable logistics operations are inevitable because of environmental awareness, several restrictions and decreasing global emissions by using environmentally friendly vehicles. For all reasons, sustainability and risk assessments are addressed to provide efficient logistics operations when Sustainable Development Goals are successfully achieved. Economic, safety and hazards risk criteria are the top three main criteria based on the introduced fuzzy AHP, which is part of the integrated method. When designing a logistics network, the volatility of price costs, mortality caused by traffic injury and epidemics should be comprehensively investigated due to the efficiency of logistics operations. Otherwise, the risks and disruptions may affect the companies and cause them to lose their market shares. Renewable energy is also vital for reducing emissions and providing requirements for environmental concerns. Notably, the information technology infrastructure is essential to manage information flows for logistics networks. Based on the fuzzy-based AHP results, the green number of vehicles is a significant sub-criterion. So, the number of environmentally friendly vehicles should be increased to operate sustainable logistics \begin{table}

Policy-makers may consider evaluating sustainable and risk performance pillars in order to achieve successful logistics operations. Therefore, the potential risks and disruptions may be eliminated for the producer, investors and consumers. Logistics centers in cities should minimize their exposure to hazards and risks to benefit logistics network operations. Further, based on the case study results, Istanbul is the most appropriate location for logistics centers. However, policy-makers should focus on the safety, hazards risk and environmental impact and utilization main pillars for Istanbul in order to increase OPS and eliminate negative effects. Sustainable Development Goals (SDGs) [19] are investigated based on the results of this study.
