Because the risk factors cannot be accurately measured it is very difficult to evaluate the risk of supply chain. By introducing hesitancy degree into the risk evaluation process, an intuitionistic fuzzy model is developed to describe the problem. With this model, an algorithm is proposed to evaluate the risk of supply chain. Example shows that the proposed method is superior to the existing ones...
With the development of the information and internet technology, Vendor-Managed-Inventory (VMI) has been adopted by more and more companies. In this paper, a two-echelon supply chain inventory decision model is discussed. The products are perishable and sold over a single selling season. First a VMI model is constructed, and the supply chain members' optimal decisions are gained. Under VMI, the supplier...
Supply chain system is a dynamic network system with fuzzy edge, and how to assess the risks of this system has become the bottleneck of enterprises management. In the light of the influence diagram theory, this paper builds a risk assessment model of supply chain from the topology layer and function layer. The model graphically describes the elements of risk assessment process and takes into account...
Behavioral issues become one of the main concerns of research on supply chain coordination. Within the frame-work of behavioral decision theory, the impact of reference point and gains risk aversion/losses risk seeking effects is respectively investigated on supply chain performance under Pareto optimality criterion. It indicates that for the former the relative risk of losses in supply chains is...
Order allocation is one of the most critical activities of purchasing management in a supply chain. It is an unequally important multiple criteria decision making problem including cost, quality, delivery and service etc. In real situation, much input information is uncertain. In these cases the theory of fuzzy sets and stochastic theory are two of the best tools for handling this problem. Our fuzzy...
Risk management is very important to supply chain management. Managers can reduce supply chain risk by operations management and financial management. Many researchers studied the supply chain risk by using operations management, but only a few authors analyzed financial management applied to risk management of supply chain. Few researchers use the real options as a tool to study supply chain risk...
