The best service systems aren't just cost-effective. They also respond quickly, handle smoothly and recover promptly from disruptions. This paper proposes a linear piece-wise recovery function and applies it to the decision-making processes of improving a service system's resilience to disasters. A numeric example is developed to demonstrate the proposed model enables tradeoff between a cost minimum...
Decision making support has become essential to conduct an effective management and operational system. It is considered an important part of operational research and management science. There are various decision issues concerning the good governance and management of a supply chain. In this paper, we focus on the conception problem of a supply chain, especially the geographical location implementation...
Considering a two-layer service supply chain consisting of a service provider and a service integrator, and given service demand is influenced by both price and advertising level, mathematical models of decentralized service supply chain, centralized service supply chain and modified decentralized service supply chain based on cost sharing contract are built. Comparing the optimal decisions of the...
This paper is aimed at presenting a linear programming model based on fuzzy set theory. We use linguistic values to assess weights and ratings of supplier selection criteria. And then a hierarchy multiple model based on fuzzy set theory is expressed. According to the fuzzy positive-ideal solution and fuzzy negative-ideal solution, we create the linear programming model which is suited for multi- supplier...
