Fuzzy Parameters and Their Arithmetic Operations in Supply Chain Systems

Coordination and profit sharing in a two-level supply chain under periodic review inventory policy with delay in payments contract

In this paper,a coordination model has been investigated for a two-level supply chain (SC) consisting of one retailer and one supplier under periodic review inventory system. The review period and the retailer’s safety factorare assumed to be decision variables. The retailer faces stochastic demand following a normal distribution with known mean and variance. Moreover, it is assumed that unmet ...

Design of supply chain in fuzzy environment

Nowadays, customer expectations are increasing and organizations are prone to operate in an uncertain environment. Under this uncertain environment, the ultimate success of the firm depends on its ability to integrate business processes among supply chain partners. Supply chain management emphasizes cross-functional links to improve the competitive strategy of organizations. Now, companies are ...

Lead Time Demand Modeling in Continuous Review Supply Chain Models

This paper introduces a mixture distribution approach to modeling the probability density function for lead time demand (LTD) in problems where a continuous review inventory system is implemented. The method differs from the typical “moment-matching” approach by focusing on building up an accurate, closed-form approximation to the LTD distribution from its components by using mixtures of trunca...

Closed loop supply chain network design with fuzzy tactical decisions

One of the most strategic and the most significant decisions in supply chain management is reconfiguration of the structure and design of the supply chain network. In this paper, a closed loop supply chain network design model is presented to select the best tactical and strategic decision levels simultaneously considering the appropriate transportation mode in activated links. The strategic de...

Supply chain coordination with quantity discount policy

This paper develops a model for illustrating how to use quantity discount policy to achieve supply chain coordination. A supplier–buyer system selling one type of product with multi-period and probabilistic customer demand is considered. We first show that if both the buyer and supplier can find a coordination mechanism to make joint decisions, the joint profit in this situation is more than th...
