the index is excellent by the malmquist index as extended to productivity measurement. the index developed here is defined in terms of input cost rather than input quantity distance functions in supply chain. therefore, we propose productivity change is decomposed into overall efficiency and cost technical change. these decompositions provide a clearer situation of the root sources of supply ch...

Perishability of blood products as well as uncertainty in demand amounts complicate the management of blood supply for blood centers. This paper addresses a mixed-integer linear programming model for blood platelets production planning while integrating the processes of blood collection as well as production/testing, inventory control and distribution. Whole blood-derived production methods for...

in this article, a finite horizon, multi product and multi period economic order quantity like seasonal items is considered where demand rate is deterministic and known but variable in each period. the order quantities of items come in batch sizes and the end of the period order quantity and, consequently, demand of customers are zero. in addition, storage space is constrained and the problem ...

Supply chain management helps partners in the chain to justify internal costs. The pursuit of cost information through the supply chain is very important for controlling costs, which helps to establish and optimize activities in institutions in the value chain. In this research, we have tried to review the literature on Supply Chain Costing in order to predict a model of management dashboard de...

This paper studies a decentralized supply chain in which a manufacturer sells a common generic product through two traditional and online retailers under free riding market. We assume that the traditional retailer provides the value added services but the online retailer does not. Factors such as retail prices, local advertising of the retailers, global advertising of the manufacturer and servi...

pricing policies play an important role in water demand management and its optimal allocation. determining proper water price leads to optimal allocation of water especially in agricultural consumptions. applying new subsidy targeting law in iran which insists on pricing water based on its supply cost, will effects considerably on water resource management in agriculture sector. so, in this stu...

In this research, the optimal pricing decisions for two complementary products in a two-echelon supply chain under two scenarios are studied. The proposed supply chain in each echelon includes one retailer and two manufacturers and the same complementary products are produced. In the first scenario, we assume the unit manufacturing costs of the complementary products in each echelon are the sam...
