introduction agricultural research is important and one of the determinant factors of development of technologies in agricultural sector. among agricultural research disciplines, breeding programs, especially, wheat breeding programs are one of the applied approaches in improving of production and food security. based on a study by byerlee & traxler (1995), economic benefits and internal rate o...

abstract: an efficient supply chain system operates under a strategy to minimize costs by integrating the different functions inside the system and by meeting customer demands in time. in this paper, an integrated supply-production and distribution planning (spdp) is considered despite the fact that in most of the papers, part of the supply chain has been studied, not all parts. therefore, we d...

This paper studied pricing, service level, and production quantity decision problems in a supply chain with one manufacturer and one retailer under demand and production cost disruptions. The joint impact of demand and production cost disruptions on optimal pricing, service level, and production decisions in centralized and decentralized supply chain was analyzed, respectively. By solving the o...

The network management within supply chains requires a systematic cost oriented tool to measure and manage the transactions between the partners. Therefore a supply chain performance measurement was developed, that considers all cost of selection, acquisition, use, administration, maintenance and disposal. It can be used for determining what a particular purchase really cost the organization – ...

A multiobjective optimization model integrating with high-resolution geographical data was applied to examine the optimal switchgrass supply system in Tennessee that considers both feedstock cost and greenhouse gas (GHG) emissions in the system. Results suggest that the type of land converted into switchgrass production is crucial to both plant gate cost and GHG emissions of feedstock. In addit...

The article studies, with the level constraints in short supply, the inventory decision model of the minimum total annual cost of the supply chain which, composed of a single supplier and multiple buyers, involving supplier’s lead time as a decision variable, replacing the cost of shortages with the level in short supply, and has solved the difficult problem in the practice.
