in this paper a two-stage supply chain with a buyer and seller have been studied. it is assumed that lead time is probabilistic and demand is fixed. in the decentralized model it can be observed each supply chain member try to make the decision to maximize their profits and it will effect on the other members of supply chain and in the comparison with centralized model with assuming the seller ...

The Viburnum Trend mining district in southeast Missouri, USA is one of the largest producers of lead–zinc ore in the world. Previous stream surveys found evidence of increased metal exposure and reduced population densities of crayfish immediately downstream of mining sites. We conducted an insitu 28-d exposure to assess toxicity of mining-derived metals to the woodland crayfish (Orconectes hy...

In this paper, using supply chain operational reference, the reliability evaluation of available relationships in supply chain is investigated. For this purpose, in the first step, the chain under investigation is divided into several stages including first and second suppliers, initial and final customers, and the producing company. Based on the formed relationships between t...

This position paper describes the objectives of project “SFIDA” (cofunded by the Italian Government), aiming at developing a GRID-based interoperability platform able to support next generation Supply Chain Management applications specifically addressing the needs of SMEs belonging to industrial districts and dynamic supply networks. Next generation SCM applications are intended in SFIDA to be ...

today, due to the direct and reverse logistics plays an important role in reducing the costs in supply chain. in this paper, in order to provide a closed-loop supply chain network including supply centers, production, distribution, collection, recycling and disposal of a used linear mixed integer programming. this paper to consider multi-period and multi-product in multi-level supply chain and ...

heavy metal concentration in the soils and sediments has increased worldwide during the last century due to the mining, smelting, and industrial activities. the forumad chromite deposit is located in the sabzevar ophiolitic complex (soc), with a long history of mining activities, yet very little is known about the heavy metal contamination in its surrounding environment. in this research work, ...

The revenue management concept and techniques are applied to model the coordination of supply chain elements. The fundamental premise of this approach is synchronization of a group of business entities consist-ing of a manufacturer and multiple suppliers to achieve an optimal supply chain capacity plans. The output of the supply chain can be various products and thus it is measured in terms of ...

in a recent paper in this journal, yang et al. [feng yang, dexiang wu,liang liang, gongbing bi & desheng dash wu (2009), supply chaindea:production possibility set and performance evaluation model] definedtwo types of supply chain production possibility set which were proved to beequivalent to each other. they also proposed a new model for evaluatingsupply chains. there are, however, some short...
