this research provides an optimization tool for use by supply chain managers in the design and operation of manufacturing- distribution networks under uncertain demand conditions. the problem under consideration consists of determining the supply chain infrastructure; raw material purchases, shipments, and inventories; and finished product production quantities, inventories, and shipments neede...

Western-European consumers have become not only more demanding on product availability in retail outlets but also on other food attributes such as quality, integrity, and safety. When (re)designing f ood supply-chain networks, from a logistics point of view, one has to consider these demands next to traditional efficiency and responsiveness requirements. The concept ‘quality controlled logistic...

University bookstores have a complex multi-product, multi-supplier supply chain with complex channel relationships such as product substitution, random yields, reverse logistics and returns, and risk sharing contracts. Supply chain efficiency is important to the bookstore due to low overall profit margin. The used book buyback activity is an example of reverse logistics with random yield with s...

Throughout product lifecycle, the definition of product data is confronted to the diversity of the business activities and influenced by their specific information systems. This paper is related to the analysis of technical and functional product data exchange solutions throughout product lifecycle. In such context, the communication between partners is ensured by setting agreements, methodolog...

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 explains a model for analyzing and measuring the propagation of order amplifications (i.e. bullwhip effect) for a single-product supply network topology considering exogenous uncertainty and linear and time-invariant inventory management policies for network entities. the stream of orders placed by each entity of the network is characterized assuming customer demand is ergodic. in fa...

in this paper, a two-echelon supply chain, which includes two products based on the following considerations, has been studied and the bullwhip effect is quantified. providing a measure for bullwhip effect that enables us to analyze and reduce this phenomenon in supply chains with two products is the basic purpose of this paper. demand of products is presented by the first order vector autoregr...

We investigate here antecedents and consequences of supplier integration (black-box and gray-box) in product development activities. Antecedents include embeddedness with suppliers, supply base rationalization, and supplier selection based on product development capabilities. Product innovation and quality are modeled as returns of supplier integration in product development. We also assess the...

This paper examines the opportunities and challenges facing the pharmaceutical industry in moving to a primarily "continuous processing"-based supply chain. The current predominantly "large batch" and centralized manufacturing system designed for the "blockbuster" drug has driven a slow-paced, inventory heavy operating model that is increasingly regarded as inflexible and unsustainable. Indeed,...

Supply chain management (SCM) is not always concerned with optimal solutions conventionally in terms of product allocation. Virtual market based supply chain operation solves the product allocation problem by distributing the scheduled resources based on the agent interactions in the market. We formulate supply chain model as a discrete resource allocation problem under dynamic environment, and...
