The success of a supply chain is highly dependent on selection of best suppliers. These decisions are an important component of production and logistics management for many firms. Little attention is given in the literature to the simultaneous consideration of cardinal and ordinal data in supplier selection process. This paper proposes a new integrated data envelopment analysis (DEA) model whic...

Economic firms interact via suppliers/customers interactions. These interactions define a production network. We here study the dynamics of these networks under very simple assumptions and show that they exhibit noticeable patterns of wealth and production. The main dynamical properties of this time/space organisation are studied and shown to be shared by a wide class of models. keywords: netwo...

In today’s accelerating world economy, the drive to continually cut costs and focus on core competencies has driven many to outsource some or all of their production. In this environment, improving supply chain execution and leveraging the supply base through effective supplier relationship management (SRM) has become more critical than ever in achieving competitive advantage. It was found that...

Vendor performance plays a key role in price, quality, timely delivery and service in achieving the goals of the supply chain. Given this, today's supplier performance has become a critical element in the success or failure of a company. In this study, an idealized planning model with multi-criteria decision-making approach with network analysis tool based on the expansion of fuzzy quality func...

The supply chain of a manufacturing enterprise is a world-wide network of suppliers, factories, warehouses, distribution centres and retailers through which raw materials are acquired, transformed and delivered to customers. Supply chain management is the strategic, tactical and operational level decision making that optimizes supply chain performance. The strategic level defines the supply cha...

This paper traces the diffusion of " just-in-time " production in the Japanese automotive sector, as reflected by inventory reductions in a sample of 52 suppliers and assemblers. We show that most inventory reductions occurred during a remarkable burst of activity starting in the late 1960s. Companies affiliated with Toyota were the early adopters but were followed very quickly by others in Jap...

Procter & Gamble put into practice CombineNet’s approach to building sourcing networks, called expressive competition. At its heart is a vision that looks past lowest-price reverse auctions and combinatorial package bidding toward a highly expressive commerce relationship with suppliers. It enables suppliers to make electronic offers that express rich forms of capabilities and efficiencies. As ...

Background: Vascular endothelial growth factor (VEGF) has a key role in angiogene-sis and in transplantation. The level of VEGF is related to the differences in the DNA sequence of its promoter region. Objectives: In this study, the association between the combination of VEGF –1154 G and –2578 C alleles and VEGF production by LPS-stimulated PBMCs was investigated. In addition; the relationship ...
