This paper considers the joint supplier selection, replenishment and manufacturing control problem in a dynamic stochastic context. This problem is characterized by conflicting interests between suppliers, the manufacturer, and clients, which raise the need for coordination and information sharing. This paper contributes to the discourse mainly by developing and resolving an integrated mathemat...

the relationship between the manufacturer and supplier has changed from one of competition into that of greater cooperation during recent years. the selection and evaluation of suppliers are primary and important issues when an enterprise implements supplier relationship management (srm) and total quality management (tqm). much research indicates that most enterprises tend to evaluate their sup...

Prochymosin is one of the most important aspartic proteinases used as a milk-clotting enzyme in cheese production. In the present investigation we report sequence of cDNA encoding goat ( Capra hircus ) preprochymosin and compare its nucleotide and deduced amino acid sequences with sequences of other ruminants preprochymosin. As bovine prochymosin, the caprine prochymosin cDNA encodes 365 amino ...

In many industries such as automotive industry, there are a lot of suppliers dealing with the final products manufacturer. With growing numbers of suppliers, the suppliers’ efficiency measurement often becomes the most significant concern for manufacturers. Therefore, various performance measurement models such as DEA, AHP, TOPSIS, are developed to support supplier selection decisions. After an...

This study aims at reducing energy consumption in supply chain networks by providing optimal integrated production and transportation scheduling. The considered consists of one main manufacturing center, multiple units (i.e., suppliers), heterogeneous vehicles as the fleet. To schedule this complex network an energy-efficient way, several decisions should be made concerning assignment orders to...

In order to achieve stable and sustainable systems for recycling post-consumer goods, frequently it is necessary to concentrate the flows from many collection points of suppliers to meet the volume requirements for the recycler. The collection network must be grown over time to maximize the collection volume while keeping costs as low as possible. This paper addresses a complex and interconnect...

this study aims to minimize the total cost of a four-echelon supply chain including suppliers, an assembler, distributers, and retailers. the total cost consists of purchasing raw materials from the suppliers by the assembler, assembling the final product, materials transportation from the suppliers to the assembler, product transportation from the assembler to the distributors, product transpo...

Twelve batches of commercially available foetal bovine sera were tested for the presence of bovine viral diarrhoea virus (BVDV) and BDVD antibodies. The antibodies were found in three batches coming from two suppliers. Fragments of BVDV genome were present in five of these batches when tested by RT-PCR. All of them were type 1 BVDV according to a direct sequencing of PCR products. However, the ...
