In this article, we propose a new methodology for solving the vendor selection and the supply quotas determination problem. The proposed methodology combines the Analytic Hierarchy Process (AHP) for determining the coefficients of the objective functions and a new multiple objective programming method based on the cooperative game theory for vendor selection and supply quotas determination. The...

This paper investigates the impacts of both the demand uncertainty and the supply disruption probability on the decisions of two sourcing strategies: one is dual sourcing and the other is single sourcing with contingent supply. The expected profit functions and the optimal decisions of the buyer are derived and compared. Then sensitivity analysis is given through numerical examples. Explicit in...

Electronic markets in recent decades contribute remarkably in business transactions. Many organizations consider traditional ways of trade non-economical and therefore they do trade only through electronic markets. There are different categorizations of electronic markets functions. In one classification, functions of electronic markets are categorized into classes as information, transactions,...

Empirical studies of international trade have concentrated on singleequation models to analyse the demand relationship for imports and exports [Houthakker and Magee (1969). Naqvi et al (1983), Bnhmani-Oskooee (1984,1986)]. These studies have assumed that the imports and exports price elasticities facing any individual country are infinite or at least large. The assumption of infinite supply pri...

A supply chain is a network of suppliers, factories, warehouses, distribution centers and retailers, through which raw materials are acquired, transformed, produced and delivered to the customer. A supply chain management system (SCMS) manages the cooperation of these system components. In the computational world, roles of individual entities in a supply chain can be implemented as distinct age...

Aiming at single mode of Underpan generator power supply, and the feature being not meet regular work system under special working conditions, engine fuel exhaustion, unexpected faults, Design Dual Mode Power Supply Distribution Circuit With Detection And Control Functions which includes Battery power, distribution module, anti-diode, detection underpan on-off control anti-loss module was propo...

The paper presents commonly used methodology for assessing damage of water supply networks after a seismic event. relies on deriving and applying so-called vulnerability function. An overview the existing functions is given together with parameters, primarily related to soil deformations, which are influencing assessment. Also, critical review possibility their use given. Finally, by using two ...

In supply chain networks, the flow of material occurs between various business entities such as suppliers, manufactures, distributors and retailers, which can be considered as the various echelons (levels) in a multi-echelon supply chain network. Spare parts supply chain management deals with optimizing stocking, purchasing, repairing and disposing activities of purchased parts and their compon...

Supply chain management is an integrative approach for planning and control of materials and information flows with suppliers and customers as well as between different functions within a company. One particularly important element in supply chain management is the management of inventories. This field has received considerable attention during the last years. Nevertheless, most quantitative an...
