the use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach

abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...

Coordinated and Joint Ordering Policies for Two Commodity Inventory System

Queueing Inventory System in a Two-level Supply Chain with One-for-One Ordering Policy

Consider a two-level inventory system consisting of one supplier and one retailer. The retailer faces a Poisson demand with a known rate and applies base stock (one-for-one ordering) policy. That is, his inventory position is set to a pre-determined level, so the demand pattern is transferred exactly to the supplier. The supplier has an inventory system and a service unit with exponentially dis...

A Queueing-Inventory System with Repair Center for Defective Items and One-for-One Ordering Policy

In this paper we consider a system consisting of a supplier with a single processing unit, a repair center, and a retailer with Poisson demand. We assume that the retailer applies one-for-one ordering policy with backorders for his inventory control. The retailer’s orders form a queue in the supplier processing unit. We also assume that a certain fraction of the products produced by the supplie...

A hybrid decision making system using DEA and fuzzy models for supplier selection in the presence of multiple decision makers

Using Fuzzy Relational Models for Control

In this paper the use of Fuzzy Relational Models (FRMs) for model-based process control is investigated. The work presented here is centred around the development of a Fuzzy Internal Model Controller (FIMC) for a simulated multi-variable pH process. The paper begins with a brief introduction which sets the scene for the work. There then follows a description of the pH process and the particular...
