MODELING OF A MULTI-STAGE TRANSPORTATION SYSTEM

Multi-Objective Scheduling Problem in a Three-Stage Production System

A three stage production system is considered in this paper. There are two stages to fabricate and ready the parts and an assembly stage to assembly the parts and complete the products in this system. Suppose that a number of products of different kinds are ordered. Each product is assembled with a set of several parts. At first the parts are produced in the first stage with parallel machines a...

Modeling a Multi-period Transportation System for Supplier Selection and Orders Allocation Problem (case study: Parchsaz company)

The combination of transportation costs is very important in supplier decisions. In these days economic and productive firms in order to gain a competitive advantage or competitive advantage with the aim of gaining more market share in terms of controlling the cost of raw materials that directly and indirectly constitutes a major part of the cost of the product They are on their agenda. Hence, ...

Modeling and solving a three-stage fixed charge transportation problem considering stochastic demand and price

This paper considers a three-stage fixed charge transportation problem regarding stochastic demand and price. The objective of the problem is to maximize the profit for supplying demands. Three kinds of costs are presented here: variable costs that are related to amount of transportation cost between a source and a destination. Fixed charge exists whenever there is a transfer from a source to a...

Selvaraj: Simulation Modeling of Single Line Multi Stage Manufacturing System

Present study compares performance of proposed model [Hybrid Extended Kanban Control System (HEKCS)], with Extended Kanban Control System (EKCS) and Constant Work In Process (CONWIP) in a single line and multi stage manufacturing system with or without effect of machine breakdown. It was observed that, when demand rate increases, throughput, average WIP and utilization% also gradually increases...
