Integrated Location-Allocation and Scheduling Model
, M.Sc. Thesis Sharif University of Technology ; Modarres Yazdi, Mohammad (Supervisor)
Abstract
Location-allocation problem is known as one of the classical problems in industrial engineering. The goals of these problems are finding optimal location of facilities and assigning these facilities to service demands from a given set of point. Location-allocation decisions are widespread through all organization in the world concerning private and public businesses. Therefore, in this study, a practical mathematical model is formulated and solved.In this paper we present a new approach for a budgeted constraint capacitated location-allocation problem integrated with cellular layout approach containing cell formation and group scheduling. Main decisions are composed of formation of...
The Inter-cell Layout Problem in Cellular Manufacturing Systems and Detecting the Optimal Number of Automated Guided Vehicles (AGVs)
, M.Sc. Thesis Sharif University of Technology ; Ghasemi Tari, Farhad (Supervisor)
Abstract
In this research, we present a new method for solving layout problems in the cellular manufacturing system. We also analyze the transportation systems using automated guided vehicles (AGVs) and its cost affecting the performance of cellular manufacturing system. For elimination of inter current and traffic problems, we use a new idea of dividing workstations to some non-overlapping closed zones to which independent automated guided vehicles (AGVs) are allocated for internal transfers in each zone. In this research, a combinational mathematical model has been developed for minimizing the cost of material flow intra and inter-loops and minimization of procurement of AGVs for each zone while...
