An Optimization of Multi-product Assembly Lines Using Simulation and Multi-Objective Programming Approach

maedeh mosayeb motlagh; Parham Azimi; maghsoud Amiri

Volume 21, Issue 68 , May 2023, , Pages 75-120


  This paper investigates unreliable multi-product assembly lines with mixed (serial-parallel) layout model in which machines failures and repairing probabilities are considered. The aim of this study is to develop a multi-objective mathematical model consisting the maximization of the throughput rate ...  Read More

Proposed a Hybrid Multi-Objective competitive Algorithm for solving the redundancy allocation reliability problem

Roozbeh . Azizmohammadi; Maghsoud .Amiri; Reza Tavakkoli- Moghadam; Hamid Reza. Mashatzadegan

Volume 14, Issue 42 , October 2016, , Pages 103-121

  A redundancy allocation problem is a well-known NP-hard problem thatinvolves the selection of elements and redundancy levels to maximize thesystem reliability under various system-level constraints. In many practicaldesign situations, reliability apportionment is complicated because of thepresence of ...  Read More

A New Hybrid Method for Redundancy Allocation in Production Systems using Modified NSGA-II and MOPSO Algorithm

Ali Mohtashami*

Volume 12, Issue 33 , July 2015, , Pages 97-124

  This paper presents a multi-objective mathematical model for redundancy allocation in production systems. In many of the production and assembly lines, process times, time between failures and repaired times are generally distributed. The proposed method of this paper is able to consider time dependent ...  Read More

The Estimation of the Bullwhip Effect and Stock Functions Using Response Surface Methodology

maghsoud amiri; laya olfat; amir hasanzadeh

Volume 11, Issue 29 , July 2013, , Pages 89-112

  A major cause of supply chain deficiencies is the bullwhip effect. This phenomenon refers to demand variability increases as one move up the supply chain. Supply chain managers experience this variance amplification in both inventory levels and orders. Other side, dampening variability in orders may ...  Read More
