Solving an Integrated Cell Formation, Group Layout and Routing Problem Using Dynamic Programming Based Metaheuristic Algorithms

Mohammad Mohammadi; Kamran Forghani

Volume 16, Issue 49 , July 2018, , Pages 67-104


  The cell formation problem and the group layout problem, both are two important problems in designing a cellular manufacturing system. The cell formation problem is consist of grouping parts into part families and machines into production cells. In addition, the group layout problem is to find the arrangement ...  Read More

Designing Mathematical Model for Examinations Timetable in Universities and its Solutions Analysis

Hossein Shams Shemirani1; Mahdi Bashiri; Mohammad Modarres

Volume 15, Issue 44 , April 2017, , Pages 27-50


  In this research, optimization of examinations' timetable for university courses, based on a real problem in one of the universities in Iran is studied. The objective function defined for this problem is more practical and realistic than the other objective functions that have been utilized by previous ...  Read More

No-wait hybrid flowshop scheduling: models and solotion algorithms

Bahman Naderi

Volume 14, Issue 43 , January 2017, , Pages 53-77


  In this paper hybrid flowshop scheduling problem where some jobs, not all, have to follow no-wait restriction (that is, the operations of that job must be processed with no stop) is examined. In the literature, all papers assume that all jobs of the shops have to follow no-wait restrictions. First, this ...  Read More

A hybrid meta-heuristic algorithm for dual resource constrained flexible job shop scheduling problem

Mehdi Yazdani; Mostafa Zandieh; Reza Tavakkoli-Moghaddam

Volume 12, Issue 33 , July 2015, , Pages 43-74

       In this paper, the dual-resource constrained flexible job-shop scheduling problem (DRCFJSP) with objective of minimizing the makespan is investigated. Under studied problem is NP-hard and mainly includes three sub-problems. The first one is to assign each operation to a machine out ...  Read More

An Integrated Mathematical Model for Solving Dynamic Cell Formation Problem Considering Operator Assignment, Inter-cell and Intra-cell Layouts and Solving by Simulated Annealing

Esmaeil Mehdizadeh; Vahid Rahimi

Volume 13, Issue 37 , July 2015, , Pages 123-159

  Abstract This paper presents a mathematical model for solving dynamic cell formation problem, operator assignment and the inter-cellular and intra-cellular layouts simultaneously. The proposed model includes three objectives, the first objective seeks to minimize inter and intra-cell part movement, ...  Read More
