1. Ant colony optimization, genetic algorithm and hybrid metaheuristics: A new solution for parallel machines scheduling with sequence-dependent set-up times

Mahdi Nakhaeinejad

Volume 7, Issue 2 , Summer and Autumn 2020, , Pages 223-239


  The parallel machine scheduling problem (PMSP) is one of the most difficult classes of problem. Due to the complexity of the problem, obtaining optimal solution for the problems with large size is very time consuming and sometimes, computationally infeasible. So, heuristic algorithms that provide near-optimal ...  Read More

2. Simulation based optimization of multi-product supply chain under a JIT system

Arman Sajedinejad; Erfan Hassannayebi; Mohammad Saviz Asadi Lari

Volume 7, Issue 1 , Winter and Spring 2020, , Pages 87-106


   It is scientifically challenging to determine the inventory level all through the supply chain in such a way that the desired objectives such as effectiveness and responsiveness of the supply chain system can be obtained. Simulation is a means for solving various problems which cannot be solved ...  Read More

3. Partial inspection problem with double sampling designs in multi-stage systems considering cost uncertainty

Taha-Hossein Hejazi; Pardis Roozkhosh

Volume 6, Issue 1 , Winter and Spring 2019, , Pages 1-17


  The nature of input materials is changed as long as the product reaches the consumer in many types of manufacturing processes. In designing and improving multi-stage systems, the study of the steps separately may not lead to the greatest possible improvement in the whole system, therefore the study of ...  Read More

4. A realistic perish ability inventory management for location-inventory-routing problem based on Genetic Algorithm

Mohammad Bagher Fakhrzad; Zahra Alidoosti

Volume 5, Issue 1 , Winter and Spring 2018, , Pages 106-121


  In this paper, it was an attempt to be present a practical perishability inventory model. The proposed model adds using spoilage of products and variable prices within a time period to a recently published location-inventory-routing model in order to make it more realistic. Aforementioned model by integration ...  Read More
