A Hybrid Genetic Algorithm/Simulation Approach for Redundancy Optimization with Objective of Maximizing Mean Lifetime and Considering Component Selection

H. Karimi; A.A. Najafi

Volume 2, Issue 2 , June 2013, , Pages 35-46

  In this paper, we consider a reliability redundancy optimization problem in a series-parallel type system employing the redundancy strategy of cold-standby. The problem consists of two parts component selection and determination of redundancy level of each component—which need to be solved so that ...  Read More

A Genetic Algorithm Coupled with Tabu Search for Bi-Objective Permutation Flow Shop

N. Shahsavari Pour; M.H. Abolhasani Ashkezari; H. Mohammadi Andargoli

Volume 2, Issue 1 , February 2013, , Pages 20-29

  Considering flow shop scheduling problem with more objectives, will help to make it more practical. For this purpose, we have intended both the makespan and total due date cost simultaneously. Total due date cost is included the sum of earliness and tardiness cost. In order to solve this problem, a genetic ...  Read More

A. Jafari; P. Chiniforooshan; F. Zabihi

Volume 2, Issue 1 , February 2013, , Pages 45-62

  This paper investigates the problem of designing an integrated production-distribution system which supports strategic and tactical decision levels in supply chain management. This overall optimization is achieved using mathematical programming for modeling the supply chain functions such as location, ...  Read More

Designing a Genetic Algorithm to Optimize Fulfilled Orders in Order Picking Planning Problem with Probabilistic Demand

M. Seyedrezaei; S.E. Najafi; A. Aghajani; H. Bagherzadeh Valami

Volume 1, Issue 2 , July 2012, , Pages 40-57

  Distribution centers (DCs) play an important key role in supply chain. Delivering the right items to the right customers at the right time, at the right cost is a critical mission of the DCs. Today, customer satisfaction is an important factor for supplier companies in order to gain more profits. Optimizing ...  Read More
