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

Developing (r,Q) & (R,T) inventory control models

Magsud Amiri; , Mohammad Amin Nayebi; Oveis Zarabadipour

Volume 12, Issue 33 , July 2015, Pages 125-124

  In this paper we have developed inventory control models (r,Q) & (R,T) in multi-items environment by two objectives as minimizing costs (holding & shortage) and risk level under four constraints. These constraints include: available budge, service level, storage space & allowed shortage quantities. ...  Read More
