1. Virtual manufacturing cells scheduling considering lotstreaming and sequence dependent setup times

A. Ayooq; A. Alem Tabriz; A. Javani

Volume 2, Issue 1 , Winter and Spring 2015, , Pages 61-73

Abstract
  In this paper, a new mathematical model for the problem of job scheduling in virtual manufacturing cells (VMC) is presented to minimizing the completion time of all jobs. Sequence dependent setup times of machines is considered and lot-streaming is possible. In Virtual manufacturing cells, ...  Read More

Behrouz Khorshidvand; Ashkan Ayough; Akbar Alem Tabriz

Volume 1, Issue 1 , Summer and Autumn 2014, , Pages 72-82

Abstract
  In this article, two different systems subject to shocks occurring based on a non-homogeneous Poisson process (NHPP) are analyzed. Type –I system is consisted of a single unit and type –II system is consisted of two parallel units in which both units operate identically and simultaneously. ...  Read More
