1. Multi-objective scheduling and assembly line balancing with resource constraint and cost uncertainty: A “box” set robust optimization

Javad Behnamian; Zeynab Rahami

Volume 7, Issue 1 , Winter and Spring 2020, , Pages 220-232


  Assembly lines are flow-oriented production systems that are of great importance in the industrial production of standard, high-volume products and even more recently, they have become commonplace in producing low-volume custom products. The main goal of designers of these lines is to increase the efficiency ...  Read More

Volume 4, Issue 2 , Summer and Autumn 2017, , Pages 35-51


  This paper includes a simulation model built in order to predict the performance indicessuch aswaiting time by analyzing queue’s components in the real world under uncertain and subjective situation. The objective of this paper is to predict the waiting time of each customer in an M/M/C queuing ...  Read More

3. Coordination of green supply chain network, considering uncertain demand and stochastic CO2 emission level

H. Golpira; M. Zandieh; E. Najafi; S. Sadi Nezhade

Volume 2, Issue 2 , Summer and Autumn 2015, , Pages 43-54

  Many supply chain problems involve optimization of various conflicting objectives. This paper formulates a green supply chain network throughout a two-stage mixed integer linear problem with uncertain demand and stochastic environmental respects level. The first objective function of the proposed model ...  Read More
