Meta-Heuristic Algorithms for Two-Stage Assembly Flow Shop Scheduling Problem with Considering Setup Times of Machines

Mehdi Yazdani

Volume 18, Issue 58 , October 2020, , Pages 307-335


  This paper deals with the problem of two-stage assembly flow shop scheduling with considering sequence-independent setup times .The objective is to minimize totalcompletion times of all orders. In this problem, there are several orders for one type of product. Each ordered product is formed of several ...  Read More

A Mathematical Model for Operating Rooms Planning Under Uncertainty (The case: Ghaem Hospital of Mashhad)
Volume 17, Issue 52 , April 2019, , Pages 59-88


  . The control and planning of operating rooms have became more and more important for hospital managers. Nowadays, the operating rooms, as key resources, often lead to a great time waste. So, appropriate scheduling of operations in order to increase the efficiency of the operating rooms, are significant ...  Read More

Seyed Mohammad Taghi Fatemi Ghomi; Ehsan Arabzadeh; Behrooz Karimi

Volume 16, Issue 48 , April 2018, , Pages 1-30


  Home health care services have a key importance in modern societies. Most organizations working in this area in Iran use the traditional procedure to plan and manage medical staff and determine the arrangement of visiting patients. This procedure often increases costs and reduces the satisfaction of ...  Read More

Fuzzy multi-objective preventive maintenance and replacement scheduling using integer non-linear programming

Reza Alikhani; Mahmoud Saremi

Volume 14, Issue 43 , January 2017, , Pages 79-108


  The scheduling of preventive maintenance and replacement is one of the crucial issues in the literature of system reliability and maintenance engineering. The importance of this issue is more evident in series system in which by stopping a component the whole system will stop. However, the quest of the ...  Read More

Integrated Approach of Process Scheduling and Planning Based on Combining Fuzzy Knowledge Base and Meta Heuristic Method

Darush Mohamadi Zanjirani; Majid Esmailian; Saeedeh Jokar

Volume 14, Issue 43 , January 2017, , Pages 135-161


  Process planning involves determining the most suitable and efficient manufacturing (assembly) processes and their sequence in order to produce a product (part). These processes should be compatible with required attributes in product design documentation. Process planning and scheduling optimization ...  Read More

A hybrid meta-heuristic algorithm for dual resource constrained flexible job shop scheduling problem

Mehdi Yazdani; Mostafa Zandieh; Reza Tavakkoli-Moghaddam

Volume 12, Issue 33 , July 2015, , Pages 43-74

       In this paper, the dual-resource constrained flexible job-shop scheduling problem (DRCFJSP) with objective of minimizing the makespan is investigated. Under studied problem is NP-hard and mainly includes three sub-problems. The first one is to assign each operation to a machine out ...  Read More
