The role of medicines in health systems is increasing day by day. medicine supply chain a part the system that if not properly addressed, concept community unlikely to experience significant growth. To fill gaps and available challenging network (MSCN), present paper, efforts have been made propose location-production-distribution-transportation-inventory holding problem for multi-echelon multi...

according to the current state of water resources and the increasing demand for water, the supply of future needs will be faced with serious constraints. on the one hand, the failure to supply sometimes causes social and political problems. on the other hand, improper exploitation of water resources will lead to irreparable damages. therefore, the use of optimization models for the planning of ...

In this paper a new approach is presented to solve multi-objective production scheduling and rescheduling problems. Furthermore the relationship between production goals and heuristic solving methods in an extended flexible flow shop environment is also investigated. We define production goals by specifying objective functions and apply special production constraints for the extended flow shop ...

optimization of cutting conditions is a non-linear optimization with constraint and it is very important to the increase of productivity and the reduction of costs. in recent years, several evolutionary and meta-heuristic optimization algorithms were introduced. the cuckoo optimization algorithm (coa) is one of several recent and powerful meta-heuristics which is inspired by the cuckoos and the...

In this study, a bi-objective multi-state redundancy allocation problem of series-parallel systems consisting of some serial subsystems, each with non-repairable components in parallel, is investigated. Furthermore, due to uncertainty involved, both the performance rates and the availabilities of components are considered fuzzy. In addition, two strategies of all-unit and incremental-quantity d...

This article presents a comprehensive review of chaos embedded meta-heuristic optimization algorithms and describes the evolution of this algorithms along with some improvements, their combination with various methods as well as their applications. The reported results indicate that chaos embedded algorithms may handle engineering design problems efficiently in terms of precision and convergenc...
