job shop scheduling problem has significant importance in many researchingfields such as production management and programming and also combinedoptimizing. job shop scheduling problem includes two sub-problems: machineassignment and sequence operation performing. in this paper combination ofparticle swarm optimization algorithm (pso) and gravitational search algorithm(gsa) have been presented f...

making a rational decision about the free production capacity of a firm requires accurate and comprehensive information in different fields such as unscheduled time of the machines, materials or other required resources status in the firm and the related supply chain. in this study, we try to achieve the needed information through integrating advanced available-to-promise mechanism with schedul...

this study investigates the coordination of production scheduling and maintenance planning in theflow shop scheduling environment. the problem is considered in a bi-objective form, minimizing themakespan as the production scheduling criterion and minimizing the system unavailability as themaintenance planning criterion. the time interval between consecutive maintenance activities as well as the...

“Planning and Scheduling in Manufacturing and Services” written by Michael L. Pinedo and published in the Springer Series in Operations Research is a recent book intended for a senior level or master level course on planning and scheduling either in an engineering or a business school. The book consists of four parts. Part I introduces the main features of scheduling models in manufacturing and...

nowadays, scheduling problems have a considerable application in production and service systems. in this paper, we consider the scheduling of n jobs on a single machine assuming no machine idleness, non-preemptive jobs and equal process times. in many of previous researches, because of the delivery dalays and holding costs, earliness and tardiness penalties emerge in the form of linear combinat...

this paper presented a mixed integer programming for integrated scheduling and process planning. the presented process plan included some orders with precedence relations similar to multiple traveling salesman problem (mtsp), which was categorized as an np-hard problem. these types of problems are also called advanced planning because of simultaneously determining the appropriate sequence and m...

scheduling for job shop is very important in both fields of production management and combinatorial op-timization. however, it is quite difficult to achieve an optimal solution to this problem with traditional opti-mization approaches owing to the high computational complexity. the combination of several optimization criteria induces additional complexity and new problems. in this paper, we pro...

Globalized production has become a new trend in the current competitive business environment, especially for the multinational companies in pursuit of lower cost, shorter time-to-market and better quality. For years, much emphasis has been focused on the concurrent design and manufacturing, and other integrated production activities. However, the distributed production scheduling, a post-design...
