Flexible manufacturing system (FMS) enhances the firm's flexibility and responsiveness to the ever-changing customer demand by providing a fast product diversification capability. Performance of an FMS is highly dependent upon the accuracy of scheduling policy for the components of the system, such as automated guided vehicles (AGVs). An AGV as a mobile robot provides remarkable industrial capa...

scheduling has become an attractive area for artificial intelligence researchers. on other hand, in today's real-world manufacturing systems, the importance of an efficient maintenance schedule program cannot be ignored because it plays an important role in the success of manufacturing facilities. a maintenance program may be considered as the heath care of manufacturing machines and equip...

A methodology is presented for the dynamic scheduling of flexible manufacturing systems (FMSs). A two-level control hierarchy is suggested. The higher level is used for determining a dominant decision criterion and relevant scheduling rules, based on an analysis of the actual shop status. The lower level uses simulation for determining the best scheduling policy to be selected. Simulation is us...

The manufacturing environment these days is characterised by rapid change, posing new challenges and problems to the production and operations manager in the industry. Under this circumstances, process flexibility is fast becoming a major priority for many organisations as they attempt to deal with these changes. In response to the need for process flexibility, increasing attention is being giv...

tendency to optimization in last decades has resulted in creating multi-product manufacturing systems. production planning in such systems is difficult, because optimal production volume that is calculated must be consistent with limitation of production system. hence, integration has been proposed to decide about these problems concurrently. main problem in integration is how we can relate pro...

This paper exploits the interactions between the machine scheduling and the scheduling of Material Handling System in a given Flexible Manufacturing System (FMS) layout with an objective of minimization of makespan and to study the overall feasibility of generation of optimal simultaneous schedules. A heuristic scheduling algorithm is developed which takes into account both machine and vehicle ...

Flexible manufacturing systems (FMS) require efficient scheduling strategies to achieve their principal advantage of being able to combine high flexibility with high productivity. This paper presents a novel constraint programming (CP) formulation addressing the FMS scheduling problem for systems that work under the operational policy of part movement. The formulation addresses some critical fe...

In practical manufacturing settings it is often possible to obtain, in real-time, information about the operation of several machines in a flexible manufacturing system (FMS) that can be quite useful in scheduling part flows. In this brief paper the authors introduce some scheduling policies that can effectively utilize such information (something the policies in [1] do not do) and they provide...

This paper presents a novel scheduling of resource-constrained Flexible Manufacturing System (FMS) with consideration the following sub-problems: (i) machine loading and unloading, (ii) manufacturing operation scheduling, (iii) assignment, (iv) Automated Guided Vehicle (AGV) scheduling. In proposed model, both AGV machinery are considered as required resources. Energy efficiency AGVs has been s...

Competitiveness and rapid expansion of flexible manufacturing system (FMS) as one of the industrial alternatives has attracted many practitioners’ and academicians’ interest. Recent globalization events have further encouraged FMS development into distributed, self-reliant units of production center. The flexible manufacturing system in distributed system (FMSDS) considers multi-factory environ...
