This paper deals with the cyclic flow shop robotic cell scheduling problem with multiple single and dual gripper robots, in which multiple part types are processed on multiple machines successively with free, time-windows and no-wait pickup criteria. The robots execute the transportation of parts between the machines. A novel comprehensive mixed-integer linear programming model has been propose...

web 2.0 is not a single technology or standard but rather a set of concepts and features. web 2.0 concepts and features call for further attention. since, previous studies have only addressed only some of these concepts and features. in order to give a comprehensive view of web 2.0, these features are collected through literature review and a framework of web 2.0 features is presented. also, du...

Efficient and on-time maintenance plays a crucial role inreducing cost and increasing the market share of an industrial unit. Preventivemaintenance is a broad term that encompasses a set of activitiesaimed at improving the overall reliability and availability of a systembefore machinery breakdown. The previous studies have addressed thescheduling of preventive maintenance. These studies have co...

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...

Railway scheduling is a complex task of rail operators that involves the generation of a conflict-free train timetable. This paper presents a discrete-event simulation-based optimization approach for solving the train timetabling problem to minimize total weighted unplanned stop time in a hybrid single and double track railway networks. The designed simulation model is used as a platform for ge...
