Modeling of Maintenance Operations

Setup times optimization with considering maintenance scheduling by using nonlinear modeling

The present paper, titled “optimizing the time of preparation, taking into account the timing of   repair and maintenance using non-linear modeling”, has been implemented with the aim of designing and presenting a mathematical model to get the best sequence of operations leading to minimum the total time of production. The main research question is related to the reduction of time and productio...

Modeling the Hybrid Flow Shop Scheduling Problem Followed by an Assembly Stage Considering Aging Effects and Preventive Maintenance Activities

Scheduling problem for the hybrid flow shop scheduling problem (HFSP) followed by an assembly stage considering aging effects additional preventive and maintenance activities is studied in this paper. In this production system, a number of products of different kinds are produced. Each product is assembled with a set of several parts. The first stage is a hybrid flow shop to produce parts. All ...

A fixed and flexible maintenance operations planning optimization in a parallel batch machines manufacturing system

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 equipments...

Modelling and solving the job shop scheduling Problem followed by an assembly stage considering maintenance operations and access restrictions to machines

This paper considers job shop scheduling problem followed by an assembly stage and Lot Streaming (LS). It is supposed here that a number of products have been ordered to be produced. Each product is assembled with a set of several parts. The production system includes two stages. The first stage is a job shop to produce parts. Each machine can process only one part at the same time. The second ...
