The estimation of production rate (or throughput) is important in manufacturing system design. Herein, we consider the an automotive body shop which two types car are produced, and one (engine car) substituted by other (electric gradually. In this shop, different underbody lines installed because structures cars differ completely; however, side line main shared cars. Furthermore, assume that re...

We consider the movement minimization problem in a conveyor flow shop processing controlled by one worker for all machines. A machine can only execute tasks if the worker is present. Each machine can serve as a buffer. The worker has to cover a certain distance to move from one machine to the other. The distance between two machines Pp and Pq is jp qj. The objective is to minimize the total dis...

The traditional simplified drum buffer rope (SDBR) does not consider the application of re-entrant flow shop (RFS) in a random environment which might involve variable processing times and machine breakdowns. This paper proposed a weighted layer production buffer and weighted production buffer to monitor the status of the buffer deviation when applying SDBR in a RFS with non-deterministic param...
