In recent years, upgrading manufacturing informatization has put forward higher requirements for the designer. The traditional design method requires designers to switch their thinking on platform of multiple dimensions, which increases difficulty. With development virtual reality technology, process in a 3D environment can be realized. Aiming at conceptual stage process, this paper carries out...

In this paper, a new mathematical model for the problem of job scheduling in virtual manufacturing cells (VMC) is presented to minimizing the completion time of all jobs. Sequence dependent setup times of machines is considered and lot-streaming is possible. In Virtual manufacturing cells, each job has a different processing path and there is a set of machines for processing each operation. The...
