A Virtual Cell Scheduling Algorithm

In this chapter, we begin by defining a new manufacturing concept termed Virtual Cellular Manufacturing System (VCMS). The VCMS is an expansion of the virtual cell concept proposed by McLean and all at the NIST AMRF in the early 1980’s [4].Then, we will show how the virtual cellular concept can be a provider of flexibility for factories of the future. A time-phased linear programming algorithm which has been developed especially for controlling VCMS will be presented. Finally, a simulation comparison between a VCMS and a Group Technology Cell has been performed. Results obtained from the simulations demonstrate the superiority of VCMS over the GT Cell System.
