(c) A flexible machining system consists of load/unload station and two
machining work stations. Station 1 is the load/unload station. Station
2 performs milling operations and consists of two servers (two
identical CNC milling machines). Station 3 has one server that
performs drilling (one CNC drill press). The stations are connected by
a part handling system that has four work carriers. The mean transport
time is 3.0 min. the FMS produces two parts, A and B. the part mix
fractions and process routings for the two parts presented in the table
below. The operation frequency fijk= 1.0 for all operations. Determine
(a) maximum production rate of FMS, (b) corresponding production
rates of each product, (c) utilization of each station and, (d) number
of busy servers at each station.
