Given the part mix, process routings, and processing times for the three parts in Problem 16.1. The FMS planned for this part family will operate 250 day/yr and the anticipated availability of the system is 90%. Determine how many servers at each station will be required to achieve an annual production rate of 40,000 parts/yr if (a) the FMS operates 8 hr/day, (b) 16 hr/day, and (c) 24 hr/day. (d) Which system configuration is preferred, and why?

Problem 16.1

A flexible manufacturing cell consists of two machining workstations plus a load/unload station. The load/unload station is station I. Station 2 performs milling operations and consists of one server (one CNC milling machine). Station 3 has one server that performs drilling (one CNC drill press). The three stations are connected by a part handling system that has one work carrier. The mean transport time is 2.5 min. The FMC produces three parts. A, B, and C. The part mix fractions and process routings for the three parts arc presented in the table below. The operation frequency fijk = 1.0 for all operations. Determine: (a) maximum production rate of the FMC, (b) corresponding production rates of each product, (c) utilization of each machine in the system, and (d) number of busy servers at each station.
