Penultimate Support Systems makes fairly good speaker and equipment support stands for music groups. The assembly process involves two operations: (1) fabrication, or cutting aluminum tubing to the correct lengths, and (2) assembly, with purchased fasteners and injection-molded plastic parts. Set-up time for assembly is negligible. Fabrication set-up time and run-time per unit, assembly run-time per unit, and the production schedule for next week follow. Organize the work to minimize makespan (the time it takes to complete the product) and idle time, and create a Gantt chart. Can this work be accomplished in two 40-hour shifts? At Penultimate, it is normal practice to complete lots in one process before sending them to a following process.
