An assembly line is to operate eight hours per day with a desired output of 240 units per day. The following precedence diagram contains information on this product’s task times and precedence relationships. What is the efficiency of your line balance, assuming it is running at the cycle time from part (a)? Determine the theoretical minimum number of workstations required (the actual number may be greater). 60 60

Question d) The idle time for the assembly line per cycle = _____ minute(s) The Mach 10 is a one-person sailboat manufactured by Creative Leisure. The final assembly plant is in Cupertino, California. The assembly area is available for production of the Mach 10 for 200 minutes per day. (The rest of the time it is busy making other products.) The daily demand is 60 boats. Given the following information: Task Predecessors Performance Time (mins) 2. 1 1 A B...
Francis Johnson's plant needs to design an efficient assembly line to make a new product. The assembly line needs to produce 12 units per hour, and there is room for only five workstations. The tasks and the order in which they must be performed are shown in the following table. Tasks cannot be split, and it would be too expensive to duplicate any task. TASK TIME IMMEDIATE TASK (MINUTES) PREDECESSOR 2.5 2.0 2.0 3.0 3.0 3.0 3.0 A,B, C b....
