Bus 3330: ASSEMBLY LINE BALANCING You have just been hired at the Suzuki motorcycle plant that assembles engines for their GSX-R series bikes. Because of its superior performance, demand for the GSX750 has been increasing at an exponential rate. Over the next year, you expect to have to assemble 120 engines/day. The engine assembly line works one eight hour shift/day. Assembling an engine consists of 17 tasks, see below. Task # Required Predecessor None + -at 55UJE.auw- Time (minutes) 0.5 0.6 0.4 3.6 0.2 0.5 0.4 1.25 0.4 0.4 1.25 0.4 2.3 3.5 1.3 2 3 4 None 6 7 8 10 13 14 6 10 11 9, 12 5 13, 14 15 16 0.7 16 17 1.8 Please prepare the following: a.) Draw the precedence diagram b.) Determine the cycle time c.) Determine the theoretical minimum number of workstations d.) Assuming tasks can't be divided, determine the most engines that can be assembled per eight hour day. (HINT: we didn't talk about this in class, try to use logic here) e.) Apply the assembly line balancing heuristic. Assign the longest task first. If there are ties, assign the task with the lowest # first (e.g. #1 assigned ahead of #6) f.) Calculate the efficiency of the solution you found in part e. g.) Did the heuristic work well in this problem? Why/Why not
