The assembly line process for a manufacturing company requires the completion of eight tasks to assemble one unit of a product. The table below shows the task numbers, task times, and precede tasks. The diagram below show the precedent relationships for the eight tasks. The company CEO set a target throughput rate of 400 units per day. The company’s factory design plan calls for the assembly line to operate 7.2 hours a day for five days a week.
