Problem 1. A precedence table is given below for a process with 5 tasks, their immediate predecessors their task times: Task Immediate Task time label predecessor(s) (minutes) 2.0 A 3.0 1.5 B.C 1.0 ED 1.6 3.2 1.2 GH 2.4 1 F. 2 .2 1.8 1111 2.5 Workers are known to work 8 hours in one shift, and there are 2 shifts per day dedicated to this job. The daily output need is 320 pieces. a) Plot a simple precedence diagram for the process, with activities on the nodes. b) Calculate the positional weight of each task. c) Calculate the minimum cycle time (CT min), the maximum cycle time (CTmax) and the estimated cycle time (CT). d) Calculate the theoretical minimum number of workstations. Nomin e) Assign tasks to work stations in order of most following tasks (the tiebreaker is the greatest task time) using the following table. Calculate the idle time for each workstation and for the whole process. The company is using a linear process layout. Calculate the percentage of idle time (balance delay) for the line: g) Compute the efficiency of the line
