The following process has to be designed to produce 720 units over an 8-hour production shift by combining tasks into work stations using line balancing analysis. The following table & precedence diagram provides the processing times and sequence relationships for all tasks in the process: Task Processing Time (seconds) 20 15 12 B D 18 B C D E F G E 20 12 15 15 F H a. Answer the following questions Determine the cycle time in seconds) required to produce 720 units over an 8-hour shift (4 marks). b. What is the theoretical minimum number of workstations required? (4 marks) c. Develop a balanced process using the largest number of followers heuristic (using the longest processing time to break ties); indicate which tasks will be grouped into workstations and show the complete analysis used to develop a balanced process using this heuristic (8 marks) d. Based on your analysis in part (c), determine the total % of idle time and the efficiency for the process you developed (4 marks)
