(b) If the ideal cycle time is 1.5 min and the repositioning time is 0.3 min, what is the theoretical minimum number of workstations required to minimize the balance delay under the assumption that there will be three workers per station? (c) Using ranked positional weights method, assign work elements to stations. Assume T = 10 min. (d) Compute the balance delay for your solution EN
