Given the work element times shown in the following table, what is the theoretical minimum number of workstations? Round your answer UP to the nearest whole number. Work Element Time (Sec) Immediate Predecessor(s) A 29 None B 43 A C 17 A D 36 B E 29 B F 33 C G 28 C H 25 D, E I 45 F, G J 49 H, Set up a table, with columns titled "Workstations", "Candidates", "Choice", "Cumulative Time", and "Idle Time". Assign work elements into workstations, one element at a time using the longest-work-element-time rule, while keeping an eye on the "idle time" and the precedence relationships in the diagram.
