Assembly Line Balancing 4.16 The letters in the table below represent work elements in an assembly precedence diagram. (a) Construct the precedence diagram and (b) determine the total work content time. (c) Use the largest candidate rule to assign work elements to stations using a service time (T) of 1.5 min, and (d) compute the balance delay for your solution.

(a) Construct the precedence diagram for this job. (b) If the ideal cycle time is 1.1 min and the repositioning time is 0.1 min, what is the theoretical minimum number of workstations required to minimize the balance delay under the assumption that there will be one worker per station? (c) Using the largest candidate rule, assign work elements to stations. (d) Compute the balance delay for your solution. Work Element Immediate Predecessors 7.
