A small electrical appliance is to be assembled on a single model assembly line. The line will be operated 250 days/year, 15 hours/day. The work content has been divided into work elements as defined in the following Table. Also given are the element times and precedence requirements. Annual production is to be 200,000 units. Repositioning time for each worker is 0.08 min. Determine (a) average hourly production rate, (b) cycle time, and (c) theoretical minimum number of workers required to meet annual production requirements. (d) Use all the line balancing algorithm (Largest Candidate Rule, Kilbridge and Wester Method, and Ranked Positional Weights Method) to balance the line. For your solution, determine (e) balance efficiency of the line.

![A small electrical appliance is to be assembled on a single model assembly line. The
line will be operated 250 days/year, 15 hours/day. The work content has been divided
into work elements as defined in the following Table. Also given are the element times
and precedence requirements. Annual production is to be 200,000 units. Repositioning
time for each worker is 0.08 min. Determine (a) average hourly production rate, (b)
cycle time, and (c) theoretical minimum number of workers required to meet annual
production requirements. (d) Use all the line balancing algorithm (Largest Candidate
Rule, Kilbridge and Wester Method, and Ranked Positional Weights Method) to
balance the line. For your solution, determine (e) balance efficiency of the line.
