several plans, and eventually the one shown in Figure $1$ was accepted by the management team.

The assemble plan will run two shifts per day. Each shift will operate for $8$ hours.

The expected demand rate is $30$ fans per day.

Figure $1$

Based on the information given in the case, answer the following questions. Show all work that you need to arrive at your answers.

a$)$ Develop the activity precedence diagram.

b$)$ Determine the minimum cycle time, the maximum cycle time.

c$)$ What will be the production rate per day if minimum cycle time is used? maximum cycle time is used?

d$)$ In order to meet the projected demand what should be the cycle time?

$3$

e$)$ What is the theoretical number of minimum workstations?

f$)$ Assign work elements according to the most following tasks rule.

g$)$ Assign work elements according to the greatest positional weight rule.

h$)$ Assign work elements according to the shortest processing time rule.

i$)$ Calculate the percentage idle time and assembly line efficiency for each of the above three rules.

j$)$ Which assembly line do you recommend? Why?
