Answer C
Mr. K’s is a very popular hair salon. It offers high quality hairstyling andphysical relaxation services at a reasonable price, so it always has unlimiteddemand. The service process includes five activities that are conducted inthe sequence described below ( the time required for each activity is shownin parenthesis):Activity 1: Welcome a guest and offer homemade herb tea (10 minutes)Activity 2: Wash and condition har (10 minutes)Activity 3: Neck, shoulder, and back stress release massage (10 minutes)Activity 4: Design and hair style and do the hair (25 minutes)Activity 5: Ring up the guest bill (5 minutes)Each activity has one employee dedicated to it. For the following questions,assume unlimited demand. Also assume that the employee at activity 1 onlyadmits new guests at the rate of the bottleneck.(a) Which resource is the bottleneck?(b) What is the capacity of the process?(c) What is the flow rate?(d) What is the utilization of the employee at activity 3(e) What is the cycle time?

The time in the welding operation is spent as follows: 2 hours waiting in front of the cutting machine for the batch to start, 2 hours waiting for the setupof the machine, 1 hour waiting for the other pieces of the batch to go through cutting, 1 minute at the cutting machine, and 3 hours waiting for the transfer to the welding machine. Then, at the welding machine, the unit spends 1 hour waiting in front of the welding machine for the batch to start, 1 hour waiting for the setup of the welding machine, 0.5 hour waiting for the other pieces of the batch to go through welding, 0.5 minute at the welding machine, and 1 hour waiting for the transfer to the next department.

One line will mean a fixed cost of $6,000 a month, and two lines will mean a fixed cost of $10,500 a month. Each line would be able to process 15 cars an hour. Variable costs will be $3 per car, and revenue will be $5.95 per car. The manager projects an average demand of between 14 and 18 cars anhour. Would you recommend one or two lines?

During an 8 hour day 40 lorries arrive and it takes the team 10 minutes to unload each lorry. Each team member is paid RM3 per hour and it costs RM10 per hour to keep lorries waiting. Studies show that increasing the team to 14 men would reduce the unloading time to 7 minutes. Would it be worthwhile increasing the team to 14?arrow_forward
