(Use the same scenario as above.) If the company produces 8 units of A and 5 units of B, the amount of slack (in hours) for process 1 isa. 14 hoursb. 20 hoursc. 57 hoursd. 23 hours. USE THIS SCENARIO FOR THE NEXT FIVE QUESTIONS.A company produces product A and product B. Each product must go through two processes. In the following "A" is used to represent the number ofunits of A to produce and "B" is used to represent the number units of B to produce. Each A produced requires five hours in process 1 and four hours inprocess 2. Each B produced requires four hours in process 1 and five hours in process 2. There are 80 hours of capacity available each week forprocess 1 and 100 hours available for process 2. Each A produced generates $6.00 in profit for the company. Each B produced generates $9.00 in profitfor the company. The company's objective function is to maximize

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?
4. Citizens of a country send documents to renew their passport. The average time in the mail is about 2 days. It takes 4 days before a clerk process them for 10 minutes and pass it to the next clerk.
