Mr$.$ K$\text{'}$s is a very popular halr salon. It offers high$-$quality hairstyling and physical relaxation services at a reasonable price, so It always

has unlimited demand. The service process includes five activities that are conducted in the sequence described next $($the time

required for each activity is shown in parentheses$)$:

Actlvity $1$: Welcome a guest and offer homemade herb tea $(12$ minutes$).$

Actlvity $2$: Wash and condition hair $(12$ minutes$).$

Actlvity $3$: Neck, shoulder, and back stress$-$release massage $(12$ minutes$).$

Actlvity $4$: Design the halrstyle and do the halr $(30$ minutes$).$

Actlvity $5$ : Check out the guest $(8$ minutes$).$

Three servers $($S$1,$ S$2,$ and S$3)$ offer the services in a worker$-$paced line. The assignment of tasks to servers is the following: $S1$ does

Activity $1,$ S$2$ does actlvitles $2$ and $3,$ and $S3$ does actlvitles $4$ and $5.$

Instruction: Do not round your intermediate calculations. Round your final answers to $2$ decimal places.

a$.$ What is the labor content?

b$.$ What is the average labor utilization?

c$.$

At a wage rate of $$24$ per hour, what is the cost of direct labor

per customer?

Mr$.$ K considers hiring a new employee to help any one $($and

d$.$ only one$)$ of the servers without changing the tasks performed

by each server. What will be the new cost of direct labor?

Returning to the three$-$worker scenario, Mr$.$ K contemplates

e$.$

redesigning the assignment of tasks to servers. For this, Mr$.$

$K$ is evaluating the reassignment of Activity $5$ from $S3$ to $S1.$

What will be the new cost of direct labor?

Returning to the original question, Mr$.K$ is thinking to add one

f$.$ additional worker to the process. The worker would be

assigned to the same set of tasks

as one of the current workers. First, decide which set of tasks

would benefit from one additional worker, then calculate the

process capacity $($customers per hour$)?$

Returning to the original question, Suppose $4$ minutes of

g$.$

processing time from activity $4$ could be moved to activity $3$

while keeping the task assignments the same. What would be

the capacity of this new process $($customers per hour$)?$

Returning to the original question, Suppose each worker

h$.$

could be trained to complete all activities and they could all

work independently of each other. What would be the

capacity of this process $($customers per hour$)?$
