For the following the question, assume unlimited demand. Also assume the employee at activity 1 only admits new guest at the rate of the battleneck. 1. Draw a process flow disgram (o grophical way to describe the process) 2. What rescurce is the bottleneck? 3. What is the capacity of the process? 4. What is the flow rate? 5. What is the cycle time?

The process flow diagram as follows :
Welcome a guest and offer homemade herb tea ( 10 minutes)
Wash and condition air ( 10 minutes)
Neck , shoulder and back stress release massage ( 10 minutes)
Design the hairstyle and do the hair ( 20 minutes )
Ring up the guest bill ( 5 minutes)
The bottleneck resource is the one which has the maximum processing time. In the given case, Design the hairstyle and do the air has the maximum processing time of 20 minutes and hence is the Bottleneck resource.
Capacity of the process is determined by processing time of the bottleneck process. Therefore , the process can handle = 60 minutes/ 20 minutes = 3 customers per hour
Flow rate is defined as minimum of demand and process capacity . Since it is mentioned that “employee at activity 1 only admits new guest at the rate of bottleneck”. In the given case , Capacity of the process = demand.
Therefore , Flow rate of the process = Process capacity = 20 minutes / customer
Cycle time is the The period required to complete one cycle of an operation; or to complete a function, job, or task from start to finish. Cycle time is used in differentiating total duration of a process from its run time.
Thus, Cycle time in this case ( sum of time of 5 activities)
= 10 + 10 + 10 + 20 + 5
= 55 minutes
Welcome a guest and offer homemade herb tea ( 10 minutes)
Wash and condition air ( 10 minutes)
Neck , shoulder and back stress release massage ( 10 minutes)
Design the hairstyle and do the hair ( 20 minutes )
Ring up the guest bill ( 5 minutes)
