Question

A service process shown above serves two types of customers Type-1 customers must go through the A-B-C-D-H process route while Type-2 customers must go through the A-B-E-F-G-H process route. The service time for each step is shown below Step A, 7 minutes per customer Step B, 9 minutes per customer Stop C, 18.7 inutes per cus ner Step D, 14.8 minutes per cu omer Step E, 17.5 inutes per cu tomer Step F. 13.1 minutes per customer Step G, 11.5 minutes per customer Step H, 8 minutes per customer The process operates 11 hours per day If 58% of th customers the Type-1 customers and the rest are e Type-2 c stomers, what s the average capacity per day for the service process The average process capacity is customers per day

Explanation / Answer

Through the process flow-

One Type-1 customer would take (A+B+C+D+H) = 57.5 minutes

One Type-2 customer would take (A+B+E+F+G+H) = 66.1 minutes

Out of 11 hours, 58% of customers are Type-1, hence for 6.38 hours (58% of 11 hours) Type-1 customers arrive and for 4.62 hours(42% of 11 hours) Type-2 customers arrive

Condition1 - If one type-1 customer takes 57.5 min, then in 6.38 hours, 6 customers will arrive

Condition2 - If one type-2 customer takes 66.1 min, then in 4.62 hours, 4 customers will arrive

Hence,

Average Process Capacity= 6+4

= 10 Customers per day
