Question
Problem 2: Every fall, volunteers administer flu vaccine shots at a local supermarket. The process involves the following four steps sequentially: Activity 1. reception 2. drug allergy consultation 3. Fill out form and sign waiver 4. Administer vaccination Average Time in Seconds 30 60 45 (a) What is the maximum number of people can be vaccinated per hour with four volunteers, ea (b) Which activity (c) With five volunteers, what would be the maximum capacity of the process, when there is no (d) With five volunteers, if only two of them can give vaccination, please draw a diagram of process responsible for one activity? How many more people can be vaccinated with the fifth volunteer? limitation on the volunteer's abilities? a fifth volunteer should be assigned to, in order to vaccinate more people per hour? design that can achieve the maximum capacity in part (c).Explanation / Answer
Answer to question a :
Average time in seconds is highest for activity 4 which therefore is the bottleneck. Since the process capacity is determined by the bottleneck activity, the overall process can handle 1 patient every 90 seconds
Therefore ,
Maximum number of people can be vaccinated per hour ( 3600 seconds ) = 3600 / 90 = 40
40 PEOPLE CAN BE VACCINATED PER HOUR
Answer to question b:
The fifth volunteer should be assigned to the bottleneck activity which is activity 5 :Administer vaccination in order to vaccinate more people per hour.
Effective processing time of activity 5 after adding one more volunteer = 90 / 2 = 45 seconds
Under such scenario, the new bottleneck activity becomes activity 2 with average time of 60 seconds. The number of people now can be vaccinated per hour = 3600 seconds / 60 seconds = 60 people
More number of people which can be vaccinated with the fifth volunteer = 60 people – 40 people = 20 people
20 more people can be vaccinated using the fifth volunteer
Answer to question c :
With 5 volunteers , maximum capacity of the process per hour = 3600 seconds / Average time of the bottleneck activity ( activity 2 ) = 3600 / 60 = 60
Answer to question d :
The relevant diagram to the process design with 2 volunteers administering vaccination as follows :
Reception
Drug allergy consultation
Fill out form and sign waiver
Administer Vaccination by volunteer
Administer vaccination by volunteer
40 PEOPLE CAN BE VACCINATED PER HOUR
