oPERATION MANAGEMENT
7. The local university has developed an eight-step process
for screening the thousands of admissions applications it
gets each year. The provost has decided that the best way
to take a first cut at all these applications is by employing
a line process. The following table shows the times and
predecessors for the various tasks:

a. (**) Draw a precedence diagram for the tasks. Suppose
the university needs to process 30 applications an hour
during the peak season. What is the takt time? What
is the theoretical minimum number of workstations?
b. (**) Develop workstation assignments by using the
"largest eligible task" rule.
c. (**) How many workstations does your solution
require? What is the cycle time for the line? What is the
idle time? What are the percent idle time and the effi-
ciency delay?
d. (***) In theory, what is the fastest cycle time possible,
given the tasks…

- Develop an event process chain (EPC) diagram for the following staff-recruiting process at Yellow Brook Photography: • The current recruitment process for Yellow Brook Photography takes approximately 90 days. It begins when a manager completes a requisition and sends it to the Human Resources Department. The Human Resources Department reviews and assigns a number to the requisition and returns it to the manager for approval. He or she approves it, obtains the required approval signatures, and then returns it to Human Resources. • Next, Human Resources creates a job posting and announces the position internally through the company’s intranet, bulletin boards, or a binder of current job openings. Human Resources collects responses internally for eight days. After that, Human Resources solicits résumés from external sources by advertising in newspapers and online.
