1. The purpose of the TEXTBOOK INVENTORY SYSTEM at a campus bookstore is to supply
textbooks to students for classes at a local university.
The university’s academic
departments submit initial data about courses, instructors, textbooks, and projected
enrollments to the bookstore on a TEXTBOOK MASTER LIST. The bookstore generates a
PURCHASE ORDER, which is sent to publishing companies supplying textbooks. Book
orders arrive at the bookstore accompanied by a PACKING SLIP, which is checked and
verified by the receiving department. Students fill out a BOOK REQUEST that includes
course information. When they pay for their books, the students are given a SALES
RECEIPT.

2. The purpose of the PLANT SCIENCE INFORMATION SYSTEM is to document the study
results from a wide variety of experiments performed on selected plants. A study is
initiated by a researcher who submits a RESEARCH PROPOSAL. After a panel review by a
group of scientists, the researcher is required to submit a RESEARCH PLAN AND
SCHEDULE. A FDA RESEARCH PERMIT REQUEST is sent to the Food and Drug
Administration, which sends back a RESEARCH PERMIT. As the experiment progresses,
the researcher fills out and submits EXPERIMENT NOTES. At the conclusion of the
project, the researcher’s results are reported on an EXPERIMENT HISTOGRAM.

3. The purpose of the production scheduling system is to respond to a PRODUCTION ORDER
(submitted by the SALES DEPARTMENT) by generating a daily PRODUCTION SCHEDULE,
generating RAW MATERIAL REQUISITIONS (sent to the MATERIALS MANAGEMENT
DEPARTMENT) for all production orders scheduled for the next day, and generating JOB
TICKETS for the work to be completed at each workstation during the next day (sent to the
SHOP FLOOR SHIFT SUPERVISOR). The work is described in the following statements.
The production scheduling problem can be conveniently broken down into three functions:
routing, loading, and releasing. For each product on a PRODUCTION ORDER, we must
determine which workstations are needed, in what sequence the work must be done, and
how much time should be necessary at each workstation to complete the work. This data
is available from the PRODUCTION ROUTE SHEETS. This process, which is referred to as
ROUTING THE ORDER, results in a ROUTE TICKET. Given a ROUTE TICKET (for a single
product on the original PRODUCTION ORDER), we then LOAD THE REQUEST. Loading is
nothing more than reserving dates and times at specific workstations. The reservations
that have already been made are recorded in the WORKSTATION LOAD SHEETS. Loading
requires us to look for the earliest available time slot for each task, being careful to preserve
the required sequence of tasks (determined from the ROUTE TICKET). At the end of each
day, the WORKSTATION LOAD SHEETS for each workstation are used to produce a
PRODUCTION SCHEDULE. JOB TICKETS are prepared for each task at each workstation.
The materials needed are determined from the BILL OF MATERIALS data store, and
MATERIAL REQUESTS are generated for appropriate quantities.
