SITUATION: A company is about to begin
production of a new product. The manager of
the department that will produce one of the
components for the product wants to know
how often the machine used to produce the
item will be available for other work. The
machine will produce the item at a rate of
200 units a day. Eighty units will be used daily
in assembling the final product. Assembly will
take place five days a week, 50 weeks a year.
The manager estimates that it will take almost
a full day to get the machine ready for a
production run, at the cost of $300. Inventory
holding costs will be $10 a year.
QUESTION: Suppose the manager decides to
increase the run size of the new product. How
many additional units would be needed just
to accommodate the other job? How much
will that increase the total annual cost?
Explain why process selection is essential in system design.
The Mach 10 is a one-person sailboat manufactured by Creative Leisure. The final assembly plant is in Cupertino, California. The assembly area is available for production of theMach 10 for 200 minutes per day. (The rest of the time it is busy making other products.) The daily demand is 60 boats. Given the information in the table on the next page,a) Draw the precedence diagram and assign tasks using five workstations .b) What is the efficiency of the assembly line, using your answer to (a)?c) What is the theoretical minimum number of workstations?d) What is the idle time per boat produced?
