Problem 22S-18 (Algo)

A steel product is manufactured by starting with raw material (carbon steel wire) and then processing it sequentially through five operations using machines A to E, respectively (see table below). This is the only use that the five machines are put to. The hourly rates for each machine are given in the table. Answer the following questions. Use the original output rates to answer each question (i.e., disregard any changes mentioned in previous questions).

Operation:	1	2	3	4	5
Machine:	A	B	C	D	E
Hourly unit output rate:	100	90	80	70	60

Consider the following questions.

a. What is the maximum output per hour of the steel product?

Maximum output per hour______ products

b. By how much would the output be improved if the output of B was increased to 100?

By____ products

c. By how much would the output be improved if the output for C was increased to 90?

By____ products

d. By how much would the output be improved if the output for C was increased to 100?

By____ products

e. What is the effect on the system if machine A can only manage an output of 50 in one hour?

We lose ____ products

f. What is the effect on the system if machine C can only manage an output of 40 in one hour?

We lose ____ products

g. What is the effect on the system if machine B is allowed to drop to an output of 80 in one hour?

We lose ____ products
