HW #6 (Project & Learning Curve) Due on 5/31 (Wednesday)

(Prob. 18)

“Assume the network and data that follow: “

(Prob. 4)

“You have just completed a pilot run of 10 units of a major product and found the processing time for each unit was as follows:

(Prob. 7)

“Johnson Industries received a contract to develop and produce four high-intensity long-distance receiver/transmitters for cellular phones. The first took 2,000 labor hours …………”

(Prob. 8)

“Lambda Computer Products competed for and won a contract to produce two prototype units of a new type of computer ………..” (Note that learning effects occur on both labor and materials).

(a) (Same as in the copy)

(b) (The part (b) should be replaced by the following. Use method 2 for forgetting effect)

“Suppose that Lambda was asked to present a bid for additional 10 units after 3 months delay since the second unit was completed. During this time, personnel and equipment were reassigned to other projects. What would be the total production costs for the additional 10 units?” ( When you consider the forgetting effects for this problem, make sure that the PRODUCTION UNIT has to be an integer, i.e., if you get any non-integer values from the equation, it needs to be rounded to the nearest integer value.)

(Example 6)

From the lecture notes on page 11. Use method 2 for computing the forgetting effect.
