1) Identify 3 key stakeholders for each of the following decisions:

the design of a traffic light at a new intersection,

the design of a new oil drilling rig or platform,

the design of a new enterprise management system for a major company.

2) Briefly describe the purpose of each type of model: schematic, mathematical, and physical.

3) Read through problem 9.9 in the course textbook and review the table provided with that problem. Which concept would you choose to develop? Why? Is there any further work to do to make a decision? If so, what would you recommend?

To illustrate some important issues in conducting trade studies, consider the following simplified example. The trade study involved six alternative system concepts. Five MOEs were used, each weighted equally. For simplicity s sake, I have titled the MOEs A , B , C , D, and E. After assigning values to each MOE of the six alternatives, the results were the following:

Note that two stood out well above the rest, both receiving the same total number of points:

Weighted MOE	A	B	C	D	E	Total
Concept I	1	1	5	4	2	13
Concept II	3	3	2	5	4	17
Concept III	4	1	5	5	5	20
Concept IV	2	2	3	5	1	13
Concept V	4	4	4	4	4	20
Concept VI	1	1	1	3	3	9

On the basis of the above rating profiles,

(a) Would you conclude that concept III to be superior, equal, or inferior to concept V?

Explain your answer.

If you were not entirely satisfied with this result, what further information would you try to obtain?

Discuss potential opportunities for further study that might lead to a clearer recommendation between concepts III and V.

Please answer the above three questions
