Today’s Electronics specializes in manufacturing modern electronic components. It also builds the equipment that produces the components. Phyllis Weinberger, who is responsible for advising the president of Today’s Electronics on electronic manufacturing equipment, has developed the following table concerning a proposed facility:
a. Develop an opportunity loss table.
b. What is the minimax regret decision?
Use .7 alpha for Hurwicz

Opportunity Loss Table

Strong Market | Fair Market | Poor Market | Maximum | |
Large Facility |

19000 | 310000 | 310000 |
Medium Size Facility | 250000 | 0 | 100000 | 250000 |
Small Facility | 350000 | 29000 | 32000 | 350000 |
No Facility | 550000 | 129000 | 0 | 550000 |
b)
Minimax decision approach:
Minimum of Maximum (Opportunity Loss table) is 250000 for Medium size facility.
So decision would be to open a Medium size facility.
Though none of the above question uses Hurwcz apporach. value of alpha is given. So we will calculate weighted average by Hirwich approach too.
By using Hurwicz approach we can calculate the weighted average
as
And choose the decision variable which has maximum weight.
Strong Market | Fair Market | Poor Market | Weighted Average | |
Large Facility | 5,50,000 | 1,10,000 | -3,10,000 | 292000 |
Medium Size Facility | 3,00,000 | 1,29,000 | -1,00,000 | 180000 |
Small Facility | 2,00,000 | 1,00,000 | -32,000 | 130400 |
No Facility | 0 | 0 | 0 | 0 |
As Max(Weighted Average)=292000, the best decision by Hurwicz approach would be to set up a Large Facility
