Decision Theory

Decisions

There are many types of decision making

1.      Decision making under uncertainty

It refer to situations where more than one outcome can result from any single decision

2.      Decision making under certainty

Whenever there exists only one outcome for a decision we are dealing along with this category for example linear programming, transportation sequencing and assignment and so on.

3.      Decision making by using prior data

This occurs whenever it is possible to employ past experience or prior data to develop probabilities for the happened of each data

4.      Decision making with no prior data

No past experience exists that can be utilized to derive outcome probabilities in this case the decision maker uses her or his subjective estimates of probabilities for different outcomes
