The Decision Making Model for Ming's Dinner

Decision Tree

After a long period programming language skill training, I am used to this kind of logical thinking when I need to make decision. The decision tree is a good way when you have multiple choices and complicated decision-making case;  under each decision you can still dig further and make more detail decision. Among each branch of decision, you can give different weight value to the decision. Combine and calculate all the weight value of each node (event), it will gives you a suggested result.

This case is an example for me to choose what dinner I will have each day.  It first comes that I need to decide whether I will eat outside or cook at home. The influence factors (D1) probably will depend on my budget, weather, time, mood and so on. If I choose to eat outside, then I need to decide what kind of restaurant I prefer. The influence factors (D2) probably will depend on the location of the restaurant or the taste of the food. If I choose to cook by myself, then I need to decide what type of dinner I will cook. The influence factors (D3) probably will be the time limit, food resource, and courage.

Ming's Logical Flow

IF (WEATHER is good) and (Budget is enough)

     THEN

              IF (Time is enough)

                   IF (Taste driven)

                        Chinese Restaurant

                    ELSE

                        Mexican Restaurant

              ELSE

                      IF (Taste Driven)

                           TACO BELL

                       ELSE

                            KFC

     ELSE

             IF (TIME is enough) and (Food Resource is enough)

                  experiment from FoodNetwork

            ELSE

                   IF (Taste Driven)

                         Instant Noodle

                   ELSE

                          Frozen Pizza

A Process and Model I get from the Internet

Resource: http://www.tea.state.tx.us/resources/ssced/instass/15.htm

1. Near the roots of the Decision Tree, write the occasion for the decision, such as resolving a conflict.

2. On the main trunk and branches of the tree,  identify one or more alternative decisions.

3. In the leaves and stems above, list the positive and negative consequences of each alternative.

4. Weighing the consequences, write the decision in the box at the top of the tree.
