The problem chose for this decision making project is a question about what type of transportation would be best to use to get from Hillsboro, Gresham, Milwaukie and Tigard to Portland State University to be taken by students. The methodology that is used for this project is a Hierarchical Decision Model (HDM). The model used is abbreviated as (MOGSA) which stands for Mission, Objectives, Goals, Strategies, and Actions. A five decision criteria were used: Cost, Time, Safety, Comfort and Flexibility. These criteria were evaluated using a pairwise comparison method. Four transportation alternatives were considered for the project: Personal Car, Trimet Max, Bus and Taxi/Cab. To measure the judgments, a group of experts were lumped together to help compare and contrast the results from those who were measuring judgments according to the HDM mode. The group of experts composed of students who travel from Hillsboro, Gresham, Milwaukie and Tigard to Portland State University on a daily basis. The Inconsistency ranged from 0.01 to 0.03. The disagreement for the experts was 0.024. Even though some evaluators chose other options individually, the final results indicated that traveling with Trimet Max was the preferred method if evaluated using the criteria that were selected for the decision problem. The HDM proved to be useful in helping neutralize an individual preferences to make this complex decision. This method of decision making is recommended for any group of individuals with a complex decision to make.
