Problem
You have been asked to personally recommend a new travel agency to handle all airfare, accommodation, and related travel needs for your organization of 500 staff. One of your colleagues, who is responsible for the company's economic planning, suggests that the best travel agent could be selected mathematically by inputting the relevant factors for each agency and the weight (importance) of each factor. What decision making approach is your colleague recommending? Is this recommendation a good idea in this situation? Why or why not?
