Purchasing a Used Car Using Multiple Criteria Decision Making
Edwards, Thomas G.; Chelst, Kenneth R.
Mathematics Teacher, v101 n2 p126-135 Sep 2007
When studying mathematics, students often ask the age-old question, "When will I ever use this in my future?" The activities described in this article demonstrate for students a process that brings the power of mathematical reasoning to bear on a difficult decision involving multiple criteria that is sure to resonate with the interests of many of them: choosing the right used car to purchase. This objective is met by introducing the concept of Multiple Criteria Decision Making (MCDM), as well as a structured method for identifying a best alternative in such situations. This lesson easily demonstrates the breadth of mathematics applications and possible avenues for non-traditional problem solving through mathematics. (Contains 9 tables.)
