Decision makers clearly change the criteria and the weighting of criteria as a function of their environments. In an article in ORMS Today, Totten and Tohamy describe logistics support systems which facilitate efficient routing of trucks and their cargoes for large firms. In it they describe systems which can learn how to weight the various corporate objectives as they change around the year. For example, around the holidays, the driver “get-home request” has the top priority. In contrast, during the remainder of the year, customer requirements have top priority. Hence, the system needs to be able to change the models used to facilitate decision making easily. With this change in priority comes the creation of new alternatives, such as load swapping, for the decision maker to consider. |
