Operations Researchers Design Program to Get Ambulances On the Scene Faster

November 1, 2009

Operations researchers created a computer program to help more effectively disperse emergency response vehicles across a coverage area. The researchers are considering many factors in their development, including geographical layout, real-time locations of ambulances and historical trends as well as the types and frequency of calls. An underlying concept of the program assumes the ambulances remain on the road, where they can be more efficient, instead of coming back to the hub after each call. Ultimately, the program will indicate the optimum locations to station deployed ambulances.

WHAT IS DYNAMIC PROGRAMMING? Essentially, dynamic programming is the process of taking a complex problem and breaking it into simpler steps. One of the most important steps in this research was to figure out what is called the value function (the way to measure a single decision's impact on what happens afterward). For ambulance placement, the researchers attempted to find out the most effective places to station emergency vehicles so that they can best serve the anticipated needs of the community.

ABOUT COMPUTER MODELING: Computer modeling is used to simulate the structure and appearance of both static objects, such as building architecture, and dynamic situations, such as a football game. Computer models can enable the user to test the consequences of choices and decisions. They can provide cutaway views that let you see aspects of an object that would be invisible in the real artifact, as well as visualization tools that can provide many different perspectives. Physical models that reproduce behavior are limited by the physics of the world, while computer models have much looser bounds. Computer models enable you to run companies and civilizations, fight battles, play football games and evolve new species.
