Replacer is a knowledge system that provides a consistent means for developing plans for rail replacement. It was developed, tested, and evaluated in cooperation with Burlington Northern Railroad. BN officials found that it has substantial potential for improving rail replacement planning. When compared to a network optimization decision model, Replacer was found to produce essentially the same plans while using a more flexible and understandable methodology.
