In this paper, we study a logistics problem arising in military transport planning. A military organization operates a large fleet of vehicles in a depot to serve the requests of various operational units. Each request has a fixed start and end time, and is served by a prescribed number of vehicles. We address the following two problems: (1) how many vehicles are at least needed to meet a given service level of requests; and (2) suppose we allow each request to shift its start time by a constant duration, call all the requests be met? A Niche genetic algorithm, together ...

In an effort to improve students' problem solving skills with information technology across the industrial engineering curriculum, we created an Internet based problem-solving environment. The module implemented for engineering economy presents a realistic problem that establishes connections with other courses. The design of the learning environment promotes metacognitive skill development by requiring students to explain each major problem solving action taken and to evaluate their own progress toward a solution. Experience in two successive semesters of a large introductory course indicates that information technology can be used effectively to create opportunities for students to collaboratively solve realistic engineering problems, thereby ...
