This p aper presents a mathematical model and simulated annealing heuristics for assigning activities to workspaces and resources (e.g., equipment, parts, and toolboxes) to work/storage spaces during planned outages at electric power plants. These assignments are made such that the distance resources (toolboxes) travel throughout the duration of the outage(More)
The MoDOT Tracker performance measure " Number of Rail Passengers " is directly correlated with the level of passenger train delays. Therefore, the objective of this study was to develop a prioritized list of rail enhancements that addresses current passenger and freight rail performance on the Union Pacific line from St. Louis to Kansas City in order to(More)
(USDOT/OST-R). The mission of the UTC program is to advance U.S. technology and expertise in the many disciplines comprising transportation through the mechanisms of education, research, and technology transfer at university-based centers of excellence. Iowa State University, through its Institute for Transportation (InTrans), is the MTC lead institution.(More)

At The Boeing Company, stock levels for maintenance spares with substantial lead times must be established before fielding new aircraft designs. Initial calculations use mean time between demand estimates developed by the engineering department. After sufficient operating hours, stock levels are recalculated using statistical forecasts of maintenance(More)
16. Abstract The objective of this project was to develop fleet location, route decision, material selection, and treatment procedures for winter snow removal operations to improve MoDOT's services and lower costs. This work uses a systematic, heuristic-based optimization approach to integrate the winter road maintenance planning decisions, which is(More)

A three-tier logistics/production model is developed that addresses the integration of suppliers, manufacturers and distribution. The model can be applied at either micro (within facility) or macro (between facilities) levels. The multi-echelon problem is formulated to minimize overall inventory and setup cost. A simulated annealing based heuristic is(More)
