Analysis of Computer Modeling Parameters for USAF CONUS Cargo Movement Strategy

摘要

This analysis provides a foundation upon which to build a model of the Air Force CONUS freight shipment network. The general findings were that a model is possible, but attention must be given to that data which is collected for input to the model; that some of the simplifying assumptions about shipping costs would induce significant error into a final model; USAF Logistic Airlift (LOGAIR) costs compete favorably with common carrier charges for similar service response; and virtually no model is commercially available that could be easily adapted for use in modelling this system. The data collected by HQ AFLC is not complete when compared to independent Traffic Management Workload Reporting and Productivity System (T-WRAPS) report. The categories of variables adequately describe each shipment, although the usefulness of the inputs would improve with detailed hazardous material coding and distance to be shipped. Collection of CONUS cargo movement data should be integrated with standardized shipment documentation and reporting procedures for all Air Force cargo. This study used the accumulated data base to view the specific frequency distributions for weight, volume, number of pieces in a shipment, and priority for three separate populations: all shipments, Transportation Priority 1 shipments, and Mission Capable (MICAP) shipments. The study analyzed cost behavior and computed LOGAIR costs in cents per pound based on all LOGAIR cargo moved, actual air eligible LOGAIR cargo moved, and only actual air priority LOGAIR cargo.
