Evaluation of the USTRANSCOM Deployment Analysis Prototype (DAP)
Abstract
This report provides an overview and concept evaluation of the Deployment Analysis Prototype (DAP). Section 1 considers the DAP in the context of the deployment planning environment. Section 2 provides an overview and evaluation of the DAP structures as well as specific algorithmic, and interface issues. Sections 2 and 3 also provide recommendations for improvement of the DAP. The fundamental approximations made in the MODES model assumed continuous transportation. While this allowed the entire problem to be captured in an optimization model, there were serious difficulties interpreting the results for the very small deployments used in testing. This seems unavoidable when the model is used in a batch environment (as opposed to an interactive environment). The major problem with MODES occurs in small deployments when the results do not translate into whole ship loads. While there are other options which might be considered (e.g., multi-commodity flow models), it seems apparent that all tractable optimization models, in order to simultaneously consider both air and sea and the scheduling of assets on legs and the scheduling of movement requirements on the assets, would require the assumption of continuous transportation and hence would suffer from the same problem.
