Real-Time Order Tracking For Supply Systems With Multiple Transportation Stages, Nana Bryan
Doctoral Dissertations
This dissertation studies a supply system consisting of a retailer, a manufacturer, and multiple transportation stages. The manufacturer fulfills the demand from the retailer for a single product. The replenishment process is not instantaneous. Orders may take more than one time period to be shipped from the manufacturer’s location, and shipped orders pass through multiple transportation stages until they reach the retailer. Each stage may represent a physical location or a step in the delivery process. Shipments are not allowed to cross over in time.

This paper presents an analysis of the parameters used in a multi-state model for permanent health insurance (PHI). The model is a simplification of that used in the United Kingdom. To avoid using duration dependent probabilities, the model splits the sick state into several sub-states to act as a proxy for duration spent in a particular state. This enables a Markov approach to be adopted. Lapses are incorporated within the model, and the net premium for a particular policy is tested for sensitivity to the various parameters used, including their interaction with the lapse rate. One of our conclusions is …
