Abstract
This thesis addresses growing concerns about work-in-process (WIP), or backlogs, of small purchase actions at Navy field contracting organizations. Managers of these organizations need an analytical tool to predict if the average age and numbers of contract actions in WIP are increasing. This tool can help management determine if action is necessary to maintain customer service. This thesis develops a two step decision rule to help managers predict whether WIP is getting larger and older, indicating a need for management action. Management tools and models are reviewed for applicability to the WIP problem. Regression analysis, inventory models, and queueing theory are examined as possible tools for forecasting levels of WIP. After concluding that these tools are not applicable, a two step decision rule is designed to predict: (1) the number of purchase requests in WIP and (2) whether the average age of the requests is increasing.
