THE CNA OFFICER PROJECTION MODEL, VOL I GUIDE FOR USERS
Published Date: June 1, 1974
The Officer Projection Model (OPM) projects the flow of officers through the ranks of the U.S. Navy. It projects an initial officer inventory (characterized by length of service, grade, and promotion status) in yearly increments, accounting for attrition, promotion, legal constraints (Title 10 of the U.S. Code), and such management policies as minimum accession requirements and end strength targets. It is devoted especially to simulating the Navy's officer promotion system, and provides several options which consider the interactions of flow point, promotion rate, zone size, grade structure and end strength, and early and late selection. The OPM will also compute annual compensation, separation pay, retirement pay, and the present value of retirement pay for the remaining life expectancy of projected retirees. The model provides management with a tool for evaluating alternative promotion policies and retirement proposals, and for studying the interactions of officer end strengths, promotions, and accessions, and the cost of changes in longevity and grade structure. The Guide for Users, Volume I, describes the Navy's officer system and the model and discusses the data and policy variables to be specified by the user. The Guide for Programmers, Volume II, provides a detailed explanation of the computer coding as an aid to changing, and making special adaptations of the model.
