The Computation and Research Evaluation System (CARES) III Analyzer was used to evaluate the proposal. The input data consisted of samples of 1H and 1R Cognizance (Cog) items. The criteria for evaluation were Total Variable Cost and Average Days Delay. Since the Navy inputes shortage cost from desired performance and budget levels, the relevant Total Variable Cost is the sum of procurement order cost and holding cost. Supply Material Availability was held constant at 85%. Additional cost projections were obtained concerning the implementation of a variable shortage cost.

These policies included reimbursement at a rate of 2% over cost to hospitals. During the same decade, the concept of prospective payment was first articulated in a scholarly journal. This concept would pay a pre-calculated reimbursement based on categories of diagnoses: in essence, a budget for hospital services. By 1983, sufficient momentum had developed to fundamentally change payment policy at the national level, by implementing a prospective payment system for inpatient procedures. Depending on the effect of the incentives in play, this change in payment policy could influence whether some admissions are done on an inpatient or an outpatient basis. This study models admission type as a binary dependent variable in a difference-in-difference framework to assess the effect of the policy change for a collection of diagnoses. The primary data sets used in this paper are the State Inpatient Database (SID) and the State Ambulatory Surgery Database (SASD) from the state of New Jersey (1998-1999 and 2002-2003). The analysis supports the conclusions that (1) OPPS did not reduce the conditional probability of outpatient admission, (2) in a limited number of cases may have increased this probability, and (3) combining these two conclusions, support the conclusion that OPPS in fact did have a net positive impact on the movement toward outpatient admission

This paper provides a graduated perspective, which, while including technical discussion, places cost analysis in a larger strategic context. The graduated perspective takes us from the broad perspective of appreciating the military threat expressed in the cold war, recognizing the need for short term force structure and readiness despite longer development lead-times; then it narrows the focus through some of the policy, procedural, and analytical tools implementing modern cost analysis. The intention is to provide a survey with a coherent view across different historical contexts and technical disciplines. This view will answer the questions “What is the historical and technical environment in which defense system cost analysis is practiced?” and “How does this environment impose conditions on the practice of cost analysis?”.
