PDES/STEP: the cornerstone of CALS

Abstract

Computer-aided acquisition and logistics support (CALS) is a collection of standards for data exchange and a strategy for information sharing and integration. An information base that provides the complete, computer-sensible definition of the product to be designed, manufactured, and supported is the key element for CALS' success. Implementation of the Standard for the Exchange of Product Model Data (STEP) is recognized by government and industry in the US and Europe as the mechanism to achieve the CALS integrated weapon systems database. The purpose of the article is to provide a short overview of the Produce Data Exchange using STEP (PDES) effort and to highlight the importance of STEP to CALS.<>
