In all types of communication, the ability to share information is often hindered because the meaning of information can be drastically affected by the context in which it is viewed and interpreted. This is especially true among manufacturing simulation systems because of the growing complexity of manufacturing information and the increasing need to exchange this information not only among different simulation systems but also between simulation systems and systems that perform different functions (e.g., process planning, scheduling, etc.). Different manufacturing functions may use different terms to mean the exact same concept or use the exact same term to mean very different concepts. Often, the loosely defined natural language definitions associated with the terms contain much ambiguity that doesn't make these differences evident and/or do not provide enough information to resolve the differences. A solution to this problem is the development of a taxonomy, or ontology, of manufacturing concepts and terms along with their respective formal and unambiguous definitions. The Process Specification Language (PSL) (Version 1.0) developed at the National Institute of Standards and Technology identifies, formally defines,and structures the semantic concepts intrinsic to the capture and exchange of discrete manufacturing process information.
