IDEF2 Simulation Model Design

The third IDEF (IDEF2) was originally intended as a user interface modeling method. However, since the [node:1369] Program needed a simulation modeling tool, the resulting IDEF2 was a method for representing the time varying behavior of resources in a manufacturing system, providing a framework for specification of math model based simulations. It was the intent of the methodology program within ICAM to rectify this situation but limitation of funding did not allow this to happen. As a result, the lack of a method which would support the structuring of descriptions of the user view of a system has been a major shortcoming of the IDEF system. The basic problem from a methodology point of view is the need to distinguish between a description of what a system (existing or proposed) is supposed to do and a representative simulation model that will predict what a system will do. The latter was the focus of IDEF2, the former is the focus of IDEF3.

Integrated Computer-Aided Manufacturing (ICAM)

Body

From Wikipedia: Integrated Computer-Aided Manufacturing:

Integrated Computer-Aided Manufacturing (ICAM) is a US Air Force program to develop tools, techniques, and processes to support manufacturing integration and has influenced the computer-integrated manufacturing (CIM) and computer-aided manufacturing (CAM) project efforts of many companies.

The ICAM program was founded in 1976 and initiative managed by the US Air Force at Wright-Patterson as a part of their technology modernization efforts. The program initiated the development a series of standard for modeling and analysis in management and business improvement, called Integrated Definitions, short IDEFs.

Raytheon

Body

From Wikipedia: Raytheon:

Raytheon Company is a major American defense contractor and industrial corporation with core manufacturing concentrations in defense systems and defense and commercial electronics. It was previously involved in corporate and special-mission aircraft until early 2007. Raytheon is the world's largest producer of guided missiles.
..
In an effort to establish leadership in the defense electronics business, Raytheon purchased in quick succession Dallas-based E-Systems (1995), Chrysler Corporation's defense electronics and aircraft-modification businesses (1996) (portions of these businesses were later sold to L-3 Communications), and the defense unit of Texas Instruments - Defense Systems & Electronics Group (1997). Also in 1997, Raytheon acquired the aerospace and defense business of Hughes Aircraft Company from Hughes Electronics Corporation — a subsidiary of General Motors, which included a number of product lines previously purchased by Hughes Electronics including the former General Dynamics missile business, the defense portion of Delco Electronics (Delco Systems Operations), and Magnavox Electronic Systems.
..
Raytheon, often in conjunction with Boeing, Lockheed Martin or Northrop Grumman, is also heavily involved in the satellite sensor business.

Lockheed Martin

Body

From Wikipedia: Lockheed Martin:

Lockheed Martin is a multinational aerospace manufacturer, global security and advanced technology company formed in 1995 by the merger of Lockheed with Martin Marietta. It is headquartered in Bethesda, Maryland, in the Washington Metropolitan Area. Lockheed Martin employs 146,000 people worldwide.

Lockheed Martin is the world's largest defense contractor by revenue as of 2008.[1] In 2005, 95% of Lockheed Martin's revenues came from the United States Department of Defense, other U.S. federal government agencies, and foreign military customers.
