IEEE, Piscataway, NJ,USA,97CB36134. p 694-698 CODEN: PMICETPublication Year: 1997Abstract: Space communications organizations, both civil andmilitary, have focused their attention primarily on the physicalŽ . Ž .layer 1 and data link layer 2 layers of the Open Systems

Ž .Interconnection OSI reference model. The need to reducespace operations costs, the expected availability of distributedcommunications architectures within space vehicles, and thedesign of increasingly complex space constellations have gen-erated civil and military requirements to provide functionssuch as end-to-end networking, data protection, reliable deliv-ery and file handling. Under a joint technical effort by the U.

Ž .S. Department of Defense DoD and the National Aeronau-Ž .tics and Space Administration NASA , space data communi-

cations protocols are being developed to provide these func-tions. The capabilities needed to be provided in these proto-cols are very much influenced by space communications con-straints in areas such as computing resources, data rates,contact time, delay and transmission errors. These new spaceprotocols have been submitted to both the U.S. governmentand the Consultative Committee for Space Data SystemsŽ .CCSDS for approval as standards. The commercial space,military tactical, and wireless personal communications com-munities, which have system and environment constraintssimilar to those encountered in space data communications,may also benefit from the technology of these space protocols.Ž .Author abstract 1 Refs.

The char-acteristics of this new production control system are as fol-lows. 1. The realization of full production control from manu-facturing request to product shipping, administration of logis-tics, administration of records. 2. The introduction of opensystems based on EWS and PC platforms considering future‘end user computing’. Some new functions are also incor-porated in this system. One is a production planning simula-tion system which applies the technique of mathematicalprogramming and the other one is a raw materials combina-tion system. This total system has been operating normally

This new system has been devel-oped based on open system technology, and reduces the sizeof the mainframe computer. Several functions of this systemhave been enhanced to improve the customer satisfaction; thetraceability of pipe quality, the quick delivery of pipe informa-tion, and so on.
