A structured methodology for implementing engineering data management

Abstract: One of the most significant positive effects on product and process development in recent years has been the application of data management techniques. Engineering data management or product data management is the most promising one. The implementation of engineering data management is heavily dependent on the engineering process and involves the technologies of management, engineering, and information. However, as there is no commonly acceptable approach and methodologies for implementing engineering data management, it’s implementation becomes a bottleneck. This paper presents a structured methodology for the implementation of engineering data management. The approach consists of a series of steps, from business and engineering process analysis, modeling and reengineering, through system design and modeling, to system realization. This research will facilitate engineering process improvement and the planning, design and implementation of engineering data management. Consequently, it will help increase product development capability and quality, reduce development cycle time and cost, and hence increase product marketability.

Engineering design change management

Abstract: Outlines the economic consequences of changes that are made during the design process and manufacture. Computer and paper based systems are considered, and the advantages of a computer based system are discussed. Experience in the use of a computer based system in a company is reviewed with respect to the sources of design changes, the control of design changes and the benefits gained. The use of bespoke and proprietary software is briefly discussed. Notes that engineering design change management plays an essential role in successful manufacturing organisations. Also notes that the bespoke system described has led to a considerable improvement in the company’s change control process.

Production and use of metals and oxygen for lunar propulsion

Abstract: Production, power, and propulsion technologies for using oxygen and metals derived from lunar resources are discussed. The production process is described, and several of the more developed processes are discussed. Power requirements for chemical, thermal, and electrical production methods are compared. The discussion includes potential impact of ongoing power technology programs on lunar production requirements. The performance potential of several possible metal fuels including aluminum, silicon, iron, and titanium are compared. Space propulsion technology in the area of metal/oxygen rocket engines is discussed.
