Concurrent optimization in designing for logistics support
MetadataShow full item record
The evolutionary process which starts with the identification of a need and continues through design, production and retirement is known as a product's life cycle. Studies have shown that the decisions which are made initially, during the design of the product, will determine 80% of the total system costs. Several efforts have been initiated to improve the product design process and emphasize the life cycle approach. These include; Concurrent Engineering, Logistics Support Analysis (LSA) and Quality Function Deployment (QFD).
These efforts necessitate an overhaul of the decision-making methods used in the product design process. Consequently, within the military community and private industry, the time-honored sequential-hierarchical-decision approach to design is being replaced with concurrent decision-making. The sequential process of the hierarchical method can lead to suboptimal designs which significantly increase manufacturing and follow-on support costs.
