Perancangan Produk D0394 Perancangan Sistem Manufaktur Pertemuan I - II
Product Design Idea Understanding and identifying customer needs Initial Design Feasibility study to determine initial functionality Prototype Market Research Market potential, economic analysis, strategic assessment Design Refinement Functional specifications Detailed Specifications Detailed design considering functions, quality/reliability, manufacturing, etc. Idea Generation ( Product Design ) Feasibility Study ( Performance Specification ) Preleminary Design ( Prototype ) Final Design ( Final Design Specification ) Process Planning ( Manufacturing Specication )
Product Design (Cont.) Functional analysis –Customer specifications –Product reliability Design for X –Manufacture or Assembly Simplification, standardization, modularization –Testing –Repair –Robustness to variations Concurrent engineering –Consider how product will be manufactured (process and production planning) during design phase Reduce cost and time to market
Product Design (Cont.) Computer-Aided Design –Use of computer graphics to assist in the creation, modification, and analysis of a design –Common uses Geometric modeling Automated drafting and documentation Engineering analysis Design analysis CAD/CAM –Generation of manufacturing instructions directly from CAD design data
Product Life Cycle Product (Consumer) Perspective –Inception –Design –Production –Use Maintenance and repair –Disposal –Reuse, recycle, scrap Production System (Manufacturer) Perspective Design Ramp-up Maturity Decline Time Sale
Production System Life Cycle Lifecycle –Inception –Design –Construction –Startup –Use –Closure Relationship to product lifecycle –Typically production system lifecycle is longer than an individual product’s lifecycle –Production system will revert to earlier stages in its lifecycle when new products are introduced Extent and cost depends on system flexibility
