System Engineering and Analysis Chapter 16 Design for Producibility and Disposability 6/28/2019
AFTER STUDYING THIS CHAPTER, YOU SHOULD BE ABLE TO: Differentiate impact on firm when producibility and disposability are internal or external; Produce with "green engineering" in mind Design for Producibility and Disposability through life-cycle costing Create meaningful quantitative measures Anticipate benefits through integration of life cycle.

Technical and Ecosystems Technical – Source for technological services substituting energy for human effort. (needs of civilization) Ecosystems – flood control, food, quality air and water 6/28/2019
Green Engineering Competitive differentiation – environmental impact Customer consciousness Government regulatory pressures Profitability improvements International standards 6/28/2019
Environmentally Conscious Design and Manufacturing EDCM -- industrial ecology Aim is to reduce the environmental impact through proactive approach to waste management and processes Design for environment (DFE) Environmental management (EM) 6/28/2019
4th Phase Product for producibility and disposability Concurrent engineering Life-cycle basis Directly, Partially reusable or not Demanufacturing – taking it apart Re-use Remanufacturing Recovery of raw materials 6/28/2019
Manufacturability Quick lead time Inexpensive Market measures – packaging, handling, storage, and transportation Forming Deforming Removing processes Joining processes Material properties modification processes Use fewer parts, gravity, design for ease of fabrication, reduce nonstandard parts, add more functionality Automate assembly (inserters, pre-oriented, stable directions, accessibility, handling, avoid flexible components 6/28/2019
