Characterization of manufacturing (Wright, Ch1-2) • Technology • Production Technology
Production Technology • Manufacturing • Construction • "Processing” • Service? • Other?
Manufacturing = • “systems that transform materials into products in a central location (factory)” (Wright, p.25) <sic.>
Manufacturing = • “A series of interrelated activities and operations that involve product design, and the planning, producing, materials control, quality assurance, management, and marketing of that product” (Biekert, p.348)
Manufacturing = • “Building and servicing products that are not attached to a site”
Manufacturing systems • Systems approaches • List the subsystems of manufacturing
Modeling manufacturing systems • IPO; Universal Systems Model • DPUA • PTUD • Production Technology Cycle (Ritz)
IPO • Input --> Process --> Output • Goals • Feedback
DPUA • Design • Produce • Use • Assess
PTUD • Procurement • Transformation • Utilization • Disposition
Procurement (getting) • Harvesting • Extracting
Transformation (changing) • Separating • Combining • Conditioning • Forming • Casting and Molding • Finishing • Other
Utilization • by industry • by end consumer • reuse
Disposition (getting rid of) • Reusing • Recycling • Storage • Air • Land • Water • Space
"Production Technology Cycle” • Materials Formation • Extraction • Materials Processing (primary) • Transformation (secondary) • Marketing • Servicing • Recovery • (back to Materials Formation)
Benefits of Production Technology • Economic Growth • Employment • Meeting consumer wants • Creating a diversity of products • Product improvement • Other
Drawbacks of Production Technology • Material resource depletion • Energy Depletion • Pollution • Short-Life Products • Materialism (Throw-away attitudes) • Technophobia • Other
The goals of manufacturing • Classic, capitalistic: “To increase the profits of the company” • “To improve the well-being of humans” (Ritz, p.39) • What would be a better goal?
Major Stages in the Evolution of Production Systems • Household (within the home; no surplus) • Handicraft (home or shop; surplus) • Factory (centralized; mass production) • Automated (automated machinery) • Cybernetic (totally controlled by computer) • [What might the next stage be?]
