Successful manufacturing system designs must be capable of satisfying the strategic objectives of a company. There exist numerous tools to design manufacturing systems. Most frameworks, however, do not separate objectives from means. As a result, it is difficult to understand the interactions among different design objectives and solutions and to(More)

Simulation is used to verify the feasibility of the design of manufacturing cells. The cell design, which combines new and existing machines in a component manufacture, is presented, showing the difficulties that can result with such a system. Simply changing the layout (arranging machines into cells) could provide some benefits, but these benefits were(More)
A framework was created to analyze manufacturing systems and assess the impact of various practices on system performance. A literature review of Lean Manufacturing resulted in the discovery of significant gaps in two areas: (1) modeling the effects of implementing Lean Manufacturing using control theory principles, and (2) a design framework for building(More)

In world where product life cycles are decreasing, and customers are demanding they receive high quality products in a timely manner; traditional 'mass' based production techniques based on hard automation are becoming uncompetitive. Mass production systems are unable to accommodate frequent model changes in an economic and timely fashion. One promising(More)
This paper contrasts the design of the manufacturing systems at two North American automotive component manufacturing plants with the Manufacturing System Design Decomposition (MSDD) 1. Manufacturing system designs should not be characterized based on name alone. Instead of characterizing a manufacturing system as " mass " or " lean, " it should be(More)
