Auxiliary tool allocation in flexible manufacturing systems

Article Abstract:

The problem of allocating the minimal number of tools to a flexible manufacturing system comprised of multipurpose machines with tool storage racks is considered. To this end, it is recast as a capacity expansion problem with single source constraints within an integer linear programming framework. Subsequently, a brand-and-bound based algorithhm, three heuristics and a Lagrangean relaxation for determining lower bounds are developed.

A unified framework for the selection of a flexible manufacturing system

Article Abstract:

A decision support framework is constructed to assist managers in deliberating issues related to flexible manufacturing system design and planning. Past procedures give greater attention to financial analysis and evaluation. The new framework seeks to integrate all relevant information resulting in the systematic analysis of long-term effects, medium-term tactical impacts and qualitative benefits at a strategic level.
