Dynamic layout design given a scenario tree of probable futures

Article Abstract:

A dynamic layout design model was developed by taking into consideration the future behavior and uncertainties of requirement sets. This model allows the scenario trees of probable futures to be developed. A requirement set represented as cell space and intercell interaction requirements are then specified for each future. These interaction requirements may be a combination of flow intensity and qualitative relationships. This design model was developed for use in conjunction with an overall dynamic layout design methodology.

Flow network design for manufacturing systems layout

Article Abstract:

A facilities layout planning problem can be solved using a component approach involving block design, input/output station location, material flow network design and aisle setting. The material handling network design phase of the problem is translated into a multicommodity-flow based formulation. Lagrangean relaxation is used to break up the shortest rectilinear flow network problem into manageable components that can be solved through a two-phase heuristic in linear time.

An O(nm) algorithm for a special case of the multimedian location problem on a tree

Article Abstract:

The multimedian location problem was solved via an O(nm) algorithm applied to a tree transport network. The problem involved n existing facilities occupying the vertices of a transport network and m new facilities which are to be located in the network. The distances between the facilities are the shortest-path distances along arcs of the network. Results indicated that Kolen's algorithm may be reduced from O(nm super 3) to O(nm) when the flow graph is series-parallel.
