Modeling and minimization of routing congestion

Maogang Wang, Majid Sarrafzadeh
2000 Proceedings of the 2000 conference on Asia South Pacific design automation - ASP-DAC '00

A Genetic Algorithm tool for optimising cellular or functional layouts in the capital goods industry

Christian Hicks
2006 International Journal of Production Economics  
The literature on the design of manufacturing facilities has two major themes: the application of Cellular Manufacturing, including the use of clustering methods; and the solution of facilities layout  ...  The approach can be used for either green field or brown field layout problems. The model was tested using a large data set from a collaborating capital goods company.  ...  When the layout was treated as a hierarchy of areas, the GA was not particularly sensitive to the levels of the GA parameters.  ...
