A heuristic, analytical model is developed to integrate the work in process storage space allocation and block layout planning steps of the facility design process. The model is applicable when identical unit loads are transported by a discrete materials handling system. The model is applied in the context of a ‘CRAFT like’ procedure where the user can reallocate storage space between departments on successive iterations while simultaneously considering materials handling volume distance and dynamically changing storage requirements. The scope of model inputs includes the layout, materials handling system attributes and production parameters. It is shown that the analytical nature of the model and scope of model inputs also allow the user to investigate significantly different production scenarios and materials handling system designs in layout planning. As a result, the model provides greater modeling flexibility than simulation and Petri net modelling in supporting sensitivity analyses in layout design. An example problem is used to illustrate application of the model.
