A New Flow Diagramming Scheme for Mapping and Analysis of Multi-Product flows in a Facility

The design of layouts for facilities that process a high variety of products requires the analysis of a large number of different product routings and their spatial representation on a planar layout of the facility. Traditionally, the representations of multiple product routings have been segregated into two categories: The From-To Chart, Flow Diagram and Multi-Product Process Chart are used for facility layout; whereas, the Machine-Part Matrix and Cluster Analysis Dendrogram are used for cell formation. This concept paper proposes a new charting tool - Modified Multi-Product Process Chart (MM-PPC) - that combines the capabilities of these traditional tools. The theoretical development of this new tool is explained and its utility illustrated using real-world layout problems.
