An expert system to generate associativity data for layout design

In this paper we present an intelligent system which assists the layout designer in producing associativity data as input to an automated layout generation tool. The approach which we adopt combines techniques based on expert systems, object-based data structures and cluster analysis. The system eliminates manual input for the associativity data. The object data structure assures data consistency. The cluster analysis determines the strength of relationship between any two pieces of equipment. The expert system provides guidance for the subjective part of the layout design. This results in automation of associativity data generation, an improved user interface, and consistency and accuracy of data. The concept is illustrated by an example taken from the petrochemical industry.
