Initial Manufacturing Exchange Specification (IMES): Requirements Analysis forthe Plant Layout Applications



Yung-Tsun T. Lee


This Initial Manufacturing Exchange Specifications (IMES) specifies the use of the integrated resources necessary for the exchange of information for manufacturing plant layout. It defines an interface for conveying manufacturing plant layout information between design and simulation software applications. The information includes the basic data required for material flow analysis and activity analysis of the manufacturing plant, the significant features of the site on which the plant is located, the external shape and characteristics of the plant''s components or items, and the layout design. This IMES aims at designing or simulating a plant layout for discrete parts manufacturing with an initial focus on the engineering of small assembly lines for electromechanical products production.
