Abstract

PURPOSE:To define dynamic and multiplex hierarchical structure by assigning a logical line numbers meaning a logical coupling condition to one hierarchical structure. CONSTITUTION:A machine family is recognized as one hierarchical structure, logical line number codes (a coupling order code, a selection order code and a coupling state code) indicating the logical coupling order and state are set up to hierarchical relation at an optional level based on the product structure of a representative machine type and the structure of an object is uniformly regulated based on the set of the combinations. Namely, one hierarchical structure is selected as an object and relation between plural constitutional elements A, B having the hierarchical relation at an optional level is defined by using the logical line number to set up the reference unit of the structure. Consequently, technical data relating to the design and production of products can be uniformly controlled by using a generalized dynamic and multiplex hierarchical structure model capable of expressing the function constituting order and a multiplex and dynamic characteristics of the hierarchical structure.
