To develop an intelligent system for aiding the operation of a chemical plant, it is indispensable to make the computer understand the meaning of functional structure inhering in the plant.<BR>In this paper, a methodology was developed by which all of the functions can be extracted by means of the function model proposed in another paper, when the PFD of a chemical plant and the material states of it are given. The hierarchical relation among the functions and an explanatory structure of it can be generated also. The outline of the methodology is as follows.<BR>First, by means of key-units, all of the main functions inhering in the plant can be extracted. Second, by using the knowledge of dependency among functions, the hierarchical relation of the plant's function can be generated. Here, the knowledge of structural conditions that a lowest-level-function has to satisfy and the semantics of each function are given in the form of data structure. By using this knowledge the explanatory structure of the hierarchical relation can be generated.
