ABSTRACT:
In a development portion (2) of a directed graph, when a program specification (1) is provided, descriptive elements having characteristics of sets described in the specification and descriptive elements defining a calculation method described therein are mapped with vertices and arcs based on descriptive elements defining a calculation method described therein are drawn between the vertices. Thus, the program specification is developed to the directed graph. The developed directed graph is analyzed by an analyzing portion (3) in view of the characteristics of sets and mappings and global characteristics of the directed graph, and arcs and vertices where flows of execution timing of the calculation synchronize and arcs and vertices where flows of execution timing of the calculation do not synchronize are detected. A program structure defining portion (4) handles the arcs and vertices where the flows of timing synchronize and the arcs and vertices where the flows do not synchronize, by different methods, thereby determining a data structure and a procedure structure as the program structure.
