The aim of this research is to present recommendations regarding transformation of the towel industry in Osaka area so that it can grow concurrently with increasing importation of towel products. For this purpose, we undertook a cybernetics/system approach to analyzing characteristics of the industry and its current problems through a field survey. The Osaka towel production firms are not only the number of the firms but also the amount of production has been decreasing since 1991, so that they applied for the textile safeguard to the WTO in February 2001. We define a transformation system is basically the learning system proposed by the SSM with VSM incorporated. From this viewpoint, we conducted on questionnaire analysis for manager’s senses and in-depth interview for a relevant system of the production firms. It is discovered that both the manager’s sound management and the manufacturing system had been effective until now, but they turned out to be lacking the requisite variety toward the complexities that have come from the diffusion of IT and economic globalization. We demonstrated a need for rational transformation to the industrial structure from the existing division of labor production to the coordinated supply system, in order to lead the industry out of the local maximum trap.

Moreover the role of the government will become more significant in adjusting the balance of import and export of products, based on welfare in a global free trade.

IDEF0 is a function modeling method for representing system requirements or business processes. The first objective of this paper is to consider IDEF0 methodology in the context of business model, taking its historical background into account. The second objective is to present a new scheme of IDEF0 methodology for business process modeling.

In this research, prerequisites for describing business model in IDEF0 are discussed in terms of three kinds of specifications - 1) material and information flows, 2) constraints to business process, and 3) customer’s process. Then, the interface model is introduced and the IDEF0 structure model is defined to acquire the business process model that satisfies those prerequisites.

Finally we take an example of package software business for applying our scheme. The business goes through three kinds of stages of business processes- founding stage, expansion stage, and innovating stage. Each stage is described in the schema and procedure to modify one stage as“’AS IS MODEL” to another as “TO BE MODEL” is presented.

Conceptual Form model, originated by Nakanishi in 1998, is a conceptual abstraction of external schema. Conceptual Form is a unit of logical data presentation with no constraints in implementation technique.

Conceptual Form Formula is an algebraic representation of the Conceptual Form, which is determined by the logical data structure of the target data source and its selected entity access path. This formula enables us to categorize a large number of actual screen/report forms into a manageable number of catalogued patterns.

This paper explains a catalogued list of extracted 50 Data Source Types, 435 Conceptual Form generation patterns, and 77 Conceptual Form Templates.

We have engaged in a research of EUD (End User Development) where a standard Prolog is extended as extProlog so that it can be used as a base language of our EUD. In order to make extProlog a satisfactory technological support of our EUD, an object oriented data base connectivity is realized for it using a conventional relational data base system. In this paper the data base manipulation in extProlog is formalized as a specification of the manipulation language and its implementation is presented in a theorem - proof form to be precise. The realized system performs the expected functions.
