The purpose of this paper is to discuss human resource development (HRD) systems to create "the learning organization" based on the poly-agent system theory. HRD is one of the core activities for "the learning organization". First we examine theories and concepts of "poly-agent system" and "learning organization". Next we argue the current issues of HRD in firms and propose Soft Systems Methodology (SSM) to rebuild HRD systems. Finally an action research is implemented in a typical Japanese big company facing the competition. The findings show that SSM is one of the useful methodologies for rebuilding HRD systems in order to create " the learning organization".

Recently, various studies (outsourcing, business to business electronic commerce, etc.) have been done toward realization of virtual enterprises which can collect the core competence from wide range of companies. However, it may be hard that this enterprise type proliferates in the true sense, if a reasonable decision criteria is not established answering the question "Is it really all right if we outsource our process?" It is the problem of risk assessment that outsourced process cannot gain the expected output.

This paper proposes a solution about this problem. We assume that a certain capacity vector is requested to execute a certain process. We also assume an outsourcing candidate has a capacity vector, but the value of the vector is not a definite value but it has a probability distribution. We assume it a multi-dimension normal distribution. We propose a risk assessment method defining the risk as the probability that the candidate's capability does not exceed the requested capacity. Then we can assess the outsourcing risks.

Within the framework of this research the term computer integrated enterprise (CIE) describes the integration of all aspects of company operations. It includes management- related aspects split across all company activites including operations by humans. It is becoming extremely important to evaluate CIE systems and, within that framework, to consider and analyse the role of human and economical factors. In this paper, planning of a CIE system is represented as a combinatorial choice problem of different computer systems that have been implemented at various sections of an enterprise- An integrated evaluation model of CIE systems to facilitate a multi-criteria-based impact analysis is developed and presented, together with a novel multi-criteria evaluation method with improved Data Envelopment Analysis (DEA). Its effectiveness is illustrated by a CIE system planning problem implemented at six different sections of the selected enterprise.

We are developing an object oriented DB with Prolog as its host language. The development is done as one part of our EUD research. This paper discusses an implementation of the SQL function for the combination of the DB and Prolog. Although the objective of an object oriented DB and that of the SQL function are different from each other, our EUD requires our system to handle tables as SQL does. This paper presents a realization of the SQL function within the framework of our system. We observed that the system works as efficient as SQL does on handling with tables.
