Financial risk management has become very serious on banking. Mathematical programming models based on the idea of ALM (Asset Liability Management ) which is the risk management on banking have been proposed by Hibiki et.al. The key problem to manage assets and liabilities is how to manage bank branches because the branches possess in practice almost all the deposits and loans in the bank. On the other hand, the management in the head office is also essentially required to implement ALM successfully. The corporate plan made in the head office needs further to be broken down into the operational plan taken effect on the branches. The existing ALM models have been studied as to the planning model in the head office. In this paper, an ALM model in consideration of branch management, which is called a two-stage model, is proposed. Finally, numerical examples are analyzed to investigate the usefulness of this model.

This paper presents designing a production information system for metal mold manufacturing. This system was designed to give useful information for interface between designing and manufacturing activities. The goal for designing an information system were stability in production, decreasing leadtime for design/manufacturing, quality improvement and information arrangement. First, this paper describes the production system for mold manufacturing, indicating the point at issue a newly developed production information system. The system designed for, this study showed more favorable results than the traditional system. The system designed has been useful tools as the decision support system for production control as well as the manufacturing lead time could be decreased and the office work could be simplified.

We have been engaged in research of DSS(decision support systems), which we call act DSS, including its development and applications. A DSS is supposed to support rational aspect of decision making. And to accomplish the requirement, it needs to use models. The MMS(model management systems) is characteristic of it. Models for a DSS must satisfy specific requirements. For instance,Non-professional people of computer must be able to construct, operate and modify DSS models easily. Most DSS models are constructed by arithmetic equations, and have comparatively simple but are mixtures of dynamic and static equations. Furthermore qualitative and non-numeric statements must be allowed for the models.

Although there may be other requirements, our experiences on constructions of specific DSSs tells us that a usable MDL(model description language) must satisfy at least these characteristics.

To satisfy these requirements, we propose a new MDL which is designed based on old MDL reported in [3]. As a result, the language satisfies them on a reasonable level.

In this paper, it is demonstrated that a DSS can be built for a business problem of a practical size on actDSS which is a DSS generater we have developed for the research purpose.

The actDSS adopts the model integration approach to generate a specific DSS. We applyed it to a business planning problem where organizational knowledge plays an importantrole and show that the approach is feasible in this large type of problems.

It has been pointed out to be crucial that a user is supported in model management so that he can build his model by himself. The model integration approach of actDSS allows the user to select, modify or conbine submodels in the model base freely, and thus gives a solution to the model management problem.
