Interactive multiple objective decision method for water supply scheduling in hybrid network models

In this paper, we propose an interactive, hierarchical architecture for wide-area water supply planning. Using the proposed architecture, we can make satisfactory schedules reflecting the decision-makers preferences. The system consists of an upper layer and a lower layer. The upper layer corporately generates the parameters used for the optimization in the lower layer. The advantage of our developed system is that the network parameters for optimization are not necessarily prepared beforehand but are generated automatically during the interactive decision process.

An Approach to Service Engineering via Harmonization of Systems Engineering and Knowledge Management

The proportion of the tertiary industry is increasing in the developed nations. Not only in service business but also in all industry including the manufacturing industry, offering service value has come to occupy important position in economic activities. Under such trend of service economics, it is required to find service value and to create service business model continually and systematically. We expect that an approach harmonizing systems engineering and knowledge management is effective for this purpose. This paper shows the possibility of our new idea through reporting a panel discussion in the study meeting related to trans-disciplinary science and technology.

A METHOD TO ESTIMATE WATER SUSPENSION CAUSED BY SEISMIC DAMAGE WITH REALTIME PROCESS INFORMATION

近年の相次ぐ災害を契機に, ライフラインの地震被害をリアルタイムに予測するための様々なシステムが開発されている. しかしその多くは, 直後の物理的被害を予測するに留まり, その後入手できる新しい情報を反映して予測を更新したり, 機能的障害を予測するまでには至っていない. 供給継続が強く求められる水道については, そういった機能への必要性が高い.阪神・淡路大震災下では, 流量と水圧というプロセス情報が, 水供給の重要な判断材料の一つとして役立っていたという現実を踏まえ, この情報を積極的に予測方法に取り入れることを試みた. これにより, 水道における機能障害である断水のリアルタイム予測をシミュレートし, その実用性について検討した.
