Evaluations for Industrial Land-Use Program Related to Water Quality Management

For analyzing a regional land-use program based on water pollution control, a hierarchical modeling of multilevel systems is presented. The overall, large scale objectives complex is decomposed into functional as well as regional subsystems. The device for coordinating and evaluating the sub-system is based on multiattribute utility analysis combined directly with dual variables obtained from mathematical programming. Shadow prices are used to derive the component criterion ("utility") functions which is a device for commensurating noncommensurate attributes. In the upper layer of the decision making system, uncertainty based on judgemental probability distributions is explicitly taken into consideration. This procedure is provided as a modified dynamic version of the nested Lagrangian multiplier method and is applied to the northern Senshu area in the Osaka prefecture of Japan.
