Abstract
In multi-purpose reservoir developments, a critical question is how to allocate joint costs among its many uses. In Japan, a commonly used method is SCRB (Separable Cost Remaining Benefit) Method. This and other commonly used methods are more useful but less clear in terms of the theory behind the reasoning of the solutions. In recent years, it is becoming more common that a multi-purpose reservoir is required to deal with various needs. Therefore it becomes a problem of whether the commonly used methods, for example SCRB, could be applied to new situations such as a multi-puipose reservoir. This paper presents the applicability of the conditions of the commonly used methods in terms of game theory.
