An optimal planning method is proposed for the initial design of a plant, concerned with the determination of the scales and the numbers of constituent equipment. The optimal constitution and operational policy of equipment are investigated in order to minimize the total annual cost. This planning problem is first formulated as a mixed-discrete variable linear programming problem, by adopting discrete and zero-one integer variables indicating respectively the scales and on/off status of operation together variable of each piece of equipment are determined by the repeated application of the least squares method. Lastly, the optimal constitution and operational policy are derived numerically by using the extended branch and bound algorithm, and the validity and effectiveness of the proposed planning method is ascertained following the example of the optimal planning for a ship's energy supply plant.
