A new investment planning method is proposed to determine purchase of suitable production equipment considering demand fluctuations by using portfolio for manufacturing systems consisted of CNC machine tools and jobs in this research. The portfolios are set to consider candidates of the purchasing production equipment for investment.
Returns and risks considering demand fluctuations of the individual portfolios are required in order to select the best portfolio in the proposed investment planning method. The returns and the risks of the portfolios are calculated under assumptions that candidate production plans and probabilities that correspond to demand have already been obtained. Estimated profit is required to calculate the returns and the risks of the individual portfolios. The profit is estimated based on the cases where the production plans are carried out by using the purchased production equipment and existing equipment.
Evaluation method of the obtained portfolios is also proposed based on information ratio in this paper.
