The part order quantity determination device has an input unit receiving an input such as an allowable out-of-stock rate of each product, a storage unit storing the allowable out-of-stock rate of each product, constituent parts of each product, the number of parts, a demand quantity distribution product by product, and an order quantity of each part, a part-by-part order information calculation unit virtually calculating a demand quantity in each calculation period from the demand quantity distribution of each product, calculating a necessary quantity of constituent parts by multiplying the calculated demand quantity with the number of constituent parts, calculating an order quantity of each part, calculating an out-of-stock rate of each product, calculating an out-of-stock rate of each part at which the out-of-stock rate of each product does not exceed the allowable out-of-stock rate, and determining the order quantity, and a display unit displaying the order quantity of each part.

A device (100) for calculating the amount of safety inventory of a common component commonly used in products comprises a required-amount deviation calculating section (111) for determining the required-amount standard deviation of the common component using the demand standard deviation of each product, an integrated required-amount deviation calculating section (112) for determining the required-amount standard deviation of the common component of all the products as an integrated required-amount standard deviation using the required-amount standard deviation of the common component of each product, and a safety inventory amount calculating section (116) for determining the safety inventory amount of the common component using the integrated required-amount standard deviation. The integrated required-amount deviation calculating section (112) has a correlation coefficient calculating block (113) for determining a correlation coefficient representing the correlation among the required amounts of the common component of the products from the past records of the required amount of the common component of each product and a primary integrated required-amount standard deviation block (114) for determining an integrated required-amount standard deviation using the correlation coefficient and the required-amount standard deviation of the common component of each product.

A production plan is created so as to minimize risk of demand variations. Forecasted values of amounts of requests are entered for each different item of products, markets, dates, past accuracy of demand forecasts, and order achievements at the time when the plan is created. Scenario information is created in which assumable amounts of request for each different item of the products, markets, and dates and probabilities at which the amounts of requests agree with actual amounts of requests are defined. Management indexes are found from the amount of stockout and amount of stock calculated in each different scenario, based on the scenario information, target values of the management indexes, and information on strongpoints. An amount of production that maximizes the achievement ratios of the management ratios to their targets within the ranges of supplied materials and within the range of the production capacity is calculated by an optimization algorithm.

An investment plan planning apparatus being a computer apparatus that evaluates a fund in hand and an investment effect of the fund in hand to estimate an investment plan relating to product production, comprising an input unit that receives information from a user to store in a storage unit, the storage unit stores at least prediction information related to a period for debt collection from a customer, prediction information related to a period for debt payment to a supplier, actual sales information of a product, demand information predicted for the product, and actual purchase information of items and services required for product production, received by the input unit from a user, and a computing unit executing the processes of identifying a collection period of accounts receivable related to a predetermined product from the actual sales information of the product, demand information of the product, and a prediction information of the debt collection period related to a customer of the product, identifying a payment period of accounts payable generated at a time of production of the product from an actual purchase information and the demand information related to the product, and calculating a cash flow by subtracting an accounts payable payment amount from an accounts receivable collection amount of each period, comparing movement of the calculated cash flow for a case when the cash flow is not used for investment with an investment amount defined by a user through the input unit, identifying as an investable term a term when an amount of the cash flow exceeds the investment amount, calculating fund in hand and an investment effect when the fund in hand is invested in a user-specified investment target for the investable term, and identifying an investment period causing a maximum investment effect and an investment amount therefor, and displaying the cash flow movement and pieces of information of the investment effect on a display unit.
摘要:
The invention displays multiple inventory period combinations, as multiple multi-base inventory deployment proposals having assessed values for items such as cash flow and inventory value, each of said assessed values being within a range entered by an inventory deployment decision-maker. For each product included in request information, the invention finds a minimum period (the total lead time from when a given item leaves the applicable warehouse until the item reaches the base that sells the applicable product) and a maximum period (the total lead time needed for all component parts configuring the item to reach the warehouse, added to the minimum period), for each item configuring said product and each warehouse base. The invention computes product-specific inventory period combination information for each warehouse base, and creates inventory period combination information by combining said product-specific inventory period combination information for each product type. The invention performs an inventory management calculation for the inventory period combination information, computes the value of an assessment index, and compares said value to the maximum value thereof. The invention selects an inventory period combination having an assessment index value within a permitted range, as a candidate display proposal. For the candidate display proposal, the invention computes a display evaluation value for each display proposal evaluation item by multiplying a display evaluation coefficient by an inventory value.
