摘要： An apparatus for planning a demand-supply scheme of a supply chain so as to increase the corporate profit. A demand-supply scheme including order receipt, order placement, purchase and supply in the unit of a month of each step of a supply chain that includes various steps, such as product sales steps, product-producing steps, steps of producing parts for producing products, etc. is set so that the order placement to each producing step becomes within an order receivable range that is calculated from the equipment, the manpower, the number of times of operation, etc. of the producing step. Furthermore, a demand-supply scheme is planned and changed so as to maximize a profitability index that is calculated by using a cost regarding the production of a product that includes a material cost, a manpower cost, and an equipment cost, a stock management cost, a transportation cost, etc.

摘要： A servo motor control apparatus effecting a feedback control of a servo motor according to an external operation command. The apparatus includes: an operational running state detecting unit for detecting a running state of the servo motor; a memory unit in which data representing inter-relation values are stored; a current value computing unit for computing an appropriate drive current value for the external operation comand; and a driving unit for driving the servo motor according to the computed appropriate drive current value. By defining the inter-relation values in advance in accordance with operational states of the servo motor so that a drive power of the servo motor approximates a value indicated by the external operation command and specifying an inter-relation value corresponding to the detected operational state with reference to the defined inter-relations to compute the appropriate drive current value, it is possible to compensate a phase difference between a current command value and an actual current irrespective of the rotational speed; and improve the response of the control apparatus to decrease a time lag of an output torque and a microscopic fluctuation thereof.
