  • Patent number: 7970636
    Abstract: A controlling unit of a replacement part management server specifies a maintenance target equipment and acquires order conditions from a responsible personnel terminal. The controlling unit acquires maintenance information and part information both relating to the maintenance target equipment. The controlling unit calculates prediction residual regarding target parts of an initial value setting process, and compares the prediction residual with the shortest cycle. When the prediction residual is smaller than the shortest cycle, the controlling unit sets the number of replacements in the part order data storing unit. When an initial value setting process regarding all the parts is completed, an order input screen is output. When an order request is received from the responsible personnel terminal, an order management server acquires part order data and transmits a preparation instruction of a PM kit to the purchaser.

    Abstract: A demand prediction apparatus connected to an order reception record storage unit for storing an order reception record of a product and an association information storage unit for storing association information associating products with each other, first acquires identification information of a product for which demand prediction is to be performed. The demand prediction apparatus specifies a product associated with the product having the acquired identification information based on the association information stored in the association information storage unit, and acquires an order reception record of the specified product from the order reception record storage unit. The demand prediction apparatus derives a demand prediction function that is fitted to the order reception record, by using the acquired order reception record.

  • Patent number: 7202380
    Abstract: In a method of producing pyromellitic acid by liquid-phase oxidizing 2,4,5-trimethylbenzaldehyde in a water solvent with molecular oxygen, a recrystallization mother liquor separated in a recrystallization step is recycled to the oxidation step after a part of the water solvent is removed. With this method, the loss of pyromellitic acid and the oxidation catalyst can be minimized and the burden of discharging the waste water is reduced without lowering the efficiency of the liquid-phase oxidation reaction.
