  • Patent number: 11443265
    Abstract: A cause of work loss in a factory that produces high-mix low-volume products is extracted. The analysis system includes: a calculation unit; a storage unit; and an input and output unit. The storage unit stores record information related to operation time of an activity for producing a product, and threshold information for determining whether the activity of producing the product is abnormal based on the operation time. The calculation unit is configured to determine the operation time and non-operation time for each case extracted from the record information, determine abnormality for each case based on the operation time for each case and the threshold information, and output information of comparing the operation time of a case determined to be abnormal with the operation time of a case not determined to be abnormal to the input and output unit.

  • Publication number: 20210405627
    Abstract: A production planning system includes: an influence degree calculation unit that calculates a degree of influence which is applied on a probability distribution of a workload in a predetermined production process of a product by determining an undetermined design specification item of the product; and a display control unit that causes the design specification item and the degree of influence to be displayed in association with each other.

  • Patent number: 11042823
    Abstract: Provided is a technique that appropriately predicts the degree of influence of each risk on business indexes according to a production situation and determines risks to be managed. A storage unit stores a table that stores risk propagation model master information and risk information. A processing unit includes a risk correction unit that corrects the risk propagation model master information and the risk information for each product, using at least one of a degree of progress and a degree of pressure and a risk score calculation unit that calculates a risk score on the basis of the corrected risk propagation model master information and the corrected risk information. An output unit outputs the risk score for each product in each process to a screen.

  • Publication number: 20200074529
    Abstract: Provided is a component ordering device that estimates an order condition that is possible to be accepted by a supplier with higher accuracy. The component ordering device includes: an order condition proposal generation unit that generates a plurality of order condition proposals when negotiating with a supplier for a component to be procured, based on negotiation history information that is established by negotiating with the supplier in the past for another component belonging to the same component classification with the component to be procured, the negotiation history information including an order condition provided with a lot size and a unit price; and an output control unit that outputs the plurality of order condition proposals.
