Abstract: Provided is a method for managing the failure of a facility which has the sufficient-accuracy results of reasoning, can estimate an optimal repair time for a failure or other failures which possibly occur simultaneously with or subsequently to some failure, and can be adopted in large equipment used in a plant. Â The method for managing the failure of a facility is designed in such a manner that a monitoring means monitors the operational state of a facility, and an estimating means estimates the cause of the failure of the facility by using as a node the measurement data about the operational state of a facility obtained by the monitoring means when the failure occurs in the facility, wherein acoustic data closest to a sound produced from the facility in which the failure occurred is selected from a plurality of elements of acoustic data provided previously, form data closest to the form of the facility in which the failure occurred is selected from a plurality of elements of form data provided previously, the acoustic data and form data thus selected are added to the node, and then the cause of the failure of the facility is estimated by a first Bayesian network based on the node. A combine, wherein a chaff sieve (59), the degree of opening of which can be changed, is provided at a sorting section (26) of a threshing device (3).Â  A support point shaft (67) is provided to a side portion of the chaff sieve (59), an operating shaft (65) which is connected to a support frame (64) which is pivotably supporting sorting plates is provided to the chaff sieve, an operating member (68) is connected between the support point shaft (67) and the operating shaft (65), and the operating member (68) is fixed to a side plate (27a) of a sieve case (27) through a positioning fixing member (70).Â  By this, the support frame (64) is fixed to set the degree of opening of the chaff sieve (59). Provided is a method for managing the failure of a facility which has the sufficient-accuracy results of reasoning, can estimate an optimal repair time for a failure or other failures which possibly occur simultaneously with or subsequently to some failure, and can be adopted in large equipment used in a plant.
