Abstract: Allowable constraint relaxation is achieved even when it is difficult to identify a constraint satisfaction solution. A production plan making device 1 that makes a plan related to a task has a production history DB2 that stores history information in the task, a past history reading unit 13 that reads the history information, a constraint relaxation unit 12 that identifies a deviation degree indicating a position relationship related to the constraint boundary of a constraint in making the plan of a history represented by the history information, calculates a weight indicating the degree of the constraint for constraint relaxation according to the deviation degree, and relaxes the weight when the plan cannot be made by an optimization process based on the weight, and a mathematical optimization unit 11 that makes the plan by the optimization process on the basis of the relaxed weight.

Abstract: An apparatus and/or method is proposed that can show evidence for judgment results in an abnormality judgment using a judgment model obtained by machine learning. Pieces of processed data with a mask corresponding to characteristics of waveform data set on a spectrogram of waveform data are created using a judgment model obtained by machine learning by sequentially shifting the mask in a direction corresponding to the mask, a change rate or a change degree of the waveform data of each piece of created processed data from the spectrogram is calculated, each area in which the mask on the spectrogram of the waveform data is set based on the calculated change rate or change degree is colored with a color or concentration corresponding to the change rate or change degree of the processed data when the mask is set so as to draw and display a judgment evidence image.

Abstract: A failure factor can be promptly carved up by effectively prioritizing the ports to which MEPs are assigned in a condition where the maximum number of MEPs is limited. A network monitoring server monitors a network having plural switch devices. The plural switch devices each have a communication confirmation function using transmission and reception of a monitoring frame between ports. An upper limit is set to the number of ports to which maintenance end points (MEPs) are assignable among the respective ports of the plural switch devices. The network monitoring server calculates, for each of the plural switch devices, a monitoring priority corresponding to the probability of failures of a device connected to a network path including the port or the port, and generates data for displaying the calculated monitoring priority of each port in association with each port.
