Diagnostic apparatus, diagnostic system, diagnostic method, and recording medium

A diagnostic method, performable by a diagnostic apparatus, the method comprising:

• receiving, from a target device, context information corresponding to a current operation on the target device and tool information regarding a tool being used for the current operation on the target device, the context information corresponding being one of a plurality of items of context information corresponding to one of a plurality of operations applicable to the target device;
• obtaining detection information of a physical quantity varying with the current operation on the target device;
• and
• determining a level of degradation of the tool being used, using the detection information and a model corresponding to a combination of the context information received and the tool information received, the model being specified from one or more models respectively corresponding to available combinations of context information and tool information using the combination of the context information received and the tool information received.

A non-transitory recording medium storing a computer program which, when executed by one or more processors, causes the one or more processors to perform a diagnostic method, performed by a diagnostic apparatus, the diagnostic method comprising:

• receiving, from a target device, context information corresponding to a current operation on the target device and tool information regarding a tool being used for the current operation on the target device, the context information corresponding to being one of a plurality of items of context information corresponding to one of a plurality of operations applicable to the target device;
• obtaining detection information of a physical quantity varying with the current operation on the target device;
• and
• determining a level of degradation of the tool being used, using the detection information and a model corresponding to a combination of the context information received and the tool information received, the model being specified from one or more models respectively corresponding to available combinations of context information and tool information using the combination of the context information received and the tool information received.
