Abstract

A process management apparatus allows even a user with a low level of technical skills to accurately and quickly estimate a failure factor when a failure occurs in an object of processing due to a failure of processing in a processing system that performs processing for the object. An estimation processor reads out information on conditions leading to failure factors from an estimation knowledge recording section and presents the conditions to a user as questions in order. Analysis IDs are associated with the respective conditions. A data processor receives analysis ID information of a condition corresponding to a question to read out data collection method information and data processing method information corresponding to a relevant ID, performs analysis in accordance with the data collection method information and the data processing method information, and presents an analysis result to the user.

Claims

1. A process management apparatus comprising:

an estimation knowledge recording section that records factor estimation knowledge information that associates one or more candidates of failure factors with each of plural failure results, which can occur in a processing system for processing an object, and includes information concerning conditions leading to the respective failure factors and analysis ID information corresponding to the respective conditions;

an analysis method recording section that records analysis method information of inspection result data concerning an inspection result of a process in the processing system and analysis ID information corresponding to the respective pieces of analysis method information;

a factor estimating section that estimates, on the basis of the factor estimation knowledge information corresponding to a specific failure result, a failure factor corresponding to the failure result; and

an analysis processing section that analyzes inspection result data on the basis of the analysis method information

wherein the factor estimating section presents the conditions required for estimation of a failure factor to a user as a question, and

the analysis processing section receives analysis ID information of the condition corresponding to the question to thereby perform analysis on the basis of the analysis method information corresponding to the ID and present an analysis result to the user.

2. A process management apparatus according to claim 1, wherein

the analysis method information is data collection method information that indicates which inspection result data should be collected out of the inspection result data and data processing method information concerning a processing method for data collected, and

the analysis ID specifies a combination of the data collection method information and the data processing method information.

3. A process management apparatus according to claim 1, further comprising:

an inspection result inputting section that receives inspection result data from an inspection apparatus that inspects a process in the processing system; and

an inspection result recording section that records the inspection result data received by the inspection result inputting section,

wherein the analysis processing section acquires inspection result data from the inspection result recording section and performs an analysis.

4. A process management apparatus according to claim 1, wherein the analysis processing section receives the analysis ID information according to an input from the user.

5. A process management apparatus according to claim 1, wherein

the factor estimating section transmits analysis ID information of a condition corresponding to a question presented to the user at the present point to the analysis processing section, and

the analysis processing section receives the analysis ID information from the factor estimating section.

6. A process management apparatus according to claim 1, wherein

the factor estimating section transmits information on a failure result to the analysis processing section, and

the analysis processing section performs an analysis on the basis of the information on the failure result received from the factor estimating section and the analysis method information.

7. A process management method comprising:

an estimation knowledge recording step of recording factor estimation knowledge information that associates one or more candidates of failure factors with each of plural failure results, which can occur in a processing system for processing an object, and includes information concerning conditions for the respective failure factors and analysis ID information corresponding to the respective conditions;

an analysis method recording step of recording analysis method information of inspection result data concerning an inspection result of a process in the processing system and analysis ID information corresponding to the respective pieces of analysis method information;

a factor estimating step of estimating, on the basis of the factor estimation knowledge information corresponding to a specific failure result, a failure factor corresponding to the failure result; and

an analysis processing step of analyzing inspection result data on the basis of the analysis method information,

wherein the conditions required for estimation of a failure factor are presented to a user as a question, and

in the analysis processing step, analysis ID information of the condition corresponding to the question is received, whereby analysis is performed on the basis of the analysis method information corresponding to the ID and an analysis result is presented to the user.
