Abstract

The information processing method of the present invention is provided that specifies an extraction period for extracting apparatus data to be generated by an industrial apparatus and analyzes a state of the industrial apparatus based on the apparatus data having an occurrence time within the extraction period. The information processing method includes a period changing step of changing the extraction period so as to enable the apparatus data required for the analysis of the state to be included, when the apparatus data required for the analysis of the state is not included within the extraction period.

Claims

1. An information processing method that specifies an extraction period for extracting apparatus data to be generated by an industrial apparatus and analyzes a state of the industrial apparatus based on the apparatus data having an occurrence time within the extraction period, the information processing method comprising:

a period changing step of changing the extraction period so as to enable the apparatus data required for the analysis of the state to be included, when the apparatus data required for the analysis of the state is not included within the extraction period.

2. The information processing method according to claim 1, further comprising:

an extracting step of extracting the apparatus data required for the analysis of the state from the apparatus data to be generated by the industrial apparatus within the extraction period,

wherein the extracting step further extracts the first information and the second information to pair with the first information, and the period changing step changes the extraction period based on a start time or a end time of the extraction period and the occurrence time of the first information and the second information.

3. The information processing method according to claim 2, wherein the period changing step determines the change of the start time when the second information is not present between the start time of the extraction period and the first information closest thereafter,

wherein the period changing step changes the start time to the occurrence time of the closest first information after the start time when a period change condition for delaying the start time in advance is set, and

wherein, on the other hand, the extracting step newly extracts the second information within an certain interval of time from the start time when the period change condition for advancing the start time in advance is set, and the period changing step changes the start time to the occurrence time of the second information closest before the start time.

4. The information processing method according to claim 2, wherein the period changing step determines the change of the end time when the second information is not present between the end time of the extraction period and the first information closest therebefore,

wherein the period changing step changes the end time to the occurrence time of the closest first information before the end time when the period change condition for advancing the end time in advance is set, and

wherein, on the other hand, the extracting step newly extracts the second information within a certain interval of time from the end time when the period change condition for delaying the end time in advance is set, and the period changing step changes the end time to the occurrence time of the second information closest after the end time.

5. The information processing method according to claim 1, wherein the industrial apparatus is an exposure apparatus.

6. An exposure processing system comprising an exposure apparatus, wherein when exposure processing is performed by the exposure apparatus, the information processing method according to claim 1 is employed.

7. A device manufacturing method comprising the steps of:

exposing a substrate by using the exposure processing system according to claim 6; and

developing the substrate.

8. An information processing apparatus that specifies an extraction period for extracting apparatus data to be generated by an industrial apparatus and analyzes a state of the industrial apparatus based on the apparatus data having an occurrence time within the extraction period, the information processing apparatus comprising:

a period changing section that changes the extraction period so as to enable the apparatus data required for the analysis of the state to be included, when the apparatus data required for the analysis of the state is not included within the extraction period.
