Operation method and operation system for operating production facilities of a same kind
An operation method for production facilities operates production facilities of a same kind located at production sites, and includes: a data information preparation step of aggregating operational data of each of the production facilities for each of the production sites; a data accumulation step of accumulating the operational data aggregated at the data information preparation step into a computer located at a data accumulation site; a data analysis step of analyzing an operation status of each of the production facilities, using the operational data accumulated at the data accumulation step; a data display step of displaying information on analyzed the operation status of each of the production facilities on a display unit located at each of the production sites; and a facility operation step of referring to the displayed information and operating a production facility located at a second production site from a first production site.
1. An operation method for production facilities for operating a plurality of production facilities of a same kind located at a plurality of production sites, the operation method comprising:
a data information preparation step of aggregating operational data of each of the production facilities for each of the production sites;
a data accumulation step of accumulating the operational data aggregated at the data information preparation step into a computer located at a data accumulation site;
a data analysis step of analyzing an operation status of each of the production facilities, using the operational data accumulated at the data accumulation step;
an operation status determination step of determining whether the operation is abnormal at each of the production facilities, based on an analysis result of the data analysis step;
a data display step of displaying information on the operation status of each of the production facilities analyzed at the data analysis step on a display unit located at each of the production sites; and
a facility operation step of referring to the information displayed at the data display step and operating a production facility located at a second production site from a first production site,
wherein the operation status determination step includes a step of determining whether the operation is abnormal, using an operation indicator, operational data and at least one piece of metadata of operating conditions, the operation indicator, operational data and operation conditions being converted into a same scale,
wherein the step of determining whether the operation is abnormal comprises using indices calculated for each of the production sites, wherein the indices are converted into the same scale by defining one index of the indices as a first index, calculating a mean value of the first index obtained in a period in which the facility is presumably normal in a production status in the past, and dividing the first index obtained sequentially by the mean value to yield a second index, whereby the facility statuses of the different production facilities of the same kind are compared.
2. The operation method for production facilities according to claim 1 , wherein
the data display step includes a step of displaying information on a current operation status of each of the production facilities on a display device located at a management site different from the production sites, and
the facility operation step includes a step of operating the production facility located at the second production site from the management site, instead of the first production site.
3. The operation method for production facilities according to claim 2 , comprising, instead of the facility operation step, an information presentation step of presenting, from the first production site or the management site to an operation operator at a production facility located at the second production site, operation guidance information on the production facility.
4. The operation method for production facilities according to claim 3 , wherein
the facility operation step or the information presentation step is performed when at least one of the production facilities is determined to have an operational abnormality.
5. The operation method for production facilities according to claim 1 , wherein each of the plurality of production sites includes a production facility of the same kind differing from each other in volume and shape.
6. The operation method for production facilities according to claim 1 , wherein the production sites are steelworks.
7. The operation method for production facilities according to claim 6 , wherein the facility is a blast furnace.
8. An operation system for production facilities for operating a plurality of production facilities of a same kind located at a plurality of production sites, the operation system comprising:
a data information preparation unit configured to aggregate operational data of each of the production facilities for each of the production sites;
a data accumulation unit configured to accumulate the operational data aggregated by the data information preparation unit;
a data analysis unit configured to analyze an operation status of each of the production facilities, using the operational data accumulated by the data accumulation unit;
an operation status determination unit configured to determine whether the operation is abnormal at each of the production facilities, based on an analysis result of the data analysis unit;
a display unit located at each of the production sites and configured to display information on the operation status of each of the production facilities analyzed by the data analysis unit; and
a facility operation unit configured to refer to the information displayed on the display unit and operate a production facility located at a second production site from a first production site,
wherein the operation status determination unit is configured to determine whether the operation is abnormal, using an operation indicator, operational data and at least one piece of metadata of operating conditions, the operation indicator, operational data and operation conditions being converted into a same scale,
wherein the operation status determination step unit is configured to determine whether the operation is abnormal by using indices calculated for each of the production sites, wherein the indices are converted into the same scale by defining one index of the indices as a first index, calculating a mean value of the first index obtained in a period in which the facility is presumably normal in a production status in the past, and dividing the first index obtained sequentially by the mean value to yield a second index, whereby the facility statuses of the different production facilities of the same kind are compared.
9. The operation system according to claim 8 , wherein each of the plurality of production sites includes a production facility of the same kind differing from each other in volume and shape.
10. The operation system according to claim 8 , wherein the production sites are steelworks.
11. The operation system according to claim 10 , wherein the facility is a blast furnace.
