And closed on Saturdays and Sundays. Here, when the business date and time is designated by the day of the week, the calendar information is necessary for the correspondence between the date of the simulation period and the day of the week, but in this embodiment, the Gregorian calendar is adopted.

  Further, as shown in the resource number setting file of FIG. 4, “resource A”, “resource B”, and “resource C” can be used in the business, and the number of available resources is “3”, “ 3 ”and“ 4 ”. Further, as shown in the resource information file of FIG. 5, the resources available for “Process A” are “Resource A” and “Resource B”, and the resources available for “Process B” are “Resource B”, “ Resource C ”. Further, the resource allocation rule is FIFO (First In First Out) to be allocated in the order of arrival.

  In this embodiment, when the order management unit 8 assigns an order ID to a new order, an integer is assigned in ascending order from 1.

[Detailed operation]
Hereinafter, a specific operation of the business simulator in the present embodiment will be described.

  The actual processing time calculation unit 21 of the processing time acquisition unit 2 selects the execution history file shown in FIG. 2 from the information storage unit 1 line by line in the event occurrence time, and performs the following processing for each line.

  First line: Since the event type is “start”, the line corresponding to the condition that the order ID is “1”, the process name is “process A”, the resource identifier is “resource A”, and the event type is “end” The second and subsequent rows are searched in order, and the event occurrence time of the first found row (second row) is extracted. Next, the difference between the event occurrence time on the second line and the event occurrence time on the first line is calculated, and the actual processing time “1401 (seconds)” as a result thereof, and the process name “processing A” on the first line, An actual processing time list (one row) is created by associating the resource identifier “resource A” and the event occurrence time “2006/10/2 10:31:12”, and stores them in the information storage unit 1.

  Second line: Since the event type is not “start”, nothing is done.

  Third line: Since the event type is “start”, the line corresponding to the condition of order ID “1”, process name “process B”, resource identifier “resource B”, and event type “end” The third and subsequent rows are searched in order, and the event occurrence time of the first found row (the eighth row) is extracted. Next, the difference between the event occurrence time on the 8th line and the event occurrence time on the 3rd line is calculated, and the actual processing time “12108 (seconds)” as a result thereof, and the process name “processing B” on the 3rd line, An actual processing time list (one row thereof) is created by associating the resource identifier “resource B” and the event occurrence time “2006/10/2 11:12:45” and stores them in the information storage unit 1.

  Fourth line: Since the event type is “start”, the line corresponding to the condition of order ID “2”, process name “process A”, resource identifier “resource A”, and event type “end” The fourth and subsequent rows are searched in order, and the event occurrence time of the first found row (fifth row) is extracted. Next, the difference between the event occurrence time on the 5th line and the event occurrence time on the 4th line is calculated, and the actual processing time “165 (seconds)” as the result and the process name “Processing A” on the 4th line are calculated. The resource identifier “resource A” and the event occurrence time “2006/10/2 11:33:12” are associated with each other to create an actual processing time list (one row thereof) and store it in the information storage unit 1.

  (Description of the 5th to 18th lines is omitted).

  19th line: Since the event type is “start”, the line corresponding to the condition that the order ID is “7”, the process name is “process A”, the resource identifier is “resource A”, and the event type is “end” The 19th and subsequent lines are searched in order, and the event occurrence time of the first found line (the 22nd line) is extracted. Next, the difference between the event occurrence time on the 19th line and the event occurrence time on the 22nd line is calculated in consideration of the business date and time.

  Specifically, regarding the start date, it is recognized that “2006/10/2” is “Monday” according to the calendar, and then the business hours of “Monday” are “9:00 to 18:00” from the business date and time file. ”. Then, “69 (seconds)” is obtained as the processing time in “2006/10/2”. Also, regarding the end date, it is recognized that “2006/10/4” is “Wednesday” according to the calendar, and then the business hours of “Wednesday” are “9:00 to 17:00” from the business date and time file. Recognize that. Then, “5493 (seconds)” is obtained as the processing time in “2006/10/4”. Further, business hours are acquired for all the dates between the start date and the end date. Actually, regarding “2006/10/3”, it recognizes that the business hours are “9:00 to 18:00”, and obtains “32400 (seconds)” as the processing time. Based on the above, the actual processing time of this processing is “37962 (seconds)”. The calculated actual processing time “37962” is associated with the processing name “processing A”, the resource identifier “resource A”, and the event occurrence time “2006/10/2 17:58:51” on the 19th line. A processing time list (one row) is created and stored in the information storage unit 1.

  By executing the above processing for all the lines recorded in the execution history file, an actual processing time list as shown in FIG. 7 can be obtained.

  Next, the processing time setting unit 22 of the processing time acquisition unit 2 reads the actual processing time list shown in FIG. 7 from the information storage unit 1 line by line, the processing name and resource identifier are the same, and the event occurrence time value is preset. Extract all applicable rows in one time zone for each specified counting unit / step, here every hour in the day, and process names, resource identifiers and actual processing times (actual times) of those rows. The processing time set) and the time zone (event occurrence time zone) are associated with each other to create an actual processing time set list (one row thereof) and store it in the information storage unit 1.

  The above processing is performed in the same manner as described above for the processing names, resource identifiers, and time zones that are different from each other, thereby obtaining (part of) the actual processing time set list as shown in FIG.

  Further, the processing time setting unit 22 of the processing time acquisition unit 2 reads the actual processing time set list shown in FIG. 8 from the information storage unit 1 line by line, and calculates a processing time that is an average value of each actual processing time. Then, a processing time setting file (one line) is created by associating the processing name, resource identifier, time zone (event occurrence time zone), statistical value type and the processing time of the row, and stored in the information storage unit 1 To do.

  By performing the above processing for each row in the actual processing time set list in the same manner as described above, a processing time setting file as shown in FIG. 9 is obtained.

  Subsequently, the order occurrence time list setting unit 4 reads the execution history file shown in FIG. 2 line by line from the information storage unit 1 and extracts a line whose process name is “Process A” and whose event type is “Start”. Then, the order ID and the event occurrence time are obtained, and these are associated to create an order occurrence time list (one row thereof). If there is no same order ID in the order occurrence time list, it is stored in the information storage unit 1 To do.

  By performing the above process for all the lines recorded in the execution history file, an order occurrence time list as shown in FIG. 11 is obtained.

  Subsequently, the initial setting unit 31 of the resource management unit 3 reads the resource number setting file shown in FIG. 4 from the information storage unit 1 and sets the resource number of each resource in the resource number setting file as an initial value at that time. A resource number list as shown in FIG. 10 describing the number of available resources for each resource is created and stored in the information storage unit 1.

Subsequently, the order management unit 8 stores the input start time “2006/10/1 0:00:00”, end time “2006/11/1 0:00:00”, and step “1 second”. The current time is set as the start time (S0).
