BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a job schedule simulation device, and more particularly to a job operation management support device.

[0002]

2. Description of the Related Art As a conventional job operation management support apparatus, there is a method for managing the operation of a very large number of jobs, obtaining a probability of occurrence of an abnormality for all operation cases, and supporting the operation of job activation. . For example, Japanese Patent Laid-Open No. 3-1
No. 05524, “Computer System Operation Method Design Support System”.

FIG. 4 is a block diagram of an operation method design support system for a computer system. The execution control unit 17 activates the editing unit 18 upon receiving a job flow editing request from the terminal device 21, and the editing unit 18 executes the system. The edited result is stored in the job flow table 13 as a job blow that defines the execution order of the job group executed in (1).

Next, the simulation unit 19 is started up, and the simulation unit 19 refers to the job flow table 13 to calculate anomaly occurrence probabilities and execution times for all operation cases of the input job flow to calculate an operation case management table. 14 and the operation case table 15.
The operation case table 15 exists for each operation case and stores information for each operation case above.

The analysis unit 20 uses the operation case management table 14
And the operation case table group 15 for analysis, the results are stored in the operation case management table 14 and the operation case table group 15, and the simulation results stored in the operation case management table 14 and the operation case table group 15 [Operation case number: 1, 2, 3 ..., Abnormal end job number: (), (1), (1, 4) ..., Execution time (minutes): 45, 55, 70 ..., Abnormality occurrence probability: 0 ．
, 656, 0.066, 0.007 ..., etc. as a list on the terminal device 21 or a probability as an analysis result,
[-Execution time (min): 55, 6 after execution time change processing]
5, 80 ..., Abnormality occurrence probability: 0.510, 0.051,
0.005 ...,], etc. are displayed.

[0006]

In this conventional job operation management support system, job operation is simulated by the probability of occurrence of an abnormality for each job. Utilization of individual resources was not taken into consideration. Further, there is a problem that the fact that the actual job activation is limited by the number of devices such as MTs and the multiplicity cannot be expressed by the abnormality occurrence probability.

In view of the above problems, the present invention evaluates a job schedule, evaluates a device such as MT and the degree of multiplicity, and implements them by a pseudo job starting method that manages the number of devices such as MT and the degree of multiplicity. It is an object of the present invention to provide a job schedule simulation device capable of sequentially confirming the above.

[0008]

The present invention is a job scheduling system.
A device for simulating joules,

[0009]

According to the above configuration, the pseudo job activation device fetches the schedule of the device such as MT used by the target job selected by the job selection device from the schedule file by the notification from the MT management device, and executes the target job. Take in the multiplicity during the time by notification from the multiplicity control device,
The elapsed time measuring device compresses the previous actual elapsed time in the schedule file of the target job to measure and reduce the execution time, and starts the pseudo job.

Since the progress status of the target job is visually displayed on the display device, the schedule result of the target job can be evaluated and confirmed by a pseudo job starting method that does not actually start the job.
