holds process-apparatus conversion information indicating a correspondence relationship between each process in the production process and an apparatus used in each process, and determines the apparatus used in the process designated under the calculation condition and creates the input parameter by using the server load information corresponding to the apparatus based on the work information and the process-apparatus conversion information.

3 . The server load prediction system according to claim 1 , wherein under the calculation condition, when a connection relationship between the apparatus and the server in the process is designated in addition to the designation of the process of predicting the server load, the server load calculation unit calculates the server load on the server based on the connection relationship designated under the calculation condition in the simulation.

4 . The server load prediction system according to claim 1 , wherein under the calculation condition, when the apparatus used in the process is designated in addition to the designation of the process of predicting the server load, the server load calculation unit calculates the number of the servers required to satisfy the apparatus requirement specification of the apparatus based on the apparatus designated under the calculation condition and calculates the server load on the sever after determining the server connected to the apparatus in the simulation.

5 . The server load prediction system according to claim 1 , wherein under the calculation condition, when the server specification and the number of the servers connected to the apparatus used in the process are designated in addition to the designation of the process of predicting the server load, the server load calculation unit calculates the server load on the server after determining the apparatus connected to the server based on the server specification and the number of the servers designated under the calculation condition in a range in which the server load does not exceed a capability of the server in the simulation.

6 . The server load prediction system according to claim 1 , wherein in the apparatus requirement specification,
information indicating an analysis model used by the server when information transmitted from the apparatus is analyzed is included in the work information; and a load applied to the server, which is caused by the analysis using the analysis model, is indicated in the server load information.

7 . The server load prediction system according to claim 1 , wherein the apparatus requirement specification includes the server load information based on data measured during an operation of each apparatus or the work information.

8 . The server load prediction system according to claim 1 , further comprising a determination unit that determines whether or not the server load calculated by the server load calculation unit satisfies a determination condition, the determination condition being further set with respect to the server load under the calculation condition,
wherein when the determination unit determines that the calculation result of the server load does not satisfy the determination condition, the input information creation unit changes the input parameter, and the server load calculation unit repeats processing of recalculating the server load based on the changed input parameter, and when the determination unit determines that the calculation result of the server load satisfies the determination condition, the output unit outputs the calculation result of the server load.

9 . The server load prediction system according to claim 8 , wherein in the changing of the input parameter, with respect to the apparatus and the server between which a connection relationship is assumed when the server load determined not to satisfy the determination condition is calculated, at least any one of information included in the apparatus requirement specification corresponding to the apparatus or information included in the server specification corresponding to the server is changed.

10 . The server load prediction system according to claim 9 , wherein the output unit outputs the server load determined to satisfy the determination condition, and the changed information included in the apparatus requirement specification or the changed information included in the server specification.

11 . The server load prediction system according to claim 1 , wherein when the apparatus requirement specification is changed in the production process,
numerical values obtained by statistical processing for the change are stored in the apparatus requirement specification storage unit, and the server load calculation unit calculates the server load by using the numerical values stored in the apparatus requirement specification storage unit.

12 . The server load prediction system according to claim 11 , wherein when at least some of the apparatuses and the servers are connected with each other by a wireless communication in the production process,
