Evaluation index based device allocation method, system, and program

A logical device for implementing a service can be dynamically assigned to an available real device. A real device assignment request relating to a registered service program is transmitted to a real device assignment determination section (112) under the control of a registration management section (1111) of a service program management section (111). An assignment of a logic device relating to the service program to a real device is determined based on logic device information, real device interface assignment information, and real device information relating to an available real device under the control of the real device assignment determination section (112). Based on the assignment information, communication processing of a control command and data between the logic device relating to the service program and the real device to which the logic device is assigned.
