1. A remote operation server having a function of mutual communication with a plurality of work machines and each of a plurality of remote operation devices for remotely operating one work machine to be remotely operated among the plurality of work machines, the remote operation server comprising:
a state recognition element configured to recognize an index value indicating a level of a remote operation skill of an operator of each of the plurality of remote operation devices and a degree of difficulty of a work content through the one work machine;
a communication resource allocation process element configured to perform a communication resource allocation process for allocating, to each of the plurality of remote operation devices, a communication resource for mutual communication with the one work machine, based on the index value recognized by the state recognition element; and
an environment information control process element configured to perform an environment information control process for adjusting each of a plurality of environment information factors in a different manner or pattern according to a difference in the communication resource allocated by the communication resource allocation process element so that a data amount of environment data is reduced, the environment information factor being output in an information output device included in the remote operation device and defining an information amount of environment information according to the environment data acquired by an environment recognition device included in the work machine, the environment data indicating an environment of the work machine, wherein
the communication resource allocation process element performs the communication resource allocation process by outputting, to a specified output device, the index value recognized by the state recognition element and recognizing a state of allocating the communication resource for mutual communication with the one work machine to each of the plurality of remote operation devices, the communication resource being input through a specified input device.
