1. A remote operation assistance server comprising:
an evaluation result recognition element that communicates with a work machine comprising an actual machine operation mechanism and a mode switching mechanism that switches an actual machine operation mode in which the work machine is operated in accordance with an operation aspect of the actual machine operation mechanism to a remote operation mode in which the work machine is operated in accordance with an operation aspect of a remote operation mechanism that forms a remote operation apparatus and vice versa, recognizes as a first evaluation result a result of evaluation of whether or not the mode switching mechanism has switched the operation mode to the remote operation mode, based on the communication, and recognizes as a second evaluation result a result of evaluation of whether or not short-range wireless communication between the work machine and a portable terminal has been established, based on the communication;
a first assistance processing element that carries out a first assistance process of permitting remote operation of the work machine using the remote operation apparatus based on communication with each of the remote operation apparatus and the work machine when the first evaluation result recognized by the evaluation result recognition element is affirmative and the second evaluation result recognized by the evaluation result recognition element is negative; and
a second assistance processing element that carries out a second assistance process of prohibiting remote operation of the work machine using the remote operation apparatus when the first and second evaluation results recognized by the evaluation result recognition element are affirmative.
