Provided is an assistance device with which it is possible to discover optimal processing conditions more easily. An assistance device comprising: a program management unit that associates a plurality of verification results, in which a processing condition is verified using a verification function, with a processing program and stores the verification results in a verification result storage unit; an assessment unit that assesses whether each verification result satisfies a shape target value for a workpiece; and an advice unit that, when any of the verification results do not satisfy the shape target value for the workpiece, presents a modification of a processing condition on the basis of processing-condition-related information relating to the processing condition for the workpiece, the verification result, and the verification function.

To provide a program simulation system and a numerical control system that do not require a simulation on a machine operator's side and can mitigate or reduce a burden on the machine operator's side. A program simulation system for industrial machines that performs a simulation according to a program includes a machine selection unit that selects at least one industrial machine to be simulated; an identification data group creation unit that has a function to automatically add an identification code for specifying the industrial machine to the program after simulating a program for the industrial machine selected by the machine selection unit and create a data group of the program and the identification code; and a determination unit that determines whether the identification code in the data group sent to an industrial machine side matches an identification code of the industrial machine itself.
