Abstract

To reduce costs and work load in testing a construction machine operated without an operator by an agent.SOLUTION: A test support device simulates operation of a construction machine operated by an agent program, on a virtual environment to test the agent program, and the test support device comprises: a simulation unit which inputs information to be detected on the virtual environment by the construction machine into the agent program and simulates the operation of the construction machine on the virtual environment on the basis of responses from the agent program; a setting unit which modifies work conditions for the virtual environment and sets a plurality of virtual environments; and an output processing unit which causes a display device to display an index indicating performance of the agent program on the basis of simulation results on the plurality of virtual environments. The output processing unit uses at least one of the time required for the completion of work in simulation and a travel distance of the construction machine in simulation to calculate the index of work efficiency with the agent program.SELECTED DRAWING: None
