Abstract: A control system comprises: a control quantity calculating unit for calculating, on the basis of an operation target of a controlled object, an operation evaluation index, and an operation model, a control quantity for driving the controlled object, which is a working machine; and a model updating unit for updating the operation model on the basis of a state quantity of the controlled object. The control system may additionally be provided with: a command converting unit for converting the control quantity into a command value for a drive unit of the controlled object; and a conversion updating unit for updating a conversion characteristic from the control quantity to the command value, on the basis of the command value and a response of the controlled object.

Abstract: An operation management apparatus includes: a map converter that performs interconversion between a first individual section state corresponding to a first mobile object and a reference section state and interconversion between a second individual section state corresponding to a second mobile object and the reference section state; and a block control controller that determines the first individual section state and the second individual section state to prevent a collision between the first mobile object and the second mobile object based on conversion results of the map converter.
