What is claimed is:1. A component mounting system comprising:a component mounting apparatus which mounts components supplied from a component supply member disposed in a component supplying unit on a substrate;a data creating apparatus which creates component data, which is a control parameter set for mounting the component on the substrate by the component mounting apparatus, for each component; anda component arranging operation supporting apparatus which includes an identification information acquiring unit that acquires component identification information given to the component supplying member, and a control unit which checks whether or not the component disposed in a predetermined position in the component supplying unit is a component to be disposed in the predetermined position based on the component identification information acquired by the identification information acquiring unit, whereinthe control unit of the component arranging operation supporting apparatus includes a component data creation requesting unit that transmits the component identification information acquired by the identification information acquiring unit and identification information related to an alternative component that is used as an alternative to the component to the data creating apparatus and performs a request for a creation of component data regarding the alternative component, andthe data creating apparatus receives the request from the component data creation requesting unit and creates the component data regarding the alternative component by copying the component data regarding the component that is replaced with the alternative component,wherein the component mounting apparatus is configured to mount the alternative component supplied from the component supply member to the substrate based on the component data regarding the alternative component created by the data creating apparatus.2. A method of a component mounting system that includes a component mounting apparatus which mounts components supplied from a component supply member disposed in a component supplying unit on a substrate, a data creating apparatus which creates component data, which is a control parameter set for mounting the component on the substrate by the component mounting apparatus, for each component, and a component arranging operation supporting apparatus which includes an identification information acquiring unit that acquires component identification information given to the component supplying member and a control unit that checks whether or not the component disposed in a predetermined position in the component supplying unit is a component to be disposed in the predetermined position based on the component identification information acquired by the identification information acquiring unit, the method comprising:causing the identification information acquiring unit to acquire identification information related to the component and identification information related to an alternative component that is used as an alternative to the component;causing the component arranging operation supporting apparatus to transmit both of the identification information related to the component and the alternative component acquired by the identification information acquiring unit to the data creating apparatus;causing the data creating apparatus to create component data regarding the alternative component based on both of the identification information related to the component and the alternative component received from the component arranging operation supporting apparatus; andcausing the component mounting apparatus to mount the alternative component supplied from the component supply member to the substrate based on the created component data regarding the alternative component,wherein the component data regarding the alternative component is created by copying the component data regarding the component which is replaced with the alternative component.
