摘要： The present invention obtains information on parts embedded in a final product across a range of companies. The present invention comprises: a product life cycle management system, which is used by a manufacturing company that manufactures a final product by embedding parts that are operated by software, for managing information on the final product and the parts and the range of disclosure of data relating to software contracted between the manufacturing company and a providing company that provides the parts to the manufacturing company; and a product life cycle management system to be used by the providing company for managing the range of disclosure and software-related data that is data relating to the software. One product life cycle management system requests the other product life cycle management system to disclose the software-related data within the range of disclosure, and the other product life cycle management system transmits the software-related data to the product life cycle management system if the requested software-related data falls within the range of disclosure.

摘要： An object of the invention is to quickly reproduce a fault by quickly constructing a fault reproduction environment and providing information for a reproduction when a product fault occurs after vehicle shipment. A fault reproduction assist system that assists a fault reproduction of an abnormal vehicle includes a configuration information acquisition unit that acquires, based on configuration information that is received from the abnormal vehicle and that includes hardware information of hardware in which an abnormality is detected and vehicle configuration information stored in advance in a storage unit, configuration information including the same hardware information as the hardware information of the abnormal vehicle; a configuration information determination unit that acquires from the storage unit software that includes the same software information as software information included in the configuration information acquired by the configuration information acquisition unit, and a distribution unit that distributes the software acquired by the configuration information determination unit to a fault reproduction environment for reproducing a fault.
