Description

CLAIM OF PRIORITY The present application claims priority from Japanese patent application JP 2021-72600 filed on April 22, 2021. BACKGROUND OF THE INVENTION This invention relates to a management system which manages whether a manufactured item is derived from renewable energy, and verifies that the manufactured item is renewable energy-derived. As the background art in a technical field of this invention, JP 2007-148726 A is known. In JP 2007-148726 A, there is described a manufacturing plant energy consumption analysis system in which a requested amount of each power or substance required for motivity is extracted for each manufacturing apparatus from input data in time series (a processing module 5), a requested amount of each required motivity power/substance is extracted for each process class in time series (a processing module 6), a time-series total requested amount is calculated for each required motivity power/substance from the apparatus-by-apparatus, or process class-by-process class, requested amount of each required motivity power/substance, and a time-series energy consumption amount is calculated based on energy data (a processing module 7), and pro rata calculation of the energy consumption amount is executed with the use of proportions of the apparatus-by-apparatus requested amount of each required motivity power/substance and the process class-by-process class requested amount of each required motivity power/substance to the calculated time-series total requested amount, to thereby calculate an individual energy consumption amount for supplying each required motivity power/substance for each apparatus and for each process class, and execute energy consumption analysis processing including transitions of a required motivity power/substance load and transitions of the energy consumption amount (a processing module 8). According to the technology as described in JP 2007-148726 A, an energy consumption amount of a whole manufacturing plant including utility apparatus can be analyzed with ease based on a lot flow of manufacturing apparatus, and not only review and planning of energy saving but also management of a ratio at which renewable energy has been used in a manufacturing process of a manufactured item is possible. However, it is difficult with the technology as described in JP 2007-148726 A to execute management for ensuring that a manufactured item is manufactured with the use of energy derived from renewable energy, and verify the use of renewable energy in the manufacture, in a manufacturing process that does not involve strict management of an association relationship between a manufacturing apparatus out of a plurality of manufacturing apparatus and a manufactured item out of a plurality of manufacturing items. WO 2014/065111 A1 discloses energy management for an entire factory in an energy management system such as a factory energy management system (FEMS). This energy management system has, for example, a FEMS that performs energy management for a factory, a production management system (PMS) that designs a production plan for the factory, and a storage battery system and a solar light power generation system capable of supplying electrical power to the factory. In collaboration with the production plan from the PMS, the FEMS performs a process whereby an adjustment that includes performing a peak cut or a peak shift with respect to the production plan information is performed. WO 2012/066651 A1 discloses using regional power by consuming surplus power in the region in which the surplus power is generated. In JP 2020 170484 A, an electric power energy source management system manages energy sources of power received in one or a plurality of facilities, and an electric power energy source management method is executed in the electric power energy source management system. SUMMARY OF THE INVENTION This invention has been made in view of this problem, and an object of this invention is therefore to provide a system and a method which are capable of executing management for ensuring that a manufactured item as well as parts and raw materials of the manufactured item is manufactured with electric power derived from renewable energy, and verification of a fact that a manufactured item as well as parts and raw materials of the manufactured item is manufactured with electric power derived from renewable energy, even in a manufacturing process that does not involve strict management of an association relationship between a manufacturing apparatus and a manufactured item. The technical improvement is achieved by the solution provided in accordance with the claims. The representative one of inventions disclosed in this application is outlined as follows. A management system for managing renewable energy verification of a manufactured item, the management system comprising: an arithmetic device configured to execute predetermined processing; a storage device coupled to the arithmetic device
