Abstract
A management device includes: a blockchain that is configured to record transaction data of material of a product; a variation range registrar that is configured to register data on a variation range of a weight of material allowed in a transaction process to the blockchain; and a transaction data registrar that is configured to receive input of data regarding a transaction including data on the weight of material and registers the data of transaction to the blockchain.
Claims4
A management device, comprising:
- a blockchain that is configured to record transaction data of material of a product;
- a variation range registration unit that is configured to register, on the blockchain, data indicative of a variation range, the variation range being an allowable range of a weight of material in a transaction process;
- a transaction data registration unit that is configured to receive an input of the transaction data including data of a weight of material and is configured to register the transaction data on the blockchain;
- a variation range update unit that is configured to periodically update the data of the variation range based on a calculation using an actual measurement value of the weight of the material and the data of the weight of the material recorded on the blockchain;
- a determination unit that is configured to determine whether the actual measurement value of the weight of the material in the transaction process falls within the variation range registered on the blockchain;
- and
- an output unit that is configured to output a warning when the variation range is determined not to fall within the variation range.

A management system, comprising:
- a blockchain that is configured to record transaction data of material of a product;
- a management device comprising a computer having a processor and memory, the management device configured to provide:
- a variation range registration unit that is configured to register, on the blockchain, data indicative of a variation range, the variation range being an allowable range of a weight of material in a transaction process;
- a transaction data registration unit that is configured to receive an input of the transaction data including data of a weight of material and is configured to register the transaction data on the blockchain;
- a variation range update unit that is configured to periodically update the data of the variation range based on a calculation using an actual measurement value of the weight of the material and the data of the weight of the material recorded on the blockchain;
- a determination unit that is configured to determine whether the actual measurement value of the weight of the material in the transaction process falls within the variation range registered on the blockchain;
- and
- an output unit that is configured to output a warning when the variation range is determined not to fall within the variation range;
- and
- a user device that is configured to receive an input of the transaction data and to transmit the received transaction data to the management device, wherein
- the transaction data registration unit of the management device is further configured to register the transaction data received from the user device.
8 more elements
A management method for recording, on a blockchain, and managing transaction data of material of a product, the management method comprising steps of:
- registering, with a management device, data indicative of a variation range on the blockchain, the variation range being an allowable range of a weight of material in a transaction process;
- and
- receiving, with the management device, an input of the transaction data including data of a weight of the material and registering the transaction data on the blockchain;
- periodically updating the data of the variation range based on a calculation using an actual measurement value of the weight of the material and the data of the weight of the material recorded on the blockchain;
- determining whether the actual measurement value of the weight of the material in the transaction process falls within the variation range registered on the blockchain;
- and
- outputting a warning when the variation range is determined not to fall within the variation range.

A non-transitory, computer readable, tangible storage medium storing a program for recording, on a blockchain, and managing transaction data of material of a product, the program causing a computer to perform steps of:
- registering, on the blockchain, data indicative of a variation range that is an allowable range of a weight of material in a transaction process;
- and
- receiving an input of the transaction data including data of a weight of the material and registering the transaction data on the blockchain;
- periodically updating the data of the variation range based on a calculation using an actual measurement value of the weight of the material and the data of the weight of the material recorded on the blockchain;
- determining whether the actual measurement value of the weight of the material in the transaction process falls within the variation range registered on the blockchain;
- and
- outputting a warning when the variation range is determined not to fall within the variation range.
