Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manufacturers face a significant burden in reducing CO2 emissions during production planning, as current systems do not efficiently incorporate emission reduction targets into production plans, requiring manual measurement and estimation of CO2 emissions.
Innovation Solution
A production support apparatus that predicts electric power charges and CO2 emissions for various power sources and generates production plans prioritizing emission reduction, delivery dates, or production costs, thereby automating the planning process and reducing the time and effort required.

Engineering Contradiction Analysis
1Object-affected harmful factors
If manufacturers manually measure and estimate CO2 emission amounts to reflect reduction targets in production plans, then CO2 emission reduction can be achieved, but the time and operational burden required for formulation of production plans increases significantly
Solution Approach 1:
The patent introduces a production support apparatus as an intermediary system that automatically calculates CO2 emission amounts based on production plans and power supply information. This mediator handles the complex measurement and calculation tasks, freeing manufacturers from manual burden while ensuring accurate CO2 emission tracking for production planning
Solution Approach 2:
The patent replaces the manual mechanical process of measuring and estimating CO2 emissions with an automated information processing system. The production support apparatus uses computer-based calculations to determine CO2 emission amounts, substituting human manual work with automated computational methods that are both faster and more accurate
2Object-affected harmful factors
If manufacturers manually measure and estimate CO2 emission amounts to reflect reduction targets in production plans, then CO2 emission reduction can be achieved, but the operational burden on manufacturers increases
Solution Approach 1:
The production support apparatus enables self-service by automatically performing CO2 emission calculations without requiring manufacturer intervention. The system autonomously integrates production plan information and power supply data to compute emission amounts, allowing the system to serve itself rather than requiring continuous manual operation by manufacturers
Solution Approach 2:
The production support apparatus acts as an intermediary that handles the operational burden of CO2 measurement, taking over the complex calculation tasks from manufacturers and providing automated results that reduce operational complexity and burden
3Productivity
If production plans are formulated based on specification, delivery date, and price without considering CO2 emission reduction, then production efficiency is maintained, but CO2 emission reduction targets cannot be achieved
Solution Approach 1:
The patent changes the parameters of production planning by incorporating CO2 emission amount as an additional optimization criterion alongside traditional parameters like delivery date and cost. The production support apparatus enables multi-parameter optimization where CO2 emission reduction can be balanced with production efficiency, allowing dynamic adjustment of production plans based on emission targets

AI summary
According to an aspect of the present invention, in assisting a production operation of a product by a production facility, prediction information of an electric power charge and a CO2 emission amount per unit electric power amount of each date and time is acquired for each of a plurality of electric power supply sources assumed to be used for the production operation, and information for specifying a production condition of the product from a terminal of a production requester is acquired. At least first production plan information prioritizing reduction of a CO2 emission amount is generated based on the acquired prediction information and information for specifying the production condition, and the generated first production plan information is output.
