Production Planning Apparatus Dynamic Parameter Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing production planning systems face challenges in creating plans that meet delivery dates and ensure satisfactory productivity, particularly due to difficulties in adjusting for changes in production and transportation times, and the loss of critical know-how when personnel or facilities change, leading to potential shortages or excesses.
Innovation Solution
A production planning apparatus and method that includes a storage unit for actual performance data, a parameter generation processing unit to adjust planning parameters based on differences between planned and actual resource usage, and a production plan processing unit to calculate optimized production plans, ensuring timely delivery and high productivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standard values are replaced with actual values based on changes in production and transportation time and defect rate, then the production plan can adapt to current conditions, but it becomes difficult to adjust related information appropriately
Solution Approach 1:
The system dynamically adjusts planning parameters based on the degree of change in the planning master. When standard values are replaced with actual values, the system automatically calculates how much the planning master has changed and adjusts related parameters proportionally, making the system adaptable without requiring manual adjustment of each parameter
Solution Approach 2:
The system implements feedback by comparing the degree of change in the planning master with the required adjustments to planning parameters. This feedback mechanism automatically determines the appropriate adjustment magnitude, resolving the complexity of manually adjusting related information while maintaining adaptability
2Ease of operation
If production plans are created using fixed standard values, then planning is simple, but the plans cannot meet delivery dates when production and transportation conditions change
Solution Approach 1:
The system performs preliminary adjustment by calculating the degree of change in the planning master before finalizing the production plan. This preliminary action ensures that planning parameters are pre-adjusted based on current conditions, maintaining both simplicity and reliability in meeting delivery dates
Solution Approach 2:
The system changes planning parameters based on the degree of change in the planning master. When standard values are replaced with actual values, the system automatically adjusts related parameters to maintain the appropriate balance between planning simplicity and delivery date reliability
