Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual calculations and trial-and-error methods are used for time scheduling, then the process can be performed with simple tools, but the scheduling is labor-intensive and time-consuming
Solution Approach 1:
The patent replaces manual mechanical calculations and trial-and-error methods with a computerized simulation system that automatically generates and evaluates production schedules. The simulation tool uses digital modeling to compute optimal schedules based on input parameters, eliminating the need for manual iterative adjustments and significantly reducing the time required for scheduling while maintaining simplicity through automated processes.
2Adaptability or versatility
If manual time scheduling is performed by process engineers, then flexibility in adjusting schedules is maintained, but the scheduling results vary depending on engineer experience and may be suboptimal
Solution Approach 1:
The simulation tool incorporates feedback mechanisms by automatically evaluating generated schedules against multiple objectives and constraints, then iteratively refining the schedules to improve performance. The system provides feedback on schedule quality metrics and allows users to adjust parameters, with the simulation re-running to show improved results, thereby combining systematic optimization with user flexibility.
Solution Approach 2:
The system allows users to modify input parameters such as production targets, constraints, and objective weights, and the simulation automatically recalculates schedules based on these parameter changes. This enables flexible adaptation to different scenarios while maintaining consistent, reproducible results based on the specified parameters rather than individual engineer experience.
3Productivity
If thorough time scheduling is performed to account for all production factors, then resource utilization is optimized, but the scheduling process becomes excessively complex and costly
Solution Approach 1:
The simulation tool is designed as a universal platform that handles multiple production objectives (throughput, inventory, quality, cost) and various types of constraints simultaneously through a single integrated system. Rather than requiring separate complex procedures for each objective, the tool combines them into one comprehensive simulation that optimizes all factors together, reducing overall system complexity while achieving thorough resource utilization.
4Device complexity
If manual scheduling uses simplified approaches to reduce complexity, then the scheduling process is faster and easier, but resource utilization becomes suboptimal and margins are excessive
Solution Approach 1:
The simulation tool performs self-service by automatically generating optimized schedules without requiring manual simplification or approximation. The system independently evaluates multiple schedule options and selects the optimal solution based on the specified objectives and constraints, eliminating the need for users to simplify the process manually while still maintaining ease of use through automated operation.

AI summary
A computer device implements a method of scheduling production of packaged dairy products in a production plant by simulation. The method obtains a production target for dairy products to be produced and packaged in the production plant, recipes for production of the packaged dairy products, where each recipe defines ingredients and recipe activities, and production unit data that specifies existing production units and available fluid paths in the production plant and associates the existing production units with unit activities and production capacities. The method further performs the simulation by generating, as a function of the recipes and the production unit data, time schedules of recipe activities performed at least partly by one or more combinations of the existing production units to achieve the production target data, and evaluating the time schedules for selection of at least one time schedule for the production plant.
