Solution Overview

Problem

Existing production plan creation devices struggle to select the most favorable plan from multiple candidate plans based on varying evaluation indicators, as these indicators can differ by time and location, leading to suboptimal scheduling decisions.

Innovation Solution

A production plan creation device equipped with a processor that determines multiple candidate plans optimized for each evaluation indicator and displays them for comparison, allowing users to select the best plan based on comparable evaluation values.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple candidate plans are generated and displayed for comparison, then the ability to select the most favorable plan is improved, but the device complexity increases

Engineering Contradiction:

Improveability to select planVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The production plan creation device segments the evaluation of multiple plans by creating separate display regions for each candidate plan. Each region shows evaluation results for different indicators (production time, delivery time, machine utilization rate) independently, allowing users to compare plans segment by segment rather than overwhelming them with all data at once.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The device adds a visual dimension to plan comparison by using spatial arrangement of display regions and color-coded indicators. Evaluation results are presented across multiple dimensions (time, efficiency, utilization) with visual cues that make complex multi-criteria comparison intuitive and manageable.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Measurement precision

If evaluation results are displayed in detail for each candidate plan, then the measurement precision is improved, but the ease of operation deteriorates

Engineering Contradiction:

Improveevaluation value accuracyVSAvoidease of plan selection

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

Each display region is designed with localized quality features tailored to its specific plan. The first display region highlights production time metrics, while the second region emphasizes delivery time and machine utilization. This allows users to focus on locally relevant information for each plan without being overwhelmed by global complexity.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The device creates equipotential display conditions by standardizing the format and structure of evaluation information across all candidate plans. Each plan's evaluation results are presented with consistent indicators and visual weighting, making comparison straightforward without requiring users to adjust for different presentation formats.

Inventive Principle:

Principle #12Equipotentiality

AI summary

A production plan creation device includes a processor configured to determine, when creating a plan for multiple tasks performed to produce a product, multiple candidate plans having a most favorable value for each of multiple predetermined evaluation indicators, and cause the multiple candidate plans to be displayed such that the respective evaluation values of the multiple evaluation indicators are comparable.
