Schedule Density Zooming for Project Scheduling Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current project scheduling tools lack interactive and automated summarized schedules with logic ties, limiting their utility for assessing progress and making adjustments, as they are static and devoid of total floats and critical paths, making it difficult to perform schedule calculations and convey plans to upper management.
Innovation Solution
An interactive and automated summarized schedule on a digital canvas with a hierarchy of logic-tied schedule densities generated from source schedule activities, allowing real-time zooming in and out to maintain logic relationships between summarized and detailed schedules, enabling users to visualize and calculate early start dates, late finish dates, and total floats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If static summarized schedules are used, then simplicity of display is improved, but logic relationships and critical path information are lost
Solution Approach 1:
The patent implements a hierarchical schedule display where summary groups contain individual activities, similar to nested dolls. Users can zoom in to see detailed activities within summary groups or zoom out to see only summary groups, maintaining logic relationships at all levels through the nested structure while keeping the display manageable and not overwhelming.
Solution Approach 2:
The patent transforms the static schedule display into a dynamic one by enabling zoom in/zoom out functionality. The schedule display adapts its level of detail based on user interaction, allowing the same schedule to be viewed at different granularities while maintaining logic relationships through the underlying data structure.
2Measurement precision
If detailed individual activities are displayed, then schedule precision is improved, but complexity of the display increases
Solution Approach 1:
The patent segments the schedule display into hierarchical levels with summary groups containing individual activities. Users can selectively view detailed activities or summary groups based on their needs, breaking down the complex entire schedule into manageable segments that reduce display complexity while preserving precision when needed.
Solution Approach 2:
The patent applies different levels of detail to different parts of the schedule display. Summary groups provide a high-level overview while individual activities within them provide detailed information. This local differentiation allows users to see detailed information only where necessary, reducing overall display complexity while maintaining precision for specific areas of interest.
3Measurement precision
If manual schedule updates are performed, then accuracy is improved, but time consumption increases
Solution Approach 1:
The patent implements automatic recalculation functionality where the schedule system automatically updates logic relationships, critical paths, and timing information when activities are added, removed, or modified. This self-service capability eliminates the need for manual recalculation by users, saving time while maintaining schedule accuracy through automated computations.
Solution Approach 2:
The patent incorporates real-time feedback mechanisms where changes to schedule activities automatically trigger recalculation of dependent activities, critical paths, and timing information. This immediate feedback loop ensures schedule accuracy is maintained without requiring manual intervention, as the system continuously updates itself based on changes.
Data Source
AI summary
An interactive and automated summarized schedule on a digital canvas includes a hierarchy of logic-tied schedule densities generated from source schedule activities and for which there is the ability in real-time to zoom in/out among the hierarchy of logic-tied schedule densities. For example, the hierarchy of logic-tied schedule densities is generated in response to and as the timescale (e.g., grid spacing) is compressed or stretched. This permits users to “zoom in” and “zoom out” on the digital canvas to observe the schedule activities individually or at various levels of summary groups that are summed-up from underlying individual activities, all while maintaining logic-relationships between the summarized groups.
