Engineering Contradiction Analysis
1Ease of operation
If manual construction planning methods are used to coordinate tasks and locations, then flexibility in handling complex variables is maintained, but productivity and efficiency deteriorate due to time-consuming manual analysis
Solution Approach 1:
The patent replaces manual mechanical planning processes with an automated computer-based system that uses probabilistic risk models and Monte Carlo simulations. The system automatically analyzes complex task variables, location constraints, and resource availability to generate optimized schedules, eliminating the need for manual analysis while maintaining the ability to handle complex scenarios through algorithmic processing.
Solution Approach 2:
The patent transforms fixed deterministic task parameters into probabilistic distributions, allowing the system to model uncertainty and variation in task durations, resource availability, and location constraints. This parameter transformation enables automated analysis of multiple possible scenarios simultaneously, improving both efficiency and the handling of complex variables.
2Productivity
If automated construction planning is implemented using traditional methods, then productivity improves, but manufacturing precision deteriorates because traditional methods cannot accurately model risk and location-based constraints
Solution Approach 1:
The patent replaces traditional deterministic scheduling algorithms with probabilistic risk modeling and Monte Carlo simulation systems. This substitution enables automated processing while achieving higher scheduling accuracy by incorporating uncertainty analysis and statistical methods that better reflect real-world construction variability.
Solution Approach 2:
The patent changes fixed parameter values into probabilistic distributions, allowing the automated system to model and analyze the impact of uncertainty on project schedules. This transformation enables more precise risk assessment and scheduling decisions while maintaining automated efficiency.
3Manufacturing precision
If location-based task scheduling is performed manually to account for task variations, then scheduling accuracy improves, but loss of time increases due to the complexity of analyzing each task's location constraints
Solution Approach 1:
The patent replaces manual analysis of location-based constraints with automated computer-based probabilistic modeling. The system efficiently processes complex location variables, task dependencies, and resource constraints through algorithmic analysis, achieving high scheduling accuracy without the time burden of manual evaluation.
Solution Approach 2:
The patent performs preliminary probabilistic analysis and Monte Carlo simulations during the planning phase to pre-determine optimal schedules and identify potential risks. This preliminary action allows the system to account for location-based variations and task uncertainties before actual construction begins, improving accuracy while minimizing time consumption during execution.
4Reliability
If probabilistic risk models and Monte Carlo analysis are used for construction scheduling, then reliability improves through accurate risk modeling, but device complexity increases due to the sophisticated computational requirements
Solution Approach 1:
The patent implements a universal computational platform that integrates probabilistic risk modeling, Monte Carlo simulation, and schedule optimization functions. This multi-functional system handles diverse construction scenarios and variables through a unified framework, managing complexity while delivering reliable risk assessment and scheduling results.
Solution Approach 2:
The patent uses statistical distributions and probability models as abstract representations of real-world construction uncertainties. These mathematical copies allow the system to simulate numerous possible outcomes without requiring complex physical experiments or manual analysis of each scenario, achieving high reliability with manageable computational complexity.
Data Source
AI summary
A method for modeling construction risk is provided. The method includes providing a statistical model for each of a plurality of location-based tasks of a construction project model. A model parameter is randomly selected for each of the plurality of statistical models to generate a statistically-based duration for each of the location-based tasks. A schedule duration is then calculated using the statistically-based durations of the location-based tasks, and the steps of providing, randomly selecting, and calculating are repeated until a statistical distribution for the construction project model is generated, such as using a Monte Carlo analysis procedure.
