1Measurement precision
If global optimization methods are used to check all possible assignment combinations, then the optimal feasible combination can be found, but the computational cost becomes prohibitively expensive and impossible to compute for large projects
Solution Approach 1:
The patent transforms the discrete combinatorial optimization problem into a continuous probability distribution problem by using Monte Carlo simulation. Instead of evaluating discrete assignment combinations, the system samples from continuous probability distributions of task completion times to estimate project completion time distribution, thereby avoiding the exponential computational complexity of checking all possible assignments.
Solution Approach 2:
The patent replaces the mechanical exhaustive search method with a statistical simulation approach. Rather than systematically checking each assignment combination like a mechanical process, the system uses probabilistic sampling and statistical analysis to achieve optimization, substituting computational brute force with mathematical modeling.
2Productivity
If deterministic local optimization methods are used to check limited assignment combinations iteratively, then the methods converge and are computationally feasible, but they often get stuck in local optima that are far from global optimal
Solution Approach 1:
The patent introduces dynamic probabilistic sampling where the sampling distribution evolves during the optimization process. The Monte Carlo simulation dynamically adjusts the exploration of assignment combinations by sampling from updated probability distributions that reflect learned information from previous iterations, enabling the system to escape local optima while maintaining computational efficiency.
Solution Approach 2:
The system implements feedback through iterative Monte Carlo simulation where the project completion time distribution estimated from previous samples informs subsequent sampling decisions. The feedback loop allows the system to learn from previous assignments and adjust the search strategy, preventing stagnation in local optima while maintaining computational feasibility.
3Adaptability or versatility
If the number of tasks in a project increases, then the project becomes more complex and realistic, but the number of possible assignment combinations grows exponentially making optimization impossible under current IT infrastructures
Solution Approach 1:
The patent changes the fundamental parameter of optimization from discrete combinatorial space to continuous probability space. By representing task completion times as continuous random variables with probability distributions rather than fixed discrete values, the system transforms the exponential complexity problem into a polynomial complexity simulation problem that scales gracefully with project size.
Solution Approach 2:
The patent applies partial action by performing a limited number of Monte Carlo simulation iterations rather than exhaustively evaluating all possible assignments. This partial exploration of the solution space is sufficient to achieve good optimization results for large projects, trading complete exhaustiveness for computational feasibility while maintaining practical effectiveness.
