Solution Overview
Problem
Complex industrial processes generate overwhelming volumes of data, making it challenging to ensure accurate and responsive simulation models, particularly due to the time-consuming and processing-intensive nature of solving large systems of equations.
Innovation Solution
A system that creates simulation models with connected ports and allocates memory locations as connection variables, treating simple equivalency equations as references rather than equations to be solved, thereby reducing the size of the solution matrix and improving simulation performance.

1Measurement precision
If traditional equation-solving methods are used to simulate process connections, then model accuracy is maintained, but simulation performance deteriorates due to increased processing time and computational intensity
Solution Approach 1:
The patent segments the solution process into two distinct phases: (1) a preprocessing phase that identifies and eliminates redundant connection equations before simulation, and (2) a simulation phase that solves only the necessary equations. This segmentation allows the system to maintain model accuracy while significantly improving simulation performance by reducing the computational burden during the actual simulation execution.
Solution Approach 2:
The patent applies preliminary action by performing equation analysis and redundancy elimination before the simulation begins. The system pre-processes the model to identify connection variables and remove equivalent equations from the solution set, so that during simulation execution, only the essential equations need to be solved, thereby maintaining accuracy while enhancing performance.
2Reliability
If all connection equations are included in the solution matrix, then complete model representation is achieved, but processing time increases due to the size of the solution matrix
Solution Approach 1:
The patent extracts and removes redundant connection equations from the solution matrix before simulation. By identifying equations that represent simple variable equivalencies (e.g., when two ports are connected, their variables are equal), the system takes out these redundant equations from the set of equations to be solved, thereby reducing the solution matrix size and processing time while maintaining complete model representation through the preserved connection relationships.

AI summary
A system for developing a simulation of a process. In one aspect, a system creates a first model within the simulation. The first model represents a part of the process and comprises a first port to which other models may be connected. The system also creates a second model within the simulation. The second model represents another part of the process and comprises a second port to which other models may be connected. The system then connects the first port and the second port together. Upon connection, the system allocates a memory location as a connection variable that represents a type of information transfer between the first and second ports. A first port variable, which represents a value transferrable through the first port, is set to reference the value at the allocated memory location. Similarly, a second port variable, which represents a value transferrable through the second port, is also set to reference the value at the allocated memory location.
