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.

Variable equivalency on connection in a process simulation

A system displays simulation data on a canvas. Software instructions stored on a memory device and executable by a processor display a first set of simulation data on a canvas, the first set of simulation data corresponding to a first zoom level of the canvas. Instructions adjust the canvas from the first zoom level to a second zoom level. Instructions display a second set of simulation data on the canvas, said displayed second set of simulation data corresponding to the second zoom level of the canvas.

Configuring process simulation data for semantic zooming

A system simulates a process entity. Software instructions stored on a memory device and executable by a processor create a plurality of entity type objects that generically represents a type of process entity. Instructions store the plurality of entity type objects in a shared repository. Additionally, instructions enable a plurality of users to access the plurality of entity type objects in the shared repository simultaneously.

Shared repository of simulation models

Software instructions stored on a memory device and executable by a processor generate a plurality of models to simulate a process entity. The models include equations that mathematically represent the functionality of the process. Moreover, the models are configured to accurately represent the functionality of the process. Instructions determine whether the equations of the models are solvable after each change made to the models and indicate the result of the determination of solvability of the equations. Changes to the plurality of models are suggested that may render the equations solvable if the equations are determined to be unsolvable.

Interactive feedback for variable equation specifications

A system simulates a process entity. Software instructions stored on a memory device and executable by a processor creates an entity type object that generically represents a type of process entity. Instructions create a simulation representing a process and instantiate an entity type instance in the simulation based on the entity type object. The entity type instance represents a specific process entity in the process. Additionally, instructions simulate the functionality of the specific process entity by the entity type instance in the simulation.

Entity type templates in process simulation

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.

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 transferable through the first port, is set to reference the value at the allocated memory location.

A system and method of creating and using a graphical task scheduler. A Graphical User Interface (GUI) allows a user to graphically build a real time flow task scheduler by providing a 'click & drag' functional palette which contains graphical flow chart elements. By creating this graphical flow chart, the user is able to associate a plant layout, or any subpart of the entire plant, to its associated mathematical model. With a graphical flow chart, the user can define one or more exit branches for each task. For tasks with more than one exit branch, the user can specify the conditions causing the sequence to use each branch. Once the flow chart is set up, it can be used as a sequence editor or scheduler. The sequence editor defines the sequence of tasks that will be performed by an on-line application, such as optimization, and also allows scheduling of the on-line application at specific times or periodic intervals. The scheduler controls the running of each sequence based on the scheduling information. Once a plant has been optimized by the graphical task scheduler, the optimized data may be used to control plant operations.
