What is a Model?

A SimBiology® model is a dynamic system described by a set of quantities and mathematical expressions.

Definitions and Evaluations of Rules

Rules are mathematical expressions that allow you to define or modify model quantities, namely compartment capacity, species amount, or parameter value.

Definitions and Evaluations of Reactions

A reaction is a mathematical expression that describe a transformation, transport, or binding process that changes one or more species.

Event Object

In SimBiology, an event is a discrete transition in value of a quantity or expression in a model.


Use doses to model different dosing regimens.

Pharmacokinetic Modeling Functionality

SimBiology software extends the MATLAB® computing environment for analyzing pharmacokinetic (PK) data using models.

Create Pharmacokinetic Models

SimBiology lets you create one-, two-, or multi-compartment pharmacokinetic models for model simulation and parameter estimation.

Component Usage

SimBiology lets you find species, parameters, and compartments that are not used in a model and find out how they are used.
