The model contains one compartment called C. There are four species called X0, X1, T and S1 and two parameters called k1 and k2. The model contains two reactions defined as:

Reaction Rate
X0 → T C · k1 · X0
T → X1 C · k2 · T

The model contains one rule:

Type Variable Formula
Algebraic n/a X0 + X1 + T − S1

The model contains one event that assigns value to species X1 defined as:

Trigger Delay Assignments
Event1 X1 > 2 X1 = 1

The initial conditions are as follows:

Value Units
Initial amount of X0 1.25 mole
Initial amount of X1 1.5 mole
Initial amount of T 1 mole
Initial amount of S1 3.75 mole
Value of parameter k1 0.1 second-1
Value of parameter k2 0.2 second-1
Volume of compartment C 1 litre

The species values are given as amounts of substance to make it easier to use the model in a discrete stochastic simulator, but (as per usual SBML principles) their symbols represent their values in concentration units where they appear in expressions.
