Component: environment

Component: PRL

\frac{d}{d time} (PRL) = rP \frac{1.0}{kD + DA} {(\frac{OT}{kO + OT})}^{2.0} - (qP PRL)

Component: DA

\frac{d}{d time} (DA) = qD (DA_infinity - DA) - vD vD = \{\begin{matrix} vDbar if time \geq 2.0 \land time ≦ 4.0 \\ 0.0 otherwise \end{matrix}

Component: OT

\frac{d}{d time} (OT) = rO \frac{x}{kx + x} - (qO OT + vO) vO = \{\begin{matrix} vObar if time \geq 2.0 \land time ≦ 4.0 \\ 0.0 otherwise \end{matrix}

Component: x

x = \{\begin{matrix} 51.0 if time \geq 2.0 \land time ≦ 4.0 \\ 51.0 if time \geq 16.0 \land time ≦ 18.0 \\ 1.0 otherwise \end{matrix}
