Component: environment

Component: R

ddtime R = f1 - delta_R R

Component: U

ddtime U = f2 + d01 B1 + d12 B2 - delta_U U + alpha0 P U + alpha1 B1 U

Component: B1

ddtime B1 = alpha0 P U + d12 B2 - d01 B1 + delta_b1 B1 + alpha1 B1 U

Component: B2

ddtime B2 = alpha1 B1 U - d12 B2 + delta_b2 B2

Component: P

P = P0 + PE q q = 0.0 if time < ti 1.0 -- G time - ti if time < T + ti time ti G T - 1.0 G time - ti otherwise

Component: f1

f1 = a0 1.0 - B2 b + B2 + x 1.0 -- x a B2 b0 + B2

Component: x

ddtime x = s P - P0 P + P1 - delta_x x

Component: f2
