Whenever there are two interacting goal seeking structures which provide goals for each other there is the potential of creating oscillations because of the inherent delays in the structure. There is a also a video for this insight which is a component of the Systems Archetypes Course.
This structure begins as a standard goal seeking structure. The B1 Balancing loop acts as a goal seeking structure attempting to bring [result 2] toward [result 1].
While B1 Balance is functioning [result 2] ends up acting as the goal for [result 1] forming the balancing structure B2 Balance. With this relationship one might assume the structure would simply act as a Drifting Goals structure where [result 1] and [result 2] would stabilize at some value less than initially desired.
This proverbial fly in the ointment is the delay between [action] and [result 1] and [result 2] which are typically not even the same delays. When [result 2] gets to the [result 1] goal [result 1] is somewhere else so they end up chasing each other, typically oscillating back and forth.
In the simulation structure we've included [factor] to govern how intensely [action] influences [result 1] and [result 2]. We've also enabled [result 1] and [result 2] to be different.
Simulating this structure with different initial values for [result 1] and [result 2] with no delay and a relatively low value of [factor] shows essentially a dual Drifting Goals structure.
By introducing offset delays and increasing the value of [factor] we begin to see the dual dammed oscillation of the Goal Seeking with Delay structure.
Further increasing [delay 2] shows how the oscillations might not settle out for a long time and with further delay or increases in [factor] the structure is likely to end up out of control.
Strategy: The strategy for this structure is essentially the same as for the Goal Seeking with Delay and Drifting Goals structures. 1) Figure out if you can reduce the delay so you don't over react; 2) Reduce the rate of action so you don't over react; 3) A third possibility is to figure out how stop [result 1] and [result 2] from being the goals for each other though this one is seldom an option.
I would encourage you to interact with this structure to get a better sense of the interplay between [delay 1], [delay 2] and [factor]. You may find this a bit counterintuitive.
