reinforcing if, after going around the loop, one ends up with the same result as the initial assumption. balancing if the result contradicts the initial assumption. Or to put it in other words: reinforcing loops have an even number of negative links (zero also is even, see example below) balancing loops have an odd number of negative links.
The growth of the slowing action in turn reduces the current state, thereby creating a balancing loop. One example of this balancing loop is a situation where a number of units manufactured is increasing (current state), which causes the manufacturing utilization to increase (end eventually exceed capacity).
Balancing loop is a structure representing positive feedback process. This reinforcing feedback causes that even a small change in the system can lead to huge disturbances, e.g. variable A is increased which leads to an increase of variable B which leads to another increase of A and so there might be an exponential growth over time.
Balancing process intends to reduce a gap between a current state and a desired state. The balancing (negative) feedback adjusts a present state to a desirable target regardless whether the trend is descending or ascending. An example of the balancing feedback process is staying upright on bicycle (when riding). [1]
A simple negative feedback system is descriptive, for example, of some electronic amplifiers. The feedback is negative if the loop gain AB is negative.. Negative feedback (or balancing feedback) occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by ...
Figure 1. Causal loop diagram Figure 2. Stock and flow diagram. The system is made up of a reinforcing loop and at least two balancing loops. See causal loop diagram and stock and flow diagram for the insight into model fundamentals. The reinforcing loop (R1 in figure 1 and 2) represents accelerating growth – a growing action is producing ...
Fig. 1: Causal loop diagram. In system dynamics this is described by a circles of causality (Fig. 1) as a system consisting of two feedback loops. One is the balancing feedback loop B1 of the corrective action, the second is the reinforcing feedback loop R2 of the unintended consequences. These influence the problem with a delay and therefore ...
Positive feedback loops have been used to describe aspects of the dynamics of change in biological evolution. For example, beginning at the macro level, Alfred J. Lotka (1945) argued that the evolution of the species was most essentially a matter of selection that fed back energy flows to capture more and more energy for use by living systems. [31]
