ted with each simulation run. Real systems are not necessarily that predictable. Rather, some random element may determine the direction of a system’s behavior. This case is illustrated in the model developed in this chapter. Other sources of unpredictability of system behavior are discussed later in the book.

apter we turn our attention to positive feedback processes. Positive feedback reinforces a given tendency of a system and can lead a system away from equilibrium states, possibly causing quite unexpected results.

We will start the firm off with a low output per time period and calculate the corresponding profit. Then we incrementally increase output over time, thereby increasing revenues from sale of tha

Gradual Development of a Dynamic Modela simple system under alternative assumptions, this chapter shows how to expand and refine a model. Additionally, we want to stress the need for treating consistently the units in which parameters and variables are measured.

Two Independent Variables change in our models. First we introduce several stock variables to indicate various temporal aspects of the state variable of the system. Such a disaggregation can be done, for example, for a population into different age classes. Here we deal only with a more sophisticated representation of essen

Real systems are not necessarily that predictable. Rather, some random element may determine the direction of a system’s
