![]() For example, if 10,000 individuals each have a 95% chance of surviving one year, we can be reasonably sure that 9,500 of them will survive.Ī stochastic model, on the other hand, does have internal sources of randomness. ![]() It runs with the same set of input parameters and gives the same output results. There are two types of models: stochastic and deterministic.Ī deterministic model doesn’t have internal randomness. The software supports different distribution types: uniform, triangular, exponential, and more.īut what if none of the pre-set functions fits your project? You can create your custom (empirical) distribution and use it in your model. Probability distribution and custom distributionĪnyLogic offers a set of probability distribution functions to model non-deterministic processes, like weather changes, product demand changes, or any other randomness. How can you model this delay? In AnyLogic, you can set a probability distribution. You’re modeling a bank, and you’d like to know how much time a manager needs to open a new bank account for a client.įrom your experience, it takes at least 10 min., most likely 20 min., and 40 min. How can you set randomness in your AnyLogic model? ![]() For that, you would need to include randomness in your simulation. When we build simulation models, we want them to reflect the real world as closely as possible. However, the first guests could arrive at 10 one day and 9:50 the next day, it could be two customers or a dozen entering at the same time. Here’s a simple example: imagine you own a café that serves hot beverages and delicious pastry to around 100 customers per day. Uncertainty is an essential part of our everyday lives.
