Deterministic and stochastic inventory models
WebJan 14, 2024 · Stochastic models are appropriate for systems that inherently have randomness such as stock market, weather forecasting etc. On the other hand, … WebDeterministic system. In mathematics, computer science and physics, a deterministic system is a system in which no randomness is involved in the development of future states of the system. [1] A deterministic model will thus always produce the same output from a given starting condition or initial state. [2]
