28-06-2020: A new cutting force model is on the way!
The StochasticDelayDiffEq.jl Julia package is now available and can be used for the numerical simulations of stochastic delay differential equations (e.g. stochastic models of machining , delay SIR epidemiology models considering stochastic perturbations [2,3]). This package can utilise a wide range of stochastic integrators, e.g., the Euler-Maruyama method, the implicit Runge-Kutta Milstein method, or even stabilised SROCK methods, to solve SDDEs. Furhtermore, the package can out-of-the-box use features from the DifferentialEquations.jl ecosystem, such as Monte-Carlo simulation and their statistical evaluation.
