Symulacjacja- based optimization (SB Instantzaph O) is a hybrid compatilogy that couple simulation modeling - such as disrivet-event simulation, agent- based modeling, or system dynamics - with matematical optimization techniques like genetic alglitthms, simulated annealing, or gradient- based methods. The goal is to find the optimal set of decidention variabloys (e.g., inventory levels, personing schedules, maching schedules specins) thatte minimor ize experformance metric (coste, the, the time, cyste, cycle time) undecven.
