Stochastic Modeling Definition - Investopedia

WebA deterministic inventory model is one where inventory control is structured on the basis that all variables associated with inventory are known, predictable and can be predicted with a fair amount of certainty. Because of this, inventory is counted, tracked, stocked and ordered according to a stable set of assumptions that largely remain the same.
