Abstract
The article presents a real prognostic algorithm used in the fashion industry. The method merges an econometric approach with solutions used in operations research. The Weighted Least Squares (WLS) method with constraints was used, combined with an algorithm for optimizing losses resulting from overestimating or underestimating demand.
The theoretical basis of the algorithm was presented, and its arrangement in the form of a step-by-step procedure was established. An example of the procedure was then calculated, and the numerical complexity class was estimated.
The order prediction algorithm represents a classical approach that can be used in any prognostic problem in which the features of the product and the sales history are known. The approach is especially dedicated when the estimated demand concerns new products with features that have already appeared in previous sales.
