“…Traditional forecasting models were compared with Croston method and its variants, most results indicated that Croston methods and its variants gave inconsistent results for intermittent demand. It outperformed traditional methods with modest gains, and some studies even concluded that Croston method and its variants had inferior performance [2], [3]. AI/ML have gained a lot of attention in the recent past due to improvement in computational might.…”

“…Forecasting of intermittent demand focuses prevising of demand series where the interval between demands is remarkably greater than the unit time of the period forecasted. This results in several periods with no demand [2]. Requirement for intermittent demand items may be sporadic and considered as slow movers but can make up as much as 60% of the stock value [3].…”

“…Подготовка к первому шагу алгоритма Previous_Event =1 t_start = data_t [1] Далее в цикле происходит подбор параметров P для заданного количества событий. Функция Perebor оптимизирует параметры на сетке и возвращает лучшую комбинацию параметров, после чего в функции optNM2 с большей точностью происходит уточнение этих параметров.…”
