1) Обоснование выбора поставщика и объемов поставки
2) АВС-анализ запасов
3) XYZ-анализ запасов
4) Системы управления запасами: с фиксированным размером заказа
5) Системы управления запасами: с фиксированным интервалом
6) Системы управления запасами: с установленной периодичностью пополнения запаса до постоянного уровня
7) Системы управления запасами: "минимум-максимум"
2.1. Обоснование выбора поставщиков и объемов поставки. Предприятие сотрудничает с четырьмя поставщиками – F1, F2, F3, F4. Необходимо определить их оптимальный состав при закупке 1, 2, 3, 4, 5, 6, 7, 8, 9 и 10 единиц материальных ресурсов соответственно, если известны затраты на закупку ресурсов (табл. 1.1).
