Maqolada GMZ-2 ning hozirgi ishlab chiqarilishi misolida rudalarni tayyorlashni qayta taqsimlash samaradorligini oshirishga yo'naltiril-gan silliqlash sxemalarini takomillashtirish masalalari yoritilgan. Tajriba maydonchalarini sinovdan o'tkazish natijalari bo'yicha ularning samaradorligini oshirish uchun zahiralar aniqlandi. Sanoat sinovlari natijalari va sanoat miqyosida ishlab chiqilgan sxemani joriy qilish.
