Maqolada sanoat, jumladan, yengil va to‘qimachilik korxonalarida elektr energiyasi iste’moli ko‘rsatkichlarini matematik tahlil qilishga yondashuvlar ko‘rib chiqiladi. Energiya iste’molining ishlab chiqarish hajmi, texnologik rejimlar va boshqa omillar bilan bog‘liqligini aniqlashda matematik statistika, dispersion, korrelyatsion va regression tahlil, shuningdek Chebishev polinomlari asosida yaqinlashtirish usullarining imkoniyatlari yoritiladi. Chebishev usuli uchun berilgan namunaviy ma’lumotlar qayta hisoblanib, koeffitsiyentlar eng kichik kvadratlar mezoni asosida aniqlandi. Natijada beshta eksperimental nuqta uchun o‘rtacha mutlaq foiz xatoligi taxminan 1,10 % ni tashkil etdi. Ko‘p omilli regressiya modellaridan foydalanishda omillarning birgalikdagi
ta’siri, model parametrlarining statistik ahamiyatliligi va tanlanma hajmini hisobga olish zarurligi asoslanadi. Taklif etilgan yondashuvlar energiya iste’molini meyorlash, energiya tejash zaxiralarini aniqlash va ishlab chiqarish rejimlarini baholash uchun metodik asos bo‘lib xizmat qilishi mumkin.
