Annotatsiya: Ushbu maqolada konteyner tashuvlarini samarali tashkil etish va konteyner poyezdlarining optimal harakat yo‘nalishlarini shakllantirish masalalari tadqiq etilgan. Konteyner terminalida yuklarni belgilangan manzillarga o‘z vaqtida yetkazib berish, konteynerlarni vagonlarga to‘plash vaqtini qisqartirish hamda avtomobil transportidan temir yo‘l transportiga to‘g‘ridan-to‘g‘ri qayta yuklash ulushini oshirishga qaratilgan tashkiliy va texnologik yondashuvlar ko‘rib chiqilgan. Yig‘ma yo‘nalishli konteyner poyezdlarining muqobil marshrutlarini modellashtirish uchun transport tarmog‘i graf ko‘rinishida ifodalangan hamda konteynerlarni boshlang‘ich punktdan yakuniy manzilgacha yetkazib berish vaqtini minimallashtirish mezoni asosida iqtisodiy-matematik model ishlab chiqish yondashuvi taklif etilgan. Shuningdek, talab matritsasidan foydalanib, to‘g‘ridan-to‘g‘ri va yig‘ma yo‘nalishli konteyner poyezdlarini bosqichma-bosqich shakllantirish algoritmi ishlab chiqilgan. Modelni amaliy hisoblashda MS Excel dasturining “Yechimni qidirish” vositasidan foydalanish imkoniyati asoslangan. Taklif etilgan yondashuv konteyner oqimlarini ratsional taqsimlash, poyezd marshrutlarini optimallashtirish va temir yo‘l konteyner tashuvlarining raqobatbardoshligini oshirishga xizmat qiladi.
