Abstract

U uvjetima povećane potražnje za naftnim derivatima županija po mjesecima javlja se
potreba za optimizacijom sekundarne distribucije kako bi se osigurala sigurna opskrba tržišta i
zadovoljstvo kupaca uz optimalne troškove distribucije. Optimizacija sekundarne distribucije
može se modelirati kao problem linearnog programiranja. U ovom je radu opisan problem
sekundarne distribucije kompanije INA, d.d. kao zatvoren transportni problem i matematički
modeliran kao problem linearnog programiranja te riješen uz pomoću programskog alata Excel
primjenom rješavača i simpleks metode. U obzir su uzeta dodatna ograničenja o udaljenostima
između skladišnih lokacija i županija koja definiraju broj dnevnih obrta autocisterni i kapacitete
linija. Na osnovu navedenog izračunat je potreban broj autocisterni na pojedinim skladišnim
lokacijama za svaki mjesec. Konačno, s obzirom na mjesečnu potražnju tržišta dodatno je
optimizirano trčanje praznih autocisterni između skladišnih lokacija kako bi se efikasno
iskoristili slobodni transportni kapaciteti.

Abstract (english)

In conditions of increased demand for petroleum products across counties each month,
the need arises to optimize secondary distribution to ensure secure market supply and customer
satisfaction with optimal distribution costs. The optimization of the secondary distribution can
be modeled as a linear programming problem. This paper describes the secondary distribution
problem of the company INA, d.d. as a closed transportation which is mathematically modeled
as a linear programming problem and solved using Excel with the application of Solver and
the simplex method. Additional constraints regarding distances between storage locations and
counties, which define the number of daily tank truck trips and line capacities, were considered.
Based on this, the required number of tank trucks at each storage location for each month was
calculated. Finally, considering monthly market demand, the running of empty tank trucks
between storage locations was further optimized to efficiently use available transport
capacities.
