Dinamička optimalizacija u opskrbnim lancima

Abstract

Production and stock optimization in supply chains is a complex problem because it determines the optimum quantity production in time. Due to their multileveld nature, those problems are mostly solved by different methods and models of dynamic programming. The problem discussed in this paper refers to the determination of optimum quantity of production and stocks within the supply chain in a certain period of time, as well as in each sub-interval of a period, but with the condition that the production and stock expenditure remains minimal and that the predetermined demand in every sub-interval and throughout the entire observation period remains satisfied. Optimalizacija proizvodnje i zaliha u opskrbnim lancima predstavlja iznimno sloÅ¾en problem, jer se radi o odreÄivanju optimalne koliÄine proizvodnje u vremenu. Takvi problemi se zbog svoje viÅ¡e-etapnosti najÄeÅ¡Äe rjeÅ¡avaju primjenom raznih metoda i modela dinamiÄkog programiranja. Problem koji se obraduje o ovoj znanstvenoj raspravi, odnosi se na odreÄivanje optimalne koliÄine proizvodnje i zaliha unutar opskrbnog lanca u odreÄenom razdoblju, kao i u svakom pod-intervalu toga razdoblja, pod uvjetom da troÅ¡kovi proizvodnje i zaliha, budu minimalni i da se zadovolji unaprijed zadana potraÅ¾nja u svakom pod-intervalu, a tako i u cijelom promatranom razdoblju.
