Abstract

Supply of LPG to fuel-station network is done in a centralized manner on the basis of sales analysis on individual stations. Such an organization of the process allows the use of advanced approaches to distribution planning concepts such as VMI (vendor managed inventory). In operational research area these issues are referred to as IRP (ang. inventory routing problem). This paper presents a real problem of supply planning of LPG to fuel-stations. The mixed integer programming model is considered to support planning process. Unfortunately the use of algorithms known in the literature, due to the additional constraints such as different variants of routes (with or without loading), as well as various start and load locations was not possible.
