Doctoral thesis of Philosophy: Location-allocation modelling for Indonesian multi-echelon LPG supply chain

This research is to design the Indonesian LPG distribution system through Location-allocation modelling taking into account the existing facilities. Location-allocation model is developed in fixed charge capacitated location-allocation problem considering transportation and inventory decisions. Multi echelon LPG distribution system is considered to be modelled from regional warehouse to agents. The objective of this research is to determine the candidate locations of regional warehouses and feeder filling stations optimally and evaluate the implications of the future changes as sensitivity analysis.
