On this page I tried to collect all projects that I considered to be of any value to me and probably will be useful for other people. Papers are grouped according to the subjects they belong to. The language of each project is denoted to the right of the title of a corresponding project. Every paper is in PDF format, thus, you will need Acrobat Reader to view them. In order to get a MS Word copy of any paper presented here contact me through my e-mail or in any other way.

Currently, I am working on Graduation Project and primary attention of this section of the site will be paid to its development. The topic of the project is "Supply Chain Modeling", however, primary concern is given to development of mixed integer programming optimization model of LPG (Liquefied Petroleum Gas) distribution network consisting of 6 primary filling and storing centers, 10 secondary ones and over 2000 dealers.



"Supply Chain Modeling" - Graduation Project
About the Project                                                                                                                  Top

Filling iconThe main purpose of this project is to develop a mixed integer programming model of the supply chain of AYGAZ A.S. - leading LPG (Liquefied Petroleum Gas) supplier in Turkey. Distribution system of AYGAZ A.S. consists of six primary and ten secondary LPG storages which supply LPG to more than 2000 locations. Development of mixed integer programming model of AYGAZ A.S. LPG supply chain is an attempt to optimize distribution strategy of the company by improving its distribution and storage policies.

Main purpose of the project undertaken by me is to construct a mathematical model of the supply chain of the company describing all transportation options and tactical decisions related to the structure of the supply chain. First part of the modeling stage will be to determine a generic model structure. In the second stage I plan to use a cluster analysis to determine near-optimal assignment of dealers to the filling facilities and by taking into account specific characteristics of the exisitng system to diminish the number of decision variables to a reasonable value.



Scope of the Project                                                                                                             Top

The goal of the project is to determine minimum costs of supply, storage, filling and delivery subject to supply limits, filling, product storage, truck load capacities and some other limitations of the system.

The structure of the model should enable to extract useful information in a form of reports, provide what-if analysis options and ability to add extra constraints and cost centers.
