BIOMASS LOGISTICS MANAGEMENT FOR BIOGAS POWER PRODUCTION FACILITY
Journal Title: Endüstri Mühendisliği - Year 2017, Vol 28, Issue 3
Abstract
The biogas power plant, which generates energy from biomass, uses animal waste to reach its energy production target, and it hasstarted to collaborate with about 150 farms within the area. In this project, the amount of waste in farms, the number of farms and their proximity to each other are examined under multi-objective functions to transport the waste needs of the plant from the farms, then the number of vehicles and the costs of daily routes of these vehicles are minimized. In this study, a mathematical model is introduced and a 4-step solution development heuristic has been built. In the first stage of the heuristic, by modifying the Fisher and Jaikumar clustering algorithm, a mathematical sub-model which takes the amount of waste of farms, the number of farms and their closeness to each other as objective function is formed. With the cluster information obtained from the first model, the Travelling Salesman Problem was solved for each cluster in the second stage. In the third phase, a sub-model which minimizes the number of vehicles considering the distances between the farms, working hours and operational time constraints is developed in the light of the outputs obtained from the first two phases. At the last stage, Very Large Scale Neighborhood Search algorithm is developed. The heuristic has reduced the total path near 10% in the first stage. After the VLSN Search, an additional 7% decrease is observed. Lastly, 30% reduction is achieved in the number of vehicles. As a result of these improvements, it is predicted that approximately 573.944 Turkish Liras would be gained annually from the cost of labor, vehicle and fuel.
