    Application of Multi Criteria Decision Making for the Selection of Optimal Solid Wood Fuel Supply
    (Faculty of Electrical Engineering, University of East Sarajevo, 2018) Vasković, Srđan; Gvero, Petar; Batinić, Krsto; Halilović, Velid; Medaković, Vlado; Musić, Jusuf
    Production of solid fuels from wooden biomass is defined with appropriate energy chain of supply. The notion of energy chain concept has been defined as the trajectory of energy transformations from the fuel source or energy sources to useful energy form to end users. Supply chain for production solid fuels from wooden biomass is also energy chain with high importance in biomass energy planning. In this paper, base for testing and research is developed mathematical model in previous published paper with preliminary note titled as “Multi-Criteria Optimization Concept for the Selection of Optimal Solid Fuels Supply Chain from Wooden Biomass“ at Croatian Journal of Forest Engineering. Three supply chains have been included in comparison: production of wood chips at the terminal – variant 1, production of pellet – variant 2 and production of wood chips by means of a mobile chipper in a forest – variant 3. The VIKOR methodology is used for total ranking all mentioned chains. Real input data have been used for mathematical calculation correspond to Bosnia and Herzegovina conditions.

    Multi-Criteria Optimization Concept for the Selection of Optimal Solid Fuels Supply Chain from Wooden Biomass
    (Sveučilište u Zagrebu Fakultet šumarstva i drvne tehnologi, 2015) Vasković, Srđan; Halilović, Velid; Gvero, Petar; Medaković, Vlado; Musić, Jusuf
    Production of solid fuels from wooden biomass is defined with appropriate energy chain of supply. Production procedure of solid fuels from wooden biomass, starting with technology for gathering wood residues and residues from logging up by the system of fuel production (system for milling, crushing, chopping, drying and pressing of wood residues), represents the energy chain of supply of solid fuel from biomass. Every single energy chain of supply and production of certain form of solid fuel from wooden biomass can be uniquely defined with three general criteria. These criteria are: energy efficiency of production, economy of production and environmental criteria. Efficiency of production is the relation of overall energy consumption per 1 kWh of heating value of produced fuel. When we talk about the economical aspect of production of solid fuels we take into account all production costs per 1 kWh of heating value of biofuel produced. Forest biomass is scattered and the need for its collection and transport require certain consumption of fossil fuel. Consumption of fossil fuel is needed to run mechanization to collect, transport and prepare biomass. Consumption of fossil fuels causes the emission of GHG. Ecological criteria for the estimation of production process of bio energy can be defined as emission of GHG per 1 kWh of heating value of produced fuel. Besides general criteria to estimate the quality of production of energy from biomass, there are specific criteria. Specific criteria regarding several characteristics are tightly related to applied technologies, potentials and barriers during the use of biomass. This paper analyzes only specific investment in selected chain of energy supply. The paper mathematically describes four characteristic cases of solid biofuel production from wooden biomass. These cases are: production of wooden chips from forest biomass with mobile chipper, production of wooden chips from wooden residues transported from sawmill to processing terminal, production of wooden briquette from mill residues transported into briquette factory, production of wooden pellet from mill residues transported into pellet factory. For overall ranking of energy chain of wooden biomass supply and selection of optimum variant, multicriteria optimization and VIKOR method is used.

    POSTROJENJA ZA PROIZVODNJU SEKUNDARNIH ENERGENATA OD DRVNOG OTPADA – KAPACITETI I MOGUĆNOSTI NA PODRUČJU ZENIČKO – DOBOJSKOG KANTONA
    (Mašinski fakultet Istočno Sarajevo, Univerzitet u Istočnom Sarajevu, 2018) Halilović, Velid; Vasković, Srđan; Musić, Jusuf; Knežević, Jelena; Balić, Besim; Softić, Jasmin; Golubović, Dušan; Košarac, Aleksandar; Jeremić, Dejan
    Utvrđivanje kapaciteta proizvodnje sekundarnih energenata na području Zeničko-dobojskog kantona pruža važno uporište za detaljnije i racionalnije planiranje korištenja drvnog otpada iz različitih izvora, koji nastaje na navedenom području. U ovom radu istražene su i prikazane prednosti korištenja sekundarnih energenata u odnosu na fosilna goriva, i to sa ekonomskog, ekološkog i energetskog aspekta. U cilju prikupljanja podataka kreiran je anketni upitnik sa konkretnim pitanjima vezanim za proizvodnju sekundarnih energenata na koja su odgovore dali odgovorna lica subjekata koji su obuhvaćeni istraživanjem. Rezultati rada pokazuju da potencijal proizvodnje sekundarnih energenata na području Zeničko-dobojskog kantona ne koristi se na zadovoljavajućem nivou. Maksimalni kapaciteti proizvodnje se ni približno ne ostvaruju. Zaključci govore da je proizvodnja cijepanog drveta tek 49% od maksimalnog kapaciteta, peleta i briketa oko 60%.
