USE OF MULTICRITERIA DECISION MAKING METHODS FOR BIOMASS SELECTION IN FISCHER TROPSCH REACTORS

Proper choice of a fuel is an important task to fulfill the requirements for a bioreactor. The number of biomass fuel with different properties available to provide to a bioreactor is vast. However, application of efficiency and systematic mathematical approaches may achieve the evaluation. Multi-criteria decision making methods (MCDM) considers characteristic properties and qualitative criteria to assign importance to each alternative in order to select the best option. This research use MCDM for the selection of the fuel for a Fischer Tropsch reactor. The MCMD methods implemented are complex proportional assessment of alternatives with gray relations (COPRAS-G), operational competitiveness rating analysis (OCRA), a new additive ratio assessment (ARAS), Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) and SMART methods. The criteria weighting was performed by compromised weighting method composed of AHP (analytic hierarchy process) and Entropy methods. The results illustrated white grain appear has the best choice for a biomass fuel for the five MCMD.
