Abstract: The Philippine algae industry is a multi-billion dollar industry that requires restructuring to further gain global market share. Through the development of new algal bioproducts by strategically repositioning and enabling collaboration with existing industries, the Philippine algal industry aims to enhance its economic status. The decentralized locations of regions in the Philippines make it challenging to select a potential site for the industry. A decision support system is proposed to aid the industry for site selection that evaluates the different regions based on environmental impact, costs, social aspects, and industry presence. In addition, the site assessment considers the viewpoints of the various stakeholders to arrive at a sound and just decision. Thus, a fuzzy analytic hierarchy process (FAHP) method is employed to include the uncertainty in the subjectivity in the viewpoints of different stakeholders such as the academe, the government, and the industry. In addition, the FAHP approach is capable of combining both qualitative and quantitative data. The combined results revealed the level of importance of the main criteria with a combined weight of 43% for the environmental impact, 22% for the costs, 21% for the social aspects, and 14% for the industry presence. The disparity of priorities was observed among the stakeholders where the industry chose costs at 29% above other criteria when compared to the government and the academe which chose environmental impact at 44% and 40%, respectively, among other criteria. The highly preferred sites for the Philippine algae industry were Calabarzon, Northern Mindanao, Western Visayas, and Central Luzon due to the good potential labor force, presence of industries, and available resources in the regions. In order to achieve a harmonious prioritization of criteria among the stakeholders, policies on the encouragement of public investment on regions with marginal income must be considered.
