Using Analytic Hierarchy Process and Technique for Order of Preference by Similarity to Ideal Solution for Multi-Criteria Decision-Making Approach in Evaluating Science High School Campus Sites

The study aims to evaluate the Philippine Science High School (PSHS) campus site using a multi-criteria decision-making approach, particularly the Analytic Hierarchy Process (AHP) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). The criteria used to determine the campus sites are the following: the existence of a PSHS campus in the region, location and environment, topography, size, accessibility, Internet access, and geologic hazard. Using descriptive analytics, data indicate that PSHS can only accommodate 0.044% of the total population belonging to the 10–19-year-old age range due to the limitation in campus capacity. Results also show that spillovers from the National Capital Region were enrolled in almost all PSHS regional campuses, except for PSHS-Central Mindanao Campus and PSHS-Southern Mindanao Campus, as 14% of the total number of students in the last 10 years came from this region. Upon evaluation of the results, the venue of the future PSHS campus should be evaluated independently per region based on the following relative weights of 20% for location and environment, 18% for geologic hazard, 17% for accessibility, 16% for internet access, 15% for size, and 14% for topography, which can be attributed mainly to the current location and needs of the PSHS campuses. Based on the Performance Score, using TOPSIS, the alternatives were ranked and a northern part campus location (PSHS-Ilocos Region Campus - 0.6647) was ranked as the best alternative having acquired the maximum value.
