In the Philippines, the healthcare delivery system has been described as somewhat operationally inefficient as it is consisting of government and private health, diagnostic, and treatment facilities spread unevenly across the archipelago. Thus, the objective of this study is to (1) assess the current basis of DOH and other regulatory agencies in building/expanding health facilities, (2) know the factors that have significant effect in the decision-making and (3) develop an integrated decision-making model that will make use of forecasting, simulation and optimization modeling approaches. The study proposed an integrated decision-making model that consists of three major categories to consider: volume drivers, health resources parameters and health facility requirements based on reviewed documents and articles. This model was developed to aid in decision- and policy-making related to health infrastructures.
