An Optimal Solution for Locating Tide Station Locations in Internal Gulf of Thailand by Using Location Allocation models (P – median)

Abstract

The aim of this study is to utilize a location allocation model (P-median) to determine the optimal locations for tide stations in the Historic Bay of Thailand, based on three factors: variation in tide elevation, the number of ports, and population density. Two scenarios were considered: (1) adding new tide stations while retaining all existing ones; and (2) not retaining the existing tide stations but instead rearranging and adding new stations. The results indicated that the second scenario—rearranging the tide stations and adding new ones without retaining the existing stations—provides a more optimal long-term solution in terms of budget efficiency and coverage. This study can serve as a guideline for hydrographic offices to adopt when planning the construction of tide stations.
