Paper Title
LNG Portfolio Diversification Optimization Model of Thailand

Abstract
In this research, the mathematical model is constructed to analyze LNG supply of Thailand based on the available data in 2022 due to the increased reliance of importation of liquefied natural gas (LNG) for Thailand. We incorporate maritime risk and country risk into the model to find an optimal LNG supply diversification. The output exhibited that Malaysia, Brunei, and Australia are the main LNG exporters of Thailand. Moreover, when the demand increase, by the low competitiveness, the LNG from Qatar done not increase. In the study of effect of the risk, the output showed that due to the geographical closeness, the risk associated with shipping is ineffective to Thailand’s LNG supply. However, the risk connected to the political of suppliers is influenced by the decision of the supply. Furthermore, this study revealed the limitations of the research connected to the LNG supply of Thailand. Hence, the finding of this study not only present the alternative LNG import policy of Thailand but also consolidated Thailand’s energy security.
