This paper aimed to propose a decision-making model for optimal management at Port Company of Soyo in Angola. The model based on quali-quantitative analysis approach of management and on hybridization of the rational, administrative and political decision models according to data analysis collected from two questionnaires applied to a sample of 42 common workers and 15 members of management team, taking to account the company’s results during the period 2009 to 2018. The company performances observed a decreasing trend of 127.7% on the annual net results. The proposed hybrid model included annual forecasting models for income and costs and a deterministic optimization model of gross profit until 2028 on the current scenario. The model validation shows the increasement of 99.1% on the company’s net profit.
