AB This article deals with the Fleet Size and Mix Problem (FSMP). The main focus is to find the optimal fleet size and the type of ships used for the Indonesian Sea Tollway. A mathematical model for anticipating fleet demand under various circumstances has been built. The model primarily focuses on the strategic level, where the task is to minimize the total renting and operating/fuel costs for the vessels during the planning horizon. A deployment model was also generated to test the Fleet Size and Mix Model's accuracy, which comes under tactical planning. Fleet composition is given in tactical planning, and the goal is to find the precise utilization of the available ship to fulfil the transportation demand. Both FSM and FDM Models for our given problem are solved by integer programming on Python using Pandas, Numpy, and Pulp libraries. This article can be used as a guide to assist the Indonesian government in finding the exact fleet composition and routing.
