The Affect Factors Identify the Design of Mathematical Models of Ship Routing and Scheduling

This paper has studied the models of ship routing and scheduling in maritime transport. The purpose of this research is to identify factors influencing the design of mathematical models of ship routing and scheduling (objective function, constraints and decision variables). These factors include the main fleet, ports and cargo, ship subplot length and width, fleet capacity, routes of transportation, bulk cargo, and so on. According to these factors models are designed for routing, as well as technical and physical obstacles and problems to be solved in the field of ship routing and scheduling.
