Mathematical Formulation of Management Targets

Abstract

Mathematical Formulation of Management Targets Overview of the Management TasksGenerally, maritime grids are designed to fulfil different missions, and during the missions, different management tasks should be achieved, which can be mainly classified as five types: (1) thermodynamic tasks; (2) environmental tasks; (3) economic tasks; (4) logistic tasks; (5) service tasks. Five types are grouped in Table 3.1.Chapter 1 has clarified the focus of this book: the long-term energy management of maritime grids, therefore the thermodynamic tasks are beyond the scope. In this chapter, six tasks are selected for their deep relationsip with the maritime grids. Navigation Tasks Typical CasesAs we all know, the ocean area covers more than 70 percent of our planet. In the following Fig. 3.1, we can see the main maritime shipping routes have connected the whole world. With the help of this meshed route grid and the main junctions, the bulk cargos, containers, and passengers are freely traveling by ships. Therefore, the primary management tasks for the maritime grids are the navigation tasks, which require the ships to arrive at the destination on time.There are many different types of navigation tasks, and in this section, three representative cases are to show the navigation tasks for ships: (1) ferry routes for a short two-way trips; (2) cruise routes for a long-distance traveling; (3) cargo/container ship route for inland/oversea trading.
