In light of the growth in the numbers of maritime disasters during recent years, there is a growing interest in the evacuation of passengers and crew at sea, as documented in recent discussions at the Marine Safety Committee of the IMO. NATO has also developed analogous regulations as part of its Naval Ship Code. In this paper we propose a simplified evacuation model based on the shortest emergency evacuation time for emergency evacuation of a naval ship, which using the theory of mixed-integer linear program to solve navy ship evacuation problem. This evacuation planning model focused on the average evacuation time to travel through the ordered sequence of consecutive arcs by each group. In addition, the model revealed the amount of flow per time unit through the door. Secondly, we proposed a heuristic algorithm to produce sub-optimal evacuation plan. A numerical example is given at last. Results show that the model based on the theory of the mixed-integer linear program can provide more available evacuation solution for naval ship evacuation process.

This chapter examines two of the most important operational problems in seaport terminals, first, the berth allocation problem (BAP) which finds an optimal assignment of ships to the berths that minimise the total waiting time of all ships. Then we consider the ships containers to storage areas assignment problem (SSAP) which finds an allocation of ship containers to storage area that minimises the travelling time and containers dispersion. In the first step, a mixed integer linear program model is designed to address the BA problem with the aim of minimising the ships stay time in the port (known as the scheduling theory by the flow time). In a second step, the output of the first model is used in another mixed integer linear program model to solve the SSA problem with a view at reducing both travelling time and containers dispersion while satisfying storage capacities for the case where the containers of one ship can be partitioned into two different and consecutive storage area when needed. The experimental part is conducted on a real case, namely the Tunisian port of Radès.
