Sokolov M. Development of method of forming ship's cargo program with the use of imitation modelling

Principle of creation of method of synthesis of the loading program of ship, which uses the before formed database, is shown in the work. The general view of dependences of parameters of nautical safety from basic data is considered. The order of calculation of parameters of seaworthiness of ship is described. Formalization of ship's loading process is considered as multidimensional process. Analytical dependences that allow to define the scope values of parameters of great number of possible strategies of conducting of operations. It is shown in dissertation, that an optimization task is the task of the linear programming, because having a special purpose function determining the criterion of optimum, and limitations of task are linear dependences. For the decision of optimization task simplex-method and optimum decision is used is arrived at in one of extreme points. In this connection an optimum is searched in the eventual number of angular points of decision space. The record of standard task as matrix equalization is resulted. A situation is considered, when the load of ship is produced in a few stages and procedure of optimization of each stages of conducting of load of ship taking into account the requirements of stability and general longitudinal durability is shown. The results of imitation modelling of method of synthesis of the loading program of ship with the use of initial database are resulted in work. The imitation of the module of input of descriptions the cargo, module of indication of information by recommendations of cargo compartments and module of placing of loads in holds, ballast and stores in tanks with the indication of parameters of seaworthiness of ship is resulted. For the design the database of the m/v "Yon" is used. The input of basic transport characteristics of various types of cargo is considered. By separate module it is possible to obtain information about the parameters of cargo compartments. The module of placing of loads in holds is considered, ballast and stores in tanks with the calculation of parameters of ship's seaworthiness, which foresees the choice of type of load with the set amount and hold, where a load is placed. The results of imitation modelling is optimization of loading process of bulker "Yon".
