Gaychenia O. Development of method of forming of basic data of the computer cargo program of ship

Formalization of loading of ship is produced in work by the methods of theory of operations analysis. System description of cargo operations from positions of the system of acceptance of decisions is produced. Thus the examined system of acceptance of decisions behaves to the hierarchical systems which have three types of descriptions. To description of loading of ship the object-oriented approach, the objects "ship" are considered, "load" and "loaded ship, is applied". The great number of descriptions forming the database of the computer cargo program of ship is certain. It is shown that the database of the freight program of ship consists of four groups. Thus the first group of parameters contains descriptions of cargo apartments of ship. Descriptions of location of cargo apartments on a ship and descriptions of ship on the whole are the second group of parameters. Tabular dependences behave to the third group of parameters, which the indexes of sailing, stability and durability of ship are determined by. Parameters characterizing a type and placing of ship tanks are a final group. The imitation design of the modules is considered in dissertation, which the method of input of database of the cargo program of ship is realized by. To such modules attributed module of input of information about ship cargo apartments, module of data entry on a ship and module of data entry on the tanks of ship. It is shown that forming of database on the ship cargo apartments requires the input of information about their number, about that, input of type of hold (standard or complex). Five types of standard holds and four types complex are thus considered. The imitation design of the module of data entry on a ship is considered. It is shown that the input of length, width of ship, position of cargo apartments which are determined by their coordinates of centre of gravity is required. Besides it is necessary to enter displacement of ship empty, maximal displacement and co-ordinates of centre of gravity of ship empty. The imitation of the module of data entry on the tanks of ship is also considered. It is thus shown that it is necessary to enter the number of tanks of ship, after coordinate of centre of gravity of every tank, his sizes and type determining settings of tank.
