A new method of system modeling

P were planning module Fig4Planmodule fan control module control module 524 by reading the path planning and operational planning documents, concurrency control of AUV's movement and operations, and get feedback after the AUV operations, for the next sensing data measurement modules do preparation. Figure 5 shows the control module of the model, in which, P. And P, respectively, the system reads the path planning and operations planning data, and read the planning documents indicates that the system T, T, said system controlling the motion of movement and operations, MP and MP, respectively, path planning documents and operational planning documents, MP says beat signal system, MP AUV system control actions that have feedback. 2.5AUV system model has been the object model, you can construct the system model of the AL a few, the system model shown in Figure 6. S = (0, R), 0 = {0,02,03,041, R = {(MP, G1, MP21), (MP23, G2, MP3I), (MPII, G3,[link widoczny dla zalogowanych], MP22), No. 5 Meng Wei, et al: A new modeling approach 45 ・, I / P, 1 elbow only MP4] Figure 5 Control Module Fig. 5ControlmoduleM only t (MPG3, MP32), (AG3, MPd2), (MP \G. that information back to the previous action next action, G that reads the database file, G, beat the system that sent signals, G and G, respectively, path planning and operational planning to read the file, G to read the new state that file. Basic OOPN model is a message by the library of the reach of the input Shu connection between them and related OOPN composed of the corresponding gate shown in Figure 6 MP library feedback feedback through G will be sent to MP: , MP .. the beat of the system signals are transmitted to the three modules of the MP, MP,[link widoczny dla zalogowanych], and MPNIP through the G-line data file passed to the MP MPMP and read through the G and G5 IVlP33 and NIP in the path planning documents and operational planning documents , MP, and MP by G connected to the new state of file transfer to the radio module,[link widoczny dla zalogowanych], while the beat clock signal is generated with the conclusion from the OOPN .3 in AuV system can be seen. It has the following characteristics: 1) system model can easily be refined or a higher level of abstraction, and can be layered, with good modularity 2) the internal structure of an object separated from the same external structure and improve the maintainability .3) Petri net model library can be the state of the object, condition, or some of the data correspond to the changes in the behavior of objects can be mapped and can be mapped to each other, easy to understand the system model .4) take into account the capacity of the formal system modeling and analysis capabilities bottom-up hierarchical, modular modeling .5) by adding object-oriented technology, spatial complexity can be reduced greatly saves storage space, reducing the \Petri Net-phase units knot. well positioned to meet the requirements of the system, the system has good modularity, easy to add and modify functions to accelerate the system development cycle.
