      Progress of modern areas of a science, engineering, technologies and biotechnologies, technologies of an environment depends on a level of theoretical and practical realization of methods of designing of the automated technical objects, technological plants and lines which are defined as Complex Dynamic Systems (CDS).

      Modeling CDS gets all a greater urgency. Multiprocessing systems are applied to realization of CDS-models, and all potential computing capacity of such system is used not completely. For achievement of greater efficiency of system developers of the parallel software solve a problem paralleling programs.

      In the time of parallel modeling of Network Dynamic Objects with the Distributed Parameters (NDODP) systems with a lot of the equations are solved. Thus there is a problem of distribution of computing loading between processes.

      The purposes of the master’s work are development and research of problem-oriented parallel modeling environment for object with distributed parameters.

      The tasks of target computer and developing are:

1. Analysis of virtual parallel simulation model first paralleling level.
2. Theoretical analysis of second paralleling level.
3. Analysis of target computers.
4. Implementation of second level.
5. Experimental research and comparison of results of experimental data with results of the theoretical analysis.

      Master’s work will consist of following sections:

• The Analysis of the works, devoted to development and application of parallel modeling environments. In this section the question of Dynamic Systems (DS) as objects of modeling will be considered, and are made demands to methods and ways of modeling DS. Modern ways of modeling DS, in particular language of modeling with use of the SISD-systems, existing parallel architecture, Grid-systems of access to the powerful distributed resources, as a condition and prospects of development parallel modeling environment are considered. Stages of construction of virtual models are developed.
• Object of research and its paralleling level. Short technical characteristics on Mine Ventilating Networks (MVN) will be resulted. The aerodynamic processes occurring in MVN, and as the mathematical equations describing ШВС as NDODP are considered. MIMD processes of the minimal granularity (the block diagram of the organization of data exchange between minimal granularity processes is resulted in figure 1.1.).

  Possible paralleling levels of Virtual Parallel Modeling Environment (VPME) MVN are characterized, the first paralleling level (a level of the minimal granularity) is in details analyzed and the second paralleling levels (a level of an element of a network).
• Theoretical analysis of VPME of the second paralleling level. In this section the basic criteria used of theoretical analysis of VPME will be formulated, the analysis for investigated paralleling levels is lead and drawn conclusions concerning efficiency of levels.
• Development of problem-oriented parallel modeling environment for objects with the distributed parameters. In this section process of development of the modeling environment, and as numerical methods which will be used for the decision of the mathematical equations will be described.
• Experimental research. In this section test MVN which calculation was spent at the theoretical analysis, will be modeled on the developed modeling environment. The data received as a result of modeling for the first and second paralleling level and data of the theoretical analysis will be subjected to the joint analysis and research.

      During performance of master’s works, creation of the modeling environment which can be used for research of the aerodynamic processes occurring in MVN is supposed. This modeling environment will put at disposal of the user the analysis with use of various numerical methods. Besides to the user will two paralleling levels, conclusions about which efficiency also grows out given master’s work are accessible.
