Consulting and software development areas:
Computer simulation of dynamic systems: Continuous, discrete and combined models. The models can be given by the customer or developed by the consultant. Main classes of simulated systems are:
Systems described by the differential equations
Signal flow graphs
Discrete systems like queuing and manufacturing.
Simulation of automatic control systems, both continuous and sampled-data.
Model development. Given an informal system description, the consultant proposes the mathematical or logical model specification and implements it on the computer.
Consulting in theory of modeling and simulation and control theory, including optimal control problems.
Software tools: Dr. Raczynski is the author of the PSM++ (new version of PASION) simulation system and distributes this tool (see the short summary below). Other tools are target custom simulation programs elaborated according to the particular needs of the end user. The new version of PSM++ is called Bluesss. It generates C++ source code.
C++ queuing code generator
Blues Simulation System is the C++ version of PSM++, it generates C++ source code

PSM++ is an object-oriented, Pascal-related simulation language. The language has a clear process/event structure and is equipped with appropriate environment. PSM++ translator generates Pascal source code that can be run using a Pascal compiler (this new version generates code compatible with the Borland's Delphi 3 or 4). The following features make PSM++ the most complete and versatile simulation tool.
Efficient scheduling and event queue management.
Inheritance mechanism, that permits to add new properties to old processes without intervening the source code of processes declared earlier.
State events. Discrete and continuous objects can run concurrently. The state events can be activated by continuous objects as well as by logical conditions changed by discrete objects.
The library of PSM++ predefined processes contains various frequently used processes, e.g. a rigid body dynamics, and several helpful processes that handle graphics and show simulation results.
Program generator for ODE (Ordinary differential equations) models DIFEQ.
Program generator for queuing models QMGW. This module includes graphical editor for queuing schemes, program and report generators.
Program generator for continuous processes FLOWD described by signal flow diagrams or block schemes.
Bond Graph editor and analyzer BONDW. This module includes a Bond graph editor and a program generator that creates source Pascal and PSM++ code for a given Bond graph model.
PSM++ Animator. Includes a Scenario and Icon Editor that permits to create 3D scenarios for animated simulation. The user creates the scenario and defines the possible routes for model components and the component icons. A simple calls to an animation procedure from the source program makes the icons move according to the simulated component activities.
VARAN: Post Mortem analyzer for stochastic (discrete and continuous) models. Shows variance, confidence intervals etc. as functions of time, particularly useful for the statistical analysis of transient processes.
Complex System Simulator CSS - new versatile PSM++ module. Very useful for combined systems, permits model coupling. Submodels of different types (queuing, continuous, etc.) run concurrently in the same simulation program. Needs no or very little programming. Generates PSM++ source code.
Object-oriented simulation offers great flexibility in model building. While coding directly in PSM++ language you can create complex models described in terms of processes and events, create the process instances (objects) and activate them.
The above figure shows a simple model of breaking the rack, where
each ball is a model object and moves according to its own rules,
receiving external forces from other objects, friction and the table
limits. This is only one of possible PSM++ applications. The whole
system can be used to simulate a great variety of systems, from
physical ones to queuing models, manufacturing, automatic control and
many others. See the PSM++ demo (can be downloaded from the complete
version of this summary) for the simulation run (animation) of
this model. Consult also the journal SIMULATION (November 1997, J. &
S. McLeod, "Simulation in the Service of Society") for a
PSM++ review. Implementation: the PSM++ system runs on the (minimum)
IBM 32-bits, 100 Mhz PC machine with SVGA color monitor (16 or
24-bits color), 16 Mb RAM.

Here you have some simulation links. First of all, note that the first one is a link to the Society for Computer Simulation Interational (SCS). This is the most important source of simulation knowledge and information about simulation journals and events (conferences, workshops etc.). There are also some pages of the McLeod Institute for Simulation Sciences (MISS, a part of the SCS), and other useful simulation links.
