As avaliações de clientes, incluindo as avaliações do produto por estrelas, ajudam os clientes a saberem mais sobre o produto e a decidirem se é o produto certo para eles.
Para calcular a classificação geral por estrelas e o detalhamento percentual por estrelas, não usamos uma média simples. Em vez disso, nosso sistema considera coisas como o quão recente é uma avaliação e se o avaliador comprou o produto na Amazon. As avaliações também são analisadas para verificar a confiabilidade.
I should first state that I have an advanced degree in electrical engineering and have been using simulation techniques as part of formal design processes of complex system designs for years. Many of my colleagues that would be familiar with at least 3/4 of the book are trained or work in controls engineering , aerospace engineering and even very specifically the various systems engineering disciplines in missile system design and development (aerodynamics, guidance and navigation, seeker tracker development). For most of these people much of the material is introductory although there is always something to find in the breadth of topics. The primary part of the book that is probably not as well known to the commercial/DoD contractor side is the techniques used in DoD HAL simulations. This seems to be the author's primary professional experience and the book does provide some interesting insight into this very disciplined DoD approach to what is called Modeling and Simulation and the associated VV&A. The unfortunate part about this book is probably it's lack of an audience. Part of that problem is the strict focus on building simulations and quite a bit less (if any) on how you design and build systems using simulation. This leads to why although much of the material is still very relevant today, it lacks currency becuase little of the material is cast in the context of Model Based Systems Engineering (MBSE). Granted MBSE is a relatively newer term and the book was written in 2001, but but this is part of the reason it could use revision. With the lack of audience it probably will not happen which is unfortunate because Simulation engineering is becoming more and more an integral part of the systems engineering process at most organizations. There are not a lot of books focused on this. The engineers I mentioned before, just pick it up by osmosis although with modern software technologies and virtualization techniques teh newer incoming engineers are possibly better trained for this. With the widespread use of tool like MATLAB/Simulink, much of the material is somewhat irrelevant unless you are building a simulation (as in the author's case) from scratch. I only gave the book 3 stars because, as seen from the perspective of the end of 2016 mainly of a book written in 2001 it is pretty dated. However despite that, score there is one portion of the book tha thas really impressed m,me and motivated be to study much more. Most M&S and embedded types I know or know of do not really program using "classic" C++. They are generally either "C" or Matlab programmers. When I first look at the DSSL simulation language described in the book, I thought it was a nice to simulation language, similar to what I have used even back in the mid 1980's(albeit in FORTRAN and even earlier using punch cards). What I just realized is the the author has included an open source example of an Domain Specific Language(DSL) implemented in C++ Template classes way back in 2001! This is a real gem. Even if you are not going to use DSSL directly, the techniques used are applicable to any DSL implemented in "Modern" C++ with the STL template library using what is called "Generic Programming". These are very sophisticated techniques and ones not widely practiced and when there are it is mainly by advanced C++ programmers developing general software libraries. The DSSL have opened my eyes to a whole range of possibilities using C++ templates for M&S applications. This is the primary for this reason to still give a 4 out of 5 despite the rest of the dated material.
Simulation engineers seem to happen...rather than according to a plan. They build a model to solve a problem of theirs one day, and pretty soon other people are bringing them their problems to build models for.
This book is good for those of us who have followed that path. It links together those pieces that seem to float free in our knowledge bases, and helps to define the overall picture of doing a simulation and the topics that need to be addressed at a fundamental level when building a complex simulation.
If you want a beginning book...this ain't it. But if you have the need...then this is a good book to start with.
