This book is the fastest way to learn the use of Vensim.
The book allows the reader to acquire step-by-step in a time-efficient and uncomplicated the knowledge in the formation and construction of dynamic models using Vensim. Many times, the models are performed with minimal current data and very few historical data, the simulation models that the student will design in this course accommodate these analyses, with the construction of realistic hypotheses and elaborate behavior models. That's done with the help of software Vensim that helps the construction of the models as well as performing model simulations.
At the end of the book, the reader is able to:
- Describe the components of a complex system.
- Diagnose the natural evolution of the system under analysis.
- Create a model of the system and present it using the simulation software.
- Carry out simulations with the model, in order to predict the behavior of the system.
The content of this book can be applied in many areas. In the business world, these topics are mainly used to address issues related to Strategic Planning, Business Planning, Leadership Development, Strategic Marketing and Sales, Organization Redesign, Process Improvement, Implementation of operational plans. In general to build and sustain high performance over the long term, and ensure successful implementation of changes. In the academic world, these topics may be used to develop Final Projects or Doctorate, theses on diverse subjects.
