This book is useful to learners and instructors who wish to appreciate system dynamics modelling in the construction industry. It helps you look at different options and guides you on choosing the best. I have studied the dynamics of economic systems, providing new insights into the cycles and feedback loops in economic systems.The modeling approach focuses upon an understanding of feedback and feed forward relationships, and the model construction requires the analyst to construct the relationships between the various state variables and rate variables (flows). Several techniques are currently employed by the construction industry to quantify the impacts of changes and system dynamics is one of them. This is the first edition and am hoping that in the near future i will releasing the second edition.
