Thanks Alex for sending me the links. I am working in IT Service Management domain wherein there are a set of business processes at operation level. These processes must accomplish system level goals which are essentially business goals. No matter how efficient you make an individual process it alone can not achieve system level goals. Mere concatenation of business processes also will not help. We need to abstract a system out of these processes which connect to the process layer in a feedback relationship. System dynamics modeling could be one such approach. My question is  'how" to do it. How to integrate business process layer with a System dynamics model?

Hi Veerendra,

Any control theory basically applies to sets of differential equations, known as State-Space equations/model/method, derived by applying theoretical equations, curve fitting, interpolation, stochastic or some other methods from any empirical n-dimensional lookup table. Consequently, making these lookup table models out of your system is crucial. The variables could be as physical as time and temperature, to financial or process related, as long as ones depend/are related to the others. Then, you can apply software, such as Matlab/Simulink (trial versions are available) or dBASE, and some control theory knowledge for your non-linear MIMO (multi-input multi-output) system feedback control design.

References:

Brogan's "Modern Control Theory" (ISBN-13: 978-0135897638 ISBN-10: 0135897637 Edition: 3rd) is a good, basic feedback control design textbook reference for such systems.

Maybe, Anderson's "Business Economics and Finance with MATLAB, GIS, and Simulation Models" (ISBN: 1-58488-348-0 http://www.mathworks.com/support/books/book48464.html) will be more suitable for your problem.

However, a shortcut could be found in most of control design software "help" manuals or recorded Webinars, such as Mathworks' Matlab/Simulink library references (by the way, I am not associated with Mathworks' other than being longtime user of Matlab and Simulink for my electronic control designs, so that I am more familiar with this than other similar software):

Good luck with your design.
