The Data Warehouse Institute is a great source for BI and data warehouse as well as analytics. The website has great articles, whitepapers, offers certification and education and organizes one of the best events in these areas. I have been following it for some time and I do recommend it for any professional.
Recently the website published a great article about the use of simulation in an organization - Use Simulation to Make an Impact. It covers the applications, recommends team structure and environment for proper and beneficial simulation. I like the clear structure and extensive coverage despite the small size. Enjoy!
