Goldratt's Theory of Constraints: Online Simulation

New from Levinson Productivity Systems, P.C. Downloadable Visual Basic program to simulate the matchsticks-and-dice exercise. Output is suitable for display on a computer projector.
This Java Script program simulates the matchstick experiment in Goldratt and Cox, The Goal. The experiment shows that a "balanced" production line is an illusion. The simulation shows how random variation in a production line with balanced capacity reduces its throughput below the theoretical rate, and causes inventory to collect in the factory.
