"Uncertainty, the sure sense that the ground is shifting at every step, is one of the marks of humanity! (Lewis Thomas) Random phenomena are an integral component of all realistic systems that our students will model and analyze. We must provide them with an adequate foundation in probability and statistics and then with the opportunity to utilize this knowledge in the context of solving OR problems."
