IE 621: Probability and Stochastic Models I

Prerequisite:  Instructor's permission


Models and techniques to deal with randomness that underlie many industrial and social systems. Emphasis on models, their properties and their applications (rather than proofs).


  • Introduction to Probability: conditional probability, independence, discrete random variables, expectation, moments, random vectors, joint and marginal distributions, continuous random variables, expectation, moments, joint and marginal densities, laws of large numbers.
  • Elementary stochastic processes: random walks, Markov chains: first step analysis, state classifications, invariant distributions, Finite state Markov chains, Chapman-Kolmogorov equations, limiting state probabilities, Stationary distributions. Memory-less property of exponential random variables and related models & examples, Poisson processes. Optional: basics of queuing theory, renewal theory, and applications.
