  2. My Background • B.A. degree in Math from UNC-Chapel Hill • M.S., Ph.D. degrees in Operations Research from N.C. State • Internship positions at Nortel and the EPA • Before SAS, was a Postdoc at SAMSI and worked as a Senior Research Scientist at the Virginia Modeling, Analysis, and Simulation Center

  3. About SAS • Founded in 1976 • SAS is the world’s largest privately held software company • 425 offices worldwide • 10,026 total employees • World Headquarters (Cary,NC): 4,154 employees • Customers in 110 different countries • 40,000 business/government customer sites more than 2,200 university sites

  4. SAS Analytics • Statistics • Data and Text Mining • Forecasting • Econometrics • Quality Improvement • Operations Research

  5. Operations Research: What Is It? • Webster:“the application of scientific and esp. mathematical methods to the study and analysis of problems involving complex systems (as firm management, economic planning, and the waging of war)” • Translation:“a set of tools for modeling real-world situations in order to learn more about them and make better decisions.” • Translation:“structured, repeatable methods for answering critical enterprise planning questions.”

  6. Operations Research and SAS/OR: Types of Models Available • Mathematical Programming • Achieve objective, satisfy constraints • Linear, integer, mixed-integer, nonlinear • General: LP, INTPOINT, and NLP procedures • Specialized: NETFLOW procedure • New: OPTMODEL, OPTLP, OPTQP procedures • Project Management • Satisfy constraints, generate possible schedule(s) • Scheduling: CPM, PM procedures • Display: GANTT, NETDRAW, PM procedures • New: CLP procedure

  7. Operations Research and SAS/OR: Types of Models Available • Decision Analysis • Sequence of decisions with uncertain results • Goal is to devise an optimal decision-making strategy • Interactive modeling: DTREE procedure • Discrete Event Simulation • Observe system performance, test alternative configurations • Significant non-deterministic elements in the system • GUI-based modeling and simulation: QSIM • New: Simulation Studio
