Creating Synthetic Data with SAS/OR

A common barrier to quantitative research, especially in health and financial areas, is the inability to share sensitive data due to confidentiality and privacy. It can be difficult and time consuming to get permission to share the data, which means useful research is delayed or not even attempted. However, collaborators seeking

Finding the Beauty in Optimization Models - Visualizing MPS data sets

In 2013, Rick Wicklin blogged about visualizing matrices as heat maps using SAS/IML. That post reminded me that we had done a similar thing for the coefficient matrices in our optimization problems. In particular, we have developed some SAS macros to visualize the input data sets for the OPTLP (linear

Simulate to validate

The primary objective of many discrete-event simulation projects is system investigation. Output data from the simulation model are used to better understand the operation of the system (whether that system is real or theoretical), as well as to conduct various "what-if"-type analyses. However, I recently worked on another model
