What’s New in SAS/OR 14.1


Overview

SAS/OR 14.1 adds a number of new optimization capabilities that shorten optimization time, increase diagnostic capabilities, and make the software easier to use. Highlights include the following:

  • Several solvers improve their performance.

  • The concurrent FOR loop (the COFOR loop) in PROC OPTMODEL can run in distributed mode. Note: Distributed mode requires SAS High-Performance Optimization.

  • PROC OPTMODEL adds a profiler that tracks the amount of time spent in problem generation, presolve, and various stages of the solution process.

  • PROC OPTNET enables parallel computing, provides faster graph data input, and adds enhancements to three of its algorithms.

  • The quadratic and nonlinear solvers add irreducible infeasible set (IIS) diagnostics.

  • The decomposition algorithm expands the range of constraint matrix structures that it can detect automatically.

  • The CLP procedure adds more variable selection strategies.

SAS Simulation Studio 14.1, a component of SAS/OR 14.1 for Windows environments, adds features that improve the accuracy of your models and give you additional controls on model execution. Highlights include the following:

  • controls on the order in which dynamically created data input and output ports on blocks execute during the run of a model

  • centralized controls on the ranking of blocks in a model, which determines the order of execution for events that are scheduled for the same simulation clock time

  • expanded and improved controls on the allocation of resource units among resource entities when there is a scheduled adjustment

  • automatic launching of the SAS server on your local PC
