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
