Highlights of the changes include the following:

• The CLP procedure’s scheduling mode, which solves scheduling constraint satisfaction problems (CSPs), is now production. The CLP procedure now supports the specification of an objective function.

• The CPM procedure adds a control on the use of progress update information with resource-constrained schedules.

• The Microsoft Project conversion macro %SASTOMSP is production.

• The linear programming interior point solver adds an experimental crossover option that converts the optimal solution found to an optimal basic feasible solution.

• The linear programming solver adds a network simplex algorithm for problems with a dominant or embedded network structure.

• The nonlinear programming solver adds an active set solution algorithm and also adds a multistart capability.

• All optimization solvers (linear, mixed-integer linear, quadratic, and nonlinear) add performance improvements.

• SAS Simulation Studio adds Windows 64-bit support, closer integration with JMP, and several interface and technical enhancements.

More information about the changes and enhancements is provided in this chapter. Details can be found in the relevant volumes of the SAS/OR 9.3 User’s Guide and in the SAS Simulation Studio 1.6: User’s Guide.
