SAS Simulation Studio 13.1, a component of SAS/OR 13.1 for Windows environments, makes several enhancements to its graphical discrete-event simulation modeling and analysis interface. You can now specify a custom image to replace the default icon for any block instance; the new Visual tab on each block’s Block Properties dialog box enables you to specify a custom image and customize the block label. The Simulation Clock display has been augmented to graphically indicate the status of a model (running, paused, or stopped/completed).

The Definition view for a Submodel window adds its own block template, which appears when you place the cursor over a small image of the template near the top of the Submodel window. This feature makes it easier for you to add blocks to the definition of a submodel. In SAS Simulation Studio 13.1 it is also easier for you to edit expressions by using a dedicated Edit Expressions window. This window opens from many Block Properties dialog boxes for blocks in which you can specify expressions such as attribute rules. In addition, the calculation of statistics in the Resource Stats Collector block has been improved and expanded. Lastly, SAS Simulation Studio 13.1 streamlines the method for specifying a DataStreamDescription factor or an InStreamPolicy port value for a Numeric Source block in order to control the probability distribution that is sampled in the block.
