SIMSCRIPT III Release 4.0 May 23th , 20161. Introduction SIMSCRIPT III Release 4 is CACI’s forth release of a new modular object-oriented system for designing and building both discrete and combined discrete/continuous simulations. It contains excellent object-oriented graphics for building a GUI, visual presentation of results, and both 2-D and 3-D animation. Included is SimStudio, GUI/project based development environment for building simulation applications, and runtime reusable libraries. SimStudio also contains a comprehensive class-browser feature, to enable easier inspection and navigation of large simulation models. SIMSCRIPT III Release 4 supports DataBase Connection (SDBC) which provides APIs for database connectivity based on Open DataBase Connection (ODBC) with any database on the market. SIMSCRIPT III Release 4 also supports the unique feature Check-Point/Restart, which facilitates easy creation of “What-if” scenarios mostly used in live, simulation-based training-exercises and studies. In analytical models especially in situations where a large amount of input data is needed for a particular initial simulation scenario, this feature can be used to automatically populate the data base creating the initial scenario for further analysis. SIMSCRIPT III Release 4 includes SIMSCRIPT Business-Rules Interpreter which facilitates easy creation of pre-programmed missions for simulated units and operations during model execution without a need for model source code modifications. In complex logistics analytical simulations, user can change business rules during run-rime, introducing new business rules in certain decision points, experimenting with different what-if scenarios without changing the simulation model. SIMSCRIPT III Example programs like graph_edit can be used as a jumpstart for building simulation tools for modeling and simulation of factory production processes, network topology for telecommunication networks performance analysis and optimization, etc SIMSCRIPT III facilitates creation of Reusable libraries which can be used for fast prototyping simulation models in certain application areas. Both, Graph-edit and SIMSCRIPT Business-Rules Interpreter are packaged as SIMSCRIPT reusable libraries (subsystems). Graph_edit reusable library can speed-up building network topology in network analysis tools or it can also be used for building factory layout simulations, building input scenarios for war-gaming etc. Business Rules reusable library can speed-up adding business rules to Business process simulations, logistics simulations, transportation, war-gaming etc. 2. SIMSCRIPT III Release 4 New Enhancements: The following new enhancements are supported in Release 4:
2.1. Checkpoint/Restart Checkpoint / Restore – unique SIMSCRIPT capability is now supported on both 64 bit LINUX and 64 bit WINDOWS platforms. Examples of checkpoint / restore are found in “ 2.2 SIMSCRIPT III Compiler Enhancements – smart build The SIMSCRIPT III compiler now includes a new “smart” build option “-j”. When applied, only those files specified that are out of date or have changed will be compiled. Dependency checking is performed – files that are in some way dependent on modified files (such as a public preamble) will be recompiled. When the “-j” option is used, all source files in the project must be specified on the command line. Not yet supported for SimStudio. The option will be utilized by the SIMSCRIPT III Eclipse workbench as soon as it becomes available. 2.3 SIMSCRIPT III Debugger Enhancements Printing value of an object attribute When using the SIMSCRIPT debugger and stopped in a object method, the user can now print the value of an object attribute of this method’s base class without specifying the name of the class. For example, assume that the attribute “current_fuel_level” belongs to a base class of the class called “destroyer” and “refuel” is an method of the class “destroyer”: SimDebug> br destroyer’refuel SimDebug> r BREAK: User breakpoint
# 156 process method destroyer’refuel SimDebug> pv current_fuel_level current_fuel_level = 1234 Handling Expressions The SIMSCRIPT III debugger now supports handling of expressions when referring to an object attribute, class variable, entity attribute, global or local variable value that needs to be inspected or assigned. This affects the command “PV” (print value), “FP” (follow pointer), and “SV” (set value). The “syntax” for these expressions is identical to that used in SIMSCRIPT III. Specification of array attributes and variables is supported. Syntax errors are detected and reported if the user does not form the expression correctly. SimDebug> fp destroyers(2) SimDebug> pv fuel(destroyer(the_navy)(2))
Simdebug> br MyRoutine if n.link_set(root_node(the_graph)) <> 0 2.4 SimGraphics performance improvements
2.5 New Simple Audio Capability Simple audio capabilitiy was added to SIMSCRIPT III via the new subsystem “audio.m”. The public preamble is found in the 2.6 Example programs - reorganized SIMSCRIPT example programs included in Release 4 are located in
New and enhanced example programs The “network editor” library and 2 example programs are added to example program(s) for the new graphedit library. The programs are added to ‘examples\demo\network_editor’ and are:
Enhanced AIRPORT demo model The 3d version of the “airport” demo (found in Enhanced RADAR demo model A new demo was written that is a variation of the existing “radar” program. It is called the “radar scenario builder” and is found in New SIMSCRIPT II.5 programs:
2.7. Run-time environment for deployment of Simgraphics programs A new utility called "DeploySG.bat" in %SIMHOME%/bin was added that when executed creates a runtime environment for simgraphics programs. When the utility is run from the program's "executable" folder, the environment is created an a special ".bat" file is generated to launch the executable. 2.8 SIMSCRIPT III programs automatically converted from MODSIM III Runtime environment for MODSIM-to-SIMSCRIPT converted programs is provided. The programs can be compiled and linked with this release using command-line scripts as well as Simstudio. It includes:
When compiling a converted MODSIM program, the “defm” folder must be included in the list of imported subsystems, (along with the “defs” folder).
NOTE: MODSIM to SIMSCRIPT converter program is NOT included in this release. If you need help in converting your existing MODSIM III models to SIMSCRIPT III please contact Ana Marjanski, Head of the Technical Department CACI Advanced Simulation Lab at Amarjanski@caci.com 3. 64-bit SIMSCRIPT Database Connection on Windows 7and 8 In order for SDBC example programs to work, on 64-bit Windows 7 and 8 platforms, the 64-bit data access libraries must be installed on the client machine. AccessDatabaseEngine_x64.exe can be found at microsoft.com site and must be installed to allow 64-bit SDBC program to communicate with data sources. As an alternative, the 64-bit version of Microsoft Office 2010 can be installed. 4. Supported Platforms SIMSCRIPT III Release 4.0 - Professional version is available on the following computer platforms:
Microsoft Visual Studio 2012 and 2013 are supported for both 32 and 64 bit "pro" versions of SIMSCRIPT. Visual Studio 2005, 2008 and 2010 are also still supported. SIMSCRIPT III Release 4.0 - Standard version is available on the following computer platforms:
SIMSCRIPT III Release 4.0 - Student version is available on the following computer platforms:
5. Recompilation and Modification Requirements SIMSCRIPT III Release 3 models have to be recompiled and re-linked with the new SIMSCRIPT III Release 4. SIMSCRIPT II.5 models have to be recompiled and re-linked with the new SIMSCRIPT III Release 4 using “–e” compatibility switch. 6. Installation Procedures for Microsoft Windows Users SIMSCRIPT III can be installed under a single arbitrary directory without system administrator privileges. The installation procedure is automatic and very simple. The “SIMHOME” environment variables is registered automatically during installation and SimStudio is ready to use. Also, a desktop shortcut is automatically created during installation that launches the SIMSCRIPT III command line interface window. This window can be used to launch the SIMSCRIPT III compiler and other tools. Another desktop shortcut is added that will launch SimStudio. NOTE: These shortcuts assign environment variables that are needed to build SIMSCRIPT III programs. Programs such as “simc”, “simld”, “simgld” … should only be invoked through the command window created by the shortcut. 7. On-Line Documentation SIMSCRIPT III Release 4.0 is supported by the following documentation which describes new object-oriented features, modularity and object–oriented Simulation Graphics:
Since SIMSCRIPT III is a superset of SIMSCRIPT II.5 All on-line SIMSCRIPT II.5 documentation is available and applicable to SIMSCRIPT III Release 4.0
SIMSCRIPT II.5 documents are in .PDF format and can be viewed by Acrobat Reader. 8. Notes for SIMSCRIPT II.5 users All SIMSCRIPT II.5 models need to be recompiled and re-linked with the SIMSCRIPT III release 4.0. Some complex SIMSCRIPT II.5 models which use non-standard SIMSCRIPT II.5 features will get a lot of compilation errors and warnings. It is recommended that models be modified to conform to the stronger type checking and syntax rules. Also models which use internal information about 32-bit headers of SIMSCRIPT II.5 dynamic arrays, entities and text variables will have to be modified to work properly with this release. Header sizes for both 32-bit and 64-bit SIMSCRIPT entities, object instances, arrays and text variables are all 16-bytes in length. Command-Line Interface – development commands for compilation and linking are the same as existing SIMSCRIPT II.5 commands: simc, simld, simgld etc To compile and link a SIMSCRIPT model use: simc –c *.sim simld –o model_name *.obj ‘’ for non-graphical models simgld –o model_name *.obj ‘’ for graphical models Compiler switches are the same as in the SIMSCRIPT II.5 with addition of the compatibility switch and selective suppression of compilation warnings. New additional compiler switches: –e provides compatibility with the SIMSCRIPT II.5 compiler, but it also excludes benefits of increased execution speed. -wn1, n2 provides capability of ignoring compilation warnings number n1, n2 Using these new compiler switches –e and –wn is not recommended. All compilation errors and warnings should be addressed and corrected in order to get full benefits of this new SIMSCRIPT III Release 4.0. Some SIMSCRIPT II.5 syntax is deprecated. Full list of deprecated functionalities along with the recommended code modifications is given in the Appendix , of this Release Notes. 9.

At this point the model state will be saved in a file with extension .chk, for example: SIMUxx.CHK An arbitrary number of checkpoints can be created during the same simulation run. Restart Restart the model from a specific checkpoint can be done using the following command line: modelname –cr –restore unit_number modelname –cr –restore 01 SIMSCRIPT debugger, Simdebug, should be used the same way as in models which do not use CR. Notes:
Example programs which illustrate usage of SIMSCRIPT III CR and CMR (Checkpoint/modify/Restart) are located in “ SIMSCRIPT III Business Rules Interpreter SIMSCRIPT Business-Rules Interpreter (SBR Interpreter) which facilitates easy creation of pre-programmed missions for simulated units and operations during model execution without a need for model source code modifications. In complex logistics analytical simulations, user can change business rules during run-rime, introducing new business rules in certain decision points, experimenting with different what-if scenarios. New subsystem for Simscript Business Rules called "sbr.m" is added to the SIMSCRIPTIII subsystems which can be imported and modified by the user. This subsystem allows business rules to be incorporated into a SIMSCRIPT III model. The public preamble file "sbr.m.sim" resides with the other public sub-systems preamble files in subdirectory " The “business_rules” folder was added to “examples/simple” folder. It contains a new example program for the SIMSCRIPT business rules ("SBR") called the “jobshop” model. The job_shop model is documented and can be loaded with SimStudio. For more information about the SIMSCRIPT Business Rules Interpreter please see document entitled SBR_Interpreter.pdf’ , added to %SIMHOME%/help which explains how to use the SIMSCRIPT III business rules interpreter. --------------------------- End of Appendix -------------------------------------- Download 49.43 Kb.
