The commercial products below are listed in alphabetical order. ACQUIRE is knowledge acquisition system and expert system shell. It is a complete development environment for building and maintaining knowledge-based applications. It provides a step-by-step methodology for knowledge engineering that allows the domain experts themselves to be directly involved in structuring and encoding the knowledge. (The direct involvement of the domain expert improves the quality, completeness and accuracy of acquired knowledge, lowers development and maintenance costs, and increases their control over the form of the software application.) Features include a structured approach to knowledge acquisition; a model of knowledge acquisition based on pattern recognition; knowledge represented as objects, production rules and decision tables; handling uncertainty by qualitative, non-numerical procedures; extremely thorough knowledge bases; sophisticated report writing facilities; and self documenting knowledge bases in a hypertext environment. ACQUIRE-SDK, their Software Development Kit, provides: callable libraries for MS-DOS,and SCO Unix; DLL's for Asmetrix TooBook, Windows, Windows NT, Windows 95 and Win 32; and custom controls for Visual Basic.

OPS83 was the first OPS-like language to provide this integration of rule bases with C. OPS83 supports Generalized Forward Chaining (GFC), a new control structure that permits rules to be more expressive; one GFC rule can replace several conventional flat rules. (Details and examples are available on request.) The current version of OPS83 uses the proprietary Rete II algorithm to enable it to handle large, complex rule sets efficiently. A multi-windowed, point-and-click development environment called the OPS83 Workbench is offered. OPS83 is available for DOS, OS/2, UNIX, VMS, and some proprietary operating systems.

It was designed to permit seamless integration of rules and objects into C programs. RAL is a superset of C. RAL rules can operate directly on the data types used by the C code in your application. RAL "understands" C type declarations, function prototypes, #define constants, etc. C expressions, statements, macros, function calls, etc. can be embedded directly in the rules. RAL has an open architecture that permits it to be used with any GUI builder, data base library, or other library that can be used with C. No bridges are required. For efficiency, RAL rules are compiled into C code. Charles Forgy, the inventor of Rete, has developed a more efficient match algorithm called Rete II for RAL. (Benchmark results are available on request.) A special version of the language, called RAL/RT, adds the features that are required for real-time expert systems. RAL and RAL/RT have a multi-windowed, point-and-click development environment called the RAL Workbench. RAL and RAL/RT are available for DOS, MS Windows, OS/2, and UNIX. License fees for development systems are available on request. There are no run-time fees charged for distributing applications developed using RAL.

With Rete++ the programmer can develop object hierarchies and instantiate, manipulate, and access them using either C++, the standard rule-based syntax, or C. Asserting and modifying the data that is considered by rules is done by creating a C++ instance and performing assignments to and accessing the member data of the instance. Rete++ automatically generates C++ class taxonomies. The C++ components of Rete++ applications use these generated classes directly or further subclass them as needed. The Rete++ inference engine automatically considers any instances of a generated class (or its subclasses) in the matching of rule conditions. C++ data types provided by Rete++ allow more flexible representation and automatic reasoning using standard C++ syntax without extraneous function calls. Rete++ automatically monitors changes to C++ objects without requiring programmers to explicitly code function calls. Rete++ is provided as a C++ class library. As such, it may be linked as part of your C++ application. You may completely embed Rete++, with or without its graphical development environment. Modules for developing Case Based Reasoning and integration with databases are available for Rete++ applications. Rete++ integrates a dependency based Truth Maintenance System to preserve logically sound and complete reasoning in spite of non-monotonicity. Multiple rulesets and agendas support modular development and cooperating expert systems. Rete++ has an advanced browser for rule based programming. The Rete++ windowing development environment monitors the knowledge base with multiple views that are all updated in real-time, allowing for debugging, browsing, the monitoring and setting of break points, and the tracing of rules, facts and goals. Rete++ 16 bit Windows Toolkit costs $999, Rete++ 32 bit Windows Toolkit costs $1,999, Rete++ OS/2 Toolkit costs $1,999, and Rete++ UNIX X/Motif Toolkit costs $2,999.

RTworks is a family of independent software modules developed for intelligent real-time data acquisition and monitoring, data analysis, message/data distribution, and message/data display. RTworks offers a number of sophisticated problem-solving strategies including knowledge-based systems, a point-and-click graphical user interface, temporal and statistical reasoning, and the ability to distribute an application over a heterogeneous network. Included with RTworks is a high-speed inference engine (RTie) which is used to analyze the data using objects, classes, procedures, and rules. The IE can perform trending, prediction and temporal reasoning of rapidly changing data. Displays can be built by non-programmers using a user-friendly DRAW program. More than 60 different formats are provided for displaying input data including strip charts, bar charts, control charts, dials, pie charts, and high-low graphs. Graphical objects can be tied to variables which dynamically control attributes such as color, scale, rotation, motion, animation, and more. RTworks runs in a client-server architecture in which the RTserver process intelligently distributes the application's messages and data to only the client prcoesses which need them. User-defined client processes can connect to the RTserver and send and receive messages with other processes in the application. Possible applications include process control, network monitoring, financial trading, and command and control. RTworks is available on a variety of Unix and VMS platforms under a floating license in which you pay only for the number of simultaneous users, and the software is not node-locked to a particular machine. Current RTworks customers include Lockheed, NASA, Dow Chemical, PG&E (Pacific, Gas, and Electric), SWIFT, Mazda, and NTT.

TechMate is a real life expert system designed to serve as a decision aid and productivity tool for maintenance engineers and technicians. TechMate minimizes the expertise required from the technician to troubleshoot and diagnose problems in even highly sophisticated and complex units. Oriented for the functional level, TechMate can troubleshoot units that contain analog, digital and mechanical modules in electronic, electro-optic, hydraulic, or mechanical systems and devices. TechMate is used in many fault isolation applications in field service, depot facilities, and production lines. Its learning algorithms make TechMate grow smarter with use. TechMate is a model-based system that derives its intelligence from universal built-in knowledge bases and inference mechanisms, and from specific knowledge about the UUT (Unit Under Test) supplied by the test designer. It generates diagnostic assessments from the equipments block diagram (which can be entered manually or imported electronically) and the characteristics of the symptoms and tests. It is also capable of diagnosing multiple faults. For a given set of symptoms and test results (including BIT results), TechMate's diagnostic algorithms rank candidate faulty modules by their likelihood of failure. It may also zoom in to further assess the fault likelihood of each individual sub-module. Next, TechMate identifies and evaluates the tests that may be used to isolate a fault, and proposes the most cost-efficient tests. The sequence of tests is dynamically reordered based on the symptoms, BIT and test responses, thereby eliminating redundant tests. TechMate provides on-line documentation of the device and its tests. It also includes a database tool for storing and retrieving administrative data and sharing it with commercial DBMS. TechMate can be interfaced with a wide variety of test instruments and ATE systems. TechMate runs on Microsoft Windows and on UNIX/X-Windows. TechMate customers include Texas Instruments, Northrop, Raytheon, Honeywell, BARCO, British Gas, Deutche Aerospace, and Siemens Plessey.

The YAPS library provides a CLOS class and appropriate methods which the programmer may mix into his/her own classes or use directly. Rules and facts about an instance are associated with the instance. Instead of one large knowledgebase with many rules which are hard to debug and maintain, the programmer creates smaller knowledge-bases which are modular and more efficient. The YAPS knowledge-bases can interact with and be controlled by the programmer's other modules, making hybrid systems straightforward. Introduced by Liz Allen at AAAI-83, YAPS is now available on Apple Macintosh, Sun3 and Sun4 (SPARC), DEC VAX under VMS and Ultrix, and 88Open platforms. On workstations, a single license costs $3995 and on the Macintosh (under Macintoch Common Lisp), it is $445. YAPS runs in most commercial Common Lisps including Allegro CL, Harlequin LispWorks, Lucid CL, IBUKI CL, and Macintosh Common Lisp. YAPS is also available for the TI Explorer and Symbolic Lisp Machines, and a Flavors version is available for Sun3 in Franz Lisp.
