CEO and President

As part of DAA's ongoing newsletter education program, I am pleased to announce the formalization of our Mechanical Engineering and General Software Support Services offering. www.DAAEngineering.com

As many of you know, an integral part of DAA's vision for Knowledge Based Engineering (KBE) and Web-based Design-to-Order™ Systems (DTO™) is the integration of high-end Mechanical Engineering and general Software Services. This unique offering is part of the backbone of DAA's approach to KBE and DTO™ automation.

DAA's unchanging perspective is the specification, development and delivery of production worthy KBE/DTO™ systems cannot be efficiently achieved without strong engineering consulting. This perspective is shared by many of DAA's customers including Dresser-Rand, Senior Aerospace, Delphi, NASA, GE, General Motors and many others.

In addition to providing engineering consulting as part of our KBE offering, DAA's Engineering Team has been continually retained for non-KBE services work. This work has always been a natural extension of our engineering team.

DAA Engineering Services customers have enjoyed the following benefits:

  • Very little or no training time
  • Zero risk
  • On-budget and on-time deliveries - always
  • The highest quality engineering staff
  • Use and management of offshore resources when appropriate
Please review our website at www.DAAEngineering.com. You may contact us at info@daaengineering.com for more information or for mechanical engineering or general software support services.

    Since the inception of modern KBE systems over 15 years ago, one lesson has been hard learned by many; KBE methodology is critical. KBE methodology refers to the following of a well defined KBE process, executed by the right people, as being indispensable to successful production deployment of KBE applications. The failure to follow a well developed KBE methodology always results in project failure to some degree.

    One of the most critical aspects of KBE methodology is proper business analysis as an integral, and indispensable, part of the KBE planning process. Proper business analysis, discernment of business needs, and the final translation of those needs into technological, KBE terms is requisite. Increasingly, the difficulty in conducting business analysis, needs discernment and technology translation, by off-shore consultants has become increasingly evident. The June 2004 issue of CFO Magazine categorizes these as types of tasks as "high risk" for off-shoring while, at the same time, outlines "low risk" tasks where off-shoring can be used effectively.

    Increasingly, off-shore suppliers are becoming trained in KBE technology. Over the past three years DAA has worked extensively with off-shore partners. We have had great success. These partnerships have lowered costs and in certain cases increased quality.

    In the area of KBE technology, off-shore resources have been shown to work well when used within the context of an on-shore, KBE methodology such as DTOPro™ as employed by DAA.


    Series: Technology Positioning - Knowledge Based Engineering vs. Traditional Technologies.

    What are some specific examples where KBE DTO Systems work well and Configurators struggle?

    In our continuing discussion regarding the differences between Traditional Configurators and Knowledge Based Design-To-Order systems we'll highlight some of the differences by taking a look at specific examples:

    1. Cooper Industries, Crouse-Hinds Division, Sign Configurator
    2. General Motors, Brake Hose Configurator.

    Crouse Hinds Airport Lighting Products has a Knowledge Based Sign Configurator that automates sign designs, proposals and manufacturing documentation. This system incorporates knowledge, rules and specifications that govern virtually every aspect of sign design, manufacturing, and installation; and the back-and-forth interaction between sales, engineering and the customer. DAA Knowledge Based Engineering (KBE) technology was chosen over a traditional Configurator because DAA's KBE technology handles:

    • Dynamic generation of geometry and drawings
    • Complex algorithmic logic regarding geometric relationships
    • A "rules in a bag" programming approach that allows for easy and quick "add-hock" rule changes without system re-write.
    Traditional Configurators can't handle dynamic generation of geometry or drawings and require procedural programming of rules. Through the use of KBE technology, Crouse-Hinds has been able achieve these deliverables and also deploy this system on their in-house sales computers and over the web to important customers. In addition, they have completely eliminating the need for engineering involvement in day-to-day sign configuration, drawing and quotation. They have also achieved an 86% efficiency increase over manual methods.

    General Motors consumes large amounts of engineering, drafting, manufacturing, prototyping and testing time designing brake hoses for their line of cars and trucks. In order to reduce cycle times and associated costs, a DAA Knowledge Based Configuration System was chosen. The following items were provided to GM that could not be delivered with a traditional product Configurator.
    • Complex geometric assembly and motion analysis of the suspension system.
    • Geometric interference analysis between the brake hose and the various suspension components.
    • Complex non-linear mathematical analysis predicting brake hose deformed geometry over the entire range of suspension motion.
    • Geometry (CAD) based inputs to the Brake Hose Configurator.
    In the GM system, as well as the Crouse-Hinds system, a Traditional Configurator would lack the capability to conduct the geometry based reasoning and logic required to solve these problems. In addition, the required drawing, CAD and graphical manufacturing outputs could note have been created as they require dynamic generation. KBE systems are the only class of systems that can dynamically generate geometry and drawing outputs.

    In our next newsletter we'll continue to explore the differences between Traditional Configurators and KBE systems in terms of how rules are loaded and maintained.


    Series: Knowledge Based Systems on the Web - Question 2 of 5 (More to come)

    Can I web-enable an existing Knowledge Based Engineering System?

    Yes! An entire host of legacy (pre-existing) systems can be web-enabled using DAA's Knowledge Server (KS). And you're not limited to just Knowledge Based Engineering systems, either. Enterprise and desktop systems can be web-enabled using KS as well. As long as a system has an Application Programming Interface (API), it can be web-enabled.

    Legacy systems such as Microsoft Office (Excel, Word, PowerPoint, etc.) can be web-enabled just as well as complex KBE models. These systems can also interact with each other and provide one another with data that may be required to finish an intricate design. DAA's Knowledge Server is a gateway between users, applications, and data.
    In the past, the web-enabling of desktop-based systems has proven problematic for many reasons:

    • Scalability - Only one user can use the system at a time.
    • Reliability - What happens when the computer hosting the system loses power? What if the system encounters a fatal error and shuts down?
    • Accountability and Security - How do you ensure only authorized users are allowed to access the system?
    DAA's Knowledge Server has a remedy for each of these concerns, and enables your system to be published reliably and securely over the web.

    Configurable Web User Interface for DTO Systems (Part 1 of 2 in the Series:)
    Computer
    What capabilities does the UI have?

    Standard Templates
    DAA has developed new "boilerplate templates" available for rapid development of web-based Knowledge Based Engineering systems. These templates include standard User Interface (UI) features such as radio buttons, drop-down boxes, multiple-select boxes, and text boxes. By utilizing our templates, we provide a robust user experience while maintaining a rapid development cycle.

    The standard templates are full featured and include automatic server and client side input validation. However, if the templates do not meet our customers' specific needs we can develop or work with our customer to integrate a more customized user experience.

    Customized User Interface With our custom UI option, any number of technologies can be employed to give users a richer interface experience. Rich media technologies such as Macromedia Flash can be integrated into the interface to provide advanced features that are not available using standard web controls.

    There is a tradeoff with this approach, however; the client requires more processing power and the user base may be limited to browsers that support the more advanced feature sets utilized by the feature rich content. Custom content also takes longer to develop than content that is delivered using a standard template.

    DAA offers the choice for the user experience: standard, customized standard, or a completely custom "look and feel." The UI is the gateway to reduced quote turn-around time, reduce design time, elimination (or drastic reduction) of engineering involvement in specials, customs and designed to order products, generation of immediate design documentation for customer approval, retention of engineering knowledge, reduction of errors, to name just a few of the benefits of a Knowledge Based Engineering System.

    Rules Separated from Graphics
    With traditional UI tools such as ASP or JSP, graphical controls and logic are integrated. This integration can result in large scale UI re-writes when either the logic or graphical controls are changed.

    DAA's new UI technology separates logic and graphical controls, thus eliminating the requirement for UI re-writes when logic or graphics changes are required. The result is lower cost to development, more flexibility and lower maintenance costs.
