The applications of knowledge-based systems technology to the domain of manufacturing design and production is known as Knowledge-based manufacturing. Thus it is the process of capturing the knowledge created in the product development. It is reused and enhanced with parameters and rules, integrating it with knowledge (design) templates. The design process is a knowledge-intensive activity and hence a great deal of the emphasis on knowledge-based engineering is on the use of knowledge-based technology to support computer-aided design (CAD). The knowledge-based techniques like knowledge management can be applied to the entire product lifecycle.
In knowledge-based systems, CAD domain has always made use of an early adopter of software-engineering techniques like object-orientation and rules. Knowledge-base manufacturing integrates these technologies with CAD and other traditional engineering software tools. Some of the benefits of Knowledge Based Engineering are a collaboration of the design team due to knowledge management, improved re-use of design artifacts and automation of major parts of the product lifecycle.
The technology of Knowledge engineering has been applied to the construction of tools which aims to provide support during the complicated process of manufacturing system design. The knowledge-based system is directed towards the analysis and redesigning of manufacturing systems on the basis of ‘controllability engineering’ method. Based on accumulated case experiences in the construction of the CENT system the approach used have been implemented on hypermedia tools. Building problems associated with the project are described, alternative solutions to the problems encountered are explored, the project’s current status is outlined, and the knowledge-based system’s use is detailed.
Knowledge based engineering is needed in several areas. Some of the areas where it is needed are –
· To create different platforms in intense pressure on product development cycle time and cost across various industries force them. Such platforms can formalize design and development processes, infuse organizational knowledge and best practices to automate them and reduce cycle time, cost, and design lapses.
· An ageing workforce, globally distributed systems and disparate design and manufacturing necessitate scientific capture and reuse of engineering knowledge.
Value proposition –
· Product knowledge configurations that capture information in a structured way, capture complex knowledge paths, and display resulting information to the user at every stage.
· To engage in product development on various KBE platforms state-of-the-art infrastructure and APIs and tools; including both commercial off-the-shelf and standalone platforms.
· Unified solutions for handling data and workflow – from concept to manufacturing, reducing cost and rework while improving time-to-market and product success rates.
· Knowledge-based engineering (KBE) maturity model for capability assessment and roadmap definition via organization-wide surveys and assessment
The transition to more knowledge-intensive and creative forms of economic activity across many sectors – is arguably more important than the first, and has been well documented both nationally and internationally. The economic theorists agree on the fact that the defining feature of capitalism at the start of the new millennium is the central importance of knowledge and learning in the creation of economic value and the determination of competitive success.
Some of the distinct dimensions of this transition are as follows:-
Firstly, on the basis of the qualitative characteristics of products (goods or services) and the ability to bring new or improved products to the marketplace quickly, competition between firms is increasingly being waged. Innovations in the production process are often just as important as innovations in the products themselves since they enable both the rapid shift to the creation of new products and the attainment of quality standards and performance that consumers now expect. Manufacturing firms that compete most successfully are no longer simply those that offer their product at the lowest price rather their ability to generate new products and process innovations in a timely and effective manner has become equally important. A large and growing proportion of innovation occurs through the interaction between economic actors between technology customers and technology producers or between partnering technology producers. These processes include actors like private firms of all sizes, colleges and universities, stand-alone research centres, technology transfer organizations, producers’ associations, unions and other institutions.
According to some well-respected analysts, the production of intangible assets and products has become central to regional and national economic vitality. It has assumed a position of increasing prominence in contemporary market economics as cultural products. These include activities as diverse as book and magazine publishing, television, film and video production, live and recorded music performance, multimedia, advertising, the design of clothing, footwear, jewellery, and furniture, live theatre, museums, and speciality foods and beverages.
According to criteria of time and cost, the designer is allowed to estimate manufacturability and also to explore different scenarios of parametric variation in the design. A case study has been presented to validate the system’s practicality and usefulness.
