Knowledge Management – A Challenge For Smaller-Sized Enterprises

Today success and worth of a business depend more on its intellectual capital than on its physical. Therefore, Knowledge Management (KM) has become a critical input in the growth of SMEs. Globalization of supply chains, rapid technological advances, and superior returns on intellectual capital, growing importance of knowledge-intensive industries make KM a strategic tool in the growth and success of businesses. Access and integration of SMEs with regional, national and international supply chains require bridging the gaps between the requirements of supply chains and efficiency of SMEs' KM system besides their capability. KM process involves: knowledge capture, knowledge organizing and storage, distribution and sharing. Successful knowledge management results in the best possible means to apply and leverage the knowledge that has been captured, organized and stored, distributed and shared. It means that very little of the company's highly valued intellectual capital has escaped the knowledge management net. Virtually all the knowledge within the enterprise is harnessed, and will be used as part of the company's core business and competitive intelligence strategy. KM-enabled SMEs are essential for competitive and sustainable growth. In developing countries, a vast majority of SMEs are suffering from market failures due to insufficient provision for integrated, reliable, relevant and solution-oriented business information. SMEs need support for effective linking with global markets both for their inputs and outputs. Businesses leveraging knowledge resources can make decisions faster and closer to point of action. It is obvious that the smaller-sized company also needs to capture and intelligently exploit its knowledge. ... Read more

Dynamic Access And Emergence Mechanism For Collaborative Adaptive Systems From Agent’s Base

The main issue in human-machine interaction is obtained a "collaboration situation" between a human user and a computer system. The system must be attuned to the user, and the user to the system. "Good" conventions and guidelines shift the entire burden of adaptation to the user adoption, and the design restrictions that they impose are geared towards easing this task form the user to from specification and requirements of adoption by learning strategies [1].But providing such a list of technologies does not capture the essential feature of the intelligent interface research area: an intelligent interface must utilize technology to make an improvement: the resulting interface should be better than any other solution, not just different and technically more advanced but should be more capable on aspects of technology, eases of acceptance and flexible to move between environment: user modeling and natural language dialogue used to denote a scheme of that the system maintains, and adapts its behavior to interface access adoption by collaborative learning from system agent base and same time maintaining a system base for interface adoption between system to system environment and system to user access and process listing in selected services and grouping of protocol enabled agent base which maintain system environment access and learning base of adoption strategies. Development of adaptive systems reinforces the need to "know thy system environment ". The interface is set at design time but it is changeable for objective perspective. Adaptive systems may require more up-front environment analysis, since not only does the system designer need to know the user, that knowledge also must be embedded into the system ... Read more

Software Security: An Emerging Problem In Software Engineering

The objective of this research paper is to discuss the software security as a problem in software engineering. The solution of this problem leads to the new constructive approach to the modeling, specification and analysis of application specific security requirements. The approach is based on a framework we developed before for generating and resolving obstacles to requirements achievement. Our framework intentional obstacles set up by attackers to break security goals. Attack tree are derived systematically through anti-goal refinement until leaf nodes are reached that are software vulnerabilities observable by the attacker or anti-requirements implementable by this attacker. New security requirements are then obtained as countermeasures by application of threat resolution operators to the anti requirements and vulnerabilities revealed by the analysis. The paper also introduces formal epistemic specification constructs and patterns that may be used to support a formal derivation and analysis process. The method is illustrated on a web-based system for which subtle attacks have been reported recently. ... Read more
