DSMAV: An improved solution for multi-attribute search based on load capacities
DHT (Distributed Hash Table) such as CHORD or PARTRY facilitates information searching in scalable systems. Two popular DHT-based approaches for range or multi-attribute search are to rely on attribute-value tree and a combination of attributes and values. However, tradeoff between a load balancing mechanism and query efficiency is a challenging task for such information searching systems. In this paper, we propose improved algorithms for a system called DSMAV in which information resources are distributed fairly among nodes and found based on multi-attribute queries in a small number of hop counts. Our system creates identifiers from resource names, each of which is a combination of attrib…
KPD: An Investigation into the Usability of Knowledge Portal in DMAIC Knowledge Management
Knowledge is considered as a resource that contributes an important role in the success of Six Sigma DMAIC methodology. However, knowledge resides brain of the individuals and exists in various forms and different places. This rise the problem of how to collect and share DMAIC knowledge everywhere all time. In this paper, we introduce a proposed Knowledge Portal named KPD that had been designed as a tool to manage DMAIC knowledge. Through the deployment of the Knowledge Portal, this paper aims at investigating its impacts on DMAIC execution based on experiments and appreciation of experts who are working in the areas of quality management and information technology. The results of the surve…
Developing Sustainable Processes through Knowledge Management
Sustainable development of a process depends on a harmonious association of three sustainable pillars: Economy, Society, and Environment. Yet, in case of DMAIC (Define-Measure-Analyze-Improve-Control) process, the combination is challenged by inefficient management of knowledge resource in the process. The potential economy resource is not preserved and renewed, and therefore influents on sustainability of the process. In this article, the authors present and discuss sustainable aspects of a knowledge management model for DMAIC in which knowledge resource is accumulated and reused efficiently. In particular, the key concepts of sustainable development are reviewed, a process of knowledge ma…
