Web-based CBR (case-based reasoning) as a tool with the application to tooling selection

Over the past few years, manufacturing companies have had to deal with an increasing demand for feature-rich products at low costs. The pressures exerted on their existing manufacturing processes have lead manufacturers to investigate internet-based solutions, in order to cope with growing competition. The decentralisation phenomenon also came up as a reason to implement networked-application, which has been the starting point for internet/intranet–based systems. Today, the availability of powerful and low cost 3D tools, database backend systems, along with web-based technologies, provides interesting opportunities to the manufacturing community, with solutions directly implementable at the core of their businesses and organisations. In this paper a web-based engineering approach is presented to developing a design support system using case-based reasoning (CBR) technology for helping in the decision-making process when choosing cutting tools. The system aims to provide on-line intelligent support for determining the most suitable configuration for turning operations, based on initial parameters and requirements for the cutting operation. The system also features a user-driven 3D turning simulator which allows testing the chosen insert for several turning operations. The system aims to be a useful e-manufacturing tool being able to quickly and responsively provide tooling data in a highly interactive way

IDL-XML based information sharing model for enterprise integration

CJM is a mechanized approach to problem solving in an enterprise. Its basis is intercommunication between information systems, in order to provide faster and more effective decision making process. These results help minimize human error, improve overall productivity and guarantee customer satisfaction. Most enterprises or corporations started implementing integration by adopting automated solutions in a particular process, department, or area, in isolation from the rest of the physical or intelligent process resulting in the incapability for systems and equipment to share information with each other and with other computer systems. The goal in a manufacturing environment is to have a set of systems that will interact seamlessly with each other within a heterogeneous object framework overcoming the many barriers (language, platforms, and even physical location) that do not grant information sharing. This study identifies the data needs of several information systems of a corporation and proposes a conceptual model to improve the information sharing process and thus Computer Integrated Manufacturing. The architecture proposed in this work provides a methodology for data storage, data retrieval, and data processing in order to provide integration at the enterprise level. There are four layers of interaction in the proposed IXA architecture. The name TXA (DDL - XML Architecture for Enterprise Integration) is derived from the standards and technologies used to define the layers and corresponding functions of each layer. The first layer addresses the systems and applications responsible for data manipulation. The second layer provides the interface definitions to facilitate the interaction between the applications on the first layer. The third layer is where data would be structured using XML to be stored and the fourth layer is a central repository and its database management system

Cost Estimation in Initial Stages of Product Development – An Ontological Approach

Cost estimation in the early stages of the product development process is fraught with uncertainties. The conceptual design is characterized by the absence of data, the most critical being costs. Decisions based on incorrect assumptions impact a project significantly and can increase unexpected costs in the future. As there are no structured means of obtaining costs in the conceptual phase, the reuse of data from past projects is an alternative discussed in the literature. Knowledge management approaches suggest a search for data in successful earlier projects. The use of ontologies has been regarded as an approach to capturing either knowledge stored in database or tacit knowledge. The proposed solution, in the form of an expert system built upon an ontological model, seeks to estimate costs based on costs in previous projects as well as expert tacit knowledge. The model is demonstrated by queries with needed functions and requirements. The ontological model searches the necessary information and generates a cost estimation. The present research project follows the methodological framework Design Science Research, presenting an overhead crane as a case study. The proposed approach has great potential in other industrial contexts as well

Business 2.0 : a novel model for delivery of business services

Web 2.0, regardless of the exact definition, has proven to bring about significant changes to the way the Internet was used. Evident by key innovations such as Wikipedia, FaceBook, YouTube, and Blog sites, these community-based Website in which contents are generated and consumed by the same group of users are changing the way businesses operate. Advertisements are no longer dasiaforcedpsila upon the viewers but are instead dasiaintelligentlypsila targeted based on the contents of interest. In this paper, we investigate the concept of Web 2.0 in the context of business entities. We asked if Web 2.0 concepts could potentially lead to a change of paradigm or the way businesses operate today. We conclude with a discussion of a Web 2.0 application we recently developed that we think is an indication that businesses will ultimately be affected by these community-based technologies; thus bringing about Business 2.0 - a paradigm for businesses to cooperate with one another to deliver improved products and services to their own customers.<br /

A Geographical Study on Solid Waste Disposal Management in Pyawbwe

Waste generation is increasing in Pyawbwe year by year because of increasing population, developing technologies and expanding economy. Physical factors describing the study area, both now and projected for the future, size, growth patterns, population, influence the economics of the proposed solid waste management systems. Solid wastes are collected under bell ringing system and communal dump collection system and are disposed at final landfilled waste disposal site located at Ingyin Kone cemetery. By using the Pearson's Product Movement Correlation Method, it is found that the correlation between the generation of solid from households and the collection of Municipal Department of Pyawbwe, there is high degree of positive correlation. Solid waste generation is depending upon the number of Tank Carriers and garbage trucks and it is also significantly related with households in Pyawbwe. These results indicate that it is necessary for the management of household solid wastes in Pyawbwe to take prior
