    Business-to-business e-commerce: an innovative tool for food chain management

    Get PDF
    A supply chain is a network of facilities and distribution options that performs the functions of procurement of materials, transformation of these materials into intermediate and finished goods, and the distribution of the final goods to customers. The management of food chains, particular of fresh produce chains, need to achieve two goals: (a) create efficient physical flows of products by minimising logistics cost, and reducing lead times (b) run an effective value chain by safeguarding mutual gains for all members of the chain, building trust between suppliers and buyers and at the same time maintaining quality for end consumers. Food chain management was always at a loss for tools to leveraging its efforts on achieving value for chain members and eventually the end-consumers. Although food industry, both in USA and Europe, has experimented with various alternative solutions to this multimillion chain management, yet more can be expected. Business-to-business e-commerce (B2B) appears to be an innovative tool that meets the high standards of the industry and the potential growth. This study examines the uses of B2B in food industry to give chain management solutions. It reviews the uses of B2B and, in particular, highlights the applications of B2B by small agribusiness in order to forge their ring in food chains. It builds upon communication in supply chain. It describes contracting as an example how B2B e-commerce can advance supply activities and reports the development of a B2B olive oil supply chain application. It concludes that B2B can be a strong leverage for food chain management to achieve its goals and produce value for the members of the chain and the end consumers

    In ES implementations, process modelling is a critical and often overlooked activity. This paper proposes a framework for process modelling of ES. The four steps method involves: Current Situation Analysis, Business Process Improvements and Requirements, Gap Analysis, and To-be process to develop. Outputs of the methodology are an interdependent set of organizational and system proposed changes, and feedback loops to the ES vendors and to the strategy of the firm. In-depth case studies and extensive literature review provides methodological support. For practitioners, this study provides useful insights into one of the reasons by which companies could be frustrated with ES implementation.E-business, ERP

    CERN openlab Whitepaper on Future IT Challenges in Scientific Research

    Get PDF
    This whitepaper describes the major IT challenges in scientific research at CERN and several other European and international research laboratories and projects. Each challenge is exemplified through a set of concrete use cases drawn from the requirements of large-scale scientific programs. The paper is based on contributions from many researchers and IT experts of the participating laboratories and also input from the existing CERN openlab industrial sponsors. The views expressed in this document are those of the individual contributors and do not necessarily reflect the view of their organisations and/or affiliates

    Some Considerations about Modern Database Machines

    Get PDF
    Optimizing the two computing resources of any computing system - time and space - has al-ways been one of the priority objectives of any database. A current and effective solution in this respect is the computer database. Optimizing computer applications by means of database machines has been a steady preoccupation of researchers since the late seventies. Several information technologies have revolutionized the present information framework. Out of these, those which have brought a major contribution to the optimization of the databases are: efficient handling of large volumes of data (Data Warehouse, Data Mining, OLAP – On Line Analytical Processing), the improvement of DBMS – Database Management Systems facilities through the integration of the new technologies, the dramatic increase in computing power and the efficient use of it (computer networks, massive parallel computing, Grid Computing and so on). All these information technologies, and others, have favored the resumption of the research on database machines and the obtaining in the last few years of some very good practical results, as far as the optimization of the computing resources is concerned.Database Optimization, Database Machines, Data Warehouse, OLAP – On Line Analytical Processing, OLTP – On Line Transaction Processing, Parallel Processing
