    Designing Traceability into Big Data Systems

    Full text link
    Providing an appropriate level of accessibility and traceability to data or process elements (so-called Items) in large volumes of data, often Cloud-resident, is an essential requirement in the Big Data era. Enterprise-wide data systems need to be designed from the outset to support usage of such Items across the spectrum of business use rather than from any specific application view. The design philosophy advocated in this paper is to drive the design process using a so-called description-driven approach which enriches models with meta-data and description and focuses the design process on Item re-use, thereby promoting traceability. Details are given of the description-driven design of big data systems at CERN, in health informatics and in business process management. Evidence is presented that the approach leads to design simplicity and consequent ease of management thanks to loose typing and the adoption of a unified approach to Item management and usage.Comment: 10 pages; 6 figures in Proceedings of the 5th Annual International Conference on ICT: Big Data, Cloud and Security (ICT-BDCS 2015), Singapore July 2015. arXiv admin note: text overlap with arXiv:1402.5764, arXiv:1402.575

    IDARTS – Towards intelligent data analysis and real-time supervision for industry 4.0

    The manufacturing industry represents a data rich environment, in which larger and larger volumes of data are constantly being generated by its processes. However, only a relatively small portion of it is actually taken advantage of by manufacturers. As such, the proposed Intelligent Data Analysis and Real-Time Supervision (IDARTS) framework presents the guidelines for the implementation of scalable, flexible and pluggable data analysis and real-time supervision systems for manufacturing environments. IDARTS is aligned with the current Industry 4.0 trend, being aimed at allowing manufacturers to translate their data into a business advantage through the integration of a Cyber-Physical System at the edge with cloud computing. It combines distributed data acquisition, machine learning and run-time reasoning to assist in fields such as predictive maintenance and quality control, reducing the impact of disruptive events in production.info:eu-repo/semantics/publishedVersio

    Costing Systems and the Spare Capacity Conundrum: Avoiding the Death Spiral

    No full text
    We hear how firms have to become lean, eliminate non-value added activities and strive to maximise asset utilisation, but there are inevitably firms with excess capacity that need relevant information to manage the cost of the under utilisation of resources. In this paper we question whether cost system designers have been taking appropriate account of the capacity issue, and ask whether the costing systems employed are sufficiently adaptable for fluctuating levels of capacity utilisation. We note that the capacity issue has received diminishing attention in the literature since the 1960s, and identify the dangers of not identifying the cost of spare capacity. We demonstrate how improper cost system design or usage can draw the firm into the death spiral. This danger not only exists when moving into a recession but also when recovering and resuming growth. We describe two cases that demonstrate potential pitfalls and alternative approaches to the capacity issue. The manufacturing case is an SME with a traditional costing system that was hindering management‟s pricing and product mix decisions. Fortunately the death spiral was avoided as it was recognised that significant spare capacity was distorting costs and prices when the firm continued to base overhead absorption on budgeted production volumes. The service case relates to a large financial services company that implemented a complex activity based costing system and gained a much greater understanding of resource consumption and capacity utilisation, and hence established more effective cost control in their back office operations

    Systematic analysis of needs and requirements for the design of smart manufacturing systems in SMEs☆

    Abstract With the increasing trend of the Fourth Industrial Revolution, also known as Industry 4.0 or smart manufacturing, many companies are now facing the challenge of implementing Industry 4.0 methods and technologies. This is a challenge especially for small and medium-sized enterprises, as they have neither sufficient human nor financial resources to deal with the topic sufficiently. However, since small and medium-sized enterprises form the backbone of the economy, it is particularly important to support these companies in the introduction of Industry 4.0 and to develop appropriate tools. This work is intended to fill this gap and to enhance research on Industry 4.0 for small and medium-sized enterprises by presenting an exploratory study that has been used to systematically analyze and evaluate the needs and translate them into a final list of (functional) requirements and constraints using axiomatic design as scientific approach
