    Method for Business Process Management System Selection

    Get PDF
    In recent years business process management (BPM) and specifically information systems that support the analysis, design and execution of processes (also called business process management systems (BPMS)) are getting more attention. This has lead to an increase in research on BPM and BPMS. However the research on BPMS is mostly focused on the architecture of the system and how to implement such systems. How to select a BPM system that fits the strategy and goals of a specific organization is largely ignored. In this paper we present a BPMS selection method, which is based on research into the criteria that are important for organizations, which are going to implement a BPMS

    Modelling non-functional requirements

    Get PDF
    We present in this paper the language NoFun for stating component quality in the framework of the ISO/IEC quality standards. The language consists of three different parts. In the first one, software quality characteristics and attributes are defined, probably in a hierarchical manner. As part of this definition, abstract quality models can be formulated and further refined into more specialised ones. In the second part, values are assigned to component quality basic attributes. In the third one, quality requirements can be stated over components, both context-free (universal quality properties) and context-dependent (quality properties for a given framework-software domain, company, project, etc.). Last, we address to the translation of the language to UML, using its extension mechanisms for capturing the fundamental non-functional concepts.Peer ReviewedPostprint (author's final draft

    Integration of decision support systems to improve decision support performance

    Get PDF
    Decision support system (DSS) is a well-established research and development area. Traditional isolated, stand-alone DSS has been recently facing new challenges. In order to improve the performance of DSS to meet the challenges, research has been actively carried out to develop integrated decision support systems (IDSS). This paper reviews the current research efforts with regard to the development of IDSS. The focus of the paper is on the integration aspect for IDSS through multiple perspectives, and the technologies that support this integration. More than 100 papers and software systems are discussed. Current research efforts and the development status of IDSS are explained, compared and classified. In addition, future trends and challenges in integration are outlined. The paper concludes that by addressing integration, better support will be provided to decision makers, with the expectation of both better decisions and improved decision making processes

    Factors behind high cash usage in Hungary

    Get PDF
    This article summarises the findings of qualitative, in-depth interviews which aimed to explore the motivating factors behind domestic cash usage that generate the significantly higher cash volumes in Hungary than would ’normally’ be justified. In the opinion of the experts interviewed, cash usage may be facilitated by the intensive cash need of the hidden economy, the traditional cash-oriented behaviour of the public administration and a lack of trust in business-to-business transactions. This analysis primarily intends to capture certain trends, which may have temporarily changed in the wake of the economic crisis, but nevertheless span a number of years and the specific phenomena of which may be regarded as generally valid over the long term, apart from certain periodic effects.cash usage, hidden economy, tax avoidance, petty cash.

    Formalisation and use of competencies for industrial performance optimisation : a survey.

    Get PDF
    For many years, industrial performance has been implicitly considered as deriving from the optimisation of technological and material resources (machines, inventories,...), made possible by centralized organisations. The topical requirements for reactive and flexible industrial systems have progressively reintroduced the human workforce as the main source of industrial performance. Making this paradigm operational requires the identification and careful formalisation of the link between human resource and industrial performance, through concepts like skills, competencies or know-how. This paper provides a general survey of the formalisation and integration of competence-oriented concepts within enterprise information systems and decision systems, aiming at providing new methods and tools for performance management

    ERIGrid Holistic Test Description for Validating Cyber-Physical Energy Systems

    Get PDF
    Smart energy solutions aim to modify and optimise the operation of existing energy infrastructure. Such cyber-physical technology must be mature before deployment to the actual infrastructure, and competitive solutions will have to be compliant to standards still under development. Achieving this technology readiness and harmonisation requires reproducible experiments and appropriately realistic testing environments. Such testbeds for multi-domain cyber-physical experiments are complex in and of themselves. This work addresses a method for the scoping and design of experiments where both testbed and solution each require detailed expertise. This empirical work first revisited present test description approaches, developed a newdescription method for cyber-physical energy systems testing, and matured it by means of user involvement. The new Holistic Test Description (HTD) method facilitates the conception, deconstruction and reproduction of complex experimental designs in the domains of cyber-physical energy systems. This work develops the background and motivation, offers a guideline and examples to the proposed approach, and summarises experience from three years of its application.This work received funding in the European Community’s Horizon 2020 Program (H2020/2014–2020) under project “ERIGrid” (Grant Agreement No. 654113)

    Converting activities to processes for operational efficency improvement of a South African agricultural equipment manufacturer

    Get PDF
    Includes bibliographical references.South African agricultural equipment manufacturers face increasing pressures from global competition, in response they have resorted to manufacturing customised machinery in a bid to secure market share. This strategy, while successful, introduces a high degree of product variation and complexity - increasing strain on the manufacturing operation. In response to these strains, manufacturers are placing emphasis on finding new ways to improve manufacturing costs and accelerate product delivery. The objective of this dissertation is to assemble and sequence a practical framework, using commonly available (and established) tools and improvement methodologies, which will allow its user to effectively direct process oriented improvement through analysis and modification of the operations at the activity level. The framework seeks to achieve this by formalising the operating structures already present and subsequently modifying it, in a value driven manner, using lean principles and heuristic methods for the purposes of providing practical, easily integrate-able and affordable solutions aimed at promoting operational excellence while eliminating Lean wastages. Testing conducted showed that regardless of environment lean principles can be successfully adapted to produce significant reductions in lead time and gains in both product flow and overall quality

    Proposal for a conceptual model for a SaaS ERP using an Open Source System

    Enterprise Resources Planning (ERP) systems are considered an important part in business organizations but with increasing global competition companies tend to seek more agile solutions that enable cost reduction at the same time. The paradigm change of Software as a Service (SaaS) came to revolutionize the delivery of applications at reduced costs, reliability and scalability. The ERP Open Source working in SaaS model will allow companies to extract all the benefits associated with the technologies used. This thesis presents a model and framework for ERP Open Source SaaS. The model and the framework are based on the literature review, and both were evaluated by empirical work. To validate the model and framework it was implemented an Open Source ERP which is already at market adapted to Portuguese reality. As a second validation of the artifact, the ERP was used for learning purposes by university students. Here are also reported the results of their use experience. This research shows that exist localized Open Source Software ERP alternatives that can be employed in a cloud context by companies.Os sistemas Enterprise Resources Planning (ERP) são considerados uma parte importante nas organizações empresariais mas com o aumento da concorrência global as empresas tendem em procurar soluções mais ágeis que permitam ao mesmo tempo a redução de custos. O paradigma do Software como Serviço (SaaS) veio para revolucionar a entrega de aplicações a custos reduzidos, confiabilidade e escalabilidade. O ERP Open Source trabalhando no modelo SaaS irá permitir às empresas para extrair todos os benefícios associados com as tecnologias utilizadas. Esta tese apresenta um modelo e uma framework para ERP Open Source SaaS. O modelo e a framework foram baseados na revisão de literatura e ambos foram avaliados pelo trabalho empírico. Para validar o modelo e a framework foi implementado num ERP de código aberto que já existe no mercado tendo sido adaptado à realidade Português. Como uma segunda validação do artefato, o ERP foi utilizado para fins de aprendizagem por estudantes universitários. Aqui também são relatados os resultados de sua experiência de uso. Esta pesquisa mostra que existem alternativas localizadas do ERP Software de Código Aberto para que possam ser usados num contexto de Cloud pelas empresas

    ERP projects : an examination of the factors influencing additional unplanned effort in the project life-cycle

    Get PDF
    Includes bibliographical references (leaves 125-143).For over a decade, ERP systems have been the target of significant amounts of investment in organisations. Some have reaped the benefits anticipated while others struggle to achieve the required level of success. In fact, based on available statistics, numerous organisations have faced problems in keeping their allocated budget and time schedules on track often facing the threat of failure, escalation or significant redirection in their projects. As a result, organisations are seen to spend what can be termed as additional unplanned effort (AUE) in order to try and achieve a certain level of success given budget and time constraints. Using the concept called AUE, derived from topics such as ERP project success and failure, the ERP life-cycle framework and critical success factors (CSFs) relevant to the life-cycle phases, this study attempted to investigate the factors that influence AUE in the phases ofthe ERP life-cycle which in this study consist of the pre-implementation and implementation phases specifically. A sub-objective was also to investigate the possible influence that the presence of factors, responsible for escalation of commitment (EoC) in IT projects, have on AUE in ERP projects. Based on a qualitative mUltiple case-study of 5 ERP projects at different organisations, results showed that there are several factors that influence AUE in satisfying CSFs in each phase of the life-cycle. Particularly, in the pre-implementation phase, factors such as the justification for ERP adoption, the formalisation of an ERP vision, the finalisation of an ERP package choice, the stability of organisational structure, the organisation and flow of the acquisition process, the nature of market conditions and the type of internal and external partnership were found important in influencing AUE in that phase. In the implementation phase factors such as the formalisation of an implementation strategy, the management of organisational momentum and resistance to change, the maintenance of external partnership relationships, conditions external to the organisation, the nature of the organisation and the management of project factors were found important
