The authors studied enterprise systems adoption in transition and less-developed economies within the European Union in search of determinants (critical success factors and barriers) across the system lifecycle. They found 14 determinants drawing from interviews with practitioners whose experience exceeds 280 projects. The authors compared their data with prior results from well-developed countries and concluded that determinants and their criticality across the lifecycle depend on the level of economic development. The authors discussed implications and provided recommendations. 相似文献

Of all the benefits public access to computers (PAC) offer users, the most valued by users are having more information for stronger relationships, better learning, and effective transactions. This article analyzes the most salient benefit, more information for stronger relationships with friends and family. Results of a qualitative study among users of libraries, telecenters, and cybercafés in Colombia, South America, show that social media and personal relationships can also have an important community and sociopolitical dimension. By fostering a sense of belonging and connectedness to community and to a larger world, PAC usage often leads to feelings of empowerment and development of social capital, two intangible factors that are critical for community development. This study used a mixed-methods approach, combining surveys and interviews in five regions of the country, to uncover the benefits of PAC for underserved communities. Its findings contribute new insight about the impact of information and communication technologies on community development and social inclusion. 相似文献

The paper is concerned with investigating relationships between labor productivity and information and communication technology (ICT) components such as the use of enterprise resource planning (ERP), e-commerce and customer relationship management (CRM) software, and the number of ICT specialists at the country level. The proposed approach uses a neoclassical framework of growth accounting and a translog production function to examine the impact of ICT components on labor productivity in the transition and developed economies of the European Union (EU). Our findings show the positive and significant influence of selected ICT components on labor productivity in EU countries. Moreover, the results indicate that the impact of ERP, e-commerce and CRM software on labor productivity is greater in transition economies than in developed economies of the EU. 相似文献

The article is intended to aid students and consumers of Cognitive Systems Engineering (CSE) in learning about CSE. A proliferation of terms describing CSE and related constructs makes it difficult to sort out differences and similarities across approaches. To aid the reader in exploring CSE, we examine areas of confusion surrounding CSE, define CSE, and discuss the role of CSE in the systems engineering design process. We advocate the use of CSE principles and methods as a means to incorporate worker needs, expertise, cognitive demands, constraints, and goals throughout the design process. Articulation of the value case for CSE is offered as a vehicle to foster collaboration across disciplines. © 2009 Wiley Periodicals, Inc. Syst Eng 相似文献

Recently, enterprise systems have been extensively adopted to boost enterprise competitiveness. The development and implementation of enterprise systems is a knowledge intensive procedure, being related to enterprise processes and involving information, system and software engineering technologies. Consequently, knowledge management is required to enhance the effectiveness of enterprise system development and implementation, thus helping to increase industrial competitiveness.This study aims to develop a distributed knowledge model for knowledge management, capable of supporting the collaborative development and implementation of enterprise systems. This objective can be obtained by performing the following tasks: (1) modeling and characterization of the collaborative development and implementation process, (2) identification, analysis and modeling of involved knowledge, and (3) development of a distributed knowledge model for knowledge management related to the collaborative development and implementation of enterprise systems. 相似文献

With the process of globalisation and the development of management models and information technologies, enterprise cooperation and collaboration meets a new business and technical environment. The Internet of things, mobile Internet, cloud computing and big data technologies build a sensing environment for all kinds of businesses. Inter enterprise collaboration is also meeting the new challenges of omni-channel marketing, closed-loop supply chain and enterprise networks integration. A data convergence oriented enterprise networks integration architecture with relative enabling technologies is developed in the paper. In order to collect, transfer and fuse data from different data sources, Data Portal (DP) and Collaboration Agent (CA) concepts are introduced, which present a lightweight and loosely coupled infrastructure for enterprise networks integration. How to use the developed technologies to solve problems of product lifecycle management and omni-channel marketing management are discussed in detailed cases studies. 相似文献

Today, and for the foreseeable future, organizations will face ever-increasing levels of complexity and uncertainty. Many believe that enterprise architecture (EA) will help organizations address such difficult terrain by guiding the design of adaptive and resilient enterprises and their information systems. This paper presents the “Grand Challenges” that we believe will challenge organizations in the future and need to be addressed by enterprise architecture. As a first step in using enterprise architecture as a solution for overcoming identified challenges, the Zachman Enterprise Architecture Framework is used to guide and structure the discussion. The paper presents the “Grand Challenges” and discusses promising theories and models for addressing them. In addition, current advances in the field of enterprise architecture that have begun to address the challenges will be presented. In conclusion, final thoughts on the future of enterprise architecture as a research field and a profession are offered. 相似文献

Data centers today host a number of computational resources to support the increasing demand for computation and storage. Understanding how these physical and virtual machines transition between different states of operation (referred to as machine lifecycle) enables more efficient data center operation management. Furthermore, it helps data center operators define policies on how new computational resources can be added or existing infrastructure decommissioned. Using Google cluster trace data set version 3 collected from approximately 96 k machines, we analyze machine failure and changes in machine lifecycle over time. We observed that there is a 13% chance of another machine failure under the same network switch within 1 min of the previous machine failure. A Markov chain-based model is proposed, that can predict machine states at any given time. Using the model and estimated probabilities, we predicted the machine state over a span of several days with a high probability. Using the predicted machine state, we reconstructed the active machines trend and compared this with the trend reported in the data set, observing an error of 1.76%. 相似文献

This study presents an evolutionary approach to support dynamic enterprise modeling for enterprise process cooperative scheduling
and management. In this paper, an evolutionary dynamic enterprise process modeling method was proposed from the concepts of
enterprise process evolution to zero-time enterprise modeling and layered complex enterprise modeling. Based on an autonomous
agent development platform, an agent-based enterprise collaborative modeling environment has been implemented by integrating
several software resource agents that wrap main function modules of EPMS. Scheduling strategies, algorithms, and process-driven
cooperative scheduling mechanism are also discussed.

The hierarchy of Symbolic Transition Systems, introduced by Henzinger, Majumdar and Raskin, is an elegant classification tool for some families of infinite-state operational models that support some variants of a symbolic “backward closure” verification algorithm. It was first used and illustrated with families of hybrid systems.In this paper we investigate whether the STS hierarchy can account for classical families of infinite-state systems outside of timed or hybrid systems. 相似文献

Intelligent products are an undeniable asset for efficient product lifecycle management (PLM), providing ways to capture events related to physical objects at various locations and times. Today and more than ever before, PLM tools and systems must be built upon standards for enhancing interoperability among all product stakeholders and developing tools independent of specific vendors, applications, and operating systems. Based on this observation, this paper develops strategies to improve “information sustainability” in PLM environments using standardized communication interfaces defined by a recent standard proposal named quantum lifecycle management (QLM) messaging standards. More concretely, data synchronization models based upon QLM standards are developed to enable the synchronization of product-related information among various systems, networks, and organizations involved throughout the product lifecycle. Our proposals are implemented and assessed based on two distinct platforms defined in the healthcare and home automation sectors. 相似文献

The rapid changes in today's socio-economic and technological environment in which the enterprises operate necessitate the identification of new requirements that address both theoretical and practical aspects of the Enterprise Information Systems (EIS). Such an evolving environment contributes to both the process and the system complexity which cannot be handled by the traditional architectures. The constant pressure of requirements for more data, more collaboration and more flexibility motivates us to discuss about the concept of Next Generation EIS (NG EIS) which is federated, omnipresent, model-driven, open, reconfigurable and aware. All these properties imply that the future enterprise system is inherently interoperable. This position paper presents the discussion that spans several research challenges of future interoperable enterprise systems, specialized from the existing general research priorities and directions of IFAC Technical Committee 5.3,1 namely: context-aware systems, semantic interoperability, cyber-physical systems, cloud-based systems and interoperability assessment. 相似文献

The human population reached 7 billion at the end of October 2011, accentuating the challenge to increase food production to meet the demand. Offshore mariculture, which does not depend on wild fish harvest, has the potential to become a primary food source to meet this demand. Despite an overall interest and justification in investments in offshore aquaculture, there are very few offshore cage designs suitable for use today. The goal of the current paper is to describe a research project that applied systems engineering principles to develop and document a set of requirements and identify the relevant technical components that are needed to design a sustainable offshore cage system. Requirements from the sector should be met by a robust environmentally friendly cage system ensuring the welfare of the fish and capable of producing a quality fish product demanded by the consumer. Future design work will build on the proposed preliminary architecture to satisfy these requirements. © 2012 Wiley Periodicals, Inc. Syst Eng 相似文献
