Abstract

Virtualization is the simulation or emulation of computer resources to the user (Grauer, n.d.; Simpson, 2008). This chapter discusses virtualization as a viable classroom methodology for providing students with course relevant hands-on experience (Simpson, 2008) while synchronizing course specific content in traditional on-ground and online courses (Pheils, 2010). More specifically, this chapter provides an overview of virtualization, detailing several open source tools, and offering possible applications for incorporation into other courses including free resources for sample content. Proof-of-concept is established through examples of successful usage at two colleges. The adoption of virtualization within course development may provide a solution that spans disciplines and offers students the ability to practice and further their studies beyond the classroom.

Abstract

Purpose

The purpose of this study is to investigate whether online apparel shoppers' adoption of product virtualization technologies is facilitated more by hedonic motivations than functional motivations due to the hedonic nature of the product virtualization technologies.

Design/methodology/approach

In addition to the focus group interview, two separate online surveys with links to a stimulus web site containing one of the two product virtualization technologies was conducted to a national online shopper sample. The data were analyzed using structural equation modeling by comparing the structural coefficients of hedonic and functional motivations on the attitude toward using the product virtualization technologies. The linear combination of functional and hedonic roles of each technology was examined using discriminant function analysis to see if the results were consistent.

Findings

The results showed that the hedonic motivation had a stronger positive relationship than functional motivations with the attitude toward using product virtualization technologies. The empirical findings of this study confirm our proposition that perceived entertainment value is a stronger determinant of attitude toward using product virtualization technologies than perceived usefulness.

Originality/value

The findings of the paper support the idea that the direction of technology acceptance model related research should be drawn by the (functional or hedonic) purpose of the technology/system. Based on the current findings, it seems likely that the predictive importance of the hedonic or functional benefits on attitude toward using a particular technology/system will depend, to a large extent, on the primary purpose of the system/technology.

Abstract

Purpose

The purpose of this paper is to understand how higher education institutions (HEIs) in developing countries can migrate their physical administrative work environment to a virtual platform to improve information management.

Design/methodology/approach

The paper employs an interpretive case study approach and a combined lens of activity and agency theories to understand how a developing country HEI attempted to improve its information management by migrating from a physical to a virtual administrative work environment.

Findings

The findings show how contradictions caused by role conflicts, administrative staff’s fear of elimination and external consultants’ limited understanding of administrative rules and procedures can hamper work environment virtualisation. Such challenges should be resolved in order to achieve a successful virtual work environment that supports timely and accurate information management.

Research limitations/implications

The study is limited by its single case perspective in one developing country. However, future studies can compare the experiences of HEIs from developed and developing countries in order to account for contextual differences.

Practical implications

The study provides practitioners with insight into how to address conflicts between employees (as potential users) and external consultants during virtual system development and implementation. In particular, role conflict, fear of eliminating some administrative staff and consultants’ limited understanding of administrative work procedures should be resolved for successful work environment virtualisation.

Originality/value

The study is the first attempt to offer rich insight into the challenges associated with administrative work environment virtualisation for improved information management in HEIs, through the principal-agent relationship.

Abstract

Purpose

Supply chains (SCs) have been growingly virtualized in response to the market challenges and opportunities that are presented by new and cost-effective internet-based technologies today. This paper designed a virtual closed-loop supply chain (VCLSC) network based on multiperiod, multiproduct and by using the Internet of Things (IoT). The purpose of the paper is the optimization of the VCLSC network.

Design/methodology/approach

The proposed model considers the maximization of profit. For this purpose, costs related to virtualization such as security, energy consumption, recall and IoT facilities along with the usual costs of the SC are considered in the model. Due to real-world demand fluctuations, in this model, demand is considered fuzzy. Finally, the problem is solved using the Grey Wolf algorithm and Firefly algorithm. A numerical example and sensitivity analysis on the main parameters of the model are used to describe the importance and applicability of the developed model.

Findings

The findings showed that the Firefly algorithm performed better and identified more profit for the SC in each period. Also, the results of the sensitivity analysis using the IoT in a VCLSC showed that the profit of the virtual supply chain (VSC) is higher compared to not using IoT due to tracking defective parts and identifying reversible products. In proposed model, chain members can help improve chain operations by tracking raw materials and products, delivering products faster and with higher quality to customers, bringing a new level of SC efficiency to industries. As a result, VSCs can be controlled, programmed and optimized remotely over the Internet based on virtual objects rather than direct observation.

Originality/value

There are limited researches on designing and optimizing the VCLSC network. This study is one of the first studies that optimize the VSC networks considering minimization of virtual costs and maximization of profits. In most researches, the theory of VSC and its advantages have been described, while in this research, mathematical optimization and modeling of the VSC have been done, and it has been tried to apply SC virtualization using the IoT. Considering virtual costs in VSC optimization is another originality of this research. Also, considering the uncertainty in the SC brings the issue closer to the real world. In this study, virtualization costs including security, recall and energy consumption in SC optimization are considered.

Highlights

  1. Investigates the role of IoT for virtual supply chain profit optimization and mathematical optimization of virtual closed-loop supply chain (VCLSC) based on multiperiod, multiproduct with emphasis on using the IoT under uncertainty.

  2. Considering the most important costs of virtualization of supply chain include: cost of IoT information security, cost of IoT energy consumption, cost of recall the production department, cost of IoT facilities.

  3. Selection of the optimal suppliers in each period and determination of the price of each returned product in virtual supply chain.

  4. Solving and validating the proposed model with two meta-heuristic algorithms (the Grey Wolf algorithm and Firefly algorithm).

Abstract

The recent rapid commercialization and adoption of Internet technologies has driven a process of supply chain virtualization, transforming conventional work practices across organizations. In an effort to provide a better understanding of this emerging phenomenon, this paper presents three key elements of supply chain virtualization, including: the formation of virtual trading communities; the emergence of virtual knowledge communities; and the relocation and integration of inter‐organizational business processes in the cyberspace. The transformations and consequences of virtualization are illustrated in the context of the Hong Kong textile and clothing industry. The experience of Hong Kong suggests that supply chain virtualization has propelled a structural change in buyers‐intermediaries‐sellers relationships, called for a novel approach to knowledge management, and accelerated internationalization of small‐ and medium‐sized enterprises. Managers and policy makers are advised to adopt new mindsets and practices in the face of these challenges.

This study investigated the impact of the virtualization requirements of the learning process on students' satisfaction and their intention to continue using online learning.

Abstract

Purpose

This study investigated the impact of the virtualization requirements of the learning process on students' satisfaction and their intention to continue using online learning.

Design/methodology/approach

A research model was developed using the process virtualization theory (PVT); it was validated empirically using data obtained from an online questionnaire-based survey of 489 undergraduate students.

Findings

The main results support the role of representation for sensory requirements, sensory requirements, reach, representation for relationship requirements and relationship requirements on shaping students' satisfaction, which all also have a significant influence on students' intention to continue using online learning. Relevance factors are responsible for 61.6% of the variance in students' satisfaction and 83.6% of the variance in their intention to continue using online learning. However, neither the synchronism requirements nor the identification and control requirements had a significant effect on students' satisfaction or on their intention to continue using online learning.

Originality/value

The present research focused on PVT in an online learning context; consequently, a new set of factors that influenced students' satisfaction with and intentions to continue using online learning was empirically tested for the first time. This research contributes to the literature on information systems because it advances the generalizability and applicability of the PVT in a new context and new cultural setting. Moreover, the research apprises researchers and practitioners of new factors, which should be understood and fulfilled to make virtual learning equivalent to the face-to-face learning experience.

Abstract

Purpose

In the last decade, cloud manufacturing (CMfg) has attracted considerable attention from academia and industry worldwide. It is widely accepted that the design and analysis of cloud manufacturing architecture (CMfg-A) are the basis for developing and applying CMfg systems. However, in existing studies, analysis of the status, development process and internal characteristics of CMfg-A is lacking, hindering an understanding of the research hotspots and development trends of CMfg-A. Meanwhile, effective guidance is lacking on the construction of superior CMfg-As. The purpose of this paper is to review the relevant research on CMfg-A via identification of the main layers, elements, relationships, structure and functions of CMfg-A to provide valuable information to scholars and practitioners for further research on key CMfg-A technologies and the construction of CMfg systems with superior performance.

Design/methodology/approach

This study systematically reviews the relevant research on CMfg-A across transformation process to internal characteristics by integrating quantitative and qualitative methods. First, the split and reorganization method is used to recognize the main layers of CMfg-A. Then, the transformation process of six main layers is analysed through retrospective analysis, and the similarities and differences in CMfg-A are obtained. Subsequently, based on systematic theory, the elements, relationships, structure and functions of CMfg-A are inductively studied. A 3D printing architecture design case is conducted to discuss the weakness of the previous architecture and demonstrate how to improve it. Finally, the primary current trends and future opportunities are presented.

Findings

By analyzing the transformation process of CMfg-A, this study finds that CMfg-A resources are developing from tangible resources into intangible resources and intelligent resources. CMfg-A technology is developing from traditional cloud computing-based technology towards advanced manufacturing technology, and CMfg-A application scope is gradually expanding from traditional manufacturing industry to emerging manufacturing industry. In addition, by analyzing the elements, relationships, structure and functions of CMfg-A, this study finds that CMfg-A is undergoing a new generation of transformation, with trends of integrated development, intelligent development, innovative development and green development. Case study shows that the analysis of the development trend and internal characteristics of the architecture facilitates the design of a more effective architecture.

Research limitations/implications

This paper predominantly focuses on journal articles and some key conference papers published in English and Chinese. The reason for considering Chinese articles is that CMfg was proposed by the Chinese and a lot of Chinese CMfg-A articles have been published in recent years. CMfg is suitable for the development of China’s manufacturing industry because of China’s intelligent manufacturing environment. It is believed that this research has reached a reliable comprehensiveness that can help scholars and practitioners establish new research directions and evaluate their work in CMfg-A.

Originality/value

Prior studies ignore the identification and analysis of development process and internal characteristics for the current development of CMfg-A, including the main layers identification of different CMfg-As and the transformation process analysis of these main layers, and in-depth analysis of the inner essence of CMfg-A (such as its elements, relationships, structure and functions). This study addresses these limitations and provides a comprehensive literature review.

Abstract

Purpose

The physical server transition to virtualized infrastructure server have encountered crucial problems such as server consolidation, virtual machine (VM) performance, workload density, total cost of ownership (TCO), and return on investments (ROIs). In order to solve the problems mentioned above, the purpose of this paper is to perform the analysis of virtualized cloud server together with shared storage as well as the estimation of consolidation ratio and TCO/ROI in server virtualization.

Design/methodology/approach

This paper introduces five distinct virtualized cloud computing servers (VCCSs), and provides the appropriate assessment to five well-known hypervisors built in VCCSs. The methodology the authors proposed in this paper will gives people an insight into the problem of physical server transition to virtualized infrastructure server.

Findings

As a matter of fact, VM performance seems almost to achieve the same level, but the estimation of VM density and TCO/ROI are totally different among hypervisors. As a result, the authors have the recommendation to choose the hypervisor ESX server if you need a scheme with higher ROI and lower TCO. Alternatively, Proxmox VE would be the second choice if you like to save the initial investment at first and own a pretty well management interface at console.

Research limitations/implications

In the performance analysis, instead of ESX 5.0, the authors adopted ESXi 5.0 that is free software, its function is limited, and does not have the full functionality of ESX server, such as: distributed resource scheduling, high availability, consolidated backup, fault tolerance, and disaster recovery. Moreover, this paper do not discuss the security problem on VCCS which is related to access control and cryptograph in VMs to be explored in the further work.

Practical implications

In the process of virtualizing the network, ESX/ESXi has restrictions on the brand of the physical network card, only certain network cards can be detected by the VM. For instance: Intel and Broadcom network cards. The newer versions of ESXi 5.0.0 and above now support parts of Realtek series (Realtek 8186, Realtek 8169, and Realtek 8111E).

Originality/value

How to precisely assess the hypervisor for server/desktop virtualization is also of hard question needed to deal with it crisply before deploying new IT with VCCS on site. The authors have utilized the VMware calculator and developed an approach to server/desktop consolidation, virtualization performance, VM density, TCO, and ROIs. As a result, in this paper the authors conducted a comprehensive approach to analyze five well-known hypervisors and will give the recommendation for IT manager to choose a right solution for server virtualization.

Abstract

Purpose

The purpose of this paper is to describe a virtualisation model of RFID enabled infrastructure incorporating non‐standard radio frequency identification (RFID) components. The model is implemented as a software service that draws upon other sources of internet services.

Design/methodology/approach

In a global supply chain environment, circumstances at different locations may not allow RFID system to be used. Some supply chain members do not have compatible network infrastructure in place. These include RFID frameworks such as China's National Product Codes and Japan's ubiquitous identification which are utilised around the world. There is also a reachability problem for consignments going offsite. The paper introduces a service abstraction layer (SAL) in the RFID architecture to remove dependency on specific RFID framework. From this principle, the paper introduces a new virtual infrastructure that interfaces with emerging identification technologies.

Findings

The model bridges the gaps that exist between various RFID standards, as well as utilising various technologies to emulate data capture devices so that the information chain remains intact across the global network. The resulting system significantly reduces the costs of commissioning and operating costs of existing RFID infrastructures.

Research limitations/implications

The new system has been tested in real industry environment with defined scope and coverage. The implication due to full roll out of the technologies in global supply chains still requires further investigation.

Practical implications

Usability of the virtualised RFID infrastructures depends on the cooperation among partners in the supply chain rather than the technology level. New business rules are required when special stakeholders such as customs are included in this virtualised infrastructure.

Originality/value

The concept of virtualisation has been used in operating systems, but its application to supply chain has not been explored before. Introduction of the SAL allows interoperability of systems handling goods tracking events through the supply chain.
