The aim of this paper is to examine the role of perceived system quality (PSQ) as an antecedent to the implementation success (IMP) of ERP projects, and its interrelationships with other antecedents that influence the outcome of organizational adoption process.

The authors derive a model containing the relationships between PSQ and IMP and between PSQ and some antecedents of organizational adoption. The relationships were analysed with data from a survey of 217 Australian companies, using structural equation modelling.

PSQ is an important antecedent to implementation success of ERP projects. It also has a positive influence on other antecedents of organizational adoption, namely: perceived information quality, organizational readiness and perceived strategic value of adoption.

Prior findings have shown that PSQ is a significant antecedent to the adoption of ERP by individuals and organizations and the paper extends this by providing evidence that PSQ is also a significant antecedent to implementation success. The authors have empirically established the role of interrelationships among antecedent factors at the adoption stage of ERP systems.

Establishing a proposed ERP system's system quality, when considering whether to adopt a particular system is important, as it influences the other important antecedents and beliefs on the potential benefits from an ERP project. Understanding of system quality attributes can help managers put in place strategies to avoid potential pitfalls at the project implementation stage.

Empirical evidence of the importance of PSQ for success in ERP adoption, implementation and explanation of how and why this has positive effects on other antecedents.

This study aims to investigate the effects of different search and browse features in digital libraries (DLs) on task interactions, and what features would lead to poor user experience.

Three operational DLs: ACM, IEEE CS, and IEEE Xplore are used in this study. These three DLs present different features in their search and browsing designs. Two information‐seeking tasks are constructed: one search task and one browsing task. An experiment was conducted in a usability laboratory. Data from 35 participants are collected on a set of measures for user interactions.

The results demonstrate significant differences in many aspects of the user interactions between the three DLs. For both search and browse designs, the features that lead to poor user interactions are identified.

User interactions are affected by specific design features in DLs. Some of the design features may lead to poor user performance and should be improved. The study was limited mainly in the variety and the number of tasks used.

The study provided empirical evidence to the effects of interaction design features in DLs on user interactions and performance. The results contribute to our knowledge about DL designs in general and about the three operational DLs in particular.

Through this research study, the authors found that digital thread has made significant progress in the life cycle management of the US Air Force. The authors hope that by reviewing similar studies in the aerospace field, the meaning of digital thread can be summarized and applied to a wider range of fields. In addition, theoretically, the definition of digital twin and digital thread are not unified. The authors hope that the comparison of digital thread and digital twin will better enable scholars to distinguish between the two concepts. Besides, the authors are also looking forward that more people will realize the significance of digital thread and carry out future research.

Complete research about digital thread and the relevant concept of the digital twin is conducted. First, by searching in Google Scholar with the keyword “digital thread”, the authors filter results and save literature with high relevance to digital thread. The authors also track these papers’ references for more paper of digital thread and digital twin. After removing the duplicate and low-relevance literature, 72 digital thread-related literature studies are saved and further analyzed from the perspective of time development, application field and research directions.

Digital thread application in industries other than the aviation manufacturing industry is still relatively few, and the research on the application of digital thread in real industrial scenarios is mainly at the stage of framework design and design-side decision optimization. In addition, the digital thread needs a new management mechanism and organizational structure to realize landing. The new management mechanism and the process can adapt to the whole life cycle management process based on the digital thread, manage the data security and data update, and promote the digital thread to play a better effect on the organizational management.

Based on a review of digital thread, future research directions and usage suggestions are given. The fault diagnosis of high-speed train bogie as an example shows the effectiveness of the method and also partially demonstrates the advantages and effects brought by the digital thread connecting the data models at various stages.

This paper first investigates and analyzes the theoretical connotation and research progress of digital thread and gives a complete definition of digital thread from the perspective of the combination of digital thread and digital twins. Next, the research process of digital thread is reviewed, and the application fields, research directions and achievements in recent years are summarized. Finally, taking the fault diagnosis of high-speed train bogie as an example partially demonstrates the advantages and effects brought by the digital thread connecting the data models at various stages.

The purpose of this paper is to propose an innovative method to extend the operating range of the laser tracking system and improve the accuracy and automation of boresighting by designing a measurement instrument. Boresighting is a process that aligns the direction of special equipment with the aircraft reference axis. Sometimes the accurate measurement and adjustment of the equipment and the aircraft are hard to achieve.

The aircraft is moved by an automatic adjustment system which consists of three numerical control positioners. For obtaining the position of the bore axis, an instrument with two measurement points is designed. Based on the multivariate normal distribution hypothesis, an uncertainty evaluation method for the aiming points is introduced. The accuracy of the measurement point is described by an uncertainty ellipsoid. A compensation and calibration method is proposed to decrease the effect of manufacturing error and deflection error by the finite element analysis.

The experimental results of the boresighting measurement prove that the proposed method is effective and reliable in digital assembly. The measurement accuracy of the angle between the bore axis and the reference axis is about ±0.004°. In addition, the measurement result is mainly influenced by the position error of the instrument.

The results of this study will provide a new way to obtain and control the installation deviation of part in aircraft digital assembly and will help to improve the precision and efficiency. This measurement method can be applied to obtain the axis of a deep blind hole.

The XTRA access system is aimed at making the interaction with expert systems much easier for inexperienced users. It communicates with the user in a natural language (German) extracting data relevant to the expert system from the natural language input. It answers users' queries concerning the terminology used and provides what the developers describe as “User‐accommodated natural‐language verbalisations of results and explanations provided by the expert system”. This development is described by J. Allgayer, K. Harbusch, A. Kobsa, C. Reddig, N. Reithinger and D. Schmauks in the International Journal of Man‐Machine Studies, Vol. 31, Part 2, August 1989, pp. 161–95. The developers of this system have introduced a number of novel artificial intelligence techniques. These have included the combination of natural language user input and user gestures on the terminal screen. Four different knowledge sources aid referent identification and simultaneous communication of the access system with the user and the expert system have been incorporated.

The key purpose of the current study is investigating the direct impact of information technology (IT) assimilations, flexible IT infrastructure, and supply chain competencies (supply side, demand side) on the supply chain performance of manufacturing firms. Meanwhile, the study has also estimated the mediating role of supply chain agility (SCA). Among 360 selected respondents for the underlying research, only 267 respondents have responded well and returned them back, thereby indicating 74% response rate for the survey. For the inferential analysis, the Partial Least Square Structural Equation Modeling was performed in Smart PLS 3.0. In context to this study, process compliance is the adherence and the execution of supply chain processes, including the processes related to distribution and production of management processes. On the basis of this theoretical background, the demand and supply-side competence are considered as the firms’ internal aspects. As a dynamic capability, the SCA enables firms to influence and respond to the firm’s external environment. Thus, the presence of such competencies allows to react against market developments. The resource-based view theory supports this argument, and states that competencies is an effective resource for developing dynamic capabilities.

This paper aims to study integrated metadata access infrastructure for a network of federated curated data repositories. With the increase in collaborative initiatives among diverse scientific discipline, infrastructure should be in place to facilitate effective information sharing. Scientific data sharing involves provisioning, curation and dissemination of information about the various datasets for discovery and access by other peers, which is achieved using metadata services. The heterogeneous nature of various distributed dataset repositories has resulted in the use of heterogeneous metadata services. This poses some challenges in efficient dataset sharing and information retrieval. To allow for universal accessibility of these autonomous curated data repositories, it is important to establish cross-integration on these data repositories for information sharing.

The authors address this problem through provisioning of a universal metadata interface design that can be integrated with some popular metadata services such as integrated rule-oriented data system (iRODS), OpenDap/THREDDS and MERCURY. Given a network of federated heterogeneous distributed metadata services over autonomous curated data repositories, the authors present an implementation of a universal interface system that can probe and query different metadata databases to access the essential information provided for data discovery and enable data migration.

The authors present the architecture that integrates and allows communication between our interface and the various autonomous data repositories. The authors show how they can integrate their system with THREDDS and iRODS to accomplish data discovery and access operations without altering the implementations of the metadata services at their remote locations.

Their system provides unique architecture for information discovery and metadata searches which employs the application programming interfaces for the respective metadata services and communicates using the Zero C Internet communication engine (ICE) protocol.

This paper sets out to empirically analyse the integration process that firms follow to implement supply chain management (SCM). This study has been inspired by the integration model proposed by Stevens.

Uses the survey method.

The results show that there are companies in three different integration stages. In stage I, companies are not integrated. In stage II, companies have a medium‐high level of internal integration in the logistics‐production interface, a low level of internal integration in the logistics‐marketing interface, and a medium level of external integration. And, in stage III, companies have high levels of integration in both internal interfaces and in some of their supply chain relationships.

First, only one side of the manufacturer‐retailer relationship was considered, and, second, there was a reduced number of cases in each cluster.

As firms' survival lies on integration, a good understanding of the integration process is a key aspect. In this subject, this study has a main implication for managers: in the integration process, firms must achieve a relatively high level of collaboration among internal functions before initiating any external integration.

The contribution of this study is to describe the integration process, comparing two levels of internal integration (logistics‐marketing and logistics‐production) and analysing the relationship between these internal integration levels and the level of external integration. Many studies consider internal or external integration from the logistics point of view, but very few consider both levels of integration simultaneously. This study differs from the existing literature in the fact that it explores the sequence of integration stages in an integration process.

Unicorn and STILAS are multiuser client/server systems developed in and for the Unix environment to automate all aspects of information management, from cataloging and authority control to intelligent access of non‐SIRSI databases. In keeping with the client/server concept, SIRSI has introduced a graphical user interface (GUI) to Unicorn and STILAS. The SIRSI system provides a path to information both inside and outside the library. SIRSI provides a standard interface, an “Intelligent Interface” client to diverse database systems and other vendors' library automation systems. SIRSI's Reference Database Managers provide an intelligent connection to locally mounted reference databases. SIRSI's VIZION, a stand‐alone desktop client, provides an automatic graphical user interface to hundreds of online sources of information and services available through the Internet and via modem. Furthermore, SIRSI has recently introduced WebCat, which facilitates mounting and access to the complete catalogs and other services of libraries over the Internet's World Wide Web.

The primary purpose of this paper is to present an integrated framework for user interface prototyping and evaluation for the development of information systems and to present architecture for evaluating generic applications.

The framework is constructed through combining two distinctive methods of prototyping and evaluation, statechart and goals, operators, methods, and selection rules. Relevant methods and architectures of the integrated framework are presented in unified modeling language when possible.

The importance of the usability of information systems is highlighted in this research. However, it still lacks an integrated framework for information system development and usability evaluation. This paper provides a framework that evaluation method is intertwined with user interface prototyping to shorten the time of development lifecycle. The architecture for evaluating generic applications is also invaluable for motion and time study and the procurement of vender‐provided systems.

The user base of information systems is diverse and the requirements of these systems change over time. This paper provides a framework that helps managers and engineers smooth and shorten the development phases. For future works, an object‐oriented programming framework and a tool for evaluating generic applications will be developed.

This paper proposes a comprehensive framework for combining prototyping and evaluation, as well as architecture for the evaluation of generic applications. It shortens the development phases by using formal modeling for user interface construction and evaluation. It also provides means to evaluate candidate systems whose program logics cannot be accessed and modified. It also complements the models used in the framework by extending their practical and academic values.
