Abstract

Purpose

This paper aims to solve the nonlinear problem in the uncertainty evaluation of the measurement of the positioning repeatability (RP) of industrial robots and provide guidance to restrict the uncertainty of measurement of RP (uRP).

Design/methodology/approach

Firstly, some uncertain sources existing in the measurement procedure of RP are identified. Secondly, the probability distribution function (PDF) of every source is established on the basis of its measurements. Some spatial combined normal distributions are adopted. Then, a method, based on Monte Carlo method (MCM) and established measurement model, is developed for the estimation of uRP. Thirdly, some tests are developed for the identification and validation of the selected PDFs of uncertain sources. Afterwards, the proposed method is applied for the evaluation and validation of the uRP. Finally, influence analyses of some key factors are proposed for the quantification of their relative contributions to uRP.

Findings

Results show that the proposed method can reasonably and objectively estimate the uRP of the selected industrial robot, and changes of the industrial robots’ position and the laser trackers measurement are correlated. Additionally, the uRP of the selected industrial robot can be restricted by using the results of its key factors on uRP.

Originality/value

This paper proposes the spatial combined normal distribution to model the uncertainty of the repeatability of the laser tracker and industrial robot. Meanwhile, the proposed method and influence analyses can be used in estimating and restricting the uRP and thus useful in determining whether the RP of a tested industrial robot meets its requirements.

Abstract

Purpose

In the past four decades, substantial air traffic growth has triggered enthusiasm in the aviation sector. At the same time, this growth has posed challenges to its financial and environmental sustainability commitments. A buzz has been centered on introducing and supporting aviation sustainability initiatives. These challenges have led to acknowledging the need to reduce aviation fuel consumption, a function of multiple factors. The different stakeholders having a diverse type of interplay govern the effective implementation of the factors at different decision levels (strategic, tactical and operational). Thus, the present study aims to critically examine various decision levels involved to understand opportunities and requirements related to aviation sustainability.

Design/methodology/approach

In this study, the best–worst method is used to quantify different decision levels’ role on various factors affecting aviation fuel consumption.

Findings

The results of this study signify that tactical-level decisions are most influential in reducing aviation fuel consumption with the highest impact (0.41) followed by operational-level decisions (0.30) and strategic-level decisions (0.29), respectively.

Research limitations/implications

The results point toward the critical role of middle-level hierarchy, i.e. aircraft manufacturers, airlines and others in the aviation industry’s sustainable growth. Thus, middle-level stakeholders must be inspired and empowered to act, being at the center they link the other two levels.

Originality/value

This study has added to the body of knowledge by exploring the decision-making competencies needed by different aviation sector stakeholders. It also presents the possible options available in the sector and the role of stakeholders at different levels in exploiting and implementing the sustainable aviation sector changes.

Abstract

Purpose

An increasing number of immersive technologies have been adopted in museum tourism in response to shifting consumer habits in the digital era. In contrast, the authenticity experience of museum tourists relies on genuine relics, the environment and activities, which are ancient or traditional. This raises the question of whether tourists can perceive authenticity in immersive technology-based museum tourism. To address this question, this study aims to explore the impact of virtual reality (VR) attributes on tourists’ presence, tourism authenticity and subsequent behavioral intentions in virtual museums.

Design/methodology/approach

Data were collected via scenario-based surveys of participants who had taken virtual museum tours based on VR. A total of 174 effective questionnaires were collected for exploratory factor analysis via SPSS 25. Afterward, 597 questionnaires were obtained for confirmatory factor analysis and path analysis via Mplus 7.4.

Findings

A conceptual model of how VR attributes influence presence, authenticity and visit intention was developed. There is a chain intermediary between presence and visit intentions, from original authenticity to interactive authenticity and then to emotional authenticity. Technology readiness and museum familiarity moderate some relationships between VR attributes and presence.

Practical implications

The findings can guide museums in improving the use of VR. For example, managers can improve the quality of virtual systems and adopt various interactive forms to enhance tourists’ participation experiences.

Originality/value

These research findings contribute to the research area of immersive technology adoption, enhance the understanding of tourism authenticity in the new context of technology application and extend the presence-emotion-intention theory.

Abstract

Purpose

This study aims to explore the relationship between proactive socialization behaviors (PSBs) and work engagement, with a specific focus on the mediating role of social capital resources (SCRs). Additionally, it investigates how proactive personality and perceived organizational support (POS) moderate the organizational assimilation of newcomers in Punjab, Pakistan, through the lens of self-determination theory.

Design/methodology/approach

A cross-sectional survey design was employed, with data collected from diverse organizations across cities in Punjab, Pakistan, including Bhimber, Gujrat, Gujranwala, Lahore, Jhelum, Kharian, Kotla, Mandi Bahauddin, and Sialkot. A total of 1,000 questionnaires were distributed, resulting in 619 valid responses. The sample primarily consisted of individuals with varying levels of work experience, contributing to the diversity of the data. SEM was utilized to analyze the relationships between the studied variables.

Findings

Results indicated a significant positive association between PSBs and work engagement among newcomers. SCRs were found to mediate this relationship, suggesting that proactive behaviors help newcomers accumulate social capital, which enhances work engagement. Moreover, the study reveals that proactive personality and POS significantly moderate the relationship between PSBs and work engagement, with stronger positive associations observed among proactive individuals and those perceiving higher organizational support.

Practical implications

The study underscores the importance of encouraging proactive socialization behaviors and strengthening organizational support systems to foster newcomer engagement and facilitate successful assimilation.

Social implications

Understanding these dynamics can lead to the creation of more inclusive and supportive organizational environments, enhancing both individual well-being and organizational effectiveness.

Originality/value

This research offers new insights into the mechanisms through which PSBs impact work engagement, particularly through the accumulation of SCRs, and highlights the importance of proactive personality and organizational support as moderators.

Abstract

Purpose

The purpose of this study is to reveal the research trends in guest experiences of service robots in the hospitality industry.

Design/methodology/approach

In this study, a review was carried out on the Web of Science (WoS) database with the assistance of bibliometric analysis techniques. Cluster analysis was also employed for this to group important data to determine the relationships and to visualize the areas in which the studies are concentrated. The thematic content analysis method was used to reveal on which customer experiences and on which methods the focuses were.

Findings

On the subject of experiences of service robots, the greatest number of publications was in 2021. In terms of country, China has come to the fore in the distribution of publications. As a result of thematic content analysis, it was determined that the leading factor was the main dimension of emotional experience. In terms of sub-dimensions, social interactions attracted more attention. Most of the studies discussed were not based on any theory. Apart from these, the Technology Acceptance Model (TAM), the Service Quality Model (SERVQUAL) and Perceived Value Theory (PVT) were featured more prominently among other studies.

Research limitations/implications

In this study, only the WoS database was reviewed. In future studies, it would be possible to make contextual comparisons by scanning other databases. In addition to quantitative research designs, social dimensions may be examined in depth following qualitative research methods. Thus, various comparisons can be made on the subject with mixed-method research designs. Experimental research designs can also be applied to where customers have experienced human-robot interactions (HRIs).

Originality/value

In the hospitality industry, it is critical to uncover every dimension of guests' robot acceptance. This study, which presents the current situation on this basis, guides future projections for the development of guest experiences regarding service robots in the hospitality industry.
