Authors: Xidias Elias , Zacharia Paraskevi 
Published: June 2024

PurposeA fleet of mobile robots has been effectively used in various application domains such as industrial plant inspection. This paper proposes a solution to the combined problem of task allocation and motion planning problem for a fleet of mobile robots which are requested to operate in an intelligent industry. More specifically, the robots are requested to serve a set of inspection points within given service time windows. In comparison with the conventional time windows, our problem considers fuzzy time windows to express the decision maker’s satisfaction for visiting an inspection point.Design/methodology/approachThe paper develops a unified approach to the combined problem of task allocation and motion planning for a fleet of mobile robots with three objectives: (a) minimizing the total travel cost considering all robots and tasks, (b) balancing fairly the workloads among robots and (c) maximizing the satisfaction grade of the decision maker for receiving the services. The optimization problem is solved by using a novel combination of a Genetic Algorithm with pareto solutions and fuzzy set theory.FindingsThe computational results illustrate the efficiency and effectiveness of the proposed approach. The experimental analysis leverages the potential for using fuzzy time windows to reflect real situations and respond to demanding situations.Originality/valueThis paper provides trade-off solutions to a realistic combinatorial multi-objective optimization problem considering concurrently the motion and path planning problem for a fleet of mobile robots with fuzzy time windows.

Published: June 2024

PurposeReliability study plays a significant role in supporting the operation of any machinery working in a dynamic and harsh environment. This quality is inherently uncertain and a stochastic variable of any system. This study will be beneficial for designing an appropriate maintenance schedule, reducing unplanned production downtime and reducing maintenance cost of electrical motor operated particularly in dynamic and harsh environmental industries.Design/methodology/approachThis study focused on the effects of operating conditions (OCs) on the operational reliability and remaining useful life (RUL) of machinery. A probabilistic graphical method called Bayesian network (BN) was used for studying the effect of OCs on the system performance. The developed methodology has been demonstrated by analyzing the operational reliability and predicting the RUL of electrical motors operated in a heavy mining machinery.FindingsThe failure probabilities estimated from the historical data of the motor system are failure likelihood, and OCs are the evidence in the developed BN model. It has been observed that the performance and RUL of the motor are significantly influenced by OCs and maintenance. A threshold value of reliability at which the motor system requires maintenance or replacement has been proposed to guide management in decision making.Originality/valueThe Bayesian approach for studying the covariate of motor reliability and RUL estimation is a novel approach. This study will be beneficial for designing an appropriate maintenance schedule, reducing unplanned production downtime and reducing maintenance cost of electrical motor operated particularly in dynamic and harsh environmental industries.

Revealed strategies in wineries’ grape supply: the case of the Canary Islands
Authors: Godenau Dirk , Martin-Rodriguez Gloria , González Gómez Jose Ignacio , Caceres-Hernandez Jose Juan 
Published: June 2024

Purpose
This paper aims to deal with the grape sourcing strategies of wineries in the Canary Islands.

Design/methodology/approach
Sourcing decisions are analysed from official registers of transactions between wineries and their external suppliers. The main sources of information are harvest reports submitted by wineries containing data about observable dimensions of their purchasing decisions. The general behaviour in the wine-grape zones that make up the grape market in the Canary Islands is described, and different strategies of individual wineries are revealed. Grape purchasing decisions are interpreted in terms of the potential explanatory factors involved in the undeclared objectives of wineries’ sourcing strategies. Two research questions are considered in this study: the spatial dimension, which refers to plot location, and the social dimension, which refers to the relationships between wineries and winegrowers.

Findings
The location of grape producers is a key factor in achieving the desired wine quality for wineries. The sourcing strategy of wineries is also influenced by size, but the impact of size varies depending on the short and long-term objectives of wineries.

Originality/value
Typically the literature on grape sourcing strategies relies on interviews with winemakers. However, this paper analyses wineries’ sourcing decisions based on records and reports that reveal their decisions in the specific context of the Canary Islands.

Published: June 2024

PurposeProduction systems occupy geographically dispersed organizations with limited visibility and transparency. Such limitations create operational inefficiencies across the Supply Chain (SC). Recently, researchers have started exploring applications of Digital Twins Technology (DTT) to improve SC operations. In this context, there is a need to provide comprehensive theoretical knowledge and frameworks to help stakeholders understand the adoption of DTT. This study aims to fulfill the research gap by empirically investigating DTT readiness to enable transparency in SC.Design/methodology/approachA comprehensive literature survey was conducted to develop a theoretical model related to Supply Chain Transparency (SCT) and DTT readiness. Then, a questionnaire was developed based on the proposed theoretical model, and data was collected from Indian manufacturers. The data was analyzed using Confirmatory Factor Analysis (CFA) and Structural Equation Modelling (SEM) to confirm the proposed relationships.FindingsThe findings from the study confirmed a positive relationship between DTT implementation and SCT. This study reported that data readiness, perceived values and benefits of DTT, and organizational readiness and leadership support influence DTT readiness and further lead to SCT.Originality/valueThis study contributes to the literature and knowledge by uniquely mapping and validating various interactions between DTT readiness and sustainable SC performance.

Future directions of R&D internationalization in international business
Authors: Anwar Fahim , Nujen Bella B. , Solli-Sæther Hans 
Published: June 2024

Purpose
This paper aims to provide a focused review of international business (IB) literature on research and development (R&D) internationalization, assessing the progress and proposing future research directions.

Design/methodology/approach
Total 167 peer-reviewed articles from IB journals (following the ABS list 2021 from 4* to 2) published between 1996 and 2022 are critically reviewed using a science-mapping approach. This paper used Bibliometrix R-package to analyze the retrieved bibliometric data. Additionally, a strategic diagram was developed to comprehend the maturity stage of various R&D internationalization concepts.

Findings
Most studies on R&D internationalization are influenced by perspectives from advanced-economy multinational enterprises (AMNEs), while perspectives from emerging-economy multinational enterprises (EMNEs) are underrepresented. Considering the characteristics of emerging economies, firms from these locations might embark on and develop their R&D internationalization strategies differently. Investigating the emerging economy perspectives will enrich the understanding of R&D internationalization strategies for both AMNEs and EMNEs. Additionally, bringing different underutilized theoretical perspectives will help to untangle the anomalies observed in extant literature.

Originality/value
This paper is among the few to scrutinize the IB literature on R&D internationalization by applying a unique combination of bibliometric techniques and a content analysis approach. By complementing existing reviews and providing fresh insights into the phenomenon, it offers a conceptual framework that can be used as a basis for further research on R&D internationalization.

Technology-enhanced psychological assessment and treatment of distressing auditory hallucinations: a systematic review
Authors: O’Neill Emma , Bird Molly , Riches Simon 
Published: June 2024

Purpose
Auditory hallucinations (“hearing voices”) are a relatively common experience, which is often highly distressing and debilitating. As mental health services are under increasing pressures, services have witnessed a transformative shift with the integration of technology into psychological care. This study aims to narratively synthesise evidence of technology-enhanced psychological assessment and treatment of distressing voices (PROSPERO 393831).

Design/methodology/approach
This review was carried out according to the preferred reporting items for systematic reviews and meta-analyses. Embase, MEDLINE, PsycINFO and Web of Science were searched until 30th May 2023. The Effective Public Health Practice Project (EPHPP) tool assessed methodological quality of studies.

Findings
Searching identified 9,254 titles. Fourteen studies (two assessment studies, twelve treatment studies, published 2010–2022, n = 1,578) were included in the review. Most studies were conducted in the UK, the USA or Canada. Technologies included avatar therapy, mobile apps, virtual reality, a computerised Web-based programme and a mobile-assisted treatment. Overall, technology-enhanced psychological assessments and treatments appear feasible, acceptable and effective, with avatar therapy the most used intervention. EPHPP ratings were “strong” (n = 8), “moderate” (n = 5) and “weak” (n = 1).

Originality/value
To the best of the authors’ knowledge, this is the first systematic review to investigate these technologies, specifically for distressing voices. Despite the relatively small number of studies, findings offer promising evidence for the clinical benefits of these technologies for enhancing mental health care for individuals with distressing voices. More high-quality research on a wider range of technologies is warranted.

Originality/value
This study’s originality lies in its innovative use of multilevel analysis to reveal job autonomy’s mediating role, offering fresh insights into promoting innovation and organizational in public service settings.
Competitive strategy delivery in the service sector: a study of the behavioural model
Authors: Edgar Fiona , Zhang Jing A. , Podgorodnichenko Nataliya , Akmal Adeel 
Published: June 2024

PurposeOne of the most cited literature in SHRM is Schuler and Jackson’s (1987) behavioural model. This model proposes that organisational performance is dependent on the extent to which HRM practices can be effectively connected to competitive strategy and desired employee behaviours. Importantly, this model recognises the salient role of employee behaviour in performance outcomes and, moreover that different competitive strategies imply both promulgation and reinforcement of different sets of employee skills and behaviours. Surprisingly, despite its significant influence on SHRM, studies rarely examine this model in its entirety. Motivated by the need to better understand this model’s arguments in contemporary settings, our study uses a multi-actor design to explore the connections between competitive strategies (cost reduction and differentiation), employee behaviours, and HRM practices in service environments.Design/methodology/approachAdopting a multi-level, multi-actor survey design, our exploratory deductive study assesses the utility of strategic HRM’s (SHRM) behavioural model. Drawing on data from a sample of service organisations and using univariate analyses, we compare operationalised HRM practices and employee behaviours across different strategy types.FindingsResults lend provisional support for the behavioural model, particularly in the case of a differentiation strategy where notable differences in HRM practices and employee behaviours were observed. Findings suggest growing levels of memetic and competitive isomorphism may be occurring, with this likely attributable to the increased incidence of idea generation and information sharing about best practices occurring amongst practitioners, as well as a growing nuance in operating markets, managerial preferences, employee expectations, stakeholder objectives, and the like.Research limitations/implicationsOur study suggests refinements to the behavioural model are needed. Some support for the model’s key tenets is found, but these appear context specific. Thus, the merit in developing a priori typologies linking strategy type to HRM practices and employee behaviours where organisations operate in environments which are particularised and tumultuous appears debatable.Practical implicationsThis study highlights the behavioural model’s nuance to modern service organisations and, by doing so, practitioners are provided with a behavioural pathway for achieving competitive advantage through their HRM practices. Findings also suggest that increasingly competitive environments might be encouraging practitioners to engage in isomorphic behaviours.Originality/valueThe use of a comparative research design allowed our study to contribute much needed empiricism to the largely conceptually informed stylised typologies depicting the linkages between different competitive strategies, implied employee role behaviours and HRM practices, thereby supporting the need for model refinement.
