This chapter of the book aims to introduce multiobjective linear programming (MLP) as an optimum tool to find the best quality engineering techniques (QET) in the main domains of supply chain management (SCM). The importance of finding the best quality techniques in SCM elements in the shortest possible time and at the least cost allows all organizations to increase the power of experts’ analysis in supply chain network (SCN) data under cost-effective conditions. In other words, this chapter aims to introduce an operations research model by presenting MLP for obtaining the best QET in the main domains of SCM. MLP is one of the most determinative tools in this chapter that can provide a competitive advantage. Under goal and system constraints, the most challenging task for decision-makers (DMs) is to decide which components to fund and at what levels. The definition of a comprehensive target value among the required goals and determining system constraints is the strength of this chapter. Therefore, this chapter can guide the readers to extract the best statistical and non-statistical techniques with the application of an operations research model through MLP in supply chain elements and shows a new innovation of the effective application of operations research approach in this field. The analytic hierarchy process (AHP) is a supplemental tool in this chapter to facilitate the relevant decision-making process.

Achieving better performance and a sustainable competitive advantage is essential for survival in the hotel industry. However, literature is scarce on which factors local hotel businesses in developing countries should rely on to compete successfully. With an emerging economy and significant potential for growth in the travel and hospitality sectors, Colombia is seeking to improve the performance of its hotel industry. To achieve this goal, exploring and analyzing the effects of the strategies and practices implemented is essential. Accordingly, this study investigates the dynamics of the interactions between strategies, process innovations, outsourcing practices and operational quality in the hotel industry in Colombia.

The methodology used in this research is quantitative, using structural equation modeling based on data collected from 150 valid questionnaires.

The strategies of the hotel sector have an impact on hotel performance. Although process innovation demonstrably affects quality and outsourcing, there is a low impact on the performance of the studied hotels. The hotel sector lacks strategy autonomy as strategies are not directed to the organization's overall improvement but only to satisfy stakeholders' requirements.

This paper offers valuable insights for organizations when implementing strategic innovation initiatives. It provides information relevant to Colombian government entities on the creation of processes, economic policy plans and business assistance programs for boosting the financial and commercial sustainability of Colombian service sector businesses. The studied organizations need to redefine the role of their strategies, process innovation, outsourcing projects and quality standards to achieve adequate performance, as all four dimensions together are required to foster competitiveness.

Developing successful strategies is vital to generating performance. Quality and safety are critical strategies to achieve a sustainable competitive advantage. But literature is scarce on which factors local hotel businesses should rely on to compete successfully in developing countries. In particular, the concept of outsourcing in a highly distrusting developing country has not been addressed adequately. This research contributes to literature by evaluating quality as a competitive strategy in the hotel sector in a developing country to achieve a superior performance.

Employees of Pakistani public sector organizations feel thwarted toward their goal attainment because of strict adherence to rules and regulations and tall hierarchies existing in this region. Therefore, keeping in view the harmful effects of perceived organizational obstruction, the aim of the current study was to investigate the perceived organizational obstruction as an attribution that triggers job neglect through perceived organizational frustration. Harvey’s expanded attribution-emotion model of workplace aggression and an attributional perspective on workplace aggression provide the theoretical justification. Moreover, the moderating role of self-control was proposed to mitigate the indirect effect of organizational obstruction on job neglect through perceived organizational frustration.

A three-wave data collection was done by using a close-ended questionnaire distributed to a total of 600 administrative employees of public sector organizations operating in Rawalpindi/Islamabad (Pakistan). However, matching three times and discarding the incomplete questionnaires led to a sample of 375 on which the analysis was done.

Perceived organizational obstruction positively predicted job neglect. Likewise, organizational frustration mediated the aforementioned link. Moreover, the higher level of self-control weakens this underlying process by suppressing job neglect behavior.

The current study added to the limited literature on public sector organizations that has taken perceived organizational obstruction as a predictor variable. Moreover, this study explains how this phenomenon translates into non-hostile behavior that is difficult to identify and punish in public sector organizations. Moreover, the trait of self-control is added to the literature of non-hostile behaviors that dampen the impulsivity to indulge in job neglect.

The objective of this study is to examine current business and management research on “Industry 4.0 base technologies” and “business models” to shed light on this vast literature and to point out future research agenda.

The authors conducted a bibliometric analysis of scientific publications based on 482 documents collected from the Scopus database and a co-citation analysis to provide an overview of business model studies related to Industry 4.0 base technologies. After that a qualitative analysis of the articles was also conducted to identify research trends and trajectories.

The results reveal the existence of five research themes: smart products (cluster 1); business model innovation (cluster 2); technological platforms (cluster 3); value creation and appropriation (cluster 4); and digital business models (cluster 5). A qualitative analysis of the articles was also conducted to identify research trends and trajectories.

First, the dataset was collected through Scopus. The authors are aware that other databases, such as Web of Science, can be used to deepen the focus of quantitative bibliometric analysis. Second, the authors based this analysis on the Industry 4.0 base technologies identified by Frank et al. (2019). The authors recognize that Industry 4.0 comprises other technologies beyond IoT, cloud computing, big data and analytics.

Drawing on these analyses, the authors submit a useful baseline for developing Industry 4.0 base technologies and considering their implications for business models.

In this paper, the authors focus their attention on the relationship between technologies underlying the fourth industrial revolution, identified by Frank et al. (2019), and the business model, with a particular focus on the developments that have occurred over the last decade and the authors performed a bibliometric analysis to consider all the burgeoning literature on the topic.

Service managers increasingly strive to achieve sustainability through strategies centered on circularity. With a focus on saving, extending and (re)generating resources and their enclosing service systems, circularity can contribute to environmental, social and financial gains. Yet, the notion of circularity is surprisingly understudied in service research. This article seeks to provide an initial conceptual understanding of circular service management, introducing illustrative strategies and research priorities for circular service management. This paper provides a roadmap for scholars, practitioners and policymakers to develop a deeper understanding of the opportunities from adopting circular services.

The authors explore the concept of circular service management by drawing upon existing literature on sustainability, circularity and service research. Strategies of circular service management and research priorities emerge on the basis of industry best practice examples and research on sustainability challenges and opportunities.

Service researchers have largely ignored the concept and role of circularity for service businesses. Extant research on the topic nearly exclusively features in non-service journals and/or does not seek to advance service theory through circularity. This article argues that circular service management enables the implementation of service thinking in the pursuit of sustainability and outlines four types of circular service management strategies.

The authors introduce the concept of circular service management and highlight the role of service research for designing and managing circular systems and operations. This article also offers a research agenda connecting managerial challenges and opportunities with key service research priorities for circular service management. This provides a roadmap for scholars, practitioners and policymakers to develop a deeper understanding of pursuing circular services, thereby contributing to a more sustainable future.

The purpose of this paper is to provide an overview of the antimicrobial and antioxidant properties of postbiotics and the use of postbiotics to increase the shelf life and quality of food.

In this review paper, all articles from five electronic databases containing Google Scholar, Web of Science, PubMed, Scopus and Science Direct were considered and selected according to the purpose of the study.

In addition to improving food safety and increasing its shelf life, natural food preservation using biological preservatives also has a positive effect on improving consumer health. As a result, protection using natural antioxidants and antimicrobial agents seems essential. Postbiotics, having favorable characteristics such as nontoxicity, long shelf life and ease of standardization and transportation, are known as suitable antioxidant and antimicrobial, and there is an interest in making antioxidant and antimicrobial active films containing postbiotics to delay spoilage, increase the shelf life of perishable foods without changing their sensory characteristics.

Postbiotic refers to all soluble factors that are either secreted from living probiotic cells or released after cell lysis. These compounds include enzymes, peptides, polysaccharides, organic acids, teichoic acids and cell surface proteins, and their effects have been proven to improve some human and animal diseases. Probiotic bacteria must survive unfavorable conditions such as processing, storage, distribution, preparation and the digestive system to exert their health-giving effects, whereas their metabolites (postbiotics) have overcome these adverse conditions well and may be a good substitute for probiotics.

The aim of this paper is to identify the main challenges and limitations of current business process management (BPM) development directions noticed by researchers, as well as to define the areas of the main BPM paradigm shifts necessary for the BPM of tomorrow to meet the challenges posed by Industry 4.0 and the emerging Industry 5.0. This is extremely important from the perspective of eliminating the existing broadening gap between the considerations of academic researchers and the needs of business itself.

A systematic literature review was conducted on the basis of the resources of two digital databases: Web of Science (WoS) and SCOPUS. Based on the PRISMA protocol, the authors selected 29 papers published in the last decade that diagnosed the challenges and limitations of modern BPM and contained recommendations for its future development. The content of the articles was analyzed within four BPM core areas.

The authors of the selected articles most commonly point to the areas of organization (21 articles) and methods and information technology (IT) (22 articles) in the context of the challenges and limitations of current BPM and the directions of recommended future BPM development. This points to the prevalence among researchers of the perspective of Industry 4.0 – or focus on technological solutions and raising process efficiency, with the full exclusion or only the partial signalization of the influence of implementing new technologies on the stakeholders and in particular – employees, their roles and competencies – the key aspects of Industry 5.0.

The proposal of BPM future development directions requires the extension of the BPM paradigm, taking into account its holistic nature, especially unpredictable, knowledge-intensive business processes requiring dynamic management, the need to integrate BPM with knowledge management (KM) and the requirements of Industry 5.0 in terms of organizational culture. The limitation is that the study is based on only two databases: WoS and SCOPUS and that the search has been narrowed down to publications in English only.

The proposal of BPM future development directions also requires the extension of the BPM paradigm, taking into account the specific challenges and limitations that managers encounter on a daily basis. The presented summaries of the challenges and limitations resulting from the literature review are accompanied by recommendations that are primarily dedicated to practitioners.

The article indicates the area people and culture as one of the four core areas of BPM. It emphasizes the necessity to account to a greater degree for the influence of people, their knowledge, experience and engagement, as well as formal and informal communication, without which it is impossible to use the creativity, innovativeness and dynamism of the individual and the communities to create value in the course of business process execution.

To the authors' knowledge, this is the first systematic review of the literature on the limitations of modern BPM and its future in the context of Industry 4.0 and Industry 5.0.

The purpose of this study is to introduce new tools to develop a more precise and focused bibliometric analysis on the field of digitalization in healthcare management. Furthermore, this study aims to provide an overview of the existing resources in healthcare management and education and other developing interdisciplinary fields.

This work uses bibliometric analysis to conduct a comprehensive review to map the use of the unified theory of acceptance and use of technology (UTAUT) and the unified theory of acceptance and use of technology 2 (UTAUT2) research models in healthcare academic studies. Bibliometric studies are considered an important tool to evaluate research studies and to gain a comprehensive view of the state of the art.

Although UTAUT dates to 2003, our bibliometric analysis reveals that only since 2016 has the model, together with UTAUT2 (2012), had relevant application in the literature. Nonetheless, studies have shown that UTAUT and UTAUT2 are particularly suitable for understanding the reasons that underlie the adoption and non-adoption choices of eHealth services. Further, this study highlights the lack of a multidisciplinary approach in the implementation of eHealth services. Equally significant is the fact that many studies have focused on the acceptance and the adoption of eHealth services by end users, whereas very few have focused on the level of acceptance of healthcare professionals.

To the best of the authors’ knowledge, this is the first study to conduct a bibliometric analysis of technology acceptance and adoption by using advanced tools that were conceived specifically for this purpose. In addition, the examination was not limited to a certain era and aimed to give a worldwide overview of eHealth service acceptance and adoption.

Despite the increasing relevance of seamless shopping experience in an omnichannel context, research on how seamless shopping experience affects customers’ word of mouth on social media (sWOM) remains scant. Based on the attribution theory, this study aims to investigate the effects of seamless shopping experience types on customers’ sWOM intentions from the perspective of smart-shopping feelings and validated the moderation role of shopping orientation.

Using a data set of 301 omnichannel customers, three scenario-based experiments were conducted to address the research questions.

An efficient and interconnected experience is more likely to positively affect sWOM intentions than an inefficient but interconnected experience. Furthermore, smart-shopping feelings were found to have a significant mediating effect. For experiential-oriented shoppers, the positive relationship between an efficient and interconnected experience, smart-shopping feelings and sWOM intentions was significantly strengthened.

This research contributes to the sWOM and omnichannel service experience literature by investigating the influences of seamless shopping experience types on customers’ sWOM intentions. This research also provides recommendations for designing and delivering a superior, seamless shopping experience for omnichannel shoppers.
