Abstract

Purpose

This paper aims to propose an operation policy of multi-capacity room service robots traveling within a hotel. As multi-capacity robots can serve many requests in a single trip, improved operation policy can reduce the investment cost of robots.

Design/methodology/approach

Using a mathematical model-based optimization technique, an optimal set of robots with minimum installation cost is derived while serving the entire room service demands. Through testing a variety of scenarios by changing the price and function of robots to be installed, insights that consider the various situations are offered.

Findings

Though the increase in capacity saves much time for room service at a lower capacity level, the amount of time saved gradually decreases as the capacity increases. Besides, the installation strategy is divided into two cases depending on the purchase cost of robots.

Research limitations/implications

Currently, the studies focusing on the adoption of service robots from an operations view are rarely be found. To reduce the burden of investment cost, this study takes the unique approach to improve the operation policy of service robots by using the multi-capacity robots.

Practical implications

This study guides the hotel to install an adequate set of robots. The result confirms that the optimal installation set of robots is affected by various factors, such as the room service information, the hotel structure and the unit execution cycle.

Originality/value

After the outbreak of COVID-19, people avoid face-to-face contact and interest in non-contact service is growing. This paper deals with the efficient way to implement non-contact delivery through logistic robots, a timely and important topic.

Abstract

Purpose

This study investigates the pricing and inventory control decisions of a company that owns a coffeehouse chain providing drip coffee and a coffee manufacturing factory producing ready-to-drink (RTD) coffee. To determine a way to maximize profit, optimal pricing and inventory control strategies are studied for both the RTD coffee as well as the coffeehouse chain network.

Design/methodology/approach

It is assumed that the company sells only drip coffee through its coffeehouse chain and would like to launch RTD coffee via other channels such as convenience stores, supermarkets and so on to maximize its total profit. A mathematical model–based optimization is adopted to address the decision-making for the given problem situation, where the demand for both drip and RTD coffee are dependent on the values of decision variables. To solve the proposed mathematical model, particle swarm optimization (PSO) is applied due to nonlinearity of the developed model.

Findings

It is confirmed that a company can earn more profit by launching RTD coffee, even though the profit from drip coffee would reduce. In addition, the scenario analysis shows that by launching RTD coffee under various conditions, the total profits would also improve.

Originality/value

The value of this study is the proposed basic framework for the industry. In addition to the modeling framework and cost structure, realistic cost figures and technical details can be considered when applying the model to a practical setting.

Abstract

Purpose

In the tourism industry, unmanned aerial vehicles (UAVs) can perform monitoring and patrol missions to protect assets and tourists at attractions such as coastal areas, canyons, national parks, etc. Such use of UAVs can improve safety and security of tourism attraction and facilitate tourism industry. However, there is a key issue regarding economic investment and efficient operation for actual system implementation. The purpose of this paper is to provide a guideline for supporting economic investment and the efficient operation of UAV system in the tourism industry.

Design/methodology/approach

Ideas and methodologies have been proposed to overcome the fundamental limitations of commercial UAVs. A mathematical optimization model is developed to determine the optimal number of UAVs to be purchased, and its operation schedules simultaneously.

Findings

Using proposed concept and methodology, UAVs can support long duration of missions. Economic system design as well as the operation schedule is derived with the hypothesis data in Kkot-Ji beach in Korea. The proposed methodology and approach is expected to have huge potential at many tourism attractions to achieve the safety and security of tourists.

Practical implications

The result of this study can facilitate practical use of UAVs in the tourism industry. Furthermore, it is applicable in many industries that need UAV systems such as national defence, agriculture, disaster management, etc.

Originality/value

The proposed study suggests a solution to handle fundamental weakness of UAVs and support long duration of missions. In addition, this study incorporates economic system design issue and operation issue simultaneously.

Abstract

Purpose

This study aims to disclose the antecedent factors for predicting support for cruise tourism in the Bahamas. It investigated the relationship between residents’ support for cruise tourism and the four indicators that were the positive/negative impact of cruise tourism on the community, perceived conflicts in sharing information and concerns about the COVID-19 pandemic.

Design/methodology/approach

Using 278 surveys of local residents near major cruise ports in the Bahamas, this study identified the salient variables in tourism impact and conflict factors. The survey questionnaire was adapted and developed from relevant studies and modified to suit the context of cruise tourism.

Findings

The results revealed that residents’ perceived conflict was insignificantly associated with their support for cruise tourism. In contrast, their concerns about COVID-19 and perceptions of the positive and negative cruise tourism impacts were statistically significant in predicting the likelihood of support for tourism.

Originality/value

This study suggests implications for enhancing the long-term growth of the cruise industry, which is vulnerable to environmental threats such as Covid-19.

Abstract

This paper, in face of the increasing interconnectivity between local and global, has attempted to retrospect the critical moment of Korean society under Tae‐woo Rho (1988–93) regime, in which Korea struggled for fundamental reforms of the earlier centrally controlled state system through economic rationalization and labor flexibilization. During that juncture of Korean history, neo‐liberalization under the influence of Fordian decline was a governing theme behind the Korean economy's policy formation as well as labor agenda. This reliance of government on the neo‐liberal pillar has made an impact on the subsequent leaderships under Young Sam Kim (1993–1998) and Dae Jung Kim (1998‐present). After briefly reviewing the major aspect of Korean economy and labor problems surrounding the financial crisis of East Asia around 1998, the international influence of Fordian decline and neo‐liberalization as a Korean alternative has been discussed.

Abstract

Purpose

The purpose of this paper is to explore the possibilities of prioritizing tasks, actual sharing of libraries, collaboration policies and the directions via quantifying the relative importance of services for each value based on users’ perceptions observed from in-depth analysis of the investigation results. Through this, the study expects that libraries will provide high – level the sharing economy services, reflecting users’ needs.

Design/methodology/approach

This study surveyed public library users across the country have through the survey method and Analytic Hierarchy Process (AHP) method to examine the perceptions of users on the roles of libraries in the sharing economy’s environment to deduce the directions and priorities to activate the roles and functions of libraries in the era of the sharing economy.

Findings

The research results are as follow: first, public library users’ awareness of the concept of the sharing economy was low, but they observed a relation between the two concepts after understanding the concept of the sharing economy. Second, The users’ personal characteristics were observed to mostly affect knowledge information service, experience talent sharing, material sharing and space sharing. Lastly, the study sought to identify the relative importance (preference) of various library services which pursue the value of the sharing economy through AHP analysis method. The values of the sharing economy were preferred in the order of social>economic>technical>relational values which can be enumerated to convenience>knowledge>space>education>contents>new technology>experienced talent>object>network.

Originality/value

This study has a great significance in that it analyzed actual library users’ perceptions on the concept of the sharing economy and the functions and roles of libraries in the era of the sharing economy from a multifaceted angle. In addition, this study carries an important meaning as it provided an opportunity to vitalize libraries and explored the measures to actualize the roles of libraries in tandem with the environment of the sharing economy by recognizing the values of libraries based on the new concepts and values of the sharing economy and presenting the functions and roles of the libraries from the aspects of the sharing economy.

Abstract

Purpose

Emojis are quickly becoming a popular new language in social media and marketing. The capability to express emotions and make message understanding easier is one of the primary reasons for using emojis. The aim of this research was to determine the influence of perceived usefulness, perceived ease of use, trust, and involvement on customer engagement due to emojis used in digital marketing communications among Generation Z (Gen Z) in South Africa.

Design/methodology/approach

Following the descriptive research approach, quantitative research was used in this study. A questionnaire (self-administered) was utilized to test the effectiveness of using emojis among 1,000 young consumers. Structural equation modeling was used to test the hypotheses.

Findings

The findings of the study yielded positive relationships between the variables, namely between trust and involvement; involvement and the perceived ease of use; involvement and perceived usefulness; perceived ease of use and perceived usefulness; trust and customer engagement; perceived usefulness and customer engagement; involvement and customer engagement; customer engagement and intention to purchase; trust and intention to purchase; and perceived usefulness and intention to purchase.

Practical implications

This study can help organizations in emerging markets use emojis in their digital marketing communications to engage customers and stimulate intention to purchase among young people, especially the Gen Z cohort, who seek organizations and brands that understand and connect with them.

Originality/value

By investigating the effects of emojis in digital marketing communications, this study contributes to the customer-centric process and the literature on emoji usage while also involving a credible digital language when communicating with members of Gen Z. By extending TAM, the findings of this study contribute to the TAM literature by demonstrating that emoji usage in digital marketing communications positively influences various attitudinal associations among Gen Z consumers.

Abstract

This paper proposes a new theoretical framework to explain enterprise unionism and conducts the first systematic comparative study of union structure in nine Asian countries. Our framework emphasizes political dynamics and the role of the state in labor relations and argues that the initial period of the collective bargaining era constituted a critical juncture (state labor policy) that occurred in distinctive ways in different countries and that these differences played a central role in shaping the different union structures in the following decades. The nine countries are mainly divided into three groups, depending on the type of state labor policy: enforcement of enterprise unionism; centralization/laissez-faire (non-enterprise unionism); and dual unionism/gradual transition (middle-ground). Governmental data were used for the study. A clear correspondence between state labor policy and union structure in each of these groups was found. We believe that our framework significantly enhances our understanding of the Asian cases. Future research should explore the validity of the proposed framework through comparative studies of Latin American cases where enterprise unions have also been observed.

Abstract

Globalisation is generally defined as the “denationalisation of clusters of political, economic, and social activities” that destabilize the ability of the sovereign State to control activities on its territory, due to the rising need to find solutions for universal problems, like the pollution of the environment, on an international level. Globalisation is a complex, forceful legal and social process that take place within an integrated whole with out regard to geographical boundaries. Globalisation thus differs from international activities, which arise between and among States, and it differs from multinational activities that occur in more than one nation‐State. This does not mean that countries are not involved in the sociolegal dynamics that those transboundary process trigger. In a sense, the movements triggered by global processes promote greater economic interdependence among countries. Globalisation can be traced back to the depression preceding World War II and globalisation at that time included spreading of the capitalist economic system as a means of getting access to extended markets. The first step was to create sufficient export surplus to maintain full employment in the capitalist world and secondly establishing a globalized economy where the planet would be united in peace and wealth. The idea of interdependence among quite separate and distinct countries is a very important part of talks on globalisation and a significant side of today’s global political economy.
