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.

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.

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.

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.

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.

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.

The purpose of this study was first to examine how goal-oriented attendees and experiential-oriented attendees were related with their overall satisfaction and loyalty of the destination with respect to international food and wine festival. It also investigated how these relations are mediated by different dimension of experiential consumption values such as consumer return on investment (CROI, active value), escapism (active value) and service excellence (reactive value) and aesthetics (reactive value).

Self-administered questionnaires were distributed to and collected from attendees at the 2011 Food Network South Beach Wine and Food Festival in Miami, Florida. A total of 450 subjects were collected from attendees indicating a response rate of about 88 per cent. Total 13 hypotheses were tested using structural equation model (SEM) with AMOS, and the results were interpreted adapting Mathwick’s (2001) typology of experiential value.

The findings indicate that goal-oriented attendees had stronger relationship with reactive experiential values such as service excellence and aesthetics than active values, whereas experiential-oriented attendees had more significant relations with active experiential values such as CROI and escapism than reactive values. In addition, CROI, escapism and service excellence were found to have a positive influence on the overall satisfaction with the festival; in turn, the attendees’ satisfaction had a positive effect on their intention to revisit the destination. Further, the results demonstrated that all experiential values, including CROI and escapism (active values), and service excellence and aesthetics (reactive values), played a mediating role between goal-oriented/experientially oriented attendee and satisfaction with the festival.

The festival organizers and managers should understand what drives the attendees’ participation in the festival. Implementing experiential marketing through various dimensions of experiential value can attract more potential attendees, provide unique experiences and create favorable perception toward the destination.

The research is original in terms of conceptualizing and empirically testing the relation between experiential consumption values and behavior loyalty within the special events and festivals with a specific focus on international food and wine festival. A finding of particular importance here is verifying the unique characteristics of goal-/experiential-oriented attendees in festival settings and determining the linkages between these different attendees and active/reactive experiential values, not to mention the relation with the overall satisfaction and loyalty to the festival destination.

Local events play a significant role in rebuilding relationships and increasing engagement with local communities in the postpandemic. This study aims to investigate how potential attendees’ usage of local event hashtags facilitates social media engagement, further enhancing their intentions to attend local events.

This study adopted an exploratory sequential mixed approach. The qualitative phase used 12 semistructured in-depth interviews to explore motivations for hashtag usage and developed instruments to measure hashtag usage and social media engagement. The quantitative phase examined the relationship among motivations and behaviors of hashtag usage, social media engagement and behavioral intention through 522 online surveys.

Qualitatively, four themes manifest in hashtag users’ motivations in the context of local events: self-promoting, searching, summarizing and conforming. The quantitative findings show that these motivations influence active and passive hashtag usage differently, leading to different types of social media engagement (i.e. persistent, customized and triggered engagement). All social media engagements can significantly enhance the intention to attend local events.

This study divides active and passive hashtag users, conceptualizes social media engagement through hashtag usage under the affordance approach and develops instruments for these concepts. It emphasizes the importance of hashtag usage that drives social media engagement and provides insights for local event planners.

Recent wireless communication and electronics technology has enabled the development of low‐cost, low‐power, and multi‐functional sensor nodes. However, the fact that sensor nodes are severely energy‐constrained has been an issue and many energy‐efficient routing protocols have been proposed to resolve it. Cluster‐based routing protocol is one of them. To achieve longer lifetime, some cluster‐based routing protocols use information on GPS‐based location of each sensor node. However, because of high cost, not all sensor nodes can be GPS‐enabled. The purpose of this paper is to propose a simple dynamic clustering approach to achieve energy efficiency for wireless sensor networks (WSN).

Instead of using location information of each sensor node, this approach utilizes information of remaining energy of each sensor node and changes in the number of cluster head nodes dependent on the number of sensor nodes alive. Performance results are presented and compared with some related protocols.

The simulations described in the paper show that both residual energy of each sensor node and changing cluster head nodes depending on the number of sensor nodes alive are very critical factors to obtain performance enhancement in terms of lifetime and data transmission. Especially, in some special environment, the proposal has better performance than GPS‐enabled protocol.

The paper is of value in proposing a simple dynamic clustering approach to achieve energy efficiency for WSN.

This study compares the applicability of the zone of tolerance and importance-performance analysis (IPA) techniques in the evaluation of convention delegates’ perceptions of products and services. Overall, 217 cases out of 400 were used for analysis, a response rate of 54 percent. The study results indicate that although an IPA technique is still useful in assessing the service performance of a convention facility, IPA should be employed with caution, concrete criteria, and clear goals. The study results also show that the zone of tolerance is practically applicable into business practice to assess service performance item by item.

The purpose of this study is three fold: to provide a preliminary exploration of meeting planners' use and perceived usefulness of the different types of social media; to examine why meeting planners use social media and; to investigate the perception of adopting the social media, especially as perceived critical mass impacts the adoption of social networking media.

Data were collected from the members of a professional association for meeting professionals in the Southwest US using an online self‐administered questionnaire. A total of 510 members received an invitation to take the survey and 120 responses were received, representing a 23.5 percent response rate. Descriptive analysis, discriminant validity, reliability and path analysis were used to estimate the relationships between the five constructs: perceived critical mass, usefulness, ease of use, attitudes and intention to use social network media in the future.

The most commonly preferred social network sites were Facebook (29 percent), LinkedIn (15 percent), YouTube (13 percent), Twitters (11 percent) and My Space (11 percent) and the social networking media rated most useful were Facebook (mean=3.7), LinkedIn (mean=3.1), YouTube (mean=3.0), Blogs (mean=2.7), Webinars (mean=2.6) and Twitter (mean=2.5), The top three reasons for using social media were: to communicate with other planners easily and quickly through chat or discussion boards (80.4 percent), to share queries, problems, solutions and opinions with other meeting planners (70.1 percent) and to get feedback from attendees after meeting/event/convention (69.9 percent). Additionally, the path model used in the analysis indicated that perceived critical mass not only directly influences intention to use social network media but also indirectly affects attitude toward using social media and intention to use social media simultaneously through perceived ease of use and perceived usefulness.

Even though the social networking media has previously been used by many meeting planners to find information, few research studies have explored the meeting planners' perception of social networking media and what factors may have an effect on meeting planners' adoption of using social network media. This study provides a preliminary empirical analysis of meeting planners' perception of these tools and the factors that influence their utilization.
