Abstract
Purpose
With the rapid development of e-commerce, logistics demand is increasing day by day. The modern warehousing with a multi-agent system as the core comes into being. This paper aims to study the task allocation and path-planning (TAPP) problem as required by the multi-agent warehouse system.
Design/methodology/approach
The TAPP problem targets to minimize the makespan by allocating tasks to the agents and planning collision-free paths for the agents. This paper presents the Hierarchical Genetic Highways Algorithm (HGHA), a hierarchical algorithm combining optimization and multi-agent path-finding (MAPF). The top-level is the genetic algorithm (GA), allocating tasks to agents in an optimized way. The lower level is the so-called highways local repair (HLR) process, avoiding the collisions by local repairment if and only if conflicts arise.
Findings
Experiments demonstrate that HGHA performs faster and more efficient for the warehouse scenario than max multi-flow. This paper also applies HGHA to TAPP instances with a hundred agents and a thousand storage locations in a customized warehouse simulation platform with MultiBots.
Originality/value
This paper formulates the multi-agent warehousing distribution problem, TAPP. The HGHA based on hierarchical architecture solves the TAPP accurately and quickly. Verifying the HGHA by the large-scale multi-agent simulation platform MultiBots.

Purpose
This study aims to develop a measurement scale of tourism-led rural gentrification from the perspective of rural residents.
Design/methodology/approach
The procedure for developing the measurement scale included a thorough review of related literature on tourism-led rural gentrification and multiple stages of qualitative and quantitative investigations. A total of 1,080 rural residents in Huzhou and Huangshan participated in the project. The semi-structured interviews and questionnaire were applied to collect the data. This study analyzed the data with the methodologies of exploratory factor analysis, confirmatory factor analysis and structural equation modeling.
Findings
The measurement scale developed in this study included seven dimensions: Accelerated Ecological Awareness, Individual Behavior, Rural Economic Development, Enhanced Living Standards, Talents and Demographic Changes, Human and Cultural Shift and Cohesive Community.
Research limitations/implications
This measurement scale was developed and validated in China and may not be relevant in other contexts. The scale focuses on tourism-led rural gentrification only from the perspective of rural residents. The findings broaden the knowledge on tourism-led rural gentrification by researching the topic from the point of view of rural residents.
Practical implications
For policymakers and tourism enterprises, this study provides a valuable index for a full understanding of tourism-led rural gentrification. For investors, the research offers insights for priority investments to advance tourism development in rural regions.
Originality/value
This study is one of the few attempts to empirically measure tourism-led rural gentrification. The results improve on the knowledge about tourism-led rural gentrification in China.

Abstract
Purpose
The purpose of this paper is to comprehensively review the sources of competitive strength of emerging market multinationals (EMMs). Since most lack firm-specific assets such as internalized knowledge or globally recognized brands, especially in their early international growth, and emanate from less-developed nations, the success of EMMs has to be explained by identifying factors in their home nations and international scope which make these firms internationally competitive.
Design/methodology/approach
A comprehensive review of the extant literature and company cases identified several sources of competitive advantage for emerging market firms. Since conclusive evidence is still unavailable, many of these factors are proposed as hypotheses for future empirical research. Where needed, contrary viewpoints are also discussed and cited.
Findings
This paper identifies several possible location-specific assets of emerging market companies including the mindset of top management of EMMs (such as long term orientation, global or cosmopolitan perspectives, a degree of humility that recognizes the need to catch-up by learning from foreign allies and customers, tolerance for ambiguity, and frugality) and home country cultural traits such as emphasis on relationships, family control, and private equity capital. Other sources of competitiveness may lie in the home country pool of technical talent and cheap labor, the extensive diasporas of persons of Chinese, Indian and Brazilian origin, and the role of common language as determinants for the geographical pattern of FDI from emerging nations.
Originality/value
This paper serves the dual purpose of providing a comprehensive literature review of this topic for doctoral or Masters students, and specifying hypotheses (as well as opposing views) for further investigation.

Abstract
Purpose
This study, a narrative literature review, aims to examine the combined benefits of the active and passive use of social media (SM) for well-being (WB), physical and mental health during the COVID-19 pandemic.
Design/methodology/approach
A search strategy has been carried out in the databases: Riss, PubMed, Medline, Scopus and Google Scholar, including all the articles published until 19 October 2023.
Findings
SM offers various benefits, including global risk awareness, health information, social connections and support. With the natural increase in physical inactivity due to COVID-19 social restrictions, SM has been identified as an appropriate tool for promoting physical activity (PA) at home to improve health.
Research limitations/implications
It suggests that the combined use of active and passive benefits of SM could potentially play an important role in public health by increasing individuals’ health behaviours. In addition, dissemination, sharing and social interaction of information provided by YouTube can encourage healthy behaviours, contribute to WB, physical and mental health and raise public health awareness.
Originality/value
The findings presented in this study highlight the combined benefits of differentiating the features of SM use. Compared to other SM platforms, YouTube can be used as a useful tool for home-based PA that promotes health by enabling people to remain active and avoid barriers to PA due to social restrictions during the global crisis. In addition, some recommendations from the findings may help protect against potential risks and improve public health outcomes during global crises, such as the COVID-19 pandemic, among the general public using SM.
