Railway marshalling and transportation is an important component of the production supply chain for large and medium-sized enterprises in China. Traditional inefficient manual-made marshalling plans usually are not optimal in time or energy consuming. An efficient method needs to be developed to find the optimal marshalling plans automatically. This paper mainly studies the railway train automatic marshalling in large and medium-sized enterprises in China. Based on the investigation at the train station of a certain enterprise, according to the railway track information, carriage information, and production task information, this paper designs the abstracted railway state definitions of the station. Then based on the state definitions, the scheduling rules, and the objective function of time cost and economic cost, this paper converts abstract scheduling instructions into a general railway automatic marshalling model which can be executed by computers. By introducing the greedy strategies into different situations to optimize the algorithm of tracks occupation, carriages selection and train path selection in the model, the planning efficiency can be improved while ensuring the economic benefits of the enterprises and the quality of the formation plan. The experimental results show that the proposed model can generate fewer marshalling plans and find the optimal one faster in most cases, which proves the feasibility and availability of the model.

The Impact

The purpose of this research was to identify the perceptions of the local community toward tourism development impacts on Perhentian Island. Specifically, the research examined the local community’s perceptions of socio-cultural impacts, economic impacts, and environmental impacts of tourism development. The research also examined the relationship between the impacts of tourism development on the local community’s quality of life (QOL). This research was conducted using a quantitative approach by obtaining responses from 272 local community respondents on Perhentian Island. A household survey based on purposive sampling techniques was conducted to select a suitable sample. The findings of the study revealed that the positive impacts of tourism development outweighed the negative impact. Based on local community perceptions, they believed that tourism development improved their quality of life. This study also finds the impact of social-cultural benefit, economic benefits, economic cost, and environmental benefits have a significant relationship with quality of life. However, there is a negative relationship between the impact of social-cultural cost and environment cost on the quality of life. The findings of this study are important for planners and developers in planning strategic and sustainable tourism development on tourism destinations.

Globalization, prevailing trend of development of contemporary societies, inevitably influences visual and social aspects of cities. Changes of cities influenced by globalization are usually associated with increasing uniformity of residential environment, decline of public spaces, fragmentation and commercialization of urban environment. Decline of traditional territorial communities, suburbanization, gentrification, and stratification are also observed in urban societies. These processes not only influence quality of life in urban territories, but also their visual characteristics. Changes of urban environment and societies influenced by globalizing processes strongly affect city’s historic environment. Striving towards sustainable development of cities it is necessary to analyze the impacts of globalization on urban environment, historic centers and districts and to search for possibilities to use its social and economic benefits and to avoid its negative influence on city’s identity and society. The influence of globalizing processes on cities, their historic environment and societies is discussed in the paper and the proposed model for optimization of the influence of globalization on historic environment with urban design means is presented. The proposed model is applied to Kaunas historic center. Santrauka Ryškiausia visuomenių vystymosi tendencija tapusi globalizacija akivaizdžiai veikia miestų vaizdą ir visuomenes. Globalizuojančių veiksnių paskatinti miestų pokyčiai dažniausiai susiję su gyvenamosios aplinkos vienodėjimu, erdvių fragmentacija ir komercializacija. Miestų visuomenėse pastebimi tradicinių teritorinių bendruomenių nykimo, suburbanizacijos, gentrifikacijos ir išsisluoksniavimo procesai, turintys įtakos ne tik gyvenimo kokybei miestuose, bet ir jų vaizdui. Šie miestų ir visuomenių pokyčiai ryškiausiai pasireiškia per šimtmečius susiformavusiose istorinėse miestų dalyse. Siekiant darnaus miestų vystymosi, svarbu analizuoti globalizuojančių veiksnių įtaką miestams ir jų istorinėms dalims, ieškoti galimybių pasinaudoti šių veiksnių teikiama socialine-ekonomine nauda ir išvengti neigiamo jų poveikio miestų savitumui ir visuomenėms. Analizuojama globalizuojančių veiksnių įtaka miestams, jų istorinėms dalims ir visuomenėms, pateikiamos galimos globalizacijos įtakos optimizavimo istorinėje aplinkoje urbanistinės priemonės Kauno istorinio centro pavyzdžiu.

The Impact

The university is considered one of the engines of growth in a local economy or its market area, since its direct contributions consist of 1) employment of faculty and staff, 2) services to students, and supply chain links vendors, all of which define the University’s Market area. Indirect contributions consist of those agents associated with the university in terms of community and civic events. Each of these activities represent economic benefits to their host communities and can be classified as the economic impact a university has on its local economy and whose spatial market area includes each of the above agents. In addition are the critical links to the University, which can be considered part of its Demand and Supply chain. This paper contributes to the field of Public/Private Impact Analysis, which is used to substantiate the social and economic benefits of cooperating for economic resources. We use Census data on Output of Goods and Services, Labor Income on Salaries, Wages and Benefits, Indirect State and Local Taxes, Property Tax Revenue, Population, and Inter-Industry to measure economic impact (Implan, 2016).

Proposed Model

Introduction: Large-scale human-computer systems involving people of various skills and motivation into the information processing process are currently used in a wide spectrum of applications. An acute problem in such systems is assessing the expected quality of each contributor; for example, in order to penalize incompetent or inaccurate ones and to promote diligent ones.Purpose: To develop a method of assessing the expected contributor’s quality in community tagging systems. This method should only use generally unreliable and incomplete information provided by contributors (with ground truth tags unknown).Results:A mathematical model is proposed for community image tagging (including the model of a contributor), along with a method of assessing the expected contributor’s quality. The method is based on comparing tag sets provided by different contributors for the same images, being a modification of pairwise comparison method with preference relation replaced by a special domination characteristic. Expected contributors’ quality is evaluated as a positive eigenvector of a pairwise domination characteristic matrix. Community tagging simulation has confirmed that the proposed method allows you to adequately estimate the expected quality of community tagging system contributors (provided that the contributors' behavior fits the proposed model).Practical relevance: The obtained results can be used in the development of systems based on coordinated efforts of community (primarily, community tagging systems).

PurposeTo understand the football industry in its entirety, a supply chain management (SCM) approach is necessary. This includes the study of suppliers, consumers and their collaborations. The purpose of this study was to present a business management model based on supply chain management.Design/methodology/approachData were collected through in-depth interviews with 12 academic and executive football experts. After three steps of open, axial and selective coding based on grounded theory with a paradigmatic approach, the data were analysed, and a football supply chain management (FSCM) was developed. The proposed model includes three managerial components: upstream suppliers, the manufacturing firm, and downstream customers.FindingsThe football industry sector has three parts: upstream suppliers, manufacturing firm/football clubs and downstream customers. We proposed seven parts for the managerial processes of football supply chain management: event/match management, club management, resource and infrastructure management, customer relationship management, supplier relationship management, cash flow management and knowledge and information flow management. This model can be used for configuration, coordination and redesign of business operations as well as the development of models for evaluation of the football supply chain's performance.Originality/valueThe proposed model of a football supply chain management, with the existing literature and theoretical review, created a synergistic outcome. This synergy is presented in the linkage of the players in this chain and interactions between them. This view can improve the management of industry productivity and improve the products quality.

Theoretical Considerations

Managing a tourism supply chain is predominantly focused on managing a tourism-specific product that can be perceived as all kinds of goods and services utilized by tourists during their trips. The predominant goal of this article is to empirically identify the level of engagement of entities operating in the tourism-oriented branch of industry concerning the satisfaction of end-customers with the offered tourism-related services and products. Within the scope of this study, the statistical relevance of elements of active cooperation within a tourism-specific supply chain was analyzed. Empirical examinations covered the assessment of the cooperation within the framework of the tourism-oriented supply chain and its impact on consumer satisfaction. A research questionnaire was utilized to meet examination-specific goals. Theoretical considerations and the analysis of branches of industry in relation to the available statistical data showed that tourist-oriented supply chain covers various entities, the engagement of which may have a factual impact on the efficiency of managing the entire chain, as well as on the overall client satisfaction, improving tourism sustainability. The obtained results clearly showed that the examined entities considered the analyzed cooperation aspects to be very important with regard to the supply chain management. Said aspects included the total length of cooperation within the framework of a particular supply chain, which, according to the examined entities, directly translated into the quality of cooperation—to either significant or very significant extent, as well as making it much easier to solve certain problems that were strictly connected with the provision of tourism-oriented services. Yet another aspect of cooperation that was touched upon was the transfer of the so-called know-how between the entities engaged in a given supply chain. As proven by the examination, 70% of the surveyed entities claimed that it was of significant or very significant importance. The last analyzed aspect of cooperation were relations between the supply chain-specific partners and their impact on the satisfaction of end customers. According to over half of the sample (61.54%), decent relations between supply chain participants affected the satisfaction of end customers to a notable extent.
