Multi-agent system application in accordance with game theory in bi-directional coordination network model

The multi-agent system is the optimal solution to complex intelligent problems. In accordance with the game theory, the concept of loyalty is introduced to analyze the relationship between agents' individual income and global benefits and build the logical architecture of the multi-agent system. Besides, to verify the feasibility of the method, the cyclic neural network is optimized, the bi-directional coordination network is built as the training network for deep learning, and specific training scenes are simulated as the training background. After a certain number of training iterations, the model can learn simple strategies autonomously. Also,as the training time increases, the complexity of learning strategies rises gradually. Strategies such as obstacle avoidance, firepower distribution and collaborative cover are adopted to demonstrate the achievability of the model. The model is verified to be realizable by the examples of obstacle avoidance, fire distribution and cooperative cover. Under the same resource background, the model exhibits better convergence than other deep learning training networks, and it is not easy to fall into the local endless loop.Furthermore, the ability of the learning strategy is stronger than that of the training model based on rules, which is of great practical values.

Multi-ACO Application in Routing and Scheduling Optimization of Maintenance Fleet (RSOMF) Based on Conditions for Offshore Wind Farms

Reducing the operation and maintenance (O & M) cost is one of the potential actions that could reduce the cost of energy produced by offshore wind farms. This article attempts to reduce O & M cost by improving the utilization of the maintenance resources, specifically the efficient scheduling and routing of the maintenance fleet. Scheduling and routing of maintenance fleet is a non-linear optimization problem with high complexity and a number of constraints. A heuristic algorithm, Ant Colony Optimization (ACO), was modified as Multi-ACO to be used to find the optimal scheduling and routing of maintenance fleet. The numerical studies showed that the proposed methodology was effective and robust enough to find the optimal solution even if the number of offshore wind turbine increases. The suggested approaches are helpful to avoid a time-consuming process of manually planning the scheduling and routing with a presumably suboptimal outcome.

The Research of Customer Loyalty Improvement in Telecom Industry Based on NPS Data Mining

In recent years, the telecommunications have used the concept of NPS(Net Promoter Score) for customer relationship management, but there is neither definite theory research nor instructive instance research. However, this paper summarizes an approach with instance case analysis to improve customer loyalty via NPS data mining, which has extensive and practical significance for tele-companies. First, this paper finds some driven forces of customer loyalty, which are relative to customer consumption such as the call duration, the usage of data, ARPU, etc., by using some innovative reasoning-analysis based on IG(Information Gain) and xg-boost decision-making tree model, so the tele-companies can predict the role of individual customer and form daily monitoring on big data, which will save a lot of NPS survey cost. Second, this paper summarizes how customer group feature impacts the relationship between NPS and financial performance. Taking ARPU value as the performance goals, we divide the sample customers into 6 groups and summarize their characteristics based on k-means clustering, and give targeted suggestion of each group.

Reconstructing Dual Loyalties:Interaction between Host States' Perception and Diasporas' Reaction

This article explores the dynamics of the Diaspora's dual loyalties towards their home countries and host countries by using American Jewry as a case study. It argues that in liberal-democratic states,the shift in the Diaspora's loyalty towards the homeland vis-à-vis the host land is a result of the change to the host land's perception of where the acceptable boundary of the Diaspora's practice of dual loyalties is, or in other words, to what extent the Diaspora's support of the homeland is perceived to be acceptable by their host land. The reconstruction of this boundary is determined by four factors: the degree of political coordination between home states and host states, the attempt of the home state to mobilize its diasporas, the means advocated and supported by the Diaspora, and the severity of potential consequences due to the Diaspora's action.

The Effects of B2C Interaction on Customer Loyalty

Purpose： This research attempts to examine the relationship between B2C interaction and customer loyalty in Business-to-Customer（B2C） context from a new perspective of the interactive tool.Design/methodology/approach： The scale for B2C interactive tools is of seven dimensions： efficiency, security, fulfillment, mobility, community, cultivation, and customization. A model reflecting the influences of these attributes on customer loyalty is developed and empirically examined based on data collected from 265 B2C customers. Findings： Results reveal that the fulfillment, mobility, community, and customization of B2C interactive tools can enhance customer loyalty directly and significantly. Efficiency and security, serving as the premise for possible purchase behavior, facilitate fulfillment. In addition, cultivation promotes the formation of customization, which directly strengthens customer loyalty.Research limitations： Models considering individual-level indicators and combined with classic loyalty mechanisms in B2C context may lead to a deeper understanding of the tested effects of interaction on customer loyalty.Practical implications： To strengthen B2C interaction and further cultivate loyal customers, making interactive tools more fundamental, flexible, and personalized is critical for B2C enterprises. Originality/value： This study proposes a new perspective from interactive tools when measuring the relationship between B2C interaction and customer loyalty, and offers a useful theoretical lens and reasonable explanations for investigating customer loyalty in B2C e-commerce context.

Global mobile communication is one of the most dynamic and important service markets.Several researchers suggest using a theoretical approach to develop a much deeper insight into key marketing constructs,such as service quality,customer perceived value,customer satisfaction,perceived switching costs,corporate image,and customer loyalty,is vital to the mobile communications market.This paper aims to investigate the role of service quality,trust,and perceived value on calculative commitment and loyalty intention in the customers of mobile telephone network service providers(MTNSPs).To notify the meaningful factors for the calculative commitment and loyalty intention of the users in using mobile phones,this study focuses on the effect of service quality and perceived value in the trust and identifying the role of trust in forming customer loyalty.As many as 125 users of mobile phone users—house wife were surveyed in Coimbatore,Tamil Nadu,India.The data are analyzed by path analysis.This study shows that service quality has a direct and positive effect on trust,trust has a direct and positive effect on calculative commitment,calculative commitment has a direct and positive effect on loyalty,and direct and positive relationship between perceived value and calculative commitment,perceived value,and loyalty are also confirmed.In terms of mobile telecommunication systems,it is found that the users may exhibit noticeable differences in using this service.This study provides important hints to strengthen the relationship between the network service providers and their customers.

The complicated life of a physician-soldier: Medical readiness training exercises &the problem of dual loyalties

While physicians are generally understood as owing moral obligation to the health and well being of their individual patients, military health professionals can face ethical tensions between responsibilities to individual patients and responsibilities to the military mission. The conflicting obligations of the two roles held by the physician-soldier are often referred to as the problem of dual loyalties and have long been a topic of debate. This paper seeks to enrich the dualloyalties debate by examining the embedded case study of medical civilian assistance programs. These programs represent the use of medicine within the military for strategic goals. Thus, a physician is expected to meet his obligation to his role as a soldier while also practicing medicine. These programs involve obligations inherent in both roles of the physician-soldier and thusly they serve as excellent exemplars for the problem of dual loyalties at an institutional level. This paper focuses on Medical Readiness Training Exercises (MEDRETEs). These programs are short-term, generally taking place in low-income nations in order to accomplish strategic goals including training opportunities for military medical professionals that are not possible on the home front. This form of temporary program raises ethical concerns regarding the exploitation of vulnerable populations and the value of what is termed “parachute medicine”. The short-term nature of these interventions makes long-term treatment and follow-up impossible, begging the question as to whether this peak and trough approach to foreign civilian aid is of any use. Physicians are generally understood as having obligations towards the well being of the patient, which these programs do not necessarily prioritize. Rather, the programmatic intent is military, with political and strategic aims of furthering international relations, increasing US military global presence and providing austere and tropical training opportunities for military healthcare providers. This can be morally problematic for the physician-soldier.

Customer Loyalty： An Empirical Study on Italian E-commerce Websites

In contemporary entrepreneurial environment based on customer retention, the growth of the internet has pushed the most dynamic businesses to compete in the electronic market. In literature, there are many studies showing how a company＇s brand affects customer loyalty. Less attention has been paid to the relationship between e-commerce website loyalty and e-customer loyalty. This paper can be included in a stream of research that applies the construct of loyalty to e-commerce. Thus, this study aims to analyze, within the electronic market, the elements influencing and determining the trust and loyalty of the e-customers. This research consists of a descriptive study carried out utilizing the survey method. The population in this study includes 421 e-customers of Italian online multi-brand portals. The instrument of data gathering was a web-questionnaire and the data analysis was based on regression. Findings show a positive relationship between three factors （website technological level, e-service quality, and brand） and e-customer trust. Furthermore, the correlation, among the three variables, trust as mediating variable, and e-customer＇s loyalty, has been revealed. Therefore, it can be basically assumed that trust builds e-customer loyalty.

Investigation into the Customer Loyalty and Corporate Image Relationship

While extant of academic literature shows that service quality and customer satisfaction are key to building customer loyalty,given these equitable,“Does corporate image create loyalty”is the question this research probes.A primary research was conducted among the mobile communication subscribers.A total of 550 subscribers of mobile communication services in Mumbai,India were approached.Of this,400 complete and valid responses were collected.Findings suggest that corporate image and the service quality perceived by the customers have a strong relationship with customer loyalty.This implies that both external marketing and interactive marketing dimensions have a direct impact on building customer loyalty.Customer satisfaction was seen to be completely mediating the relationship between service quality and customer loyalty.This research provides a model that can help the managers of service organizations to enhance customer loyalty.Since corporate image positively impacts the customer loyalty along with service quality,it is important for the industry managers to devote equal attention and resources in delivering the promise as well building a good image of the company.Since the service quality impacts the corporate image,an important takeaway for the managers is to ensure that the actual offer matches promises made externally.Most of the previous studies investigating the antecedents of customer loyalty have either focused on the interactive marketing dimension or the external marketing dimension.This study examines the interplay of both the dimension and its impact on customer loyalty.

Land tenure security,place satisfaction and loyalty in the peri-urban area of Ibadan City,Nigeria

Land tenure security is pertinent to achieving the sustainable development agenda in cities where land is needed and useful for development purposes.Sufficient empirical research has been done to prove the importance of tenure security for investment,resilience,conservation,food security,as well as health and well-being,but it has not been clarified if and how land tenure security could adequately influence place loyalty and satisfaction with the residential environment,as it is clear that place loyalty and satisfaction are pertinent to inclusive development.Using the case of Ibadan City,the study examined how different dimensions of tenure security could determine residents’place loyalty and satisfaction.The study employed a survey cross-sectional research design to distribute 514 structured questionnaires to household heads across 4 sampled peri-urban local government areas while 452 were retrieved for analysis.Hierarchical regression analysis model was employed to understand the association between tenure security dimensions and satisfaction(as model I)and loyalty(as model II).For model I,F=8.640,P=0.000,R=0.555,and R^(2)=0.308 were obtained;while for model II,F=9.157,P=0.001,R=0.415,and R^(2)=0.173 were acquired.This thus means that residents’place loyalty and satisfaction can partly be explained by tenure security.In particular,respondents with no eviction experience,recognized property rights,and invulnerable to eviction have higher odds of being satisfied and loyal.Therefore,we recommend protection,improvement,and upgrading of land tenure security as one of the means to promote place loyalty and satisfaction,which is essential to achieving inclusive and sustainable development.

On the Tarmac of Nationhood： Dismantling Caste and Tribal Loyalty in Aravind Adiga＇s The White Tiger and Shadrach Ambanasom＇s Son of the Native Soil

The White Tiger is Aravind Adiga＇s first novel just like Son of the Native Soil which is Shadrach Ambanasom＇s first oeuvre. The two novels address two major social concerns （the caste system and tribal loyalty） that impair national cohesion in India and Cameroon respectively. Briefly speaking, the caste refers to the classification of peoples in India （and other South Asian countries） into in-marrying hereditary social classes of the privileged and the underprivileged while tribal loyalty refers to selfish attachment to a tribe or clan to the detriment of community or national feeling. The two concepts are related in the sense that the word ＂caste＂ derives from the Spanish or Portuguese ＂casta＂ meaning race, lineage, breed or clan. In both cases therefore, the issues of sectionalism, division, discrimination, selfishness, marginalization, and hegemony （amongst others） are at play--issues that impede the notion of nationhood. Read principally from the Marxist perspective of power dynamics and class struggle, the paper argues that Adiga and Ambanasom through skillful manipulation of symbols, time, characters and events, try to imagine the deconstruction of caste and ethnic loyalty in India and Cameroon respectively, which to the two authors, are only historically and socially erected edifices rather than natural order. For the two authors, although global forces may seem to play in favor of a more equitable human society, a necessarily violent revolution might be required to dismantle a blighted body politico-modus operandi that has operated in the people＇s psyche for a long time, as characters and events in the two novels reveal.
