In addition to the traditional financial perspective goals, the scorecard suggests a holistic, flexible, powerful and balanced approach to measuring and managing corporate performance. Measures from the perspectives of customer, process and learning are identified as drivers for financial performance. The process of developing the balanced scorecard clarifies and communicate corporate strategy to every employee in the organization. The goals of respective business units and individuals can thus be aligned to improve overall quality service.展开更多

Previous configuration approaches, such as static resource reservation, dynamic resource allocation and single service composition are not valid in the environments. In this study, we present an adaptive service configuration approach. Firstly, we reduce the dynamic configuration process to a control model which aims to achieve the variation of critical QoS on minimal level with less resource cost. Secondly, to deal with different QoS variations, we design two configuration strategies—service chain reconfiguration and QoS parameter adjustment—and implement them based on fuzzy logic control theory. Finally, a configuration algorithm is developed to flexibly employ the two configuration strategies in tune with the error of critical QoS in configuration process. The results of simulation experiments suggest that our approach outper- forms existing configuration approaches in both QoS improvement and resource utilization.展开更多

Compared with delay compensation-AQM algorithm(DC-AQM),proportional-integral-derivative(PID) algorithm and random exponential marking(REM) algorithm,the RBM scheme exhibits the superiority in terms of stability, responsiveness and robustness.展开更多

In this study, a descriptive cross-sectional survey was adopted as the study design. The sample size included 180 vips residing in tourist hotels in Arusha at the time of data collection, 240 service employees, and 28 managers. Purposive, convenient, and simple random sampling methods were used in sampling. A structured questionnaire was used as an instrument of data collection. Data were analyzed by means of Statistical Package for Social Sciences （SPSS） computer package （Version 16） and expressed in descriptive and inferential statistics. The analysis of variance （ANOVA） was used to measure the gap between the managers＇ and vips＇ perceptions, while independent t-test analyzed the role played by managers＇ practices in delivery of quality service. The findings show that in general hotel product, two attributes were found to be significant at the level ofp 〈 0.05. In the front office, restaurant and bar, and viproom, the results showed that three, six, and nine attributes were respectively found to be significant at the level of p ≤ 0.05. The analysis of management practices provided the evidence that eight practices were significant at the level of p ≤ 0.05. From the findings, two conclusions were made. First, managers＇ and vips＇ perceptions on service quality standards differ significantly; second, it was found that management practices influence significantly the service quality standards in tourist hotels in Arusha.展开更多

文摘Active queue management(AQM) is essentially a router buffer management strategy supporting TCP congestion control.Since existing AQM schemes exhibit poor performance and even instability in time delay uncertain networks,a robust buffer management(RBM) mechanism is proposed to guarantee the quality of service(QoS).RBM consists of a Smith predictor and two independent controllers.The Smith predictor is used to compensate for the round trip time(RTT) delay and to restrain its negative influence on network performance.The main feedback controller and the disturbance rejection controller are designed as proportional-integral (PI) controller and proportional(P) controller by internal model control(IMC) and frequency-domain analysis respectively.By simulation experiments in Netwrok-Simulator-2(NS2),it is demonstrated that RBM can effectively manage the buffer occupation around the target value against time delay and system disturbance. Compared with delay compensation-AQM algorithm(DC-AQM),proportional-integral-derivative(PID) algorithm and random exponential marking(REM) algorithm,the RBM scheme exhibits the superiority in terms of stability, responsiveness and robustness.

The human resources processes leading to external service quality are consolidated into a quality management framework. With reference to the framework, the factors, their importance and relationships within each process are established by the responses of practicing salespersons. A clear picture of the underlying management mechanisms leading to strong sales forces and service quality are produced. Retail management is required to better establish and manage the human resource.

文摘To build an“ecological and livable city”,it is important to figure out the relationship between human activity and urban park space and create a high-quality urban park through the integration of“people”and“park”.Taking Longhu Park in Huainan Province as an example,the study quantitatively analyzed and evaluated the characteristics and service quality of slow traffic space using importance-performance analysis(IPA)and space syntax,clarified the key indexes and areas to be optimized,and put forward corresponding design countermeasures and suggestions in combination with human activity demand.The results suggest that:①The mean performance of park recreation service quality is 3.63,less than the mean importance(3.95).Tourists pay special attention to the safety and convenience of slow traffic space,and the diversity and identiability of site functions is the focus“to be improved”.②The accessibility of Longhu Park shows a strong irregular shape in the southwest.The dead-end roads in the far lake area and the flora and fauna area on the northwest side have weak spatial perception,and the composite function carrying potential of slow traffic space is better reflected in a small range.Therefore,an optimization strategy for slow traffic space is proposed to enhance the continuity of road network,site identifiability,and functional diversification.The results will provide new thoughts of governance based on spatial humanism for the high-quality renewal of urban parks in the new era.
文摘The gap in knowledge that existed between the level of service quality standard and the potential of the tourism industry in Tanzania justified the need for the researchers to conduct this study. In this study, a descriptive cross-sectional survey was adopted as the study design. The sample size included 180 vips residing in tourist hotels in Arusha at the time of data collection, 240 service employees, and 28 managers. Purposive, convenient, and simple random sampling methods were used in sampling. A structured questionnaire was used as an instrument of data collection. Data were analyzed by means of Statistical Package for Social Sciences （SPSS） computer package （Version 16） and expressed in descriptive and inferential statistics. The analysis of variance （ANOVA） was used to measure the gap between the managers＇ and vips＇ perceptions, while independent t-test analyzed the role played by managers＇ practices in delivery of quality service. The findings show that in general hotel product, two attributes were found to be significant at the level ofp 〈 0.05. In the front office, restaurant and bar, and viproom, the results showed that three, six, and nine attributes were respectively found to be significant at the level of p ≤ 0.05. The analysis of management practices provided the evidence that eight practices were significant at the level of p ≤ 0.05. From the findings, two conclusions were made. First, managers＇ and vips＇ perceptions on service quality standards differ significantly; second, it was found that management practices influence significantly the service quality standards in tourist hotels in Arusha.
