Call centers do not simply play a role of responding to customers' calls, but they have developed into a core unit for maintaining competitiveness through services, marketing, or sales. Since the service quality of call centers heavily affects customer satisfaction, organizations have focused on enhancing it by reducing waiting time and increasing service level. One of the techniques, which improve the service quality of call centers, is to employ multi-skilled agents that can handle more than one type of calls. This study deals with three issues relevant to multi-skilled agents. First, we analyze how the way of allocating a specific group of agents to a set of skills affects the performance of call centers. Secondly, we investigate the relationship between the number of multi-skilled agents and the performance of call centers. Finally, we examine the impact of agent selection rules on the performance of call centers. Two selection rules are compared : the first rule is to assign a call to any available agent at random while the other rule is to assign a call preferably to single-skilled agents over multi-skilled agents when applicable. Based on simulation experiments, we suggest three implications. First, as the length of cycles in the agent-skill configuration network becomes longer, call centers achieve higher service level and shorter waiting time. Secondly, simulation results show that as the portion of multi-skilled agents increases, the performance of call centers improves. However, most of the improvement is attained when the portion of multi-skilled agents is relatively low. Finally, the agent selection rules do not significantly affect the call centers' performance, but the rule of preferring single-skilled agents tends to distribute the workload among agents more equally.

The purpose of this research is to find out the service quality dimensions and detailed elements of a call center, and to study what relationship the service quality dimensions have with service recovery and customer royalty. This research set up the hypothesis and the research model to verify the relationship between the call center service quality and the service quality customer royalty for 139 people surveyed who experienced dissatisfactions. The result of the hypothesis verification shows that it has an influence on the counselors' service quality and service recovery processes of 3 call centers. The service recovery has en influence on the customer royalty. The result quality as a result remained for a customer after counseling can be called the ultimate purpose of using the call center for a customer, and the research shows that it has the largest influence on the service recovery of 3 dimensions of the call center service quality. In the relationship between the service recovery and the customer royalty, the service recovery has a meaningful influence on the customer royalty.

The purpose of this paper is to test whether prices of mobile communication service reflect their varying degrees of call quality, controlling for other service attributes. As, in fact, service is intangible goods difficult to measure its value, this paper makes use of econometric model, hedonic price analysis. Hedonic price analysis, has ever been applied in public or environmental economics, is employed and produces estimates of the prices (or the contributions toward the total price) for each characteristic. This paper applied hedonic technique to the value measurement of a service property for the use of Korean mobile communication. This paper uses actual transaction prices of mobile communication service to determine whether or not the market functions in pricing call quality of mobile communication service. Finally, this show that the willingness to pay of consumer increases as call quality increases and so market makes prices on call qualities. Thus, major concern in this paper is about value measurement o service quality, and also suggest of the possibility to determine call quality value (or price) of mobile communication service.

Objectives: The purpose of this study is to figure out that Facilitation education can affect significant improvement in sales staff's understanding of precise pharmacokinetics, benefits, safety, and side effects, etc. and eventually lead to increase in call after taking courses. Methods: Data utilized in this study was collected from 413 sales staffs who completed Facilitation course for 5 months. This study used statistical methodologies, paired t-test, exploratory factor analysis, and logistic regression model in order to identify change in Call and after Facilitation courses. Results: The result shows that there are statistically significant increases in CALL quality after Facilitation courses based on the result of pared t-test. Moreover, Facilitation education is more effective in average time of one-time detail than average number of visits per day and average number of doctors per day from the result of logistic regression. Conclusions: In order for MR in pharmaceutical company to improve CALL quality, the education for precise pharmacokinetics, benefits, safety, and side effects is necessary. In addition, various professional training required for detail, including disease education, Selling Skills education, and literacy education are essential. Therefore, Facilitation education would be desirable choice in terms of pharmaceutical marketing strategy.

Provisioning of quality of service (QoS) is a key issue in any multi-media system. However, in wireless systems, supporting QoS requirements of different traffic types is a more challenging problem due to the need to simultaneously minimize two performance metrics - the probability of dropping a handover call and the probability of blocking a new call. Since QoS requirements are not as stringent for non-real-time traffic, as opposed to real-time traffic, more calls can be accommodated by releasing some bandwidth from the already admitted non-real-time traffic calls. If the released bandwidth that is used to handle handover calls is larger than the released bandwidth that is used for new calls, then the resulting probability of dropping a handover call is smaller than the probability of blocking a new call. In this paper, we propose an efficient call admission control algorithm that relies on adaptive multi-level bandwidth-allocation scheme for non-realtime calls. The scheme allows reduction of the call dropping probability, along with an increase in the bandwidth utilization. The numerical results show that the proposed scheme is capable of attaining negligible handover call dropping probability without sacrificing bandwidth utilization.

In this paper, we propose a call admission control scheme that can be performed within guaranteeing of required QoS(Quality of Services) in DS-CDMA(Direct Sequence-Code Division Multiple Access) reverse link. It has been performed rely on a physical channel numberonly and based on quality of received signal from MODEM(modulator/demodulator) part in established study. In other methods, the standard for services would have been set from statistical analysis of users\` location and using received power level in BTS(Base Transceiver Station). These ways bring about not only system loads but time delay or great differences from real environment. To solve these problems, we propose a call drop rate estimation algorithm for the purpose of call admission control based on measured value at LNA(Low Noise Amplifier) ports of BTS(Base Transceiver Station) in real time. This method proposed in this paper estimates a quality of offered service in real time, reduce system loads and shorten time delay which is needed to determine the standard for call admission control. But it requires a additional 17W complexity which can measure received signal power in BTS and estimate call drop rate.
