Such effects would be paid off in the right way only when management of the firms perform marketing activities focusing on long term effectiveness, which would drive company profits up and keep them for long. Demands of customers are being changed and varied. In this result with the advantage of mass marketing and database marketing have been drawing attentions from company. To fulfill these demands of customer, they need a concept of eCRM(Web based Customer Relationship Management), and go from selling products and services, or gathering customer requests, up to the phase of solving customer's problem by real time or previous action. With the help of internet, the frequency and speed of the problem solving has improved greatly. For these purposes, we try to determine the most important and most urgent factors in eCRM: utilization by using SN Ratio Decision making, one of the Multi-criteria decision-making methods SN Ratio Decision making is widely used for determining relative magnitude per evaluation item, i. e. priority on problems and is expected to make more systematic and objective evaluations than conventional methods do. Even in the present situation where any general criterion on eCRM dose not exist, utilization of eCRM is expected to be actively continued, which will cause many problems. In this regard, evaluating eCRM counts.

The concept known as Vehicle-to-Grid (V2G) is to provide power to help balance loads by charging at night when demand is low and sending power to the grid when demand is high. Therefore, it is important to model the cost-benefit characteristics of Electric vehicle(EV)'s operation considering the negawatt market in real time. This paper proposes a methodology to formulate the various costs and economic benefits for sending the EV's power back to the grid, including a concept of inconvenience costs caused by operating the EV as a battery. This paper also introduces the general decision-making process based on the cost-benefit analysis in order to simulate the reasonable participation of V2G service. In the case study, it is confirmed by two-case simulations that the proposed approach is useful to help EV owners' decision-making. In the future, it is expected that the proposed methodology can be used as a decision-making guideline to help prepare the EV' power transmission.

Decision makers in the service industry must effectively cope with queuing problems, service capacity optimization, service efficiency and service quality problems. This study proposes a computer simulation-enabled MCDM framework that integrates computer simulation analysis, Taguchi method, expert opinion and multiple criteria decision making (MCDM) to assist decision makers in coping with decision problems. In this framework, Taguchi method is adopted to reduce the time required for the simulation experiment. Computer simulation analysis is adopted to obtain useful information for rapid decision-making without interrupting actual production. MCDM is used to select the optimal alternative. The illustrative result is extremely promising.

This study explores incomplete decision-making dynamics on reward-based crowdfunding platforms, focusing on temporal and social factors influencing backers' decisions. Utilizing the temporal aspect (i.e., pledging campaign phase) and social aspect (i.e., current pledged amount ratio) as stimuli within the stimulus-organism-response framework, our findings reveal that nearly 50.9% of respondents change their initial decisions, highlighting widespread incomplete information processing. Backers are more prone to altering decisions under heightened time pressure and display herding behaviors. Furthermore, backers exhibit an increased likelihood of changing decisions under heightened time pressure, coupled with a greater chance that the pledged goal amount will not be achieved. The study discusses theoretical and practical implications.

배경 음악은 소비자에게 전달하고자 하는 목표 메시지와 동시에 제시된다. 이 과정에서 필요한 주요 정보를 일정 시간 유지해야 하고, 이러한 정보의 유지에는 청각 작업기억이 필요하다. 일반적으로 배경음악은 그 제시 시간의 제약을 받는다. 이때 배경음악의 시간적 압축이 가능하지만 이 시간적 압축이 작업기억과 구매 의사 결정과정에 미치는 영향에 대해 구체적인 내용이 알려져 있지 않다. 본 연구에서는 이 배경음악의 압축 비율의 변화가 청각 작업기억과 구매 의사결정 과정에 미치는 영향을 분석하고자 했다. 대상은 정상 청각 기능이 확인된 이십대 초반 동질 집단 남녀 37명으로 하였다. 이 집단의 구매성향을 다차원 분석으로 분석하여 고관여도와 저관여도 제품을 선정하였다. 자극 제시 조건은 배경 음악이 없는 조건, 무압축 조건, 저압축 조건, 고압축 조건 으로 구분하였다. 구매에 필요한 청각정보를 전산 합성하여 배경음악과 관련된 4가지 조건에서 무작위로 제시했다. 이 반응 결과를 반복측정분산으로 분석하여 유의수준 0.05에서 판단했다. 결과에서 여러 배경음악 조건에서 청각 작업기억의 가용 총량은 변화가 없었지만, 고관여도인 경우에 저관여도 제품보다 청각 작업기억 자원을 더 사용한 것이 확인되었다. 그러나 이것이 항상 상응하는 최종 구매의사 변화로 연결되지는 않았다. 이러한 분석은 구매의사 결정과정에서 배경음악의 압축이나 청각 작업기억의 역할을 살펴보는 유용한 접근법으로 응용될 수 있을 것으로 판단된다.

Objectives The purpose of this study is to design a research to find clinical factors involved in the decision-making process for determining the constitutional prescription based on prospective clinical data. Methods We have created a draft of the case report form. Therefore, seven constitutional experts was interviewed for additional items to be important used to determine the constitutional prescription in clinic. Interviews were done from December 2012 to March 2014, experts per person 2-3 times, took time of about 120 minutes per interview. Since then, we developed the final case report form through the expert meeting. At the same time, the developing the electronic case report form (eCRF) and the protocol to collect constitutional treatment cases was also discussed. Results & Conclusions The items of the case report form were subject general, lifestyle, health measurement, record of expert, prescription and evaluation after medication. The part of the clinical symptoms of the record of expert allowed to be recorded in the 5-point scale for the collection of quantitative data as much as possible. Assuming a re-visit of the patient, if necessary, twice the recording were to be possible. At the same time, the eCRF and the protocol to collect constitutional treatment cases were also developed. In this study, it will be able to more objectively standardize the medical decision making process that the experts of constitutional prescription decision. As a result, it will be possible to provide the standardized constitutional medical services.

The purpose of this study is to identify the key decision-making variables that lead fashion company employees to participate in the fashion education programs offered by university lifelong education centers. This study also examined the education satisfaction level and preferred education method and evaluated a university lifelong education program by surveying a fashion company employees who completed a fashion education program. As decision making variables, this study included participation purposes, obstacles, and evaluation criteria. While questionnaires were used to identify the decision making variables, education satisfaction level, and preferred education method, focus group interviews were used to evaluate the university lifelong education program. The findings showed that the respondents enrolled in the program mostly because of personal motivations and considered the workload and time limitation as participating obstacles. They considered educational content as the most important evaluation criteria for participating in the program and were highly satisfied with the program they completed. This study suggests how university lifelong education centers may structure their fashion education programs to better appeal to the employees of fashion companies.

In this paper, robot navigation experiments with a new navigation algorithm are carried out in real environments. The authors already proposed a reactive navigation algorithm for mobile robots using optimal via-point selection method. At each sampling time, a number of via-point candidates is constructed with various candidates of heading angles and velocities. The robot detects surrounding obstacles, and the proposed algorithm utilizes fuzzy multi-attribute decision making in selecting the optimal via-point the robot would proceed at next step. Fuzzy decision making allows the robot to choose the most qualified via-point even when the two navigation goals-obstacle avoidance and target point reaching-conflict each other. The experimental result shows the successful navigation can be achieved with the proposed navigation algorithm for real environments.

Shop floor control systems (SFCS) are used to make real-time planning and scheduling decisions to optimize the efficiency of manufacturing shops. These shops exhibit a non-linear, dynamic evolution caused by 1) the concurrent flows of disparate parts following complex routings, 2) a variety of machines that breakdown at random times, 3) stochastic arrivals of new parts with different priorities, and 4) jobs that have probabilistic processing times and transportation times. Because of their ability to capture that evolution faithfully, simulation models are often used in the aforementioned decisions. In this paper, various types of decision-making problems encountered in a shop floor have been investigated and categorized into process related problems and resource related problems for shop floor simulation.
