| Summary: | 碩士 === 淡江大學 === 資訊管理學系碩士在職專班 === 104 === Retail services thrived up during the last decade. Ecommerce threatens the traditional retailers and creates a more dynamic environment. In addition, the changes of consumer behavior forced the industry to alter the original competition patterns. To attain competitive advantages, retailers are forced to implement information technology and develop virtual communities. For instance, O2O, shopping recommended, location based service, customer service experience, automatic payment, electronic payments, and mobile POS has become critical issues and challenged the capabilities of information system. Consequently, retailers demand an efficient POS system to response the rapid changes of microenvironment and provide better services to the customers. Since different Point of Sale (POS) systems have various features and services, decision makers are hard to conduct a rational assessment within the limited time. Consequently, the decision-making will be bias and constrained by the personal judgments or budget limits. This paper will use ERVD (election based on relative value distances) to develop an evaluation tool for POS system in retail industry, and therefore provide a better solution to the decision makers.
