碩士 === 臺中健康暨管理學院 === 資訊工程學系碩士班 === 93 === Efficiency of picture archiving communication systems (PACS) has already been discussed extensively on a lot of academic papers. The medical institutes in Taiwan state that they will invest money in developing PACS within five years. However, the amount of money needed for the investment is quite huge, so setting up a model of evaluation allows the way to complement with the decision of construction planning, and therefore successfully constructing PACS. Referring to a lot of basic ideas of PACS from articles, the equipments and the situation of each hospital are different, and, therefore, the structure of the PACS will be different as well. According to the references in this thesis and the plan of a regional hospital on the aspect in the whole construction by six manufacturers, the factors needed to be considered to PACS construction include 8 major aspects and 28 items of criterion. Each factor was given different weighting based on the statistics of questionnaire investigation. Finally, the evaluation was made by the PACS committee of the regional hospital and was graded in accordance with the content of the grade form. The decision was made according to the grey relation analysis (GRA), in order to determine the priority of each PACS manufacturer for constructing PACS. In the past, only cost and performance were paid attention for PACS construction. This research thesis considered with different respects in decision theories, and provided another mode of decision making with consideration of whole quality.
