The statistic of global laptop shipment showed that 161.6 million laptops were sold, 65.23% more than desktop-PCs, and almost the same quantity as tablets in 2017. So, laptop demand is quite high and needs to be researched on what kind of criteria (properties) are crucial. Since there are more than one criteria, this study focuses on multi-criteria decision-making (MCDM) methods in selecting laptops. This study aims to determine the interaction between criteria, and the criteria priorities in laptop selection problem that can be added/changing new features every day and to present the findings/results to the researcher/decision-makers. DEMATEL method is used for determining the interactions which are not observed in laptop literature, and fuzzy AHP is for criteria priorities. The price and brand image of a laptop have more interrelated action than the other main criteria. According to results, the brand image is determined as the most important criteria. Along with the brand image, other/peripheral properties and price criteria have totally two-thirds priority among six main criteria. The brand image along with the price had a dominant effect on other criteria according to the interaction matrices/diagrams. This study also shows that criteria priority results should be considered along with interaction matrices/diagrams that may produce such following information: speed, storage, monitor and other/peripheral properties criteria have overall effecting feature but not strongly, while brand image is a transition criterion along with having the highest priority, and the price criterion is obviously being affected by all criteria.

确定笔记本电脑选择问题中的标准与标准优先级之间的相互作用

全球笔记本电脑出货量的统计数据显示,2017年笔记本电脑的销量为1.616亿笔记本电脑,比台式电脑多65.23%,与平板电脑的数量几乎相同。因此,笔记本电脑的需求非常高,需要根据哪种标准进行研究(属性)至关重要。由于存在多个标准,因此本研究着重于选择笔记本电脑的多标准决策(MCDM)方法。这项研究旨在确定标准之间的相互作用以及笔记本电脑选择问题中可以每天添加/更改新功能的标准优先级,并将发现/结果呈现给研究人员/决策者。DEMATEL方法用于确定笔记本电脑文献中未观察到的相互作用,而模糊AHP用于确定标准优先级。笔记本电脑的价格和品牌形象比其他主要标准更具关联性。根据结果​​,品牌形象被确定为最重要的标准。除品牌形象外,其他/周边属性和价格标准在六个主要标准中总共占三分之二。根据交互矩阵/图表,品牌形象和价格对其他标准具有显着影响。这项研究还表明,应优先考虑标准优先级结果以及可能产生以下信息的交互矩阵/图表:速度,存储,监控和其他/外围属性标准具有整体影响力,但没有强烈影响,而品牌形象是过渡标准以及最高优先级
