用户偏好变化分析是改善用户策略、提升个性化服务的重要指标。为满足用户需求,需要对用户偏好以及未来用户行为的发展作深入分析。基于此,文章提出分析图书馆用户偏好变化的多指标决策方法,构建影响用户偏好的满意度指标聚类集合,并确定各评价指标的权重。基于多指标决策框架和方法的分析结果,主要集中在评估用户偏好的潜在发展趋势,并帮助图书馆决策者追踪用户偏好的改变,以及根据这些偏好改进信息服务。 相似文献

根据当前公众满意度测评的特点,本文引入基于期望值的模糊多属性决策方法进行政府门户网站的满意度测评研究.考虑到政府门户网站开展满意度评价的实际情况,文中采用三角模糊数方法得到带有定量指标和定性指标的区间型评价矩阵.并就指标权重完全未知和部分未知两种情况,运用基于期望值的模糊多属性决策原理,结合主观偏好值和客观偏好值求解得到指标权重.最后的实证研究说明该方法可行、有效. 相似文献

供应商选择问题一直是业界十分关注的决策问题.本文在分析已有的多准则问题决策方法局限性的基础上,建立了基于AHP、熵值法与TOPSIS相结合的多层次选择评价模型.AHP是一种常用的确定指标权重的方法,不足之处在于当供应商在某一指标上的得分趋于相同导致该指标的鉴别能力降低时,AHP确定的指标权重无法及时反映这一变化,为此用熵值法进行了改进,从而提高指标的鉴别能力.最后使用TOPSIS方法对候选供应商进行最终评价,并结合算例证明了该方法的有效性. 相似文献

改进密切值法及其在图书供应商选择中的应用 总被引：1，自引：1，他引：0
如何选择信誉好、服务优的图书供应商已经成为图书馆图书采购必须要解决的首要问题。本文将改进密切值法应用于图书供应商选择的综合评价研究。图书供应商的优劣选择主要取决于供应商的图书供应能力、服务质量、价格、信誉、交货期等因素,涉及书目供全率、书目重复比率、按期交货率、到书率等多个评价指标。首先由各图书供应商选择的各个评价指标的极端情况组成“虚拟”的最好和最差供应商方案,其次求出各个图书供应商与最好、最差供应商方案的距离,再引进可综合反映与最好和最差供应商方案距离两者水平的综合参数—密切值。计算实例表明,用改进密切值法的排序结果可靠,用于图书供应商的综合选择评价与排序是切实可行的,并且密切值法计算过程简单,很容易实现计算机化。 相似文献

Digital library (DL) evaluation is essential to the success and enhancement of DLs. However, there is a lack of research on the assessment of comprehensive evaluation criteria across multiple dimensions of DLs. In particular, limited research is available on criteria prioritization to determine which criteria are perceived important by different stakeholders. This study was conducted to compare similarities and differences in perceptions of the importance of different DL evaluation criteria by heterogeneous stakeholders in academic settings. Ninety subjects were recruited with 30 from each of the group representing DL scholars, DL librarians, and DL users. Subjects were instructed to fill in an in-depth survey consisting of 10 evaluation dimensions with 94 criteria. ANOVA and t-test were applied to examine the similarities and differences among the three groups. This study reveals consensus and divergence in perceptions of criteria importance among the three groups, and indicates an inherent tension among the stakeholders. Moreover, the differences identify gaps not only between user expectations and the DL practice but also between what's desirable and what's possible in the academic environment. The findings provide a comprehensive list of criteria to guide practical evaluation of DLs, and contribute to the narrowing of the identified gaps. 相似文献

The history of user evaluation of reference service is traced and related to other methods of reference evaluation, including librarian self-report of success, behavioral guidelines, and unobtrusive observation. Presently available user-report instruments are considered in light of criteria for a reference evaluation instrument. It is concluded that reference success can't be explained by any one group of factors, and that the best evaluation will utilize multiple methods. 相似文献

A new formulation of the reverse bin-packing problem is suggested. One distinct feature of the new formulation is that it takes into account of a decision-maker’s preferences for a set of objects that are evaluated by multiple quality criteria. The aspects of this problem are discussed that relate to the theory of multiple criteria decision making. The known methods for solving the classic and the reverse bin-packing problems (the multiple knapsack problem) are reviewed. 相似文献

The aim of this study is to find the critical factors that influence Taiwan's national museum business performance based on its curators’ views. The study explored the causal relationships among the criteria that emerged in the study and of each sub‐criteria. Since developing a business strategy is a multiple‐criteria decision‐making (MCDM) problem, this study adopted the causal‐effect model of decision‐making trial and evaluation laboratory (DEMATEL) technique. The DEMATEL technique simplifies and visualizes the interrelationships among decision‐making criteria. The study identified four core criteria – benefits, opportunity, costs, and risks, as key influencers in the national museum business performance. Each key criteria was supported by a set of sub‐criteria which, when considered together, produced an influential network relations map. The results of this study provided Taiwan's national museum curators with an idea‐based understanding of how to create business and marketing strategies that could enhance exhibition features, experience activities, and facilities that could be linked to satisfaction of visitors’ desires and offer a potentials strategy for assessing likelihood of return visits. 相似文献

Over the last three decades, research in Information Retrieval (IR) shows performance improvement when many sources of evidence
are combined to produce a ranking of documents. Most current approaches assess document relevance by computing a single score
which aggregates values of some attributes or criteria. They use analytic aggregation operators which either lead to a loss
of valuable information, e.g., the min or lexicographic operators, or allow very bad scores on some criteria to be compensated
with good ones, e.g., the weighted sum operator. Moreover, all these approaches do not handle imprecision of criterion scores.
In this paper, we propose a multiple criteria framework using a new aggregation mechanism based on decision rules identifying
positive and negative reasons for judging whether a document should get a better ranking than another. The resulting procedure
also handles imprecision in criteria design. Experimental results are reported showing that the suggested method performs
better than standard aggregation operators. 相似文献

Objectives: To develop a patient information leaflet (PIL) to help local patients meet their drug information needs using the Internet, and to perform a preliminary evaluation of this tool. Methods: Development—a cross‐sectional survey of the drug information needs of local patients using a semi‐structured questionnaire; assessment of websites offering free, consumer‐orientated medicines information using set criteria; identification of consensus criteria to evaluate the quality of health‐related on‐line information; evaluation—views on a draft patient information leaflet from a focus group. Results: Those surveyed felt that being directed to high‐quality websites and being provided with assessment criteria for on‐line information would be useful. The three websites fulfilling most of the set quality criteria were Surgery Door ( www.surgerydoor.co.uk ), InteliHealth ( www.intelihealth.com ) and medline plus ( www.nlm.nih.gov/medlineplus ). The six most frequently cited assessment criteria were currency, authorship, commerciality, relevance, links and attribution. A draft leaflet was constructed listing the above three websites and six criteria along with tips on how to search the Internet effectively. A focus group reacted favourably. Conclusion: The Internet is a source of drug information—an information leaflet may help to guide local patients through its variable information quality. 相似文献

The Core List of Journals for Libraries that Serve Schools and Colleges of Pharmacy is a guide for developing and maintaining pharmacy-affiliated library collections. A work group was created to update the list and design a process for updating that will streamline future revisions. Work group members searched the National Library of Medicine catalog for an initial list of journals and then applied inclusion criteria to narrow the list. The work group finalized the fifth edition of the list with 225 diverse publications and produced a sustainable set of criteria for journal inclusion, providing a structured, objective process for future updates. 相似文献

The essay presents criteria for a “good theory” and then reviews advances in small group communication research during the 1980s. The fact that comparatively few scholars are dedicated to such research is then related to the criteria for good theory in discussions of, first, metaphors and imagination; second, puzzles and problems; and third, real‐world significance and outcomes. A call is made for the kind of research that will result in better small group theory. 相似文献
