二、思维导图（Mind mapping）

三、精读内容（Intensive reading content）

（一）德尔菲法简介（Introduction to the Delphi Method）

德尔菲法是一种专家调查方法，采用函件方式将研究问题发送给事先选定的专家征询意见，整个过程避免专家之间的直接讨论和横向联系。研究步骤包括：收集并整理专家意见，对新增建议进行补充、对否定内容进行删除，然后将整理后的结果再次发给专家征询。通常经过2至3轮的意见征询与反馈，最终能够达成相对一致的结论。

The Delphi method is an expert survey method that uses a letter format to solicit research questions from pre-selected experts, avoiding direct discussion or cross-disciplinary communication between experts. The research process involves collecting and organizing expert opinions, supplementing new suggestions, and deleting negative ones. The results are then sent back to the experts for further consultation. Typically, after two to three rounds of consultation and feedback, a relatively consistent conclusion is reached.

（二）专家咨询表（专家调查问卷）编制（Preparation of expert consultation form (expert questionnaire)）

该过程以表3.4中的评价指标为基础，设计专家问卷，调查内容包括专家对各指标的重要性、判断依据及熟悉程度（见表3.5）。第一轮调查收集并分析专家意见，允许专家提出新指标并说明含义，或对现有指标提出异议并给予量化评价。若第一轮未达成一致意见，则需进行第二轮甚至更多轮调查，直至形成统一结论。

This process uses the evaluation indicators in Table 3.4 as a foundation, developing an expert questionnaire that covers experts' opinions on the importance of each indicator, their basis for judgment, and their familiarity with it (see Table 3.5). The first round of surveys collects and analyzes expert opinions, allowing them to propose new indicators and explain their meanings, or to raise objections to existing indicators and provide quantitative evaluations. If consensus is not reached in the first round, a second or even further round of surveys will be conducted until a consensus is reached.

（三）咨询专家选取（Consulting expert selection）

本次德尔菲法专家咨询共选取12名专家，构成涵盖建筑施工企业（8人）、BIM软件供应商（2人）、高校（1人）及政府下属单位（1人）。专家平均年龄约40岁，平均工作年限约20年，均为副高及以上职称，本科学历100%，研究生及以上学历占71.43%，以确保专业知识与经验对评价结果的可靠性。

A total of 12 experts were selected for this Delphi expert consultation, representing eight construction companies, two BIM software vendors, one university, and one government agency. The experts averaged approximately 40 years of age, with an average of 20 years of experience. All held associate senior professional titles or higher, with 100% holding a bachelor's degree and 71.43% holding a master's degree or higher, ensuring the reliability of the evaluation results based on their expertise and experience.

（四）统计结果分析（Statistical results analysis）

1. 统计分析指标（Statistical analysis indicators）

专家意见回收后，对评价指标的重要性、判断依据及熟悉程度进行了统计分析，包括内部一致性信度（Cronbach α系数）与内容效度（S-CVI/Ave系数）、专家积极系数、专家权威系数、意见协调系数、指标均值、满分比、标准差与变异系数。同时进行了指标界值分析，当满分比低于界值或变异系数高于界值时考虑删除对应指标。指标删除的目的是确保专家对各指标的保留或调整意见达成一致。

After collecting expert opinions, we conducted a statistical analysis of the importance, judgment basis, and familiarity of the evaluation indicators. This included internal consistency reliability (Cronbach's α coefficient), content validity (S-CVI/Ave coefficient), expert positivity coefficient, expert authority coefficient, opinion coordination coefficient, indicator mean, full score ratio, standard deviation, and coefficient of variation. We also conducted an indicator cutoff analysis. When the full score ratio fell below the cutoff or the coefficient of variation rose above the cutoff, the corresponding indicator was considered for deletion. The purpose of removing indicators was to ensure expert consensus on whether to retain or adjust each indicator.

2. 第一轮调查结果（First round survey results）

第一轮调查中，专家积极参与率为100%，整体Cronbach α系数为0.93，各维度均高于0.7，S-CVI/Ave为0.92，各维度均高于0.90，信度与效度均较高，专家权威系数均高于0.7。部分专家提出增加软件效率和效益指标。对均值、满分比和变异系数分析显示，“售后问题有效解决”等指标变异系数偏高，需进一步考虑。界值分析提示可能删除的指标包括业务流程合理、监控及评价、售后问题有效解决、一次性解决问题能力、已有规模与用户数量及财务状况。专家意见协调系数为0.37，经卡方检验（P>0.05）尚未一致，需要第二轮调查。

In the first round of the survey, the expert participation rate was 100%, with an overall Cronbach's α coefficient of 0.93, and all dimensions exceeding 0.7. The S-CVI/Ave coefficient was 0.92, with all dimensions exceeding 0.90. Reliability and validity were high, and the expert authority coefficient was above 0.7. Some experts suggested adding software efficiency and effectiveness indicators. Analysis of means, full score ratios, and coefficients of variation revealed that the coefficients of variation for indicators such as "effective resolution of after-sales issues" were high, requiring further consideration. A threshold analysis suggested that indicators that may be removed include reasonable business processes, monitoring and evaluation, effective resolution of after-sales issues, ability to resolve issues in one go, existing scale and number of users, and financial status. The expert consensus coefficient was 0.37, and chi-square tests (P>0.05) showed no consensus, necessitating a second round of surveys.

3. 第二轮调查结果（Second round of survey results）

第二轮调查在第一轮基础上增加软件效率指标。结果显示专家意见协调系数升至0.45，卡方检验（P

The second round of surveys added software efficiency indicators to the first round. The results showed that the expert consensus coefficient rose to 0.45, and the chi-square test (P

四、知识补充（Knowledge supplement）

在德尔菲法实施过程中，对专家意见进行科学统计分析是确保研究结果可靠性的重要环节。首先，内部一致性信度（Cronbach α系数）用于评估问卷中各评价指标间的一致性，数值越高表明指标间反映同一概念的可靠性越强。其次，内容效度（S-CVI/Ave系数）衡量评价指标覆盖研究主题的完整性和科学性，反映专家对指标体系的认可程度。专家积极系数表示专家对问卷的参与程度，直接影响意见的代表性与可靠性，而专家权威系数则通过专家的判断依据和熟悉程度量化其专业性，权威系数越高，专家意见越值得信赖。

During the Delphi method, scientific statistical analysis of expert opinions is crucial for ensuring the reliability of research results. First, internal consistency reliability (Cronbach's α coefficient) assesses the consistency between the various evaluation indicators in the questionnaire. A higher value indicates a greater degree of reliability in reflecting the same concept. Second, content validity (S-CVI/Ave coefficient) measures the completeness and scientific nature of the evaluation indicators in covering the research topic, reflecting the experts' acceptance of the indicator system. The expert engagement coefficient indicates the level of expert participation in the questionnaire, directly influencing the representativeness and reliability of the opinions. The expert authority coefficient quantifies the expert's expertise based on their judgment and familiarity with the questionnaire. A higher authority coefficient indicates a more trustworthy expert opinion.

专家意见协调系数用于衡量各专家在评价指标上的意见一致性，系数越高说明专家间意见趋于统一，有助于判断是否需要进一步轮次的调查。对于具体评价指标，还需计算均值、满分比、标准差和变异系数，其中均值反映指标的重要性程度，满分比显示专家给予最高评价的比例，而标准差和变异系数则揭示指标评价的离散程度。

The expert opinion coordination coefficient measures the consistency of expert opinions on evaluation indicators. A higher coefficient indicates closer consensus among experts, which helps determine whether further rounds of investigation are necessary. For specific evaluation indicators, the mean, percentage of full scores, standard deviation, and coefficient of variation are also calculated. The mean reflects the indicator's importance, the percentage of full scores indicates the proportion of experts who gave the highest evaluation, and the standard deviation and coefficient of variation reveal the degree of dispersion in the indicator evaluation.

结合均值和变异系数，可通过指标界值分析判断某些指标是否需要删除或调整，从而确保最终指标体系既科学合理，又能反映专家共识。这些统计指标在德尔菲法中相辅相成，共同保证了专家意见收集、整理和筛选的科学性与规范性。

Combining the mean and coefficient of variation, indicator threshold analysis can be used to determine whether certain indicators need to be deleted or adjusted, ensuring that the final indicator system is both scientific and reasonable and reflects expert consensus. These statistical indicators complement each other in the Delphi method, jointly ensuring the scientific and standardized collection, compilation, and screening of expert opinions.
