加权评分模型为基于各种标准选择一个合适的项目提供了一种系统化的方法

• Identify criteria important to the project selection process 为每个待选项目确定重要的评价标准
• Assign weights (percentages) to each criterion so they add up to 100% 分配每个标准的权重占比，使它们相加等于100%
• Assign scores to each criterion for each project 针对每个项目对应每个评价标准打分
• Multiply the scores by the weights and get the total weighted scores 将分数和所占权重相乘，得到总的加权分数
