中文摘要:在分析影响建筑业综合实力因素的基础上,选择了规模效益水平、技术装备水平、效率水平三个方面共12个评判指标,建立了建筑业综合实力评价的投影寻踪分类模型(PPC),并利用基于实数编码的加速遗传算法(RAGA)求解最佳投影方向.根据投影值的大小对地区建筑业综合实力进行评价分析.PPC模型具有稳健性好、投影值准确度高、评价结果较为客观等优点,为建筑业综合实力评价提供了一条新的方法与思路.

Research on Construction Industry's Comprehensive Strength Assessment Based on Projection Pursuit Model
Abstract:In the analysis of factors that influenced construction industry's comprehensive strength, 12 assessment factors on the level of scale and benefit, technical equipment, efficiency were selected, and a construction industry's comprehensive assessment model was presented based on projection pursuit classification technique. The optimal projection direction can be obtained by using real coded accelerating genetic algorithm (RAGA), and the projection value was used to assess the construction industry's comprehensive strength. This approach has advantages of robust, accuracy and objective. It provides a new thinking in assessing the construction industry's comprehensive strength.
