以往传统的公路造价的估算类比性差,无法完全涉及到影响公路造价的多方面的各种因素,精准度低,存在各种各样的问题,很难获得十分准确的造价估算结果。在对造价的影响因素方面,进行造价的特征分析,在此基础上,提出一种简单、实有、有效的约束预测控制算法,构建了影响在公路造价方面的、各种不同属性的数据,利用造价中的目标函数的线性方面的算法,来保证造价估价的精准性。前言当下,工程造价在工程的进程中作用越来越大,而公路的建设是 In the past, the analogy of traditional highway cost estimation was poor, which could not be completely related to various factors that affect highway construction cost. The accuracy was low and various problems existed, so it was difficult to obtain very accurate cost estimation results. Based on the analysis of the characteristics of the cost, this paper proposes a simple, practical and effective constraint predictive control algorithm, constructs the data of various attributes that affect the highway cost, The cost of the objective function of the linear aspects of the algorithm to ensure the accuracy of cost estimates. Preface Nowadays, the project cost plays an increasingly important role in the process of engineering, and the construction of the highway is
