【摘要】：为解决现阶段园林绿化企业目标成本测算过程未充分考虑项目特色、测算结果误差较大、不具备实际指导意义的问题,在园林绿化项目工作分解结构的基础上,结合粗糙集和支持向量机理论构建园林绿化项目目标成本测算模型。模型首先采用粗糙集理论对园林绿化项目工作包的成本影响因素进行约简,并依据约简属性集从实例库中抽取样本数据;然后,通过支持向量机的回归估计测算出园林绿化项目的目标成本;最后,以某园林绿化企业的绿化种植工程为例,演示了模型的具体实现过程,验证了模型的有效性和实用性。
[Abstract]:In order to solve the problem that the target cost calculation process of landscaping enterprises has not fully considered the characteristics of the project, the error of the calculation result is large, and it does not have practical guiding significance, it is based on the decomposition structure of the landscaping project work. Combined with rough set and support vector machine theory, the target cost calculation model of landscaping project is constructed. Firstly, the rough set theory is used to reduce the cost influencing factors of landscaping project work package. According to the reduction attribute set, the sample data is extracted from the instance database. Then, the target cost of the landscaping project is estimated by the regression of support vector machine. Finally, taking the greening planting project of a landscaping enterprise as an example, the concrete realization process of the model is demonstrated, and the validity and practicability of the model are verified.
