甲供非商品化资源（NCRPE）费用高低与NCRPE生产系统规模密切相关，如何通过缩小生产规模，以降低NCRPE费用既是一个理论问题，也是一个实践问题。首先，根据NCRPE生产系统的特点，分析了NCRPE初始配置的相关费用，研究了初始配置相关费用与NCRPE生产规模之间的关联关系。其次，研究并构建了基于生产规模的项目群NCRPE费用现值优化模型，并选用模拟退火粒子群算法进行仿真实验。最后，开展案例分析，结合项目群Z，验证了模型的可行性与有效性。研究结果表明: 构建的NCRPE费用优化模型能够有效地缩小NCRPE生产规模，降低NCRPE生产系统总费用（建设费用和运行费用之和），从而实现业主支付费用现值最小化。

The cost of non commercial resources by employer(NCRPE) is closely related to the scale of NCRPE production system. How to reduce NCRPE cost by reducing production scale is not only a theoretical problem, but also a practical problem. Firstly, according to the characteristics of NCRPE production system, the related costs of NCRPE initial configuration are analyzed, and the relationship between related costs and NCRPE production scale is studied. Secondly, the present value optimization model of NCRPE cost of the program based on the production scale is studied and constructed, and the particle swarm optimization algorithm is selected for simulation. Finally,a case study is carried out to verify the feasibility and effectiveness of the model combined with program Z. The results show that the NCRPE cost optimization model constructed in this paper effectively reduces the production scale of NCRPE, reduces the total cost of NCRPE production system (the sum of construction cost and operation cost), and minimizes the present value of the cost paid by the employer.
