Measurement of Project Portfolio Benefits With a GA-BP Neural Network Group
提出一种基于遗传算法和BP神经网络群的模型来测量项目组合收益，同时考虑财务与非财务收益及协同效应，相比传统模型均方误差降低94%和83%，为管理者提供实用工具。
To facilitate the project portfolio benefits (PPB) management and realize the maximization of the benefits, a PPB measurement model based on the genetic algorithm (GA)-BP neural network group (GA-BPNNG) is proposed in current research. Unlike traditional benefits management approaches, the proposed model takes full cooperation and information sharing advantages of group learning to measure PPB more accurately, which considers both the financial and nonfinancial benefits and synergy benefits generated from the interrelationships among project portfolio components. To ascertain the priority of the PPB measurement model, the GA-BPNNG model is compared with BPNN and GA-BPNN, two common models in the literature. The mean square error of the GA-BPNNG model reduced by 94% and 83%, respectively, when compared to the BPNN and GA-BPNN models. The results suggest that the PPB measurement model performs more effectively. Therefore, it could be concluded that the proposed model has a better nonlinear fitting effect for PPB measurement. This article can support managers, decision-makers, and management in realizing strategy by providing a practical and scalable tool for PPB measurement.
