Abstract: To improve management and control capacities of manufactory for service value chain,a collaboration capability evaluation index system was designed for service stations who had constructed collaboration relationship with manufactory.Based on the evaluation index system,a nested ensemble classifier was proposed for evaluation of collaboration capability of service station with manufactory.Based on service business dataset,initial evaluation solutions were calculated by subjective combination weights and objective combination weights.Using the initial evaluation solutions and ridge regression method,the nested ensemble classifier was constructed and used to calculate the final evaluation solutions.Experiments showed that the nested ensemble classifier had a promising result compared with other ensemble algorithms.Especially based on real service business data,experimental results illustrated that the performance of nested ensemble classifier was more prominent than others.
