It is crucial to properly evaluate the running state of the product family for the enterprises to determine the direction of product family evolution and establish the management strategies of R&D-production-marketing. In order to effectively evaluate the running state of the complex product family system in dynamic evolution with uncertainty factors, a comprehensive evaluation method of the product family state is proposed based on FAHP and the D-S Theory. Firstly, the issue of running state in the product family evolution process is analyzed from four aspects of engineering design, market demand-economy, production capacity and operations management, and on that basis, the comprehensive evaluation index system of the product family running state is established. Then, the weight coefficient of the index in each level is obtained using FAHP, and the qualitative and quantitative analysis methods are combined to make the evaluation process more objective, the evaluation rating of index in each level is calculated according to the D-S Theory, then the overall rating of the product family running state is acquired synthetically. Finally, the effectiveness of this method is verified by the case study of the running state of the small size wheel loader family.

The Development Trend

Abstract We used system theory to analyze the structure of a regional drought disaster system and separated the drought disaster risk system into three subsystems. These were drought disaster-causing factors, disaster-inducing environments, and disaster-bearing bodies. Analysis of the main factors of these subsystems allowed the establishment of a regional comprehensive drought disaster risk evaluation index system. To simultaneously evaluate the distribution and development trends of the regional comprehensive drought disaster risk, we established a dynamic evaluation model. Based on the ideas of the projection pursuit clustering method and the dynamic comprehensive evaluation method, the model can make use of multi-dimensional space–time drought disaster information. The model was applied to evaluate comprehensive drought disaster risk in the Xuzhou region, China. The evaluation results show that the method was able to illustrate the development trend and distribution of the comprehensive drought disaster risk in the Xuzhou region. The clustering zoning results show that Pizhou City is the area with the highest risk in Xuzhou, while Fengxian has the lowest. The development trend of comprehensive drought disaster risk with time is not significant.
