A method of topology synthesis based on graph theory and mechanism combination theory was applied to the configuration design of locomotion systems of lunar exploration rovers(LER).Through topology combination of wheel structural unit,suspension unit,and connecting device unit between suspension and load platform,some new locomotion system configurations were proposed and the metrics and indexes to evaluate the performance of the new locomotion system were analyzed.Performance evaluation and comparison between two LER with locomotion systems of different configurations were analyzed.The analysis results indicate that the new locomotion system configuration has good trafficability performance. 展开更多

Information Technology (IT) consolidates as an essential element to support the business strategies to survive and rapidly adapts to changes in the competitive environment. This paper examines the impact of the use of information systems (IS) and strategic organization knowledge (SOK) on firm performance in 150 Brazilian companies. The study uses partial least squares structural equation modeling (PLS-SEM) and establishes models to express the relationship among the constructs examined. The study identifies that the direct influence of 1S use on performance is moderately significant. However, when mediated by orientation strategy, the total effect of IS use on firm performance is demonstrated to be highly significant. The model explains 54% of the variability of firm performance and confirms IS use as a fundamental resource to support strategic business processes. 展开更多

This paper mainly makes a performance evaluation for the industrial structure adjustment of the industrial enterprises, establishing a set of evaluation index system. It uses the mathematics statistics knowledge and management knowledge to establish a scientific and operable performance evaluation model for the industrial structure adjustment of the industrial enterprises. Based on the model, it can make a performance evaluation for the internal industrial structure adjustment of the industrial enterprises and also it can evaluate the performance of the industrial structure adjustu^ent of different industries. 展开更多

To evaluate the impact of GMP on Chinese pharmaceutical industry in a quantitative system, we referred to theories on policy evaluation and industrial organization, and conducted literature review, key person interview, multi-round Delphi and field investigation. We set up the principles to construct our indicator system, reviewed based on the policy objectives of the new GMP for drugs systematically, and analysed the influence path of the new GMP for pharmaceutical manufacturers. We proposed a three-dimensional "structure-conduct-performance" evaluation indicator system. Our evaluation indicator system is accepted by experts and relevant personnel, indicating the three-dimensional evaluation indicator system is feasible to evaluate the impact of the new GMP in Chinese pharmaceutical industry. 展开更多
