Aiming at the problem of high precision trajectory prediction in air traffic control automation system, a new method based on improved sliding window polynomial fitting prediction is proposed. This method improves the traditional sliding window polynomial fitting method and selects an appropriate historical data group for every predicted value, which provides every prediction with a suitable polynomial...
Unmanned aerial vehicle (UAV) path planning under complex environment, especially under the threat of moving targets is a research difficulty in the field in those years. Aiming at above problem, a method based on MGM (1, n) model for predicting threat of moving targets three-dimensional coordinate of real-time path planning is putted forward. The method is to build three-dimensional search space...
Aiming at the problem of trajectory prediction in air traffic control automation system, a new method of trajectory prediction based on aircraft motion model and grey theory is proposed. This method combines the aircraft motion model and the prediction method of grey theory, which realizes the real-time online trajectory prediction and improves the prediction accuracy. This prediction method has strong...
The essence of design innovation was the innovation of knowledge. Favorable knowledge accumulation and update mechanism were an important foundation to realize product innovation. Knowledge acquisition and innovation mode oriented to problem were offered aim at the bottleneck problem of the product concept innovation stages. Knowledge acquisition from generalized experts and innovation process which...
Aiming at the bottleneck problem of the product concept innovation stages, and on the basis of new interpretation to the essence of product innovation, the concept of generalized experts oriented to product innovation was put forward guided by the comprehensive integration methodology. Mechanism of generalized experts' motivation was proposed on the basis of related motivational psychology. Thinking...
This study examines the relationship between supplier control and firm performance and the role of knowledge sharing intention and cooperation risk. Using data collected from China Mobile, we demonstrate that formal control and social control are both positively related to supplier's knowledge sharing intention, but negatively related to cooperation risk. We also find that supplier's knowledge sharing...
this paper empirically explores value co-creation capability including product supply capability and service integrated capability, and its impact on cooperation performance, with trust as mediator. With the data from China national petroleum Group, China mobile Group and China Telecom Group, the framework is tested. The results show that product supply capability is positively related to cooperation...
To solve multi-criteria decision making problem in selecting an extended enterprise of rapid extended manufacturing, the index system of comprehensive evaluation for extended enterprise was built. A new method was proposed using analytical hierarchy process and fuzzy comprehensive evaluation. The whole process of the method was introduced step by step. Firstly, the fuzzy judgment matrix was established...
Manufacturing execution system platform is proposed combine the idea of software reusing with the characteristics of the field of aerospace enterprise. The system structure of manufacturing execution system platform is introduced and features of MES platform are expounded. Application system development process based on MES platform is described in detail. According to its production features, enterprises...
In order to build extended logic manufacturing cell (ELMC) supporting rapid extended manufacturing (REM), the technology for ELMC based on similarity theory and clustering analysis was proposed. The question of ELMC was expounded, and computation of process similarity factor was introduced. The construction algorithm of ELMC was detailed discussed. Firstly, similarity matrix of processing task was...
Due to the fact that crucial and often the complex components of product can not be manufactured outsourcing as a whole in one organization, this paper presents a solution of manufacturing execution supporting rapid extended manufacturing. The background of rapid extended manufacturing and Manufacturing Execution System are explained. The article analyzes several main issues of manufacturing execution...
ERP(Enterprise Resource Planning) system are implemented as a total business solution that gain significant advantages, including dramatic increases in productivity, on-time shipments and sales, as well as decreases in lead times, purchase costs, quality problems, and inventories. But many ERP system implementations are not success stories. Many failed REP system implementations may be attributed...
This paper empirically explores strategic interactions between service integrator and customer, and the role of product service and integrated service on interpartner legitimacy based on capability approach and institutional legitimacy theories. The result shows that strategic interactions between service integrator and customers have significant influence on interpartner legitimacy in service supply...
In this paper, based on literature and theory review, we advanced the framework of the service integrator ability and argued that resources and supply capability, demand management and strategy fit with customer are three critical factors to service integrator's competitiveness. We further hold empirical study based on these hypotheses, the result shows that the factors have different impact on competitiveness...
