In the case of response data missing, the variable bandwidth and one-step local M-estimates are employed to estimate the unknown function and the unknown parameter in the partial linear models. The estimators of nonparametric components are given by one-step local M-estimation, and the estimators of parametric components are obtained by one-step local M-estimation and average method. Moreover, the...
The construction of ldquodigital distribution networkrdquo needs to connect multitudinous information islands in the entire distribution networks and implement the information integration and resource harmonization of multi-heterogeneous distributed systems. The data sharing and exchanging between correlated systems of distribution in China and the characteristic and advantage of data integration...
In this paper, the definition of digital distribution networks embodies the spirits and final goals of digital distribution networks. Therefore, the designing of support platform satisfying the definition of digital distribution networks is an important subject in the process of developing digital distribution networks, and the definition's contents are analyzed to achieve the function requirements...
To improve knowledge management and service levels, and achieve integration of software used in the whole product development process are research purposes here. Existing problems in current researches of non-semantic and semantic models are analyzed. Product development process itself, i.e. origin of semantic information of product, is studied wholly as the research object. Through research on design...
