By analyzing the module and concrete items of risks in ship pilotage, applying Grey theory analysis, brings forward the Grey Theory Analysis Model in ship pilotage risks analysis, Moreover, fuzzy function is taken in the analysis of relative risk factors, achieving the optimal relational coefficient of piloting risk factors, and finally obtaining the relational degree taxis. As indicated in the computing...
The YZ4105 diesel engine cylinder liner was analyzed by using of finite element analysis software ANSYS. Taking into account the basis contacts of various components, this paper calculated the stress and displacement distribution of cylinder liner under the function of heat - coupled structure, and provided a reference for improving a design.
Ecological assessment of highway network development plan is performed to reduce the influence for natural environment. Analytic hierarchy process and fuzzy theory is applied to ecological assessment of highway network development plan. The assessment indices model for ecological assessment of highway network development plan is given firstly, ecological assessment model of highway network development...
