Introduction
Approximately for two decades mathematical models and engineering methods have been available
for predicting shape and hydrodynamic loads of complicate and complex fishing gears.
Therefore engineering methods are still necessary which approximately consider the relevant features of fluid-structure interactions like Priour & Herrmann (2006) did to predict the shape of cod-ends by statistical models.
Test plant, model and measuring methods All tests were carried out in the Large Sub-Sonic Wind Tunnel of the Department of Mechanical Engineering and Marine Technology of the University of Rostock.

Only analyzing the reliability of its supply chain through scientific method and finding out the key evaluation indexes can experts take proper measures to optimize the oil logistics network as well as to improve the whole supply chain’s reliability.
In recent years, the problem of supply chain reliability has been paid more and more attention because of demand uncertainty, especially after Wen Chuan Earthquake in which there are many supply chain problems about material distribution under emergency.
Yuanhong Liu, Ming Luo and Zhongying Liu defines reliability from the view of reliability engineering theory as the magnitude of trouble-free working ability of supply chain system, referring the capability to normally run within certain time in perfect competitative market [2].
Third, find out the key indicators and establish the evaluation index system.

Abstract.
Introduction The interactions of pulsed laser beam with solid materials have raised tremendous interest in the last decades for its potential applications in different areas including surface modification, nanoparticles and clusters production, pulsed laser deposition, chemical analysis, etc[1-7].
Although in the past years, laser ablations of materials have been widely reported, it is rather difficult to model such events[8-12]: the complex interplay of the matrix, ambient and experimental parameters, the difficulties come from plasma spatial inhomogeneity, time variation of plasma shape, which is simultaneously followed by the change of plasma parameters and emission of ablated material in plasma.
Ti-Al alloy has been widely used in aerospace engineering and automobile industry for its low density, good corrosion resistance, thermo stability and excellent mechanical properties.
Two explanations are offered for this observation: under atmospheric pressure, the incident laser beams breakdown the air on the target surface, the air plumes absorb part of the energy and decrease the efficiency of the laser available for target material ablation.

Abstract In this paper, an extended Maxwell-Hellawell numerical grain size prediction model is employed to predict as-cast grain size of inoculated aluminum alloys.
Carozzani et al, Direct Simulation of a Solidification Benchmark Experiment, Metallurgical and Materials Transaction A 44 (2013) 873-887. ], was also applied for grain size prediction [9].
In order to apply their model to any solidification experiments, two key model input parameters, i.e., grain growth rate and nucleation undercooling, have to be known in advance.
