Abstract:The site selection of emergency material reserve point is a key problem to solving the distribution optimization of emergency materials reserve. In this paper, according to the characteristics of emergency material reserves, we comprehensively considered the shortest distance, the shortest time, transportation costs, construction costs, storage quantity and other factors, and established the analysis model to make optimization to the reserve point site selection.

A plug-in oil hose joint is used as the research object in this study. Aimed at the problem of pipeline breakage due to insufficient strength of the joint during the process of oil transportation on the sea, a three-dimensional geometric model of the joint is constructed according to the structural characteristics of the plug-in joint. e mechanical properties of the plug-in hose joint were studied by numerical simulations and field experiments. e strength of the joint was optimized by applying materials with different properties and adjusting the circular angle of the joint. e tensile strength test results of the plug-in oil hose joint are consistent with the theoretical analysis, which shows that the method proposed in this paper can effectively improve the tensile strength of the oil hose joint. It is of great significance to expand the scope of the plug-in connector and ensure the safe and stable use of the hose system.
