Research on Selection of Special Shell Materials based on Cluster Model and Analytic Hierarchy Process

Abstract

The container shell has a good heat dissipation effect in seawater. In this paper, the selection of Marine container materials is further optimized by considering seawater's depth, density, corrosion and the materials' cost. By analyzing various characteristics of materials, we select important factors that affect material selection. Through cluster analysis, the decision-making factors are classified into three systematic evaluation indexes: service life, material cost and heat dissipation effect. This paper uses the analytic hierarchy process to analyze and establish the correlation between different factors. The influence weight of each characteristic factor of material on the decision of material selection is calculated by constructing the judgment matrix. According to the weight ratio of various factors, we find that the selection of container shell material pays more attention to the characteristics of material pressure resistance, material composition and material density. Finally, we selected a better scheme by referring to the properties and uses of several materials in relevant information: Radiator structural material can be selected Inhibited Admiralty Brass, High Silicon Bronze A, CDA 655, we can use Inconel 625, Titanium 6Al-4V, Beryllium-copper, or CDA 172 to protect the server.
