Grey relational analyses are applied to determine the suitable selection of machining parameters for Wire Electrical Discharge Machining (Wire-EDM) process. The Grey theory can provide a solution of a system in which the model is unsure or the information is incomplete. Besides, it provides an efficient solution to the uncertainty, multi-input and discrete data problem. According to the Taguchi...

The theory instrument of grey relational analysis is grey relational grade between the sequences. The grey relational grade is a measure of the degree of association between two factors, or between two systems. It describes the relative changes among the various factors in the development process of the system. In turn, we can calculate the grey relational grade, compare and judge the grey rela...

At present, the supply chain is the last field, which can make enterprise reducing cost and improving flexibility. How to construct the supply chain successfully has received much attention and logistics outsourcing has become common among large manufacturers. The information age and globalization are forcing companies to place a premium upon collaboration as a new source of competitive advanta...

Bacteria are tiny living things that like to attach to surfaces. Most bacteria are harmless, but if the harmful bacteria get into the human body where they do not belong, they can cause an infection. Infections make the human body very sick. Most infections with bacteria can be cured by antibiotics, but not infections caused by biofilms! Biofilms are communities of bacteria living together and ...

The core objective of the integrated curriculum of compulsory education is to “enable students to demonstrate their network-talents instead of just scoring high on independent exams.” The key to determining education reform strategies in the e-era is to establish network-competence indicators for educational behavior in primary schools. We propose a MCDM means for evaluating, comparing and impr...

The grey theory mainly works on systems analysis with poor, incomplete or uncertain messages. The popular grey model, GM(1,1) is efficient for long-term port throughput forecasting. However, it is imperfect when the throughput increases in the curve with S type or the increment of throughput is in the saturation stage. In this case, the throughput forecasting error of grey system model will bec...

Authors explored grey-matter density in 29 methamphetamine abusers and 20 healthy comparison subjects using voxel-based morphometry. Grey-matter density changes and performances on the Wisconsin Card Sorting test (WCST) were also compared between 11 short-term (<6 months) and 18 long-term (>or=6 months) abstinent methamphetamine abusers. Methamphetamine abusers had lower grey-matter density in ...

International incoming grey traffic is currently one of the most important issues for both the Regulator and legal telecommunication operators in Pakistan. The major reason for higher grey traffic in Pakistan is because of international settlement rates which are higher than the cost of domestic termination rate. The grey traffic operators gain financial advantage by offering low international ...

Abstract: Aimed at the situation that the plan attribute value is a three-parameter interval grey number and that attribute weight is uncertain, a three-parameter interval grey number multi-attribute decision making method based on information entropy is proposed. In this study, we combine the three-parameter interval grey number decision-making problem with information entropy, build the dista...
