Abstract The running-in coatings were formed on the surface of tin bronze QSn10-1 by electroerosive alloying (EEA) with soft antifriction materials such as silver, copper, Babbitt B83 and graphene oxide (GO). mass transfer, roughness, coating thickness dry friction coefficient measured analyzed a precision electronic balance, three-dimensional optical profiler, metallographic microscope, scanni...

Enterprise risk management (ERM) has raised increasing concern in the field of risk management, and brought practical revenues to enterprises in today’s complex interrelated global business environment. It is a valuable question for China enterprises how to improve the ERM performance. Based upon ERM implemental goals published by COSO, we user elevant data from non-financial listed corporation...

In this paper, a key node mining algorithm of entropy-CRITIC combined weighted GRA-TOPSIS method is proposed, which based on the network structure features. First, obtained multi-dimensional data students' identities, seating relationships, social and so to build database. Then, similarity among students was used construct in-class networks analyze structural characteristics them. Finally, CRIT...

One of the key elements in production planning hierarchy is master production scheduling. The aim of this study is to evaluate and compare thirteen alternative MPS development methods, including multi-objective optimization as well as twelve heuristics, in different operating conditions for multi-product single-level capacity-constrained production systems. We extract six critical criteria from...

With the development of central-private enterprises integration, selecting suitable key suppliers are able to provide core components for smart complex equipment. We consider from matching perspective, it not only satisfies natural equipment, is also a good implementation equipment project in integration context. In this paper, we carry out two parts research, one evaluation attributes based on...
