Research on Strategic Supplier Selection and Evaluation Standard System of Manufacturing Enterprise

With the market competition aggravating, strategic supplier of manufacturing enterprise is becoming more and more critical for the success of manufacturing enterprise. It plays decisive role in the areas of product quality, date of delivery, service, etc. At present, there are many methods on selection and evaluation of strategic supplier of manufacturing enterprise. But, there lacks of integral system. Through the establishment of outsourcing criteria to supplier classification based on products, this paper builds selection and evaluation standard system of strategic supplier of manufacturing enterprise in order to provide reference to manufacturing enterprise on choosing strategic supplier.

The Evaluation of Braking Performances of Mechanical Brake System on Oil Rig

This paper proposes a novel method for evaluating the braking system on oil rig. The Evaluation indexes, braking capacity, response speed control accuracy and braking efficiency, are put forward according to the drilling safety, benefit, quality and so on. The experimental apparatus to the performances of brakes was built by measuring the relation between the braking pressure, torque and rotation speed. The performances of pneumatic disc brake, hydraulic disc brake and pneumatic band brake are researched by modeling, theoretical analysis and experiment. Based on quantitative analysis, the value analysis is used to quantitatively and qualitatively evaluate the indexes. Some suggestions were put forward for selecting the braking system according to the evaluation. The total evaluation standard system is first proposed and it avails to optimize and evaluate the braking system on oil rig and its automation. Traditional selective method based on experience can be revised and the conclusions also provide a new reference for researching the automation of braking system and other mechanical systems.
