The Study On Selecting The Subcontractor In The Marine Engineering Enterprises Based On The Methods Of GAHP-DEA

The marine engineering enterprises’ contract production mode is labor subcontractor,that’s why select an labor subcontractor is considerable critical to them.With the increase of order,marine engineering enterprises have faced a lot of questions.For example,how to find out an high-quality labor subcontractor to help marine engineering enterprises to satisfy the clients;how to forage one who have lower prices,and lower costs which leads to a higher profit to the marine engineering enterprises.The traditional means of selection is to give each labor subcontractor a score within 0 to 100,and the indexes contain the qualification,the quality management system,the quality control,HSE,the process capability and the credit status.Actually,this way can not show the real ability of production and risk control.Provided that labor subcontractors have some safety problems,environment contamination,product quality problems and process postponed,the marine engineering enterprises will suffer from incredible costs,the risk of reputation,the risk of lost client’s trust,even lost the order.In fact,choose a high-quality labor subcontractor means a lot to the marine engineering enterprises,it could enhance its status in the world.The main content as follows:(1)The traditional way choose labor subcontractor and the existing problems.To describe the traditional labor subcontractor selection process,the index system and model,analysis the marine engineering enterprises problems existing in the traditional labor subcontractor selection process and indexes.(2)Construct the labor subcontractor selection process and the index system.First of all,setting up labor subcontractor selection principle of index system;building the selection process.According to the basic standards of selection of labor subcontractor,removing some labor subcontractors;Then,based on the purpose of operation,setting up the labor subcontractor selection index system,which contains two layers indexes.The first layer of indicators are cost,process,quality and safety and environmental,the second layer of indicators have 12 indexes.Finally,according to the new index system of labor subcontractor for the final selection.(3)Construct the labor subcontractor selection model and using GAHP-DEA.First,introduce GAHP method and DEA method.Then,combine GAHP(Group Analytic Hierarchy Process)and DEA to construct the labor subcontractor selection model.(4)Comparison of the traditional way and the new way.Selecting the same decision maker to assess the same labor subcontractor.Then,compare the result of the old and the new way to approve that the new way is better than old one.On account of it really solve the problems in old way,and satisfy the operating requirements of Marine engineering enterprises.Finally,for guaranteeing the new way can be well carry out in the marine engineering enterprises,proposing that set selection and evaluation team,the status of selecting decision maker,the publicity of indexes,help subcontractor developed in the future,construct subcontractor system,perfect the selection of subcontractor system,these six suggestions.
