Research On Wood Structural Material Product Certification System In China

Based on the foreign timber structure management system,the current situation of the use and management of timber structure in China were analyzed.The necessity,feasibility and adaptability of certification for timber structural products in China were studied.The certification system,certification risk and enterprise coping strategies of timber structural products in China are expounded.The certification of quality and cost benefits of timber structural products were analyzed baed on equilibrium game model and cost benefit mode,and the certification system of timber structure products in China was established.The main results of this research are summarized as follows:(1)Compared with the management system of structural timber in developed countries,there are still some problems in our country,such as lack of resource matching,standard system need to be perfected,use and management need to be unified,and product certification system need to be carried out.From the four aspects of international integration,industrial development,standardizing the market and ensuring safety,it is very necessary to implement certification of structural timber products in China.From the four aspects of certification system,industrial demand,localization needs and timing,it is feasible to implement structural product certification in China.(2)Carrying out certification system of structural timber products,adapt to the policy system in China,adapt to the development of wood structure industry and meet the needs of timber structure market,is a powerful way to solve the problem of quality assurance of timber structure.Based on SWOT analysis,it is necessary to establish the admittance of the product certidication of timber structural.It is necessary to promote the credit guarantee function of product certification and encourage enterprises to participate actively.According to the different uses of structural timber in wood structure,combined with the present situation of structural timber production enterprises in China,we should adopt a strategy of implementing certification system successively.Because the quality of structural timber is related to the safety and life of wood structure,we must adopt the mandatory product certification system.(3)At present,the standard system of structural timber has been initially constructed in China,which provides a technical basis for the certification of structural products.However,there are still some problems such as imperfect standard of structural timber,inconsistent standard technology,and inconsistent standardization process.Under the certification system of China,established the basic system structure of important material product certification,inspection and testing agencies,certification activities,personnel certification,and certification of important structural material products to implement the rules of clear structural material authentication unit,basis and related factors.In the implementation process of certification system for structural timber products,China should adopt policies such as government's incentive policy,establishment of government,industry and enterprise's active cooperation mechanism,promotion of mutual recognition of structural product certification,and enhancement of certification credit function.(4)The risk of structural timber certification is mainly divided into two categories: the risk factors of authentication system and the risk factors of production enterprises.Through the analysis of risk management,the impact grade,occurrence probability and serious grade of all kinds of risks are clearly defined..In Borda ordinal value analysis,product quality consistency risk is the most serious among all risks.In the certification system risk,the authentication behavior risk level is the highest,and the management of these two types of risk should be strengthened.(5)In the implementation process of product certification system,China's structural timber enterprises should pay close attention to industrial information,respond actively and actively,set up enterprise quality management system and improve management level.In response to the certification system of structural products,enterprises should strengthen the construction of elements such as facilities,technical personnel and factory quality assurance capabilities,so as to ensure that factory hardware and software meet the requirements of Certification Implementation Rules.(6)Based on the equilibrium model analysis,government regulation plays an important role to improve the quality of product certification for the timber structure products.The punishment mechanism and the quality exposure can effectively reduce the collusion between the structure material enterprises and certification agencies collusion false certification,so as to promote the quality of identification in the game.Through cost-benefit analysis model,structural material product certification should pay more attention to the long-term benefits,the government departments and industry organizations should actively promote the social benefits of the structural material product certification,enterprise should pay attention to the profit balance point in the development of product certification,improve the ability to resist risks,effectively control production.
