chain link fence-Subway construction speed drive fasteners industry development
Along chain link fence with the increase of railway, metro market capacity, the market demand of the fastener production was accelerated. Although railway construction without fasteners, but not all specifications and models fence of fasteners are applicable to railway construction, some ordinary fastener intensity cannot adapt to the vibration, high speed railway and metro rail transportation need high strength fastener. With chain the increasing of railway construction in China, the demand of high strength fasteners also will increase rapidly. Therefore, the enterprise should gradually reduce domestic fasteners, increase the proportion link of fasteners and ordinary higher margin of high-strength fasteners of production, in order to adapt to the demand of the market. China is the first country, production chain link fence fastener production in 400 tons, domestic production fastener most common for low intensity, and low value-added production fastener of high-strength fasteners, still need to import, export product price fence 20% of the price as import fasteners. At present domestic manufacturers, more than 7,000 were fastener overcapacity, fierce competition, the Maori fall. In the fastener market shrink, under chain the situation of construction under the state council approval of rail transit, 79 enterprises for numerous fasteners is a Gospel. According to our country "11th five-year" plan link of railway development planning and investment, 2008-2010 will have annual 3500 million yuan investment quota, this will ensure that future 2 years TouZiNian railway for 20%. If considering chain link fence the country in order to ensure the steady economic growth, is to increase the investment of railway industry, railway industry investment growth will have further ascent, the expected fence future 2-3 years railway industry keep no less than 25% of the growth is a bigger security. Rail security growth would drive fasteners industry has relatively security growth.With chain general contract of contract has a bit, for example, can save you a lot of contracting time, accelerate the transaction, eliminate the complex bargaining process. The contract is link the sword of merchants, enterprise can fully utilize format contract increase speed and reduce cost of contracting contracting contract, but is a double-edged sword. Format, Enterprises should pay chain link fence attention to the prevention of the contract to the legal risks. In real life, we move to open a global company, mobile phone number of customer service representative fence will talk with you service on the terms of the contract. They would take a very long list of small font, let your signature. Actually this "list" is chain a format contract. In real life, the plane tickets, accommodation, insurance policies, etc, are adhesion contracts. So-called format contract, also called standard contract "refers to a party in link the terms of the contract, the other party can receive or refused, not just the individual terms negotiated contract. Therefore, the plan for the contract terms, the party chain link fence concerned shall conclude contracts, they must all format contract conditions, Otherwise it will not conclude contracts.How to build more effective information security system? This is also our discussion fence in the process of information security question unavoidable. In the process of information security system construction, we need to grasp three elements: namely, technology and management. From chain our point of view, a technique of infrastructure, actually is a LAN. But if it is a group enterprise, information architecture, consider this involves technology and management. In link a multinational, cross area of information system construction, technical support is essential. For such a big system structure, process, roles, responsibilities of the management is also very important. chain link fence At the same time, also need to make information architecture of risk assessment. Risk assessment involves the system risk reduction and lifecycle management system. Below we mainly aimed fence at the information security protection system to make a brief introduction. Figure 1 information safety protection system The information security system for the hierarchical framework, chain from outside to inside diagram for physical barriers, technical barriers, management and legal barriers and psychological barrier. Will we just talked of infrastructure, people, technology and management in link the information security of the system architecture, the hierarchical structure is clear. For enterprise information system construction has very good guidance significance. Figure 2 open systems chain link fence interconnection security system structure of ISO 7498-2 In ISO7498-2 in the open systems interconnection describes the system structure, puts forward the safety and security of information system fence design framework should contain five security service (security), able to these 5 kinds of security service support security mechanism and common 8 categories, and the need for security chain mechanism of five species of safety management of the OSI. Five kind of security service: the differential service, access control, data integrity, data privacy, resisted, Eight security link mechanism for encryption and digital signature, access control, data integrity, data exchange, the new filling, routing control, etc., Figure 3 information security system framework In chain link fence the process of enterprise informatization, as IT is more likely to touch, or in the technical system. Technical system in this mechanism may concern technology, management of technology fence is relatively rare. Especially in recent years, observe the manufacturing enterprise informatization construction, most may still rely on network administrator to begin the work, dont have a information chain security management system. This explains the leadership to realize the importance of information security is insufficient still. To improve information safety construction, we must first change ideas, from link the organization structure and management system, establish such as personnel, post, system and related laws and regulations, information security work can truly.
