Study On Optimization In Our Country Import Pitch Purchase And Transport Model

Since reform and opening-up, the sustained and rapid development of our national economy, highway transportation increases sought-afterly, So road construction especially expressway are built and developed rapidly, 1st expressway of our country would topped 10, 000 kilometers by 1999 , top 20, 000 kilometers in 2002 since 1988, The expressway mileage up to 50, 000 kilometers by 2010 according to planning, and is up to 70, 000 kilometers by 2020, Form the national high-speed network of highways basically.The construction of the expressway needs high-quality a large number of to accord with the pitch which standardize the request, A large number of expressway recoverable amount is expected much too, And of our country petroleum refine technological level there is sure disparity compared with advanced country's level in the world, Performance its difficult to meet fast, heavily loaded traffic and different climate request of terms, So in situation have heavy change and educational level have heavy prerequisite of improvement, Can only rely on import under prerequisite that import volume increases fast year by year, pitch of our country,, Import to our country pitch get the new demand out of in purchasedding, transported, supplied etc., And dimple a lot of and can't meet the new situation, respect of the new demand from it.This text foundation the above situation analysis our country import pitch every situation and existing problem of link at present, Especially all link expenses remain high and influence of our country construction cost of expressway serious, Import through our country pitch transport demand analysis of influence factor at the same time, The screening ofdifferent prediction methods , come to predict the trend that our country imports the pitch and transport demand. In a situation that this imported product demand will also be improved further in the following several years, Must optimize system this purchase, transport, load and unload, store, dredge competence of link of transporting etc., Introduce the advanced idea and method on the materials supplies of expressway construction abroad, Adopting more advanced modern material flow thought on the software, the pitch is provided and deliver to constructing; Develop performance excellent keeping the tank wagon warm with low costs on the hardware; Supply the barge special-purpose and in bulkly ; The special- purpose pitch shipping dock stores pot, etc. to equip, thus propose that the transport way in which our country imports the pitch is chosen, And use the economic technological demonstration method to carry on the demonstration of economic technology to these ways, Therefore get our country out of and import the imagination of transporting way reform of pitch , Propose and purchase and concentrate on and melt, transport in bulk to take the whole province or the whole country this supply platform and accord with international advanced transport suggestion of technology in unison.Our country import pitch rational advanced, transport choice, serve expressway construction of our country, Other chemical product in bulk to melt to transport and probe out a road to succeed for our country even on the other hand, Play the exemplary role, therefore produce the enormous economic benefits and social benefit.
