Mixture transportation : cement stabilized macadam should be transported by dump truck , and the quantity of dump truck should be reasonably prepared according to the paving capacity of the pavers , production capacity of the mixers , and the distance of transportation 混合料运输,水泥稳定碎石的运输均采用自卸车运输,运输车的数量根据摊铺机摊铺能力,拌和机生产能力及运距进行合理地调配。
It is fulfilled two actions , conveying concrete and mixing concrete . these actions not only ensure the quality of the concrete , but also make the conveying distance longer . but in the northwest area of our country , research on the field of the truck mixer is little 它兼有载运和搅拌混凝土的双重功能,可在运送混凝土的同时对其进行搅拌或搅动,因此能在保证输送的混凝土质量的同时适当延长运距(或运送时间) 。
This paper , based on the theory of marketing and the theory of enterprise strategy , aiming at the characteristics of guangdong provincial market of passengers transportation , systematically analyzes the opportunities and threatens , superiorities and weaknesses that guangzhou rail ( group ) co . will face in guangdong districts during its management and distribution of passenger market , and classifies and settles the position of objective market of guangzhou passengers transportation by rail , and further suggests the strategy of management and distribution of market of guangzhou passengers transportation by rail , including strategies of production , of price , of distribution and of promotion and etc . at the ending part of this paper , the writer summarizes the strategy that guangzhou rail passengers transportation should take in guangdong province 以此为基础,对广东客运市场进行了市场细分,明确了广铁集团客运的目标市场是: ( 1 )充分发挥中长距离优势,进一步开拓、巩固和完善中长途客运主体市场,以运距800公里? ? 1500公里的夕发朝至、朝发夕至列车为客运名牌产品,巩固直通客流市场,并努力开发高档次的客运精品市场; ( 2 )以珠江三角洲主要城市向外辐射300公里左右的短途客运市场为重点,以快速城际列车和“公交化”列车为“拳头”产品,吸引短途客流; ( 3 )适应人们对度假休闲需求日益增加的需要,大力开发旅游列车、假日列车等新兴的特色客运产品。
On one hand , due to information flow ' s impact on information circulation , the development of information flow leads to avalanche of trade partner , enlargement of international market , rapid acceleration of logistics amount , build - up of transportation safety assurance , enhancement of transportation service quality and helps to accelerate the development of logistics ; on the other , information flow leads to the decrease in personnel flow , shortening of average transportation distance , tendency toward zero inventory and remodel of the traditional logistics 信息流的发展一方面由于促进了信息的流通,导致了贸易伙伴大量涌现、国际市场扩大,物流量的激增、运输安全保证的增强、运输服务质量的提升,从而促进了物流的发展;另一方面,它导致了人员流动的减少,平均运距的缩短,零库存趋势,从而冲击了传统的物流业。
