How to write a lump coal transportation proposal? Bidding with

A, the task Guangdong Meizhou has a cement factory (location: about 5 km from the city) from Datong, Shanxi, bought coal (quantity 80,000 tons) supply time of 6 months. Now entrusted a logistics company responsible for the logistics transport of this batch of goods, now suppose you are the logistics company's logistics director, from the point of view of the lowest cost, the preparation of coal transportation program to the cement plant for review. Requirements to have three programs, and compare their advantages and disadvantages, put forward a recommended program. Second, the program design Specific routes such as Figure 1, 2 1, cargo size specifications Coal properties: coal can be adsorbed in the air at room temperature and oxidized oxygen, generating a certain amount of heat. If the heat generated by oxidation is less and can be lost in time, the coal temperature will not rise; if the heat generated by oxidation is greater than the heat lost to the surrounding area, the coal temperature will rise. As the coal temperature continues to rise, the oxidation speeds up sharply, which generates more heat and the coal temperature rises sharply. When the coal temperature reaches the ignition point of 300～350℃, the coal will ignite spontaneously. Coal will produce coal dust escaping during loading and unloading Coal packing specification: no need to pack, can be directly loaded on the truck Coal storage conditions: coal in the loading process, the cargo hold must be leveled to avoid flammable gases accumulating in the pits and puddles, and ventilated at regular intervals. Spraying the dust source sprinkling or spraying chemicals to increase the viscosity and weight of dust particles to eliminate or prevent dust 2, transport routes (1), Option 1: the shortest time the whole road transport: about 2,190.3 kilometers Figure 1, Erguang Highway G55 Erguang Highway Taiyuan City, Beijing, Hong Kong and Macao high Jiaozuo City, G36 Xuchang City, Ningluo Highway Zhoukou City, Huangshi City, turn the Fuyin Highway Nanchang City, G206, G35, turn the G25 Ruijin City Meizhou City Figure 2 (2), Option 2: the shortest distance road transport The whole distance: about 2154.1 kilometers Specific route: as Figure 1, 2 Beijing-Kowloon Line Road Shanxi Datong Longchuan (3) Option 3: Railway Transportation Guangmeishantan Railway The whole distance: 2,613 kilometers The time required: about 35 hours Meizhou Specific Route: as Figure 1 Figure 14.Comparison of Programs (such as Table 1) Option 1 Option 2 Option 3 Road transport Option 1 Option 2 Option 3 Road transport, moderate distance, time Road transport, short distance, time Railway transport, the longest distance, short time, moderate cost Shortest, least cost Longest time, maximum cost Table I III. Transportation with the car scheme Option 1 and Option 2 is road transport, mining dump trucks are also known as dump trucks . (Figure 1) A truck load capacity of 30 tons, a distribution of 1,000 cars, 5 times. Figure 1 Option 3 Railway transportation, carried in train wagons. A wagon has a capacity of 60 tons, and 20,000 tons are transported in 4 shipments. As Figure 2 Figure 2 IV. Transportation safety and security Road transportation safety and security: highway, highway bridges, highway tunnels, load limit, height limit, width limit, length limit standard adjustments, highway management agencies, highway operators should change the load limit, height limit, width limit, length limit signs in a timely manner; need to detour, but also should be marked detour routes; highway management agencies for approval of the application for overloaded transport, should be based on the actual situation of the passage of the route, the need for reinforcement, renovation measures. Need to take reinforcement, transformation measures, you can sign a relevant agreement with the applicant to develop appropriate reinforcement, transformation program; vehicles should be standardized loading, loading shall not touch the ground drag. Vehicle loads are easy to fall, spilled or scattered, should be taken compartments closed and other effective protective measures before driving on the highway; traffic accidents caused by highway, highway accessory facilities damage, the public security organs of the traffic management department in dealing with traffic accidents should be timely notification of the relevant highway management agencies to the scene of the investigation and processing. Railroad transport safety and security: railroad lines on both sides should be set up railroad line safety protection zone; in the railroad line safety protection zone, in addition to the necessary railroad construction, operation, rescue activities, any unit or individual shall not carry out the following acts; demolition of buildings and structures in the railroad line safety protection zone shall be given reasonable compensation in accordance with the law. However, the demolition of illegal construction of buildings, structures, except; railroad transportation enterprises should be the safety management personnel of the railroad line for regular inspection and maintenance; any unit or individual shall not be in the railroad bridge (including roads, railroads, dual-use bridges, the same below) across the river upstream and downstream of the 1,000 meters within the reclamation of paddy fields, extraction of groundwater, dams, pontoon bridges, and the construction of other impacts or Endanger the safety of railroad bridges; road, railroad bridge piers, beams and other *** use part of the test, maintenance by the railroad transport enterprises and road management departments or road operating enterprises *** together responsible for the costs shared in accordance with the principle of fairness and reasonableness; tracked vehicles through the railroad level crossing, should be notified in advance of the railroad crossing management department, and in its assistance, guidance through. V. Contingency plan (how to deal with problems) (1) Contingency plan for emergencies: keep the communication unimpeded, and do the capacity scheduling work at any time. Timely contact with the transportation company to seek ways to deal with the problem; (2) Emergency plan in case of heavy rain, flooding, landslides, foggy weather and other factors causing road blockage: once the road blockage is caused by the above reasons, the Transportation Management Office should get in touch with the highway department, the traffic police department, the meteorological department and so on, and report to the superiors and carry out timely treatment; (3) Emergency plan in case of the vehicle breaks down on the way: when the transportation vehicle breaks down on the way. Transportation enterprises should get in touch with maintenance enterprises in a timely manner, send competent forces to the scene of emergency repair to ensure the timely delivery of goods; (4) the occurrence of major events involving industry stability and other contingency plans: to do a good job in maintaining the stability of the transportation industry, we must investigate the factors of instability, and take timely measures to properly resolve them. Strive to nip unstable factors in the bud through the efforts of all departments to ensure social stability. (5) for sea transportation, first, pay attention to the fog information and ship navigation in the fog precautions, take safety precautions. The second is to take precautionary work, staff to strengthen the duty, according to the fog conditions, to take shore avoidance, prohibition of navigation and other emergency measures, the third is to strengthen the monitoring, through the monitoring system to strengthen the accident-prone sections, dangerous goods loading and unloading terminals, public terminals and other key sections of the real-time monitoring. Fourthly, we have made good preparation for dynamic emergencies, strengthened the 24-hour duty of "12395", and all personnel are on standby to ensure timely handling of emergencies in case of emergencies. (6) On the railroad, in case of emergency, the locomotive should issue the signal of "emergency stop" to stop immediately and cooperate with the train staff to do rescue work. The situation truthfully to the transportation company Six, Conclusion and Recommendations Conclusion: From Table 1, we can see that Option 3 moderate distance, the most moderate time, the most moderate cost. So option three will be your best choice. Suggestions: 1. Railway transportation is best to choose the container transportation, so that the transfer can be more convenient, but also reduces a lot of unnecessary losses. 2. Ventilate regularly to avoid spontaneous combustion.
