Logistics Center Goods Research In Packing And Loading Problem

Logistic technology of marching toward 21st century is not only the"commercial logistics"of enterprise's strategy, but also the "sociallogistics"that realizing the supply of the materials to the whole society,and the pluralism network essential "global logistics"during the keencompetition of the globalization market. Can predict, the 21st century willbe the era in which the internationalized logistics have great developments,the logistic industry of this era will appear informational,networked,intelligent,the flexibility,standardized and socialized characteristic.In recent years, the logistic management was introduced from thewestern developed country to our country, and had caused the domesticextensive attention concern. Some large-scale manufacturing companies,merchandising concern,transport enterprise,storage enterprises andinformation industry etc, are setting about studying the theory of logistic,implementing the logistics management, and have made better result.Some manufacturing enterprises begin to change direction and seek to betransported and organizing the delivery service in the whole country withthe products for it by professional transport enterprises. But overall, thelogistics management is still a new concept to most Chinese enterprises.The main reason causing this current situation was the "big and the whole,small and comprehensive"production mode of enterprise which wasformed in the planned economic system of our country for many years.This kind of mode caused every unit to form the situation in which thedepartment was self-sufficient, at the same time this mode made thelogistic market present the closed statement of goods source, this is animportant reason causing the social logistic specialization service degreeat present of our country to be low. Practice has proved, market economyneeds organization ,scale and systematization of higher degree, urgentlyneeds to strengthen building high digitalization,informational logisticdelivery center as soon as possible. Developing informational,modern,socialized new-type logistic delivery center is the important content ofnew-type circulate system under the condition of setting up and perfectingthe socialist market economy.The Goods of Packing and Loading Problem is an important partexisting universally during the cargo transportation process , It is aprogramming problem existing abroad in the production and transportationrealm. Giving a reasonable loading pattern,and delivering the reasonablequantity for the customer, sending the minimal vehicle quantity, so thetransportation time of the delivery vehicle is little and the transportationexpenses is low, then can increase the volume utilization of the container, toget rid of the blindness of the artificial lading. It will bring great profits tomany industries.From the theories angle, studying and solving the goods of packing andloading problem will also affect many realms optimize the strategy problem.It is actually assembling problem of a three dimension physical spaces. Fromthe generalization, not only the physical space exist the assembling problem.If we abstract the assembling problem,will discover the research to thisproblem and also adapt to other many realms, this kind of furthercomprehension infuse into the new vitality for discuss this problem. At thesame time, also provided the method to settle many other same kinds of threedimension layout problems( such as the layout of mechanical accessory andparts of electronic apparatus).The Goods of Packing and Loading Problem is categorized as discretecombinatorial optimization problem with strong application background.Except for its intrinsic NP-Complete computational complexities, thegoods of packing and loading problem also involve many constraints andthe geometric complexity of packing objects and container. Therefore, it is...
