Abstract
With the rapid development of increasingly fierce market competition, the degree of integration of the world economy and the acceleration of science and technology, many enterprises have logistics as an important means to improve competitiveness and enhance the core competition ability, advanced logistics theory and logistics technology into the enterprise production and management. As an important approach to realize logistic rationalization, research on vehicle routing will help enterprises to reduce logistics cost, improve operation efficiency, enhance customer satisfaction. Because vehicle routing problems in operations research theory and practice closely together, in recent years. Many achievements, once known as the "one" research in recent decades most successful areas in operations research mainly caused by the high cost of logistics transportation and distribution is the emergence of some not some unreasonable transportation and methods, such as convective transport, circuitous transportation, the shortest path transportation and distribution, non - load transport, which will lead to improved transportation and distribution service level, it is very meaningful to the optimization of transportation and distribution problem. This paper mainly from the following aspects of logistics transportation and distribution issues;
