An emergency plan contains the constraints of resource and time. However, complexity and changeability of emergency environment could influence these constrains, leading to both time and resource lose. Aimed to meet the needs of executive time constraint, a model of plan adjustment for executive exception in emergency logistics distribution is proposed in this paper. Firstly, executive exceptions...
The first traffic network distribution based on distribution center problem (TNDBDCP) is put forward, which can not be solved by traditional algorithms. In order to solve TNDBDCP, improved genetic algorithm is put forward based on the idea of global and feasible searching. In the improved genetic algorithm, chromosome is generated to use binary-encoding, and more reasonable fitness function of improved...
With a rapid development of the Chinese economy, there is a huge amount of logistics costs, while China still has not established a pallet associates, and even it has not proposed a practical model of the pallet associates yet. Therefore, the model of Chinese pallet associates is proposed based on the analysis of banking operations as well as the loan of money and the comparison of pallet lease. Meanwhile,...
This study improves the original model of vehicle routing problem by adding some strains such as time windows, volume, weight, as parameters into the model. The model is adjusted to an mutilate-goals vehicle scheduling problem based on the mutilate-goals programming, and study on how the time-windows and time-distinction affects the delivering planning. We use GAMS to simulate and solve this problem.
Joint distribution is a cooperative distribution mode. It has become a trend of logistics distribution due to its inherent characteristics and advantages. In practice, the participant enterprises are quite concerned about the allocation of income and cost caused by their cooperation. So the allocation method will play an important role in the successful implementation of joint distribution. This paper...
