This study investigates the general framework of the decisions in in-plant milk run systems, and also the other related decisions that affect or affected by milk run systems. Emphasis was placed on lean-oriented decisions and objectives. This was accomplished conceptually using extensive literature review. The study shows that there is a lack of studies regarding in-plant milk run system as a whole,...
The research based on multi-depot RVRP with road capacity dynamic constraint. Building relevant mathematic model, and brought simulated annealing mechanism into chaos genetic algorithm. The simulated result shows that the proposed algorithm can be applied to solve this problem.
In this paper we study the path choice problem of material transportation in emergency based on the analysis of fuzzy concept. The effect of fuzzy factors on road is mainly considered to obtain an optimal calculation of path choice. A routing model with random probability for emergency rescue center is proposed with utilization of the theory of uncertain programming with fuzzy probability. The uncertain...
Based on in-depth investigation and study of product distribution system of a food factory in Nanjing city, the distribution status including distribution of the enterprise product line, distribution volume and vehicle utilization were analyzed and existing problems were pointed out. Strategies were put forward according to the factory distributing status, to help improve vehicle efficiency and reduce...
This paper is aimed to research into military vehicle scheduling problem (VSP) by using ant colony algorithm. A vehicle scheduling model with time windows was built up based on the objective of minimum transportation distance, and the model characteristics and application prospects was analyzed. Based on local search strategies, traditional ant colony algorithm was improved. Then the algorithmic procedures...
The ??distribution?? mode for material support is the trend of military logistics evolution, and scheduling of vehicle is crucial to achieve this target. The mathematical model for the vehicle scheduling problem of military material distribution was formulated, in which the minimization of the armies' waiting time was used as the objective, and an improved ant colony optimization algorithm was utilized...
This paper considers the problem of planning the logistics of distributing medication to points of dispensing (PODs), which will give medication to the public. Previous work on a two-stage routing and scheduling approach showed that it can generate solutions with reasonable minimum slack. This paper presents a delivery volume improvement algorithm that can increase the minimum slack of a given solution.
