Tabu search algorithm is proposed for the vehicle routing problems with time windows. In the process of solving, Several initial solutions are randomly constructed, Meanwhile, adjacent structure is constructed by using double operation. Under such condition, the length of tabu list is changed by the resulting linear relation, which can improve the whole capability of optimizing. The applicability...
According to the characteristics of multi-variety and freight loading problems with priority, establish target function fully utilizing capacity and cubage of loading tools. And solve this type of problems utilizing improved hybrid genetic algorithm from the overall situation. Firstly, adopt binary code so as to make the problem more succinctly. On the basis of cubage-weight balance algorithm, construct...
A new collaborative ant colony algorithm (ACA) is devised to solve Optimal Loading Problem with Category Restriction (OLPCR) for Railway Specific Goods. Improvement is adopted on the basis of former algorithm to optimize the loading capacity and volume of vehicles, besides the least number of vehicles needed in various conditions. Finally an example is put forward and analyzed, proving that the ACA...
In this plethora of increased competitiveness and globalization the effective management of the warehouse system is a challenging task. Realizing that proper scheduling of the warehouses is necessary to outperform the competitors on cost, lead time, and customer service basis (Koster, 1998); the proposed research focuses on optimization of warehouse scheduling problems. This research aims to minimize...
