Abstract (in Japanese) (See Japanese page) 
(in English) The vehicle routing problem is the combinatorial optimization problems which aims to determine the delivery routes of the vehicles to satisfy the demands of the customers.
Then the objective of the vehicle routing problems is to minimize the number of vehicles used to construct the feasible solution and the total distance.
Also,the vehicle routing problem is one of the $mathcal{NP}$-hard problems,then,a sophisticated algorithm is strongly desired to propose to solve the problems efficiency.
The vehicle routing problems are categorized into some types of the problems.
For example,the vehicle routing problem with time window is that each customer has the time window that the vehicle should be visited.
Also,in the capacitated vehicle routing problems,each vehicle has limit to mount the service of the customers.
In this paper,we propose the local search method with which the 2-opt and Or-opt methods are combined for the capacitated vehicle routing problems.
From the results of the numerical simulations,we reveal that the proposed local search method has higher performance than the conventional local search method.
