The main purpose of this study is to find out a good solution to the vehicle routing problem considering heterogeneous vehicles. This problem tries to solve the generation of paths and the assignment of buses on these routes. The objective of this problem is to minimize the number of vehicles required and to maximize the number of demands transported. This paper considers a Memetic Algorithm fo...

Modern car-related industry has required a rapid development of a car. Although many functions may be added to meet various requirements, its development time should be shorter. As a result, traditional development methods cannot satisfy the test requirements which not only have various functions, but also take a longer time on performing the test. Therefore, we propose to adopt the existing Mo...

This paper focuses on on-going work in the “Action” project related to the decisional processes that are required to allow teams of cooperating heterogeneous vehicles to achieve target localization and tracking missions. Autonomy is made possible thanks to embedded functions such as data fusion, planning and supervision, organized within each vehicle so that they can cooperate together. Two ess...

A number of critical infrastructures, such as gas or oil pipelines operate in a sensitive environment and any damage done to the infrastructure significantly harms the surrounding fauna and flora and poisons water supplies. The infrastructure thus needs to be monitored and any damage or failure has to be detected and reported as quickly as possible. We focus on the enhancement of the monitoring...

In Japan, inspection of irrigation water canals has been mostly conducted manually. However, the huge demand for more regular inspections as infrastructure ages, coupled with the limited time window available for inspection, has rendered manual inspection increasingly insufficient. With shortened inspection time and reduced labor cost, automated inspection using a combination of unmanned aerial...

We consider a manufacturer’s planning problem to schedule order production and transportation to respective destinations. The manufacturer in this setting can use two vehicle types for outbound shipments. The first type is available in unlimited numbers. The availability of the second type, which is less expensive, changes over time. Motivated by some industry practices, we present formulations...

In this article, work in progress on a system for rapid aerial mapping is presented. We believe that a tool able to quickly generate an up-to-date high resolution aerial view, e.g. shortly after a natural disaster or a big incident occurs, can be a highly valuable asset to help first responders in the decision making. The presented work focuses on the path planning capabilities of the system, t...

This paper describes the design of a supervisory controller (supervisor) that manages multiple heterogeneous vehicles, i.e., multiple controlled and uncontrolled vehicles, to avoid intersection collisions. Two main problems are addressed: verification of the safety of all vehicles at an intersection, and management of the inputs of controlled vehicles. For the verification problem, we employ an...

the studies in aerial vehicles modeling and control have been increased rapidly recently. in this paper , a coordination of two types of heterogeneous robots , namely unmanned aerial vehicle (uav) and unmanned ground vehicle (ugv) is considered. in this paper the uav plays the role of a virtual leader for the ugvs. the system consists of a vision- based target detection algorithm that uses the ...

This paper presents an effective hybrid control approach for building stable wireless sensor networks between heterogeneous unmanned vehicles using long‐ endurance aerial robotic vehicles. For optimal deployment of the aerial vehicles in communication networks, a gradient climbing based self‐estimating control algorithm is utilized to locate the aerial platforms to ...
