ITIL is a large collection of best practices, tools and methods used in the management and handling of IT services. It's composed of five books related to the most important IT management fields. In this paper, we will place the emphasis on the Service Operation field in ITIL and more precisely, on the incident management process used for managing the life cycle of IT incidents. The main idea is to...
A commonly used technique for oil spill response is to use two or more ships towing a boom. Our research proposes fully automated operations based on unmanned ships and a computer-based planning system. The system will carry on a complete autonomous operation, requiring only the position of the oil-spill and to push a start button. The paper describes the steps of the research already accomplished,...
This paper is devoted to a centralized mission planner for a group of marine robots. Mission is considered consisting of straight line segments (usually called tacks). The planner takes segments spatial configuration into account and solves a problem similar to the Multiple Travelling Salesman Problem (MTSP) in order to assign a sequence of segments to each vehicle. The contribution of this paper...
Part I of this paper proposed a development process and a system platform for the development of autonomous cars based on a distributed system architecture. The proposed development methodology enabled the design and development of an autonomous car with benefits such as a reduction in computational complexity, fault-tolerant characteristics, and system modularity. In this paper (Part II), a case...
This paper presents a computational model capable of improving the action policies for a well-defined domain. Each action policy is represented as a driving plan P, which is composed of a number of actions {a1, ∶ an}. These actions can be used to move a train in a stretch of railroad Sti. The plans are elaborated using a CBR approach and reusing previous solutions and learning from plans. The CBR...
The deployment of efficient roadside networks is a necessity for ITS deployment. The main challenge for the roadside deployment is to find a satisfying or best distribution of RSUs on the roads network according to the given conditions in order to meet the requested requirements of the roads operator. Additionally, various factors affect this process such as traffic, infrastructure and topological...
This article discusses about the application of unmanned vehicles networks in several areas related to power systems. The main topics are related to the planning and mission control tools as well as coordination, communication and data sharing between the associated nodes. Throughout the work, some vehicles developed in the Underwater Systems and Technology Laboratory (LSTS) will also be presented,...
A methodology to estimate the energy consumption of an electric vehicle is presented. An approach to create a driving cycle based on data extracted from road planning software is developped; it is used to forecast the total cycle energy consumption. Results are compared to the ones obtained from the corresponding actual driving cycle. The influence of road elevation is taken into. Results match with...
Historically the EV market has focused on providing services such as charging infrastructure based on master planning in the hope that end users will want to use the provided assets. This model has been shown to fail in certain instances with stranded assets and non-viable business models. This paper demonstrates how Route Monkey is working with partners to create demand within fleets for the deployment...
Planning and control environments for automated guided vehicles are predominantly dedicated to specialized vehicles, e.g. special carriers used in harbor areas for the transport of containers between quays and stackyards. The environment is completely different for commercial standard vehicles when operated under automated guidance. Typically, these are articulated vehicles with a high degree of variability,...
In March and April 2010, an ISE Explorer Autonomous Underwater Vehicle (AUV), built for Natural Resources Canada (NRCan), was deployed to Canada's high Arctic. Its mission was to undertake under-ice bathymetric surveys in support of Canada's submission to establish the outer limits of its continental shelf under the United Nations Convention on the Law of the Sea (UNCLOS). During this deployment several...
Both areas, airline planning and railway planning, have attracted a significant interest from the operations research and optimization community during the past decades. Although both areas have significant similarities, i.e. transport of people and goods according to specified schedules, the dissimilarities seem to prevail due to the mostly separate developments of these fields. In this paper we...
Today a large number of autonomous underwater vehicles (AUVs) are evaluated or operated all over the world. Most of them use their own control systems created by the vehicle's manufacturer or scientists of different research areas. The Fraunhofer Application Center System Technology currently owns three underwater vehicles (both AUVs and remotely operated vehicles, ROVs), a forth is under development...
This paper discusses the autonomy framework proposed for the mobile instruments such as Autonomous Underwater Vehicles (AUVs) and gliders. Paper focuses on the challenges faced by these clusters of mobile platform in executive tasks such as adaptive sampling in the hostile underwater environment. Collaborations between these mobile instruments are essential to capture the environmental changes and...
In this paper we demonstrate a method for obstacle avoidance of heterogeneous unmanned marine vehicle teams. The task is to find a collision free path for a vehicle group moving in close formation through an area with known obstacles, while keeping formation when possible and change formation when necessary. Whenever possible, they shall use their original paths in desired formation, as only this...
Today, due to the current state-of-the-art of embedded systems, underwater robotic vehicles are limited in both, their autonomy and capabilities. In order to increase their utility it is advantageous to run multiple vehicles at the same time whereby each vehicle serves as individual node in an underwater network. In this context a group of leading European vehicle manufacturers and researchers set...
Worst case execution time analysis based on measurements requires large test suites to obtain reliable numbers. We are thus developing tools to efficiently generate these test sets in a whitebox-testing approach. To make project progress measurable and guard against regressions, a benchmarking suite is sought for. We present a set of requirements that have been collected and outline the design of...
