With the increasing reliance on space systems for communications, the number of multi-satellite, multimission operators, in both the government and commercial sectors, is also increasing. To prevent the operations and maintenance costs from increasing linearly, or worse, with the number of satellites, operators are attempting to consolidate operations and maintenance across the satellite fleet....
Collective adaptive systems are large-scale resource-sharing systems which adapt to the demands of their users by redistributing resources to balance load or provide alternative services where the current provision is perceived to be insufficient. Smart transport systems are a primary example where real-time location tracking systems record the location availability of assets such as cycles for...
INTRODUCTION In the EU 5 framework project DECADE (2001-2003) a new methodology has been developed to calculate in detail the engine power required to drive a given vehicle over any particular route. It includes the rapidly changing (transient) demands placed on the engine, an area that has proved an obstacle to accurate simulations in the past. Together with the associated speed profiles, the ...
The fleet assignment model (FAM) for an airline assigns fleet types to a set of flight legs that satisfies a variety of constraints and minimizes the cost of the assignment. The through assignment model matches inbound flight legs into a city with the outbound flight legs at the same city that are flown by the same plane types and creates through connections (that is, flight connections with on...
Within the European research project SimpleFleet, a telematics system for fleet management business intelligence was developed, delivering live or near-realtime statistics about individual vehicles or the entire fleet. This supports the fleet manager in ad-hoc decisions and in medium and long term improvements. The fleet vehicles (e.g. taxis, delivery vans) are equipped with an On-Board-Unit (O...
A main feature of European fisheries management is a programme to reduce the level of capacity in EU fisheries. A criticism of such programmes is that the remaining fleet can increase their level of fishing effort thereby reducing the benefits from the programme. The extent to which the remaining fleet is capable of increasing effort is partly dependent upon the current level of efficiency of t...
In order to anticipate failures and reduce downtime, “predictive diagnostic” aims not only at warning about the failure events before they occur but also at identifying the causes of degradation leading to such detections. Then, based on the results of predictive diagnostic, “prognostic” aims at estimating the remaining useful life in order to plan a maintenance action before unit performances ...
Fleet management addresses the problem of managing fleets of trailers, containers, boxcars, taxicabs, locomotives and business jets. In many applications, requests to be moved from one location to another arrive randomly over time. Since it may take days to move from one location to the next, it is often useful (even necessary) to reposition equipment before a customer demand is known. We use t...
Fleet automation often involves solving several strongly correlated sub-problems, including task allocation, motion planning, and coordination. Solutions need to account for very specific, domaindependent constraints. In addition, several aspects of the overall fleet management problem become known only online. We propose a method for solving the fleet-management problem grounded on a heuristic...
