Route optimization for maintaining road quality

Velotech Solutions (VTS) is a company specialised in detecting damages in public spaces, such as road damages, non-working light posts or crooked traffic signs. This detection happens by bike or by car, and covers every street in the city or neighbourhood. The routes for navigation are currently created by hand. In this thesis, a proposal is...

Time slot offering: the effect of various green labeling approaches on routing performance, considering customers' preferences: A case study at Crisp

A relatively new concept within demand management for time window assignment is green labeling; time windows which contribute to improving the routing performance in terms of sustainability. Certain time slots are given a so-called green label. From literature, limited information is known about the choice preference with regard to green...

Platform Development of BIM-Based Fire Safety Management System Considering the Construction Site

Fire at a construction site usually results in serious accidents. Therefore, fire management at the construction site is critical to decreasing possible accidents. However, conventional fire safety management can be problematic in many aspects, such as visualization, multi-stage alarm systems, and dynamic escape route optimization. To solve...

Initial Pipe Routing Optimization for Ship Conversion

In the volatile and demanding current market and in view of frequent implementation of new emission regulations, ship renovations entail more and more radical conversions of higher complexity. Application of optimization methods in the ship maintenance, repair, and conversion industry have been so far frequently overlooked, due to the former...

A novel method for joint optimization of the sailing route and speed considering multiple environmental factors for more energy efficient shipping

Energy saving and emission reduction have attracted a great deal of attention in the maritime industry. The optimization of a ship's energy efficiency can reduce energy consumption and CO₂ emissions effectively. However, most of the available studies only focus on either the sailing speed or route optimization, and the interaction...

A two-stage route optimization algorithm for light aircraft transport systems

This paper presents a route optimization algorithm for light aircraft operating under visual flight rules. The problem aims at finding a minimum-duration, collision-free route in three spatial dimensions with possible aircraft maneuvers. The optimal route takes into account the aircraft kinodynamic characteristics and its interaction with...

Free Route Airspace for Route Optimization

These thesis is the result of the study of the possibility of expansion of the two existing Free Route Airspaces (FRAs) in the portuguese airspace, creating a joint FRA, where the goal is to optimize the routes passing this airspace, making it more efficient and consequently more competitive. At a later stage, is also analyzed an union between...
