Optimization Of Vehicle Routing And Scheduling With Travel Time Variability - Application In Winter Road Maintenance, Haifeng Yu
Dissertations
This study developed a mathematical model for optimizing vehicle routing and scheduling, which can be used to collect travel time information, and also to perform winter road maintenance operations (e.g., salting, plowing). The objective of this research was to minimize the total vehicle travel time to complete a given set of service tasks, subject to resource constraints (e.g., truck capacity, fleet size) and operational constraints (e.g., service time windows, service time limit).
The nature of the problem is to design vehicle routes and schedules to perform the required service on predetermined road segments, which can be interpreted as an arc …

Public Private Partnership In Transit Projects, Rashmita Daschaudhuri
Theses
The government is cutting down government impediments and entering into the market. One of the outcomes has been the rise of Public-Private Partnerships (PPPs). There have been a lot of information and transaction cost problems in government institutions. These issues can be sorted and mitigated if the risk is shared with the private sector.
Until 1990, there had been a monopoly of the public sector developing transit projects. Now with the PPP concept, the transit projects are slowly moving into public private partnership agreements. This study tries to identify the various approaches of public private partnership delivery system. A few …
