Customer-Oriented Optimization in Public Transportation develops models, results and algorithms for optimizing public transportation from a customer-oriented point of view. The methods used are based on graph-theoretic approaches and integer programming. The specific topics are all motivated by real-world examples which occurred in practical projects. An appendix summarizes some of the basics of optimization needed to interpret the material in the book.
In detail, the topics the book covers in its three parts are as follows:
1. Stop location. Does it make sense to open new stations along existing bus or railway lines? If yes, in which locations? The problem is modeled as a continuous covering problem. To solve it the author develops a finite dominating set and shows that efficient methods are possible if the special structure of the covering matrix is used.
2. Delay management. Should a train wait for delayed feeder trains or should it depart in time? The author builds up two different integer programming models and a model based on project planning methods. Properties and solution methods are developed.
3. Tariff planning. Part 3 deals with the design of zone tariff systems, in which the fare is determined by the number of zones used by the passengers. The author presents a model for this problem and approaches based on clustering theory.
Researchers in developing countries often find that the particular country in which they work presents a range of unforeseen challenges. Indeed, their ability to carry out effective scholarship is often highly dependent on these factors. The great differences between working in countries as varied as India, China, Bolivia and Kenya can often come as a shock to the system. An ability to negotiate a bewildering array of cultural and logistical obstacles is therefore essential.
Overseas Research: A Practical Guide distils essential lessons learned by scores of students and scholars who have collected data and done fieldwork abroad. The authors fill the reader in on the many crucial pieces of advice: how to prepare for the field, how and where to find funding for onea (TM)s fieldwork, issues of personal safety and security, and myriad logistical and relational issues that often define onea (TM)s research experience abroad. As Barrett and Cason suggest, "Fieldwork is a sequence of decisions, some about the conduct of research, some about the conduct of life." The book focuses new field researchersa (TM) attention on that productive intersection, and includes many real-life accounts from experienced professionals whose own work abroad can inform those facing the field for the first time.
