In September 1980, the Special Programme Panel on Systems Sciences of the North Atlantic Treaty Organization (NATO) sponsored an Advanced Research Institute (ARI) on "Systems Analysis in Urban Policy-Making and Planning" which was held at New College, Univer sity of Oxford, from 21st to 27th September. This week-long meeting brought together 35 invited delegates from most countries of the NATO Alliance to discuss the impact which syst~ms analysis has had and is likely to have on urban affairs. The manuscript was submitted to the publisher in June of 1982. Although the goal of the ARI was to assess the impact of urban systems analysis as seen through the eyes of those closely involved in such work, the meeting also addressed opportunities for future research and development, and therefore in this book we have attempted to synthesize discussions at the meeting with this in mind. But before we describe the structure of this book, it is worth recounting in a little more detail the intentions and organi zation of the meeting, for this has had an important effect on the type of papers produced here, the way they have been written, and the issues they address.

The idea of this book started at approximately 33.000 feet, somewhere above the Alps. On our way to a workshop in Venice we had the opportunity of appreciating the different types of landscapes and the complex patchwork of urban areas, agriculture, forests, rivers and lakes that can be seen from an aircraft. The complexity of this puzzle, and the complex task of managing its evolution, became the topic of conversation for the rest of the flight. It also became the topic of this book. Land-use management and multicriteria analysis offer countless opportunities for mutual reinforcement. These two fields have developed largely independently, but a trend towards the exploration of their synergies is now emerging. This is clear from the recent literature on land-use management, spatial analysis and spatial planning, which increasingly includes references to multicriteria methodologies and decision analysis. At the same time, a growing share of multicriteria applications now focus on environmental and land-use issues. This book includes contributions from authors coming from a variety of disciplines and backgrounds. All together they highlight current issues in multicriteria analysis and land-use management from theoretical, methodological and practical perspectives.
