This volume addresses water policy issues related to water resources research, ground water, water conservation, urban water systems, water resource planning, supply and demand interaction, principles and standards, and cost-benefit analysis, as well as general, institutional aspects of local, state, regional, and federal policies. The five contributors are scientists with expertise in water resources policy; their associations with Congress, the administration, state and local governments, private industry, and the academic community provide broad perspectives of their subject. The focus of their concerns is the Carter administration's Water Policy Initiatives submitted to Congress in June 1978.

During the past two decades, the consideration of mUltiple objectives in modeling and decision making has grown by leaps and bounds. The nineties in particular have seen the emphasis shift from the dominance of single-objective modeling and optimization toward an emphasis on multiple objectives. The proceedings of this Conference epitomize these evolutionary changes and contribute to the important role that the tield of multiple criteria decision making (MCDM) now plays in planning, design, operational, management, and policy decisions. Of special interest are the contributions of MCDM to manufacturing engineering. For example, it has recently been recognized that optimal, single-objective solutions have often been pursued at the expense of the much broader applicability of designs and solutions that satisfy multiple objectives. In particular, the theme (MCDM and Its Worldwide Role in Risk-Based Decision Making) of the XIVth International Conference on Multiple Criteria Decision Making (Charlottesville, Virginia, USA, June 8-12, 1998) represents the growing importance of risk-cost-benefit analysis in decision making and in engineering design and manufacturing. In such systems, minimizing the of rare and extreme events emerges as an essential objective that risk complements the minimization of the traditional expected value of risk, along with the objectives attached to cost and performance. These proceedings include forty-five papers that were presented at the Conference. A variety of techniques have been proposed for solving multiple criteria decision-making problems. The emphasis and style of the different techniques largely reflect the fields of expertise of their developers.

The Sixth International Multiple-Criteria Decision Making (MCDM) Conference is one of a biennial series that serve as a forum for exchange of the latest information and new developments in this rapidly growing field. Participants are carefully chosen from among scholars and practitioners so that widely ranging perspectives and disciplines are represented; this insures the dissemination of valuable new know ledge to those scholars, policy-makers and industrial analysts who will best utilize and share it, both in developed and in third-world countries. The Sixth Internaitona1 MCDM Conference was held from June 4 to 8, 1984, at Case Western Reserve University, Cleveland, Ohio. The Conference program reflects the evolution of the field from infancy through adolescence to maturity, as marked by the progression from single-objective modeling and optimization to multiple-objective deci sion making. Because the theoreticians, practitioners and students who attend these MCDM conferences necessarily have different needs and expectations, the program now offers fewer monologues and more panels, overview papers and tutorial sessions, focusing on case studies and other practical experiences."
