FUNDAMENTALS OF THE ANALYTIC NETWORK PROCESS - MULTIPLE NETWORKS WITH BENEFITS,COSTS,OPPORTUNITIES AND RISKS 总被引:2,自引:0,他引:2
Thomas L.SAATY 《系统科学与系统工程学报(英文版)》2004,13(3)
The general theory of the ANP enables one to deal with the benefits,opportunities,costs,andrisks(the BOCR merits)of a decision,by introducing the notion of negative priorites for C and Ralong with the rating(not comparison)of the top priority alternative synthesized for each of the fourmerits in terms of strategic criteria to enable one to combine the four B,O,C,and R values of eachalternative into a single outcome.Strategic criteria are very basic criteria individuals and groups useto assess whether they should make any of the many decisions they face in their daily operations.They do not depend on any particular decision for their priorities but are assessed in terms of the goalsand values of the individual or organization.Synthesis is made with two formulas,one multiplicativeand one additive subtractive that can give rise to negative overall priorities.This paper summarizesand illustrates basic complex decisions involving several control criteria under each of the BOCRmerits. 相似文献

Fundamentals of the analytic network process — multiple networks with benefits,costs, opportunities and risks 总被引:1,自引:0,他引:1
Thomas L. Saaty 《系统科学与系统工程学报(英文版)》2004,13(3):348-379
The general theory of the ANP enables one to deal with the benefits, opportunities, costs, and risks (the BOCR merits) of
a decision, by introducing the notion of negative priorities for C and R along with the rating (not comparison) of the top
priority alternative synthesized for each of the four merits in terms of strategic criteria to enable one to combine the four
B, O, C, and R values of each alternative into a single outcome. Strategic criteria are very basic criteria individuals and
groups use to assess whether they should make any of the many decisions they face in their daily operations. They do not depend
on any particular decision for their priorities but are assessed in terms of the goals and values of the individual or organization.
Synthesis is made with two formulas, one multiplicative and one additive subtractive that can give rise to negative overall
priorities. This paper summarizes and illustrates basic complex decisions involving several control criteria under each of
the BOCR merits.
Thomas L. Saaty holds the Chair of University Professor, Katz Graduate School of Business, University of Pittsburgh, Pittsburgh, PA, and
obtained his Ph.D. in mathematics from Yale University. Before that he was a professor at the Wharton School of the University
of Pennsylvania for ten years. Prior to that he spent seven years at the Arms Control and Disarmament Agency in the State
Department in Washington, DC, that carried out the arms reduction negotiations with the Soviets in Geneva. His current research
interests include decision-making, planning, conflict resolution and synthesis in the brain. As a result of his search for
an effective means to deal with weapons tradeoffs at the Disarmament Agency and, more generally, with decision-making and
resource allocation, Professor Saaty developed The Analytic Hierarchy Process (AHP) and its generalization to dependence and
feedback, the Analytic Network Process (ANP). He is co-developer of the software Expert Choice and of the software Super Decisions
for decisions with dependence and feedback. He has authored or co-authored twelve books on the AHP/ANP. Professor Saaty has
also written a number of other books that embrace a variety of topics, including Modern Nonlinear Equations, Nonlinear Mathematics, Graph Theory, The Four Color Problem, Behavioral Mathematics, Queuing Theory,
Optimization in Integers, Embracing the Future and The Brain: Unraveling the Mystery of How It Works. His most recent book is Creative Thinking, Problem Solving & Decision Making. The book is a rich collection of ideas, incorporating research by a growing body of researchers and practitioners, profiles
of creative people, projects and products, theory, philosophy, physics and metaphysics...all explained with a liberal dose
of humor. He has published more than 300 referred articles in a wide variety of professional journals. He has been on the
editorial boards of Mathematical Reviews, Operations Research, Naval Research Logistics Quarterly, Mathematical and Computer
Modeling, Socio-Economic Planning Sciences, Applied Mathematics Letters, and several others. He also served as consultant
to many corporations and government. 相似文献
