This book deals with decision making in environments of significant data
un- certainty, with particular emphasis on operations and production
management applications. For such environments, we suggest the use of
the robustness ap- proach to decision making, which assumes inadequate
knowledge of the decision maker about the random state of nature and
develops a decision that hedges against the worst contingency that may
arise. The main motivating factors for a decision maker to use the
robustness approach are: - It does not ignore uncertainty and takes a
proactive step in response to the fact that forecasted values of
uncertain parameters will not occur in most environments; - It applies
to decisions of unique, non-repetitive nature, which are common in many
fast and dynamically changing environments; - It accounts for the risk
averse nature of decision makers; and - It recognizes that even though
decision environments are fraught with data uncertainties, decisions are
evaluated ex post with the realized data. For all of the above reasons,
robust decisions are dear to the heart of opera- tional decision makers.
This book takes a giant first step in presenting decision support tools
and solution methods for generating robust decisions in a variety of
interesting application environments. Robust Discrete Optimization is a
comprehensive mathematical programming framework for robust decision
making.
