Silver Professor and Carma Chair in Operations Management Faculty of Management The University of Calgary Wednesday, 18 February 1998 Arts 209 1.00 p.m. Suggested Heuristic Approaches for Dealing with Probabilistic, Combinatorial Decision Problems. The mathematical representation of several important decision problems can be described as a combinatorial choice of values of decision variables in the presence of other probabilistic variables that affect the objective function and/or the constraints to be satisfied. The description implies a very difficult optimization problem. Some practical illustrations of such problems will be described. Then, two solution approaches will be presented. One is for the situation where it is practical to obtain the exact optimal solution given values of the probabilistic variables, while the other deals with the context where optimisation is not even guaranteed under such circumstances, thus necessitating some form of search procedure. Both approaches make use of statistical sampling to estimate the value of the objective function at any particular solution being investigated. Biographical Sketch: Dr Edward A Silver is a Professor and Carma Chair in Operations Management at The University of Calgary. He has a Science Doctorate in Operations Research from MIT, and following 4 years with the international management consulting firm, Arthur D. Little Inc., spent 12 years as a faculty member at the University of Waterloo. He has consulted and provided executive training for numerous organisations on topics including inventory management, business process improvement, production planning, and the use of quantitative modelling to aid in decision making. He has had over 120 articles published in professional journals. He is the past president of the Canadian Operational Research Society and the International Society for Inventory Research. -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
