Artificial Intelligence and the Management Science Practitioner: Links between Operations Research and Expert Systems

What are the similarities between management science/operations research (MS/OR) and expert systems (ES)? What are the differences between the two? How can ES help MS/OR and vice versa? Over the past year we have heard these questions asked many times. They remind us of the debates about decision support systems (DSS) and MS/OR in the late 1970s. By the early 1980s DSS had become mainstream MS/OR with its own departmental editor in Management Science.
