Interactive Multi Objective Programming as a Framework for Computer Aided Control System Design This monograph reports the development of an approach to computer aided control system design (CACSD). Of primary concern is the quality of cooperation between the designer and his computer. The designer is suggested to treat a CACSD problem as a search problem in which he and the computer cooperate to locate satisfactory designs among sets of candidates. Interactive Multi Objective Programming (IMOP) is employed to define the level of abstraction as well as the organization of the design facilities in the computer
