This paper describes an optimum design of stiffened plates using the object-oriented programming language SMALLTALK. Monte Carlo method is used to obtain an optimum value. The constraint conditions are related to the ultimate stress of panels, the collapse pressure of panels, the buckling stress of stiffeners, the buckling stress of a stiffened plate and the collapse pressure of a stiffened plate. The objective function is the volume of a stiffened plate. Example cases are demonstrated. The following remarks are obtained in the process of developing the program. (1) SMALLTALK makes it easy to revise or add a program because of its small programming unit, and to change the values of parameters and the search range of variables due to its interactive feature. (2) Monte Carlo method is not so efficient in search of an optimum value, but gives a satisfactory result in the stage of an initial design.
