A platform for research: civil engineering, architecture and urbanism
AbstractOptimization has the appeal of mathematical elegance and the possiblity of being of practical significance. This significance is examined for the problem of producing least-cost structures. For aircraft, this simplifies to the production of structures of least weight, whereas in civil engineering, the existing conditions for design and construction in the United States seldom produce an environment for the existence of least-cost structures. Optimization procedures are examined within these situations when the objective functions and constraints are deterministic and when they are uncertain. The uncertainty is expressed as amenable to both probabilistic and fuzzy set specifications. This transformation, from crisp optimization to the concept of satisficing of structures, is explored.
