Single criteria optimization methods often fail to capture the complexity of problems faced by decision makers (DMs) in today's rapidly changing business environment. The mathematical foundation for multi- criteria decision making (MCDM) was developed over a century ago [Pareto, 1896]. Given the growing constituency of PC literate DMs in the business community, it is astonishing that the existing tools for MCDM are still too difficult to be used by non- mathematicians. Characteristic of a typical MCDM problem is the absence of a unique global optimum. Rather, multiple solutions to the problem often exist that are superior to (dominate) the others in the solution space. These solutions are known as Pareto optimal solutions.
