Abstract: 
System evaluation is a process of determining the extent to which an evaluated system satisfies a set of requirements. The global degree of satisfaction is called the preference score, or simply the global preference. We evaluate complex systems using quantitative criteria based on the LSP method. In this presentation, we describe an efficient new method for generating optimum configurations. For systems having n inputs the time complexity of the proposed method is O(n). The new method eliminates the limitation of previous algorithms that were applicable only in the case of criteria having a binary tree structure. We will present the new Stepwise Filtering Method, and examples of its use.
