When portfolios require complex modeling for performance assessment, prohibitive computational processing times can result. Eliminating a small number of alternatives through an intelligent screening process can greatly reduce the number of alternative combinations, thereby decreasing a problem's evaluation time and cost. A methodology was developed for the class of hierarchical portfolio selection problems in which multiple objectives are all judged on the same sub-objectives. First, a novel capability-based alternative screening process was devised to identify and remove poor alternatives, thereby reducing the number of portfolios. Then, a performance-based portfolio screening process was explored to estimate portfolio sufficiency according to the performance requirements of the decision maker. Following the establishment of a set of sufficient portfolios, the analyst can employ higher resolution post-analysis methods to choose a final solution. Finally, the methodology was applied to a portfolio selection problem in which the United States Strategic Command attempts to select an ideal mix of intelligence, surveillance, and reconnaissance assets. After deconstructing the actual objective hierarchy, a set of representative alternatives were evaluated and a variety of screening procedures were applied to demonstrate significant reduction in the number of possible portfolios.\u003c\/p\u003e","brand":"Mia Karts","offers":[{"title":"Default Title","offer_id":51964318548256,"sku":"NEW1288306873","price":21.54,"currency_code":"USD","in_stock":false}],"url":"https:\/\/miakarts.com\/products\/screening-and-sufficiency-in-multiobjective-decision-problems-with-large-alternative-sets-1288306873","provider":"Miakarts Books","version":"1.0","type":"link"}
