The risks that can cause the biggest losses, should have the biggest importance weights. Itââ¬â¢s the same for criteria, each criterion has a relative importance weight comparing to other criteria. For finding each criterionââ¬â¢s importance weight (i.e. WC ) and each riskââ¬â¢s importance weight (i.e. WR), medical experts should compare each risk to all other risks and also each criterion to all other criteria using ANP method. The reason of using ANP technique in this framework is that, ANP enables us to consider all possible interrelationships among these criteria and risks. For further information on ANP approach please refer to Saaty et al. (Saaty Ãâ"zdemir, 2005). Now each of k risk and n criterion have weights, which indicates riskââ¬â¢s/criterionââ¬â¢s importance in comparison to others. The numbers inside parenthesis in PC and CR matrices are weights obtained using ANP methodology. In PC and CR matrices each criterion and each riskââ¬â¢s weight shouldShow MoreRelatedTest Case Prioritization for Black Box Testing in Component Based Systems12192 Words à |à 49 Pagesgreater testing time and higher cost. Using the test case prioritization technique, we can reduce the cost and time of testing. Most of the test case prioritization techniques proposed in previous works applies source code information as prioritization factors because those are based on OOT technology. In CB-system, it is proved difficult to apply those direct measurement factors for testing. Here, in this paper, I propose test case prioritization technique for component based system.

Prioritization based on other considerations has also been proposed for situations where the risk of death is low (Hadorn, 2000). In Dolan and Cooksonââ¬â¢s (Dolan Cookson, 2000) work the different principles of for priority-setting decision makings have been focused qualitatively (e.g. need, equity and fairness principles). However, quantitative approaches have yet to be developed.
