**Begin** |

**Step 1:** Define test-sheet problem and determine test-sheet composition goal |

**Step 2:** Structure the hierarchy from the top through the intermediate levels (criteria on which |

* *subsequent levels depend) to the lowest level (Figure 1). |

**Step 3:** Construct a set of pair-wise comparison matrix *C* (size , here , shown in |

* *(Table 1). The pair-wise comparisons are done in terms of which element dominates |

* *the other. |

**Step 4:** Calculate the sorted weights. Calculate maximum eigenvalue and its eigenvector |

* * for comparison matrix *C* through , and then normalize to get the |

* *final weight vector *ω* (Table 2). |

**Step 5:** Test consistency |

**Step 5.1:** Calculate consistency index CI through |

**Step 5.2:** Find the average Random Index RI through Table 3. |

**Step 5.3:** Calculate consistency ratio CR through CR = CI/RI |

**Step 6:** If , the * *comparison matrix *C* is consistent and return; if , the |

* *comparison matrix *C* should be modified, and return Step 4. |
