Exercise 1 Scenario: A project management team in a construction company needs to select the best contractor for a new government building project. The selection criteria include Cost, Quality, Experience, and Time. 1. Construct the AHP Model o Identify the goal, criteria, and alternatives (three potential contractors: A, B, C). o Draw a hierarchical model that shows the goal at the top, followed by criteria and then alternatives. 2. How Many Pairwise Comparison Matrices Are Needed? o Determine how many matrices are required for pairwise comparisons of the criteria and for each alternative under each criterion. o List the matrices:  One matrix for criteria comparison.  Four matrices for alternatives comparison (one for each criterion). 3. List the Potential Conclusions (Ranked Contractors) o Based on the AHP calculations, determine which contractor is the most suitable for the project. o Rank contractors A, B, and C in order of suitability based on their overall scores.

Understand the Problem

The question is asking about how to apply the Analytical Hierarchy Process (AHP) for selecting a contractor for a construction project. It involves constructing a hierarchical model for decision-making, determining the number of pairwise comparison matrices needed for evaluating selection criteria and alternatives, and ranking the contractors based on calculations drawn from these comparisons.

Answer

Four pairwise comparison matrices; rank contractors A, B, C based on AHP scores.

For the given scenario using the Analytic Hierarchy Process (AHP): 1. Four pairwise comparison matrices are needed: one for comparing the four criteria (Cost, Quality, Experience, Time) and three for comparing each of the three contractors (A, B, C) under each criterion. 2. Potential conclusions involve ranking contractors A, B, and C based on their scores from the AHP calculations to determine their suitability for the project.

For the given scenario using the Analytic Hierarchy Process (AHP): 1. Four pairwise comparison matrices are needed: one for comparing the four criteria (Cost, Quality, Experience, Time) and three for comparing each of the three contractors (A, B, C) under each criterion. 2. Potential conclusions involve ranking contractors A, B, and C based on their scores from the AHP calculations to determine their suitability for the project.

More Information

Using AHP involves structuring the decision problem into a hierarchy, conducting pairwise comparisons, and calculating weights for each element to determine a priority ranking.

Tips

A common mistake is not ensuring consistency in your pairwise comparisons, which could lead to inaccurate results in AHP.
