Dear Enas

You don't elaborate what are these subcontractors for, and that is important. It is not de same to make the analysys for say building a high rise valued in 4 millon Euros than selecting subcontractors for an electric hydro dam project worths in excess 700 millon Euros

In any case I believe that nine criteria are not enough to evaluate subcontractors. There are many aspects that are not considered here and that are mportant

As an example, I use the following 18 criteria for selecting civil works main contractors and possibly the decision matrix is still incomplete; all depends on the type of projects

1. Maximize: Referrals from the construction industry

2. Maximize: Years in business

3. Maximize: Number of engineers

4. Maximize: Other technical specialties (Geologists, Architects, Hydro geologists, etc)

5. Maximize: Expertise on this type of project expressed as a number of projects executed

6. Maximize: Percentage of own equipment to be used in this project

7. Maximize: Number of projects finished in the last 15 years

8. Maximize: Amount in project value in hundreds of millions of Euros in the last 15 years

9. Maximize: Amount of working capital for this project in millions of Euros

10. Maximize: Number of own workers that will be in this project

11. Maximize: Square meters built in the last 3 years

12. Minimize: Average age of equipment to be utilized

13. Maximize: Number of projects delayed more than 10 % of initial schedule in the last 15 years

14. Minimize: Number of times taken to Court in the last 15 years

15. Maximize: Number of lawsuits won

16. Maximize: Liability insurance in millions of Euros

17. Minimize : Number of fatal labor accidents

18. Maximize: Quality (written statements from prior projects owners)

Dear Nolberto,

thank you so much for your answer, this factors are the top 10 criteria collected from the research out of 55 most important criteria

all factors you mentioned are already studied in the research and included

if you can make the comparison that will be great

best regards

Dear Enas

Sorry for my late answer. I had not seen yours.

Regarding your request, I am afraid that I don't understand it.

However, f you are requesting from me to make the pair-wise comparison between the criteria that I used, I am afraid that I can't do that. Simply, I don't work with AHP or ANP. I use other methods that don't need such arbitrary comparisons.

Even, if a do it, it would be useless because I don't know your problem, and even if a know it my comparison could differ from your own comparison, and this is one of my arguments against AHP and ANP.

Hi

the best way to gather the pair-wise comparisons is to draw your model in super Decision software and it automatically generate its questions
