Different types and capacities of crawler hoes are being considered for use in a significant excavation project to bury fiber-optic cable in Argentina. Several supervisors who have experience with similar projects have identified key attributes and their view of relative importance. Determine the weighted rank order (0 to 10 scale) and the normalized weights. Attribute Comment 1. Truck vs. hoe height 90% as important as trenching speed 2. Type of topsoil Only 10% of most important attribute 3. Type of subsoil 30% as important as trenching speed 4. Hoe cycle time Twice as important as type of subsoil 5. Hoe trenching speed Most important attribute 6. Cable-laying speed 80% as important as hoe cycle time
Different types and capacities of crawler hoes are
being considered for use in a significant excavation
project to bury fiber-optic cable in Argentina. Several
supervisors who have experience with similar
projects have identified key attributes and their view
of relative importance. Determine the weighted rank
order (0 to 10 scale) and the normalized weights.
Attribute Comment
1. Truck vs. hoe height 90% as important as trenching speed
2. Type of topsoil Only 10% of most important attribute
3. Type of subsoil 30% as important as trenching speed
4. Hoe cycle time Twice as important as type of subsoil
5. Hoe trenching speed Most important attribute
6. Cable-laying speed 80% as important as hoe cycle time
As Table 1 shows, there are total 6 observations (attributes). According to 0 to 10 scale, the 5th observation can give 10th rank since it is the most important one. 1st observation is 9th rank, since it is 90% important, 2nd observation is 1st rank since it is only 10% important, 3rd observation is 3rd rank since it is 30% important, 4th observation is 6th rank since it is twice of the 3rd rank (3*2), and finally the 6th observation is 4.8th rank since it is 80% as important as hoe cycle time (80% of 6).
