Different types and capacities of crawler hoes are being considered for use in a major excavation on a pipe-laying project. Several supervisors who served on similar projects in the past have identified some of the attributes and their view of relative importance. For the information that follows, determine the weighted rank order, using a 0-to-10 scale and the normalized weights.
Attribute Comment________________
1. Truck versus 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. Pipe laying speed ....... 80% as important as hoe cycle time
