Application of Service Modular Design Based on a Fuzzy Design Structure Matrix: A Case Study from the Mining Industry

Table 10

Experts’ evaluations of the time correlation between service activities 8 and 9.

Expert	Fuzzy semantics	Triangular fuzzy number
1	Coal mining should not precede drivage.	(0, 0.1, 0.3)
2	Coal mining cannot precede drivage, but both of them circulate many times.	(0.8, 0.9, 1)
3	Coal mining should not precede drivage.	(0, 0.1, 0.3)
4	Coal mining cannot precede drivage, but both of them circulate many times.	(0.8, 0.9, 1)
5	Coal mining cannot precede drivage, but both of them circulate many times.	(0.8, 0.9, 1)
