Tripartite Evolutionary Game Analysis of Trust Relationship between Enterprises in a Cloud Manufacturing Environment: A Service Composition Perspective

Table 2

Perceived benefits matrix of the evolutionary game between the service demander, service provider, and platform supervisor.

Platform supervisor strategy		Supervision (z)		Nonsupervision (1 − z)
Service demander strategy		Trust (x)	Distrust (1 − x)	Trust (x)	Distrust (1 − x)
Service provider strategy	Trustworthy (y)	G1 + aαR3 + R2 − C1	0	G1 + aαR3 + R2 − C1	0
		G2 + (1 − a)R3 − R2 − C2	−C2	G2 + (1 − a)R3 − R2 − C2	−C2
		R1 − C	−C	bR1	0
	Untrustworthy (1 − y)	qαR4 + R2 − C4 − K − W	−C4	qαR4 + R2 − C4 − K	−C4

¹The first to third rows in the revenue perception matrix are provider, demander, and platform revenue, respectively. It should be noted that no transaction will occur when the demander chooses not to trust, but some participants have also paid the cost, so it must be included.
