With the establishment of these relative units which cover the fields of social science, healthcare and education, a service delivery process of the whole early intervention has been formed to provide relative services to children with developmental delay and their families.
In fact, many multi-tier applications are often executed across multiple VMs [9] (e.g., front-end, business logic and back-end tiers of e-commerce services, or clustered MapReduce computing environments) and the relative services are available to the end-user only when all VMs in the group are active and connected to each other.
Increasing numbers of tourists, relative service infrastructures, such as, shops, restaurants, and hotels, and in addition, insufficient management measures, result in the decline of water quality.
Phase 4: Aggregation of relative service weights.
Phase 3: Computation of relative service performances.
Specifically, four different scenarios are considered: (S1) low mobility with small relative service time, (S2) low mobility with large relative service time, (S3) high mobility with small relative service time, and (S4) high mobility with large relative service time.
Table 6 Parameters for the considered scenarios Scenario Description Mobility parameter (η/μ(S)) Relative service time (μ(P /μ(S)) S1 Low mobility, small relative service time 0.2 0.1S22 Low mobility, large relative service time 0.2 1 S3 High mobility, small relative service time 1 0.1 S4 High mobility, large relative service time 1 1.
Selection can also occur based on a score, taking into account the relative service weight calculated during service ranking.
Second, increasing the relative service time implies that the mean value of the secondary service time relative to the mean value of the primary service time increases.
Similarly, Fig. 8 shows that the critical operational point decreases as either relative service time or mobility parameter increases.
This proposed service ranking method involves the following four phases that have been thoroughly discussed in [19]: Phase 1: Expressing ranking problem into a hierarchical structure Phase 2: Computation of relative quality of service (QoS) attribute weights Phase 3: Computation of relative service performances Phase 4: Aggregation of relative service weights.
