Mining Resource Scheduling Protocols

Conformance checking and performance improvement in scheduled processes: A queueing-network perspective

“…The distribution of interarrival times A t and processing times per class B c can be fitted with the techniques presented in [16,21]. Service policies, P, can be discovered using the policy-mining techniques presented in [22], or assumed to be given, as in the case of discovering a F/J network from a schedule.…”

“…In earlier work, therefore, we argued for an explicit representation of the queueing perspective and demonstrated its value for several real-world processes [20,22]. However, the existing techniques all considered the simplistic setting of a singlestation system, whereas, this paper addressed the more complex scenario of service processes that are scheduled and have a multi-stage structure that involves resource synchronization.…”

“…Thus, A2 runs in O n 3 . It is worth noting that A2 may be easily adopted to dominate only a subset of the measures (T max , F max ) by disregarding the respective condition in lines [17][18][19][20][21][22]. This relaxation of the constraints would probably allow better performance on the ξ ∈ ΞC ξ measure.…”

Queue mining for delay prediction in multi-class service processes

“…In such a setting, the policy for handling customers is typically FCFS, within the same class. For derivation of more accurate routing policies, see [10]. These underlying assumptions reflect upon our choices of relevant predictors and parameter estimation techniques throughout the paper.…”

“…The experiments for the first call center correspond to the single-class scenario, since we have focused on a single type of customers. For the second call center, three customer types that represent the private sector are considered: VIP, Regular and Low priority (see [10] for further description of the dataset and the priority setting). The synthetic data that we later use for sensitivity analysis comes from a set of simulation runs, based on a multi-class service process.…”
