Dynamic metamodelling in capacity planning

Abstract: Traditional capacity planning modelling techniques focus on the steady-state behaviour of a system. This is because transient behaviour complicates the problem, both conceptually and analytically, and solutions tend to be time consuming. Nevertheless, the transient behaviour of a system is often of equal consequence to that of the steady-state behaviour and requires methods for characterization. Further, today's increasingly powerful personal computers allow complex, dynamic behaviours to be modelled in a time… Show more

“…This is supported by Bertsimas and Sethuraman (2002) who state that the optimality loss for fluid relaxations decreases as the number of jobs in the system increases. This is also experienced by Stahlman and Cochran (1998) and Riaño et al (2006) where the latter get slightly better approximations when the utilization values are high. Furthermore, their approximations perform less well for decreasing input functions when the system starts to empty due to the problem of transition stated by Missbauer (2006b).…”

“…Odoni and Roth (1983) also derived approximations for the transient behaviour of the M/M/1 model for small t, where (1) is not a good approximation. Lin and Cochran (1990) and Stahlman and Cochran (1998) used similar formulations for modelling the transient behaviour of a work centre, Lin and Cochran (1990) also give approximations for the transient behaviour if ¶ > · for a limited period.…”

“…For example, the arrival rate of new jobs in a machine center may change or resources may become temporarily unavailable, see for example Lin and Cochran (1990) or Stahlman and Cochran (1998). Kolesar et al (1975) and Ingolfsson et al (2002) describe an approach for scheduling police patrol cars using the analysis of a non-stationary queueing system.…”
