Efficient comparison of constrained systems using dormancy

Definition of efficiency indicator and study of its main function as an optimization criterion

“…Despite a large number of publications, for example [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]20] which are devoted to efficiency or optimization criteria development, indicators that are based on all objects of the full global operation model are practically absent.…”

“…Increase of business development's rates is closely connected with a possibility of the perceived and objective choice of the best way of a scenario among many possible alternatives [1][2][3]. A necessary condition of such development is value increase of operational process output products in relation to the input products value.…”

Selection Procedures for Simulations with Multiple Constraints under Independent and Correlated Sampling

“…This article is most closely related to the work of Andradóttir and Kim [2010] and Healey et al [2013]. Andradóttir and Kim [2010] introduced a fully sequential, IZ framework for constrained R&S consisting of two phases: feasibility check and selection of the best (comparison).…”

“…These phases may be addressed either sequentially (the feasibility of each system is determined before comparison begins) or simultaneously (the feasibility check and comparison screening occur simultaneously after each additional sample). Andradóttir and Kim [2010] and Healey et al [2013] proposed and analyzed several fully sequential IZ R&S procedures within this framework for independent systems with one constraint. For procedures that try to minimize switching due to the possibly high cost of stopping and restarting complex simulations, see Healey et al [2014].…”

S-model

“…Simultaneously running procedures can be further improved using the concept of dormancy (Healey et al 2013), whereby a system may become dormant -halting sampling for that system -when it is found inferior to another system whose feasibility has not been determined yet, returning to contention only if its superior system is eliminated. If the superior system is found to be feasible, then the dormant system will be eliminated.…”
