Webprobability, a larger portion of the computing budget should be allocated to those designs that are critical in the process of identifying the best design. On the other hand, limited … WebOct 18, 2024 · In this study, improvement of the allocation rule from the original OCBA procedure was proposed. The new improved rule is called elite group optimal budget allocation (EGOCBA). The concept of EGOCBA is the avoidance of allocating extra sampling to the local optimum in each iteration of the algorithm.

In computer science, optimal computing budget allocation (OCBA) is an approach to maximize the overall simulation efficiency for finding an optimal decision. It was introduced in the mid-1990s by Dr. Chun-Hung Chen. OCBA determines the number of replications or the simulation time that is needed in order to … See more OCBA's goal is to provide a systematic approach to run a large number of simulations including only the critical alternatives in order to select the best alternative. In other words, … See more Experts in the field explain that in some problems it is important to not only know the best alternative among a sample, but the top 5, 10, or even 50, because the decision maker may have other concerns that may affect the decision which are not modeled in the … See more Similar to the previous section, there are many situations with multiple performance measures. If the multiple performance measures are … See more The original OCBA maximizes the probability of correct selection (PCS) of the best design. In practice, another important measure is the expected opportunity cost (EOC), … See more The main objective of OCBA is to maximize the probability of correct selection (PCS). PCS is subject to the sampling budget of a given stage of sampling τ. In this case See more Multi-objective Optimal Computing Budget Allocation (MOCBA) is the OCBA concept that applies to multi-objective problems. In a typical MOCBA, the PCS is defined as in which • See more The goal of this problem is to determine all the feasible designs from a finite set of design alternatives, where the feasible designs are defined as the designs with their performance measures satisfying specified control requirements (constraints).
