WebOptimal Computing Budget Allocation (OCBA) for Efficient Simulation-based Decision Making Under Uncertainty -- Simulation Optimization by Professor Chun-Hung Chen This … 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).

WebWe consider a simulation-based ranking and selection (R&S) problem under a fixed budget setting. Existing budget allocation procedures focus either on asymptotic optimality or on one-step-ahead allocation efficiency. Neither of them depends on the fixed simulation budget, the ignorance of which could lead to an inefficient allocation, especially when the …
