Engineering design is a process in which a system's parameters are selected such that the system meets certain criteria. These criteria vary in nature and may involve such matters as structural strength, implementation cost, architectural considerations, etc. When random variables are part of a system model, an added criterion is usually the failure probability. In this paper, we examine the buffered failure probability as an attractive alternative to the failure probability in design optimization problems. The buffered failure probability is more conservative and possesses properties that make it more convenient to compute and optimize. Since a failure event usually occurs with small probability in structural systems, Monte-Carlo sampling methods require large sample sizes for high accuracy estimates of failure and buffered failure probabilities. We examine importance sampling techniques for efficient evaluation of buffered failure probabilities, and illustrate their use in structural design of two multi-story frames subject to ground motion. We formulate a problem of design optimization as a cost minimization problem subject to buffered failure probability constraints. The problem is solved using importance sampling and a nonlinear optimization algorithm.
A novel numerical method based on an idea of orthogonal approximation of functions, namely Block Pulse Functions, is proposed in this work. Thus, we exploit and rigorously develop this direct approach based on the blo...

The properties of the fluids will be calculated through a nonlinear optimization (polynomial fit) that allows the generation of a pvt synthetic own of the area from laboratory data. A synthetic PVT was realized establishing a range of applicability through of correlations, correlation coefficients and graphs 1 to 1, fitting all the properties with an excellent correlation coefficient. The goal of the synthetic PVT was obtaining correlations to integrate the information of the area and represent the properties of the fluids taking the laboratory information. Later it will be defined the impact that the properties of the synthetic PVT could generate in the prediction of production, oil original on site and decide what PVT to use in the reservoirs of the field. This PVT will be used in areas without representative PVT. It is important indicates that the structural elements limit the reservoirs. Copyright 2018, Society of Petroleum Engineers.
