Stochastic bilevel programming in structural optimization
نویسندگان
چکیده
The present paper serves to introduce a new robust modelling technique and solution methodology for a class of problems in structural optimization, in which we calculate the structural design that responds the best on average to a given set of loads, each having its own probability of occurrence. A very general stochastic model is presented, along with its mathematical properties, generalizing some recently published results. A heuristic and an exact algorithm for solving the program are presented, along with an e ective parallelization strategy. Numerical experiments are provided.

BILEVEL LINEAR PROGRAMMING WITH FUZZY PARAMETERS
Bilevel linear programming is a decision making problem with a two-level decentralized organization. The textquotedblleft leadertextquotedblright~ is in the upper level and the textquotedblleft followertextquotedblright, in the lower. Making a decision at one level affects that at the other one. In this paper, bilevel linear programming with inexact parameters has been studied and a method is...
متن کاملEffects of Probability Function on the Performance of Stochastic Programming
Stochastic programming is a valuable optimization tool where used when some or all of the design parameters of an optimization problem are defined by stochastic variables rather than by deterministic quantities. Depending on the nature of equations involved in the problem, a stochastic optimization problem is called a stochastic linear or nonlinear programming problem. In this paper,a stochasti...
متن کاملOptimistic Stackelberg solutions to bilevel linear programming with fuzzy random variable coefficients
In this paper, we consider a kind of bilevel linear programming problem where the coefficients of both objective functions are fuzzy random variables. The purpose of this paper is to develop a computational method for obtaining optimistic Stackelberg solutions to such a problem. Based on a level sets of fuzzy random variables, we first transform the fuzzy random bilevel programming problem into...
متن کاملA Multi-objective Transmission Expansion Planning Strategy: A Bilevel Programming Method
This paper describes a methodology for transmission expansion planning (TEP) within a deregulated electricity market. Two objective functions including investment cost (IC) and congestion cost (CC) are considered. The proposed model forms a bi-level optimization problem in which upper level problem represents an independent system operator (ISO) making its decisions on investment while in the l...
متن کاملContinuous Optimization On generalized semi-infinite optimization and bilevel optimization
The paper studies the connections and differences between bilevel problems (BL) and generalized semi-infinite problems (GSIP). Under natural assumptions (GSIP) can be seen as a special case of a (BL). We consider the so-called reduction approach for (BL) and (GSIP) leading to optimality conditions and Newton-type methods for solving the problems. We show by a structural analysis that for (GSIP)...
