Methods Of Variational Analysis In Pessimistic Bilevel Programming
<p>Bilevel programming problems are of growing interest both from theoretical and practical points of view. These models are used in various applications, such as economic planning, network design, and so on. The purpose of this dissertation is to study the pessimistic (or strong) version of …

Implementation and evaluation of nonlinear bilevel programming model of equilibrium network design problem
… investment decision making process using a bilevel nonlinear programming model of the continuous equilibrium network design problem. Toward this end, a descent type algorithm for solving the continuous equilibrium network design problem is proposed and the performance of the algorithm is …

The Productivity Trap in Kenya's Highland Agriculture: A Bilevel Programming Analysis of Credit and Wage Constraints
Much of the less developed world faces the problems of feeding an ever increasing population. Improved agricultural productivity is the key to improved food security and economic returns in these regions. Much of the necessary improvement in productivity is a function of improved factors of …

Effects of economic transition policies on Yugoslavia's agricultural sector: A quantitative approach
… performance (output) of the agricultural sector. Bilevel programming is used as the methodology because it recognizes different objectives of policy makers (government) at the upper-level, and state and private farms at the lower-level. The results of the research indicate that economic reasons …

Dynamic pricing with demand learning under competition
… We show that the problem can be formulated as a bilevel program in disequilibrium and as a Mathematical Program with Equilibrium Constraints (MPECs) in equilibrium. Using results from variational inequalities, bilevel programming and MPECs, we prove that learning the optimal strategies as well as …

Multidelity methods for multidisciplinary system design
… approach treats the system design problem as a bilevel programming problem and enables each subsystem to be designed concurrently. The second approach optimizes surrogate models of each discipline that are all constructed in parallel. Both multidisciplinary approaches use multifidelity …

Optimal Design and Analysis of Bio-inspired, Curvilinearly Stiffened Composite Flexible Wings
… for designing models used in the PAAW program. A bilevel programming (BLP) multidisciplinary design optimization (MDO) architecture is developed for the MDAO framework. The upper-level optimization problem entails minimization of weight, drag and ground roll distance, all subjected to both static …

Optimally Locating Facilities with Variable Characteristics
… the first one as a mixed-integer nonlinear programming problem and propose three methods for its solution: a Lagrangean heuristic, a branch-and-bound method with Lagrangean relaxation, and a branch-and-bound method with nonlinear programming relaxation. The computational results obtained on …
