Second-Order Nondifferentiable Multiobjective Mixed Symmetric Dual Programs Over Cones
Springer Science and Business Media LLC - Tập 14 - Trang 103-123 - 2014
S. K. Gupta, D. Dangar, N. Kailey, S. Kumar
In this paper, a pair of second-order mixed symmetric nondifferentiable multiobjective dual programs over arbitrary cones where each of the objective functions contains a pair of support functions is considered. Further, weak, strong and converse duality theorems are established under the assumptions of second-order K- (F,ρ)-convexity. Moreover, we have illustrated a numerical example which is sec...... hiện toàn bộ
Efficiency Improvement Strategy Under Constant Sum of Inputs
Springer Science and Business Media LLC - Tập 13 - Trang 579-596 - 2014
Sanjeet Singh, Surya Sarathi Majumdar
In this paper, we have formulated Data Envelopment Analysis (DEA) models to reduce the inputs in an inefficient Decision Making Unit (DMU) when the specific inputs are under the constant sum constraint. We have also extended the models to reallocate the excess input without any reduction in efficiency of other DMUs. These DEA models and methods developed in this work will help decision makers in d...... hiện toàn bộ
Generalized Univex Functions in Nonsmooth Multiobjective Optimization
Springer Science and Business Media LLC - Tập 12 - Trang 393-406 - 2013
Pallavi Kharbanda, Divya Agarwal, Deepa Sinha
In this paper, we have considered a nonsmooth multiobjective optimization problem where the objective and constraint functions involved are directionally differentiable. A new class of generalized functions (d − ρ − η − θ)-type I univex is introduced which generalizes many earlier classes cited in literature. Based upon these generalized functions, we have derived weak, strong, converse and strict...... hiện toàn bộ
An Iterated Local Search for the Budget Constrained Generalized Maximal Covering Location Problem
Springer Science and Business Media LLC - Tập 13 - Trang 301-313 - 2013
Majid Salari
Capacitated covering models aim at covering the maximum amount of customers’ demand using a set of capacitated facilities. Based on the assumptions made in such models, there is a unique scenario to open a facility in which each facility has a pre-specified capacity and an operating budget. In this paper, we propose a generalization of the maximal covering location problem, in which facilities hav...... hiện toàn bộ

A New Search Procedure for the Two-dimensional Orthogonal Packing Problem
Springer Science and Business Media LLC - Tập 14 - Trang 343-361 - 2015
S. Grandcolas, C. Pinto
In this paper we propose a new exact procedure for the two-dimensional orthogonal packing problem, based on F. Clautiaux et al. approach (Clautiaux et al. Eur. J. Oper. Res. 183(3), 1196–1211, 2007). The principle consists in searching first the positions of the items on the horizontal axis, so as that, at each position, the sum of the heights of the items does not exceed the height of the bin. Ea...... hiện toàn bộ
Sufficiency and Duality for Nonsmooth Multiobjective Programming Problems Involving Generalized (Φ, ρ)-V-Type I Functions
Springer Science and Business Media LLC - Tập 14 - Trang 159-172 - 2014
Chunlei Yan, Baocheng Feng
In this paper, a class of nonsmooth multiobjective programming problems is considered. We introduce the new concepts of (Φ, ρ)-V-type I, (pseudo, quasi) (Φ, ρ)-V-type I and (quasi, pseudo) (Φ, ρ)-V-type I functions, in which the involved functions are locally Lipschitz. Based upon these generalized (Φ, ρ)-V-type I functions, the sufficient optimality conditions for weak efficiency, efficiency and ...... hiện toàn bộ
Sea SAR Images Analysis to Detect Oil Slicks in Algerian Coasts
Springer Science and Business Media LLC - Tập 13 - Trang 371-386 - 2014
Bahia Lounis, Aichouche Belhadj-Aissa
In this paper, we investigate the performance of partition features derived from histogram analysis to isolate dark spots which are candidates to be oil spills in SAR images. The first partition is carried out to obtain preliminary clusters of the pixels on the basis of their grey level intensities and threshold values deduced from the histogram. The detection process is achieved by a contextual p...... hiện toàn bộ
Single and Multi Camera Simultaneous Localization and Mapping Using the Extended Kalman Filter
Springer Science and Business Media LLC - Tập 13 - Trang 23-57 - 2013
Simone Ceriani, Daniele Marzorati, Matteo Matteucci, Domenico G. Sorrenti
Simultaneous Localization and Mapping (SLAM) has received quite a lot of attention in the last decades because of its relevance for many applications centered on a mobile observer, such as service robotics and intelligent transportation systems. This paper focuses on the use of recursive Bayesian filtering, as implemented by the Extendend Kalman Filter (EKF), to face the Visual SLAM problem, i.e.,...... hiện toàn bộ
Upgrading p-Median Problem on a Path
Springer Science and Business Media LLC - Tập 14 - Trang 145-157 - 2014
Ali Reza Sepasian, Freydoon Rahbarnia
Upgrading p-median problem is a problem of finding the best median of the given graph through modification of its parameters. The current paper develops a polynomial-time model to address this problem when the weights of vertices can be varying under a given budget. Moreover, in the case where the considering graph has a special structure, namely a path, a linear time algorithm will be proposed fo...... hiện toàn bộ
