A study on supply chain investment decision-making and coordination in the Big Data environment
Springer Science and Business Media LLC - Tập 270 - Trang 235-253 - 2017
Pan Liu, Shu-ping Yi
In the Big Data environment, aims of enterprises investing in Big Data are to gain Big Data information (BDI). To study the decision-making issues of BDI investment and its effects on supply chain coordination, a supply chain with one retailer and one manufacturer was chosen. Meanwhile, considering a company owned the internal BDI and the external BDI, the market demand function was revised and fo...... hiện toàn bộ
Sampling issues for optimization in radiotherapy
Springer Science and Business Media LLC - - 2006
Michael C. Ferris, Rikhardur Einarsson, Ziping Jiang, David Shepard
A wide variety of optimization problems and techniques are used in radiation treatment planning. The problems typically involve large amounts of data, derived from simulations of patient anatomy and the properties of the delivery device. We investigate a three phase approach for their solution based on sampling of the underlying data that determines optimal beam angles, wedge orientations and deli...... hiện toàn bộ
A new approach based on the surrogating method in the project time compression problems
Springer Science and Business Media LLC - Tập 143 - Trang 237-250 - 2006
Hadi Mohammadi Bidhandi
This paper develops a mathematical model for project time compression problems in CPM/PERT type networks. It is noted this formulation of the problem will be an adequate approximation for solving the time compression problem with any continuous and non-increasing time-cost curve. The kind of this model is Mixed Integer Linear Program (MILP) with zero-one variables, and the Benders' decomposition p...... hiện toàn bộ
An Oligopolistic Investment Model of the Finnish Electricity Market
Springer Science and Business Media LLC - - 2003
Pierre-Olivier Pineau, Pauli Murto
The investment problem faced by producers in deregulated electricity markets contains high uncertainties about the future. It can also be seen as a game, as only a small number of large players act in the market. A dynamic stochastic oligopoly model to describe the production and investment in such a situation is developed and applied to the Finnish electricity market. The demand growth rate is mo...... hiện toàn bộ
An analytical derivation of the efficient surface in portfolio selection with three criteria
Springer Science and Business Media LLC - Tập 251 Số 1 - Trang 161-177 - 2017
Qi, Yue, Steuer, Ralph E., Wimmer, Maximilian
In standard mean-variance bi-criterion portfolio selection, the efficient set is a frontier. While it is not yet standard for there to be additional criteria in portfolio selection, there has been a growing amount of discussion in the literature on the topic. However, should there be even one additional criterion, the efficient frontier becomes an efficient surface. Striving to parallel Merton’s s...... hiện toàn bộ
Short-term volatility timing: a cross-country study
Springer Science and Business Media LLC - - Trang 1-26 - 2022
Marta Vidal, Javier Vidal-García, Sabri Boubaker, Stelios Bekiros
In this paper, we examine how mutual fund managers behave to fluctuations in market volatility. We use a sample of daily return from countries around the world to evaluate how manager perform to publicly available information. There is a lack of empirical studies that examine the relation between conditional market returns and conditional volatility on a global scale; we provide evidence across co...... hiện toàn bộ
Some characterizations of resolute majority rules
Springer Science and Business Media LLC - - Trang 1-14 - 2023
Josep Freixas, Dani Samaniego
In this paper we consider decision functions in which voters have three options and one of them is abstention or indifference and the output is a binary decision between two alternatives so that a tie is not possible. These resolute decision functions appear frequently in grading, in some sport competitions, in voting situations in which the status quo is put to the vote, etc. It is a more restric...... hiện toàn bộ
Hedging against demand ambiguity in new product development: a two-stage distributionally robust approach
Springer Science and Business Media LLC - - Trang 1-35 - 2023
Yuanbo Li, Meiyan Lin, Houcai Shen, Lianmin Zhang
In the globalization era, many manufacturing companies face great uncertainties, as most components in new product development (NPD) are outsourced to external and internal suppliers worldwide. More seriously, component supply chain disruptions have been seen in the recent global outbreak of COVID-19. Hence, some key components must be reserved in advance to control risks considering the suppliers...... hiện toàn bộ
An optimization-based heuristic for the machine reassignment problem
Springer Science and Business Media LLC - Tập 242 - Trang 115-132 - 2015
Mehdi Mrad, Anis Gharbi, Mohamed Haouari, Mohamed Kharbeche
We address the machine reassignment problem proposed in the context of the ROADEF/EURO challenge 2012 in partnership with Google. The problem consists in reassigning a set of processes to a set of multiple-resource machines so as to minimize a weighted function of the machines load, the resources balance, and the costs of moving processes while satisfying numerous constraints. We propose an optimi...... hiện toàn bộ
Achieving growth in reliability
Springer Science and Business Media LLC - Tập 91 - Trang 11-24 - 1999
J. Ansell, L. Walls, J. Quigley
There exists a considerable literature on reliability growth modelling. Recently some common models have been extended to encompass innovation. They assume the time of an innovation is known and that there is a coincidental improvement in performance. However, despite such developments, it remains that most models do not fully address the engineering concerns as they do not capture the underlying ...... hiện toàn bộ
