Organizational Learning from Cybersecurity Performance: Effects on Cybersecurity Investment Decisions
2023
AbstractIS literature has identified various economic, performance, and environmental factors affecting cybersecurity investment decisions. However, economic modeling approaches dominate, and research on cybersecurity performance as an antecedent to investments has taken a backseat. Neglecting the role of performance indicators ignores real-world concerns driving actual cybersecurity investment decision-making. We investigate two critical aspects of cybersecurity performance: breach costs and breach identification source, as antecedents to cybersecurity investment decisions. We use organizational learning to theorize how performance feedback from these two aspects of cybersecurity breaches …
Models and algorithms for berth allocation problems in port terminals
2017
Seaports play a key role in maritime commerce and the global market economy. Goods of different kinds are carried in specialized vessels whose handling requires ad hoc port facilities. Port terminals comprise the quays, infrastructures, and services dedicated to handling the inbound and outbound cargo carried on vessels. Increasing seaborne trade and ever-greater competition between port terminals to attract more traffic have prompted new studies aimed at improving their quality of service while reducing costs. Most terminals implement operational planning to achieve more efficient usage of resources, and this poses new combinatorial optimization problems which have attracted increasing att…
Algunos problemas de rutas por arcos
2014
En esta tesis se estudian tres problemas de rutas por arcos muy importantes tanto a nivel práctico como teórico. Se tratan del General de Rutas por Arcos en un grafo dirigido (Directed General Routing Problem, DGRP), su caso particular, el problema de la Grúa (Stacker Crane Problem, SCP) y el problema del Cartero Rural Generalizado en un grafo dirigido (Generalized Directed Rural Postman Problem, GDRPP). El primer problema estudiado es problema de la Grúa el cual se define en un grafo mixto G=(V,E,A), donde cada arista o arco, (i,j), tiene un coste asociado cij > 0, y tiene como objetivo hallar una ruta de coste mínimo que recorra al menos una vez cada arco del grafo. El problema General de…
Fundamentos de Optimización Matemática en Economía
1999
La optimización matemática es un área dentro de las matemáticas que se encarga de la elección de la mejor alternativa de entre las posibles para un problema formulado en términos matemáticos. Este área de las matemáticas es muy amplia, debido a la diversidad de situaciones que se pueden plantear y a las distintas maneras de enfocar la resolución del problema. El presente texto, en la medida que pretende ser una herramienta para el análisis económico, se centra en la programación no lineal y en los métodos analíticos de resolución de esos problemas. Por tanto, el objetivo es proporcionar al lector los conocimientos básicos y avanzados de optimización matemática que destacan por su aplicabili…
Assessing the profitability of investment projects using ordered fuzzy numbers
2019
Background: This article is motivated by the fact that most approaches to capital budgeting are deterministic. In reality, the capital budgeting problem is accompanied by the uncertainty and risk associated with dealing with imprecise data. Taking this uncertainty into account when performing analyses and calculations not only helps to better measure the profitability of investment projects, but also to expand the applicability of capital budgeting methods under real-life or uncertain conditions. The major contribution of this paper is the development of a novel approach to assessing the profitability of an investment project in the presence of uncertainty. Methods: We present a novel appro…
