Indifference Graphs and the Single Row Routing Problem

open access: yes, 1991
This thesis investigates the subclass of interval graphs known as indifference graphs. New optimal algorithms for recognition, center, diameter, maximum matching, Hamiltonian path and domination in indifference graphs are presented. The recognition algorithm produces a linear order with properties which allow the solution of the other problems in ...

Trade costs, infrastructure, and dynamics in a global economy

open access: yesInternational Journal of Economic Theory, EarlyView.
Abstract This study develops a dynamic two‐country model with trade costs linked to international infrastructure stock. With variable markups and firm heterogeneity, the welfare impact of trade costs depends on firms' cost distribution. Governments engage in a dynamic public investment game, leading to multiple steady states. The dynamic equilibrium of

Location of fueling stations and routing of zero‐emission well‐boats in the Norwegian aquaculture industry

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract We study the problem of locating hydrogen fueling stations for zero‐emission aquaculture vessels in Norway and model the problem as a location‐routing problem, considering both the location of hydrogen fueling stations and the routing of aquaculture vessels.

An iterated greedy‐based metaheuristic with local search for the rank pricing problem

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract The rank pricing problem involves determining optimal prices for a set of products while accounting for customers' budgets and preferences. This study develops an iterated greedy‐based metaheuristic to efficiently solve this problem. The core idea is to generate a sequence of solutions by iteratively applying destruction and reconstruction ...

Assessing inconsistencies in the FITradeoff method: a comparison of two preference modeling paradigms

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract Many decision‐making processes are susceptible to errors and inconsistencies introduced by decision‐makers (DMs). The development of decision support systems (DSS) has brought about a way to guide DMs through complex decision scenarios. However, due to the complexity of the process, inconsistencies may still arise.

Use of Cluster Analysis for Identifying Metafounders

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In the metafounder approach, the relationship matrix of metafounders, Γ$$ \boldsymbol{\Gamma} $$ is used to transfer information on relationships between pedigree founders into the numerator relationship matrix A$$ \mathbf{A} $$, creating matrix AΓ$$ {\mathbf{A}}^{\boldsymbol{\Gamma}} $$.

Serial Investing and Strategic Commitment in Markets With Unknown Competitors

open access: yesJournal of Economics &Management Strategy, EarlyView.
ABSTRACT We study how serial investors who regularly face unknown competitors attempt to make their projects dominant. Innovating in new markets often involves uncertainty over the nature of the final product and who the key competitors will be. Such projects also have long‐term funding needs, so a commitment to provide the necessary funds imparts a ...

Are CSR incidents truly bad news?

open access: yesJournal of Financial Research, EarlyView.
Abstract We revisit whether disclosures of negative Corporate Social Responsibility (CSR) incidents adversely affect firms' stock prices. While univariate tests reveal significant negative abnormal returns around incident announcements, the effect disappears once firm characteristics, industry, and time‐fixed effects are controlled for.

Linear Time Recognition of P4-Indifference Graphs

open access: yes, 1999
A graph is a P4-indifference graph if it admits an ordering < on its vertices such that every chordless path with vertices a, b, c, d and edges ab, bc, cd has ...
