TL;DR: This work examines the choice between continuing or ending a full lockdown within a simple optimal control model that encompasses both health and economic outcomes, and pays particular attention to when need for care exceeds hospital capacity.
Book ChapterDOI
A population-based local search for solving a bi-objective vehicle routing problem
TL;DR: In this paper, a population-based local search algorithm was proposed for solving a bi-objective vehicle routing problem, where the objective is to minimize the tour length and balance the routes.

Optimal Control of a Class of Systems with Continuous Lags: Dynamic Programming Approach and Economic Interpretations
Richard F. Hartl,Suresh Sethi +1 more
TL;DR: A maximum principle is derived for dynamic systems with continuous lags, i.e., systems governed by integrodifferential equations, using dynamic programming and the adjoint variables can be provided with useful economic interpretations.
Journal ArticleDOI
Exact solutions for the collaborative pickup and delivery problem.
TL;DR: This study investigates the decision problem of a central authority in pickup and delivery carrier collaborations and shows that, while for the original problem Benders decomposition is the method of choice, for the newly formulated problem this method is clearly dominated by the proposed column generation approach.

Interaction of pricing, advertising and experience quality: A dynamic analysis
Jonathan P. Caulkins,Gustav Feichtinger,Gustav Feichtinger,Dieter Grass,Richard F. Hartl,Peter M. Kort,Peter M. Kort,Andrea Seidl,Andrea Seidl +8 more
TL;DR: The optimal mix of marketing instruments may lead to history-dependence and there may be a market failure such that a government subsidy could help reach the steady state that is best for the Economy in the sense of having greater sales and a higher quality product.
