Exact methods for the traveling salesman problem with multiple drones
Transportation Research Part C: Emerging Technologies, 2021 Drone delivery is drawing increasing attention in last-mile delivery. Effective solution methods to solve decision-making problems arising in drone delivery allow to run and assess drone delivery systems. In this paper, we focus on delivery systems with a single traditional vehicle and multiple drones working in tandem to fulfill customer requests.

Business Ethics, the Environment &Responsibility, EarlyView.ABSTRACT This study examines how individuals accept and navigate paradoxical tensions within a sustainability context, using a multiple case study of five Italian companies implementing circularity measurement tools. By exploring the interplay between self‐efficacy and acceptance of paradoxical tensions, drawing upon the Goal Setting and Paradox ...

Curator: The Museum Journal, EarlyView.ABSTRACT The paths taken by visitors in museums influence what they see, do, learn, and experience. Poorly designed museums can lead to missed goals and opportunities. In this article, I critically review visitor studies published since the 1930s to evaluate explanations for visitor path choice in museums, namely, the location and attractiveness of ...

Production routing decisions in a two‐echelon supply chain with multiple delivery modes
International Transactions in Operational Research, EarlyView.Abstract We study an original two‐echelon production routing problem with multiple delivery modes (2E‐PRP‐MDM). In the first echelon, the primary production facility is tasked with satisfying the demands of two distinct entities: a set of warehouses and a set of customers through direct shipments. In the second echelon, warehouses become delivery hubs,

A novel hybrid approach for solving the multiple traveling salesmen problem
Arab Journal of Basic and Applied Sciences, 2019 The multiple Travelling Salesmen Problem (mTSP) is one of the most popular and important operational research problems. It is a problem where n salesmen have to visit m cities such that each salesman has to visit at least one city and all the cities ...

A matheuristic for the traveling salesman problem with positional consistency constraints
International Transactions in Operational Research, EarlyView.Abstract We propose a matheuristic for the traveling salesman problem with positional consistency constraints, where we seek to generate a set of routes with minimum total cost, in which the nodes visited in more than one route (consistent nodes) must occupy the same relative position in all routes.

International Transactions in Operational Research, EarlyView.Abstract This paper investigates an extension of the vehicle routing problem in which, in addition to minimizing the distance traveled, the sequencing of customer visits is subject to precedence constraints that impose visiting priorities among customers.

Evaluation of drone system for thinning operations–a case study in Sweden
International Transactions in Operational Research, EarlyView.Abstract Thinning operations in forestry typically involve a two‐machine system (TMS) with a harvester and a forwarder. Its productivity in different forest conditions is well documented. To date, drones have been used for data collection and surveillance but not as an alternative to a TMS.
