TL;DR: The aim of this survey paper is to classify and review the literature on heterogeneous vehicle routing problems, and presents a comparative analysis of the metaheuristic algorithms that have been proposed for these problems.

TL;DR: This paper presents a formulation that allows transshipments, either from the supplier to customers or between customers, and proposes an adaptive large neighborhood search heuristic to solve the Inventory-Routing Problem with Transshipment.

TL;DR: A mixed integer programming formulation for the VRPCD, where a set of homogeneous vehicles are used to transport orders from the suppliers to the corresponding customers via a cross-dock, using a tabu search heuristic embedded within an adaptive memory procedure to solve the problem.
Abstract: Over the past decade, cross-docking has emerged as an important material handling technology in transportation. A variation of the well-known Vehicle Routing Problem (VRP), the VRP with Cross-Docking (VRPCD) arises in a number of logistics planning contexts. This paper addresses the VRPCD, where a set of homogeneous vehicles are used to transport orders from the suppliers to the corresponding customers via a cross-dock. The orders can be consolidated at the cross-dock but cannot be stored for very long because the cross-dock does not have long-term inventory-holding capabilities. The objective of the VRPCD is to minimize the total travel time while respecting time window constraints at the nodes and a time horizon for the whole transportation operation. In this paper, a mixed integer programming formulation for the VRPCD is proposed. A tabu search heuristic is embedded within an adaptive memory procedure to solve the problem. The proposed algorithm is implemented and tested on data sets provided by the Danish consultancy Transvision, and involving up to 200 pairs of nodes. Experimental results show that this algorithm can produce high-quality solutions (less than 5% away from optimal solution values) within very short computational time.

TL;DR: In this paper, the spectral properties of the distance matrix of a connected graph and its spectral properties were investigated and the authors reported the results related to the distance matrices of a graph and their spectral properties.
Abstract: In 1971, Graham and Pollack established a relationship between the number of negative eigenvalues of the distance matrix and the addressing problem in data communication systems. They also proved that the determinant of the distance matrix of a tree is a function of the number of vertices only. Since then several mathematicians were interested in studying the spectral properties of the distance matrix of a connected graph. Computing the distance characteristic polynomial and its coefficients was the first research subject of interest. Thereafter, the eigenvalues attracted much more attention. In the present paper, we report on the results related to the distance matrix of a graph and its spectral properties.

TL;DR: In this paper, the authors examine the interests and values of various organizational actors in three collaborative initiatives, focusing on the mobilization of power within the governance frameworks available to them, and elaborate on three alternate readings of the processes examined: the managerialist views poor interorganizational collaboration as a failure to adequately manage the process; the symbolic focuses on the value of collaborative initiatives even in the absence of instrumental results; and the third examines the systemic web of power relationships reproduced over time.
Abstract: This article explores the challenges of mandated collaboration among public health care organizations. This in-depth longitudinal multiple case study examines the interests and values of various organizational actors in three collaborative initiatives, focusing on the mobilization of power within the governance frameworks available to them. The authors elaborate on three alternate readings of the processes examined: The managerialist views poor interorganizational collaboration as a failure to adequately manage the process; the symbolic focuses on the value of collaborative initiatives even in the absence of instrumental results; and the third examines the systemic web of power relationships reproduced over time.
