Variable Neighborhood Search for the Pickup and Delivery Traveling Salesman Problem with LIFO Loading

Abstract: This paper addresses a variation of the traveling salesman problem with pickup and delivery in which loading and unloading operations have to be executed in a last-in-first-out (LIFO) order. We introduce three new local search operators for this problem, which are then embedded within a variable neighborhood search heuristic. We evaluate the performance of the heuristic on data adapted from TSPLIB instances.

Dynamic Games in the Economics and Management of Pollution

Abstract: The paper provides a survey of the literature which utilizes dynamic state-space games to formulate and analyze intertemporal, many decision-maker problems in the economics and management of pollution.

Escaping the Gift Economy

Abstract: Researchers have analyzed the dark side of the gift, but they have remained blind to what it implies about the market. Drawing on the experiences of a group of informants who participated in an ethnographical study of house moving in Montreal, Canada, this article provides significant evidence that the unattractiveness of the gift economy can incite people to turn to the market as an escape. It examines how people use the market to free themselves from the straitjacket of social expectations—from the sense of indebtedness and emotional oppression—which constrains them in their reciprocity relations inside the gift economy. The standard views of CCT researchers concerning the valorization of the gift economy are challenged, as well as the axiology that implicitly informs their research. As a result, it is necessary to discuss the inversion of this axiology.

Evaluating passenger robustness in a rail transit network

Abstract: The purpose of this paper is to provide passenger robustness measures for a rail transit network. A network is robust when it reacts well to disruptions on links or stations. In order to measure robustness, indexes relative to the overall travel time of a network when links fail are introduced for two different cases: without-bridging interruptions and with-bridging interruptions. In the first case, passengers either have to wait for the failure to be repaired or find an alternative route in the network, whereas in the second case a bus service between the affected stations is provided and only the failing link is disrupted. A computation of these indexes for the Madrid commuter system shows their applicability.
