Abstract This study introduces the Interdependent Network Design Problem (INDP), concerned with defining minimum‐cost reconstruction strategy of a partially destroyed system infrastructure networks, subject to budget, resources, and operational constraints, while considering interdependencies between them. To solve INDP, authors develop an efficient Mixed Integer Programming (MIP) model, which considers different types interdependency exploiting efficiencies from joint restoration due...
The elementary shortest path problem with resource constraints (ESPPRC) is an NP-hard that often arises in the context of column generation for vehicle routing problems. We propose exact solution method relies on implicit enumeration a novel bounding scheme dramatically narrows search space. embedded our algorithm within to solve linear relaxation (root node) time windows (VRPTW) and found proposed performs well when compared against state-of-the-art algorithms ESPPRC well-known Solomon’s...
A central challenge in disaster risk management (DRM) is that there are key dependencies and uncertainty between the decisions made at mitigation, preparedness, response, recovery stages. Decision support systems for require information allow timely reliable integration of data sources from different domains, including on hazards vulnerabilities analysis, as well organizational logistical decision analysis. We propose an analytics-centered framework integrates predictive prescriptive models...
The vehicle routing problem with stochastic demands (VRPSD) consists of designing transportation routes minimal expected cost to satisfy a set customers random known probability distribution. This paper tackles generalization the VRPSD as multicompartment (MC-VRPSD), in which each customer several products that, because incompatibility constraints, must be loaded independent compartments. To solve problem, we propose three simple and effective constructive heuristics based on programming...
Road safety research in low- and middle-income countries is limited, even though ninety percent of global road traffic fatalities are concentrated these locations. In Colombia, injuries the second leading source mortality by external causes constitute a significant public health concern city Bogotá. Bogotá among top 10 most bike-friendly cities world. However, bicyclists one vulnerable road-users city. Therefore, assessing pattern understanding variables affecting outcome bicyclists'...
There is limited evidence on the gender differences and location-specific built-environment factors associated with bicycling in Latin American cities. This study aimed to assess commuting Bogotá by (1) analyzing gender-specific trend of standardized number bicycle commuters during 2005–2017; (2) assessing socio-demographic, community, natural stratified gender. secondary-data analysis included data from Household Travel Surveys Multipurpose calculate per habitant 2005 2017 We assessed...
The assessment of urban transport interventions is complex, multi-faceted, and context-dependent. This study proposes a multi-methodology approach called systems analytics to evaluate the potential impact implementation temporary bike paths during COVID-19 pandemic on Bogotá's bicycle complex system. proposed methodology applies theory identify complexity, barriers, facilitators system uses statistical simulation methods assess safety quality life users in Bogotá pandemic. results case...
