  • Multi-objective Optimization for Equitable Post-Disaster Relief Supply Distribution

    Creator:
    Subramaniam, Purnima
    Abstract:
    Humanitarian logistics in the post-disaster phase of an earthquake requires detailed planning about the relief distribution network including assigning available distribution centers (DCs) to the affected areas, distribution of the relief commodities demanded by the affected population, and efficient allocation of the available vehicle fleet for the distribution in a...

  • Multi-objective Resilience Optimization of Interdependent Critical Infrastructure Networks

    Creator:
    Tiong, Achara
    Abstract:
    Critical Infrastructures (CIs) such as energy, water supply, telecommunications, and transportation are highly vulnerable to cascading failures due to their interdependent operations. A resilient network is crucial to withstand the impact of functionality loss in disruptive events. This research evaluates network expansion as a proactive resilience strategy in which new...

  • Operations Research Models for Blood Supply Chain Network Design for Disaster Planning

    Creator:
    Baik, Shefaa A.
    Abstract:
    A blood supply chain (BSC) deals with the collection, processing, storing, and distribution of blood collected from donors and delivered to patients at demand points (DPs) through a network of several temporary mobile blood units (MBUs) and permanent local blood centers (LBCs). In general, the strategic and tactical design of...

  • Reliable Integrated Planning: Applications in Hub Network Design and Airline Ground Crew Task Assignment

    Creator:
    Barahimi, Pouya
    Abstract:
    In general, making optimal decisions is a never ending challenge that decision makers face. A comprehensive model that integrates decisions at all three levels of decision making (i.e., strategic, tactical, and operational) can help the decision maker to find solutions that best serve the organization's performance. However, as organizations expand...

  • Incorporating Uncertainty in Truckload Relay Network Design

    Creator:
    Mokhtari, Zahra
    Abstract:
    In a relay network for full truckload (TL) transportation, facilities known as relay points (RPs) serve as exchange points where truck drivers can exchange trailers. This would help carriers to assign more regular tours to drivers when compared to the excessively long tours that exist in the traditional Point-to-Point (PtP)...

  • Evolutionary Approach for a Multi–Objective Spare Parts Location–Inventory Problem with Time–Based Service Levels

    Creator:
    Rajaraman, Prasanna Venkatesh
    Abstract:
    Facility location-allocation decisions and inventory stocking decisions are very important in spare parts logistics. Both sets of decisions affect total costs in the system and the service levels that can be achieved by establishing distances between customers and distribution centers (DCs) in facility location-allocation, and by determining the availability of...

  • Integrated Intermodal Logistics Network Design

    Creator:
    Ghane-Ezabadi, Mohammad
    Abstract:
    Intermodal freight transportation uses at least two different transportation modes (e.g., truck, rail, ship, air) to move freight loads that are in the same transportation unit (e.g., a shipping container) from origin to destination without handling the goods themselves. The increasing shift to intermodal transportation and the growth of freight...

  • Interaction of Design Factors in the Truckload Relay Network Design with Mixed Fleet Dispatching Problem

    Creator:
    Jenks, Christopher L.
    Abstract:
    Truckload carriers operating under a Point-To-Point (PtP) dispatching method seek to minimize miles driven with empty loads. This results in driving tours keeping drivers away from their homes for weeks at a time causing high turnover rates industry wide. One proposed solution combines Relay Network dispatching with existing PtP. This...

  • Sequencing using Surrogate Values on Paced Assembly Lines

    Creator:
    Alfaiz, Faisal S.
    Abstract:
    On a paced mixed-model assembly line various product variants are assembled in the same sequence of serially arranged workstations that make up the line. The goal is to assemble the products with the lowest cost possible while meeting demand requirements. Since the work content of product variants may differ at...
