  • Supply Planning for Shelters and Emergency Management Crews Operational Research

    Fragkos, M., Zeimpekis, V., Koutras, V., Minis, I.

    International Journal of Operational Research, 2020

    Received: 28 December 2019 / Revised: 28 February 2020 / Accepted: 3 March 2020 

    Abstract

    This paper addresses the problem of supplying provisions to civilians affected by an emergency and to the intervention groups that provide post emergency relief. We define the Emergency Supply using Heterogeneous Fleet Problem (ESHFP) using a Mixed Integer Linear Programming mathematical model that describes the complexities involved in these operations. Furthermore, we propose a novel heuristic algorithm which constructs a plan comprising a set of efficient vehicle routes in order to minimize the total supply time, respecting constraints concerning timing, demand, capacity and supply. The characteristics of the problem have been studied by solving an extensive set of test cases. The efficiency and practicality of the algorithm has been tested by applying it to a large scale ESHFP instance and to a case study involving a forest fire in the Province of Teruel, Spain.

  • A Strategic Model for Exact Supply Chain Network Design and its Application to a Global Manufacturer

    Arampantzi, Ch., Minis, I., Dikas, G.

    International Journal of Production Research, vol.57, no. 5, 2019, pp. 1371-1397

    Abstract

    This paper presents a comprehensive model that captures significant strategic decisions involved in designing or redesigning high-performance supply chains from the perspective of the manufacturer. The problem considers deterministic demand by multiple clients, for multiple products, over the periods of a long-term horizon. The design decisions involve selection of suppliers, establishment or resizing of production facilities and distribution centres, possible subcontracting of related activities, and selection of transportation modes and routes. The problem is formulated by a Mixed Integer Linear Programming model. Its objective is to minimise the overall costs associated with procurement, production, inventory, warehousing, and transportation over the design horizon. Appropriate constraints model the complex relationships among the links of the supply chain. The proposed model has been applied to a large case study of a global manufacturing firm, providing valuable insights into the transformation of the firm’s current supply chain network, as well as into the potential of the proposed approach.
