“…An et al (2015) propose a reliable hub-andspoke network through the creation of hub backups and alternative flow routes. Similarly, Rostami et al (2018) ensure resilience through the assignment of backup hubs. However, as compared with this paper, both Rostami and An et al solve an assignment problem vs a network flow.…”

PurposeSupply chains need to balance competing objectives; in addition to efficiency, supply chains need to be resilient to adversarial and environmental interference and robust to uncertainties in long-term demand. Significant research has been conducted designing efficient supply chains and recent research has focused on resilient supply chain design. However, the integration of resilient and robust supply chain design is less well studied. The purpose of the paper is to include resilience and robustness into supply chain design.Design/methodology/approachThe paper develops a method to include resilience and robustness into supply chain design. Using the region of West Africa, which is plagued with persisting logistical issues, the authors develop a regional risk assessment framework and then apply categorical risk to the countries of West Africa using publicly available data. A scenario reduction technique is used to focus on the highest risk scenarios for the model to be tractable. Next, the authors develop a mathematical model leveraging this framework to design a resilient supply network that minimizes cost while ensuring the network functions following a disruption. Finally, the authors examine the network's robustness to demand uncertainty via several plausible emergency scenarios.FindingsThe authors provide optimal sets of transshipment hubs with varying counts from 5 through 15 hubs. The authors determine there is no feasible solution that uses only five transshipment hubs. The authors' findings reinforce those seven transshipment hubs – the solution currently employed in West Africa – is the cheapest architecture to achieve resilience and robustness. Additionally, for each set of feasibility transshipment hubs, the authors provide connections between hubs and demand spokes.Originality/valueWhile, at the time of this research, three other manuscripts incorporated both resilience and robustness of the authors' research unique solved the problem as a network flow instead of as a set covering problem. Additionally, the authors establish a novel risk framework to guide the required amount of redundancy, and finally the out research proposes a scenario reduction heuristic to allow tractable exploration of 512 possible demand scenarios.

“…They demonstrated that regionalizing a supply chain is an effective way to reduce the negative impacts of environmental disruptions. The design of hub transportation networks is a strategic issue that has been explored by Rostami et al (2018). Their model was designed for largescale problems based on the branch and bound framework of the Benders Decomposition technique.…”

In this paper, two policies are considered for supporting periodical publications by the government: direct subsidy payment to these publications and opening new facilities which could help with integration and reduce delivery costs. For this aim, a mixed-integer linear mathematical model is presented that minimizes total costs while considering social welfare. The robust programming approach developed by Bertsimas and Sim is used to cope with uncertain parameters. In order to validate the model and investigate its applicability and advantages, the magazines' subscriptions in Tehran is selected as a case study. The output of the model demonstrates that when social welfare is not considered, the risk-averted supply chain will focus on low-cost areas of the chain, which are the central areas of Tehran. However, when minimum social welfare is assured, the supply chain pays attention to all areas. Also, the government should increase supply capacity by opening new facilities, and it should differentiate between areas when paying direct subsidies..

Hub facilities may fail to operate in networks because of accidental failures such as natural disasters. In this paper, a quadratic model was presented for a reliable single allocation hub network under massive random failure of hub facilities which more than one hub may be disrupted in a route. It determines the location of hub facilities and the primal allocation of non-hub nodes. It also determines the backup allocation in case of failure of the primal hub. A lexicographic form of bi-objective quadratic model is developed where the first objective (maximization of served demand or equivalently, minimization of lost flows) must be attained before the second objective (total cost). By adding a structure-based constraint and using enhanced linearization techniques the model was converted into a classic linear zero-one mixed integer model. The applied linear technique was compared with other techniques in terms of computational time and its better performance was approved in problem instances. An iterated local search algorithm was developed to solve large sized instances in reasonable computational time and the compu-
