Purpose Due to mitigate against natural disasters like earthquake and distribute relief items, designing humanitarian chain networks is an attentional issue. Agile efficient distribution of items after occurring a disaster significant, especially when some the are perishable. Therefore, purpose this paper create resilient integrated decision-making structure at demand points, considering two dimensions sustainability, under disruption. Design/methodology/approach This study developed mixed-integer nonlinear mathematical model handle pre- post-disaster planning occurs. The represented has objective functions: minimizing weighted unmet total costs. convert multi-objective problem into single one, e-constraint method was applied. Findings main results showed that resilience strategies significant effect in reducing amount saves More precisely, 60% reduction 11% pre-positioning On other hand, maximum response time with applying another achievement present study. For these reasons, use can reduce people’s pain suffer from disasters. In general, application effectiveness sustainability introduced network were analyzed. Practical implications To verify applicability study, applied on probable real-life case Tehran. Finally, managerial insights discussed help organizations, managers stakeholders make better decisions negative effects Originality/value two-stage stochastic for disruption, stages. Also, economic social considered Moreover, assembling perishable im-perishable as kits, dynamically contribution research.

Natural disasters are accidental and unpredictable occurrences requiring particular procedure developments to minimise their impairment. Adequate capacity with appropriate location of medical centres, effective distribution reliefs, auxiliary equipment play an influential role in post-disaster relief rescue operations. Pre-disaster efforts can be practical not only for Humanitarian Supply Chains (HSCs) but also supportive Organizations (HOs) the phase. This study presents a two-stage stochastic programming model which (1) site numeral Temporary Medical Centers (TMCs) given number existing hospitals, probability damage roads/hospitals besides categorising casualties (triage) analyzed, (2) influence Quantity Flexibility (QF) contract is investigated pre-positioning procurement planning. After selecting reliable supplier(s), determines suitable level ordering each item. Also, identifies optimal TMCs positioning solution considering casualty types, demand, span between affected regions, centres available capacity, multi-transportation modes. A case conducted earthquake-prone area Tehran. Extensive sensitivity analyses accomplished gain valuable managerial insights. The results prove proposed trade off strategic, tactical, operational decisions pre-and-post-disaster phases.
