A multi-objective optimization model for logistic planning in the crisis response phase

Abstract

PurposeProper planning for the response phase of humanitarian relief can significantly prevent many financial and human losses. To this aim, a multi-objective optimization model is proposed in this paper that considers different types of injured people, different vehicles with determining capacities and multi-period logistic planning. This model can be updated based on new information about resources and newly identified injured people.Design/methodology/approachThe main objective function of the proposed model in this paper is minimizing the unsatisfied prioritized injured people in the network. Besides, the total transportation activities of different types of vehicles are considered as another objective function. Therefore, these objectives are optimized hierarchically in the proposed model using the Lexicographic method. This method finds the best value for the first objective function. Then, it tries to optimize transportation activities as the second objective function while maintaining the optimality of the first objective function.FindingsThe performances of the proposed model were analyzed in different cases and its robust approach for different problems was shown within the framework of a case study. Besides, the sensitivity analysis of results shows the logical behavior of the proposed model against various factors.Practical implicationsThe proposed methodology can be applied to find the best response plan for all crises.Originality/valueIn this paper, we have tried to use a multi-objective optimization model to guide and correct response programs to deal with the occurred crisis. This is important because it can help emergency managers to improve their plans.

Logistic planning for pharmaceutical supply chain using multi-objective optimization model

“…Health-care services and related logistics management play important roles in supply chain plans (Ershadi and Shemirani, 2019; Ershadi et al , 2020). The logistic models in the pharmaceutical supply chain are increased significantly in recent years due to their advantage (Wang and Jie, 2020; Ershadi and Shemirani, 2021). Many papers studied different mathematical models for presenting a new helpful solution.…”

The Association Between the Success of Information Systems and Crises Management (A Theoretical View and Proposed Framework)

“…Proactive Crisis Management: consists of actions that, if completed correctly and effectively, can prevent several crises from happening. It has two specific phases; namely, the signal detection phase and the preparation/prevention phase (A'dwan, 2019; Al Eid & Arnout, 2020;Ershadi & Shemirani, 2021;Hanna, Abdul Aziz, & Najib, 2018;Leta & Chan, 2021;Sofyan et al, 2021;West, 2020). The signal detection phase is the first phase where crisis-warning cues are recognized.…”

“…Crisis harm prevention aims to limit the damage from engulfing and spilling over into other unaffected divisions of the institution. It includes efforts to control the harm, not only material damage but also the distribution of information, because once the information is spread through the media, the harm could be amplified (A'dwan, 2019;Abdalbaqi, 2021;Al Eid & Arnout, 2020;Alpaslan & Mitroff, 2021;Berbekova et al, 2021;Dayour et al, 2020;Ershadi & Shemirani, 2021;Hanna et al, 2018;Kao et al, 2020;Leta & Chan, 2021;Ricke, 2020;Thielsch, Roseler, Kirsch, Lamers, & Hertel, 2020;Tokakis et al, 2019;Wut et al, 2021). The recovery phase, on the other hand, refers to restoring the status to normal business operations.…”

“…This activity includes improving and performing examined recovery mechanisms. The institutional objective is to return to regular performances by recovering the damages of physical and immaterial assets and rebuilding relationships within the institution and with the outside public (Al Eid & Arnout, 2020;Aldao et al, 2021;Alpaslan & Mitroff, 2021;Alteneiji et al, 2020;Berbekova et al, 2021;Dayour et al, 2020;Ershadi & Shemirani, 2021;Ferwanah, 2019;Le & Phi, 2021;Ricke, 2020;Sofyan et al, 2021;Sumukadas, 2021;Thielsch et al, 2020;Tokakis et al, 2019;West, 2020;Wut et al, 2021). Interactive crisis management involves the educational element, which is an examination of the other actions.…”

“…Crisis management involves interpreting and criticising to learn from it by constantly learning and reassessing to improve on what has been done previously. It further includes the evaluation of all previous steps with a view to reviewing and critiquing them to see what was done well and what was done poorly in order to better manage crises in the future (Abdalbaqi, 2021;Al Eid & Arnout, 2020;Alpaslan & Mitroff, 2021;Berbekova et al, 2021;Dayour et al, 2020;Ershadi & Shemirani, 2021;Ferwanah, 2019;Leta & Chan, 2021;Nizamidou & Vouzas, 2020;Ricke, 2020;Tokakis et al, 2019;Wut et al, 2021).…”
