The number of experts who responded to the questionnaire sent to them reached 22 experts, 8 from Asia, 9 from Europe, and 5 from Africa. The study found that there are great variations in the size of the problems faced by supply chains in the continents and their countries, and the solutions differ from one continent to another and from one country to another with different capabilities and adherence to the instructions for closure and cultural awareness. Therefore, understanding the problem and the solutions to it contribute a lot to addressing logistics disorders during emergency crises.
