Sosyal sürdürülebilirlik kapsamında aşı soğuk zincir ağ tasarımı için matematiksel model önerisi

Aşıların tabii olduğu soğuk zincirde meydana gelebilecek kırılmalar; ciddi ekonomik, çevresel ve sosyal maliyetlerin yanında insan ve halk sağlığı açısından da önemli risklere neden olmaktadır. Bu nedenle etkili, sağlam ve güçlü bir aşı soğuk zincir ağının tasarlanması gerekmektedir. Diğer yandan, “Sağlıklı Bireyler” başlıklı Sürdürülebilir Kalkınma Hedefi 3, çocukların sağlığına vurgu yapmakta ve beş yaş altı ölüm oranlarının düşürülmesini hedeflemektedir. Bu çalışmada, Türkiye'deki Genişletilmiş Bağışıklama Programı EPI aşı tedarik zinciri ele alınarak Sürdürülebilir Kalkınma Hedefi 3 ışığında çok ürünlü, çok dönemli, çok aşamalı bir aşı soğuk zincir ağı için doğrusal programlama modeli geliştirilmiştir. Çalışma, beş yaşa kadar tam bağışıklanmış çocuk sayısını en üst düzeye çıkarmayı ve aşı soğuk zincir ağ tasarımı için bir çerçeve önermeyi amaçlamaktadır. Önerilen model vaka çalışmasına uygulanmıştır. Son olarak, çeşitli senaryo analizleri ile model sonuçları değerlendirilmiştir.

A mathematical model for vaccine cold chain network design considering social sustainability

Breakages that may occur in the cold chain cause serious economic, environmental, and social costs, as well as a substantial risk for human and public health. Therefore, it is necessary to design an effective, robust, and strong vaccine cold chain network. Sustainable Development Goal 3 titled “Good Health and Well Being” emphasizes children's health and specifies reducing the mortality rate for under five ages. In this study, we consider the Expanded Programme on Immunization (EPI) vaccine cold chain in Türkiye and develop a linear programming model for a multi-product, multi-period, multi-stage vaccine cold chain network in light of Sustainable Development Goal 3. The study aims to maximize fully immunized children for up to five years and propose a framework for a vaccine cold chain network design. The proposed model is applied to a real case. Finally, various scenario analyzes are applied to show the results of the model under different conditions.
