Abstract

Sağlık sektöründe ecza ürünlerinin üreticiden son tüketiciye ivedi bir şekilde temin edilmesi son derece önemlidir. Sektörün tedarik ağının karmaşık yapıda olması, ecza ürünlerinin dağıtımı çalışmalarına araştırmacıların ilgisinin artmasını sağlamıştır. Çalışmada ecza ürünlerinin dağıtımını içeren tedarik ağında, farklı yapılardaki talep noktaları için ecza deposu yeri seçim problemi ele alınmıştır. Bu bağlamda problem, kapasiteli tesis yeri seçim problemi olarak ele alınmış ve probleme yönelik yeni bir matematiksel model önerilmiştir. Hazırlanan model için uygulama bölgesi olarak İstanbul/Silivri ilçesi seçilmiştir. Çalışmanın devamında önerilen matematiksel model kullanılarak minimum mesafeyle dağıtım yapılması için açılması gereken ecza depolarının yerleri belirlenmiştir. Modelin sonuçlarını analiz etmek ve doğruluğunu göstermek amacıyla problemde kullanılan parametre değerleri değiştirilerek duyarlılık analizi yapılmıştır. Sonuçlar duyarlılık analizi ile birlikte sunulmuştur.

Pharmaceutical warehouse site selection problem considering the demands of medical ınstitutions and pharmacies

Abstract

It is extremely important that pharmaceutical products are effectively supplied from the producer to the end consumer in the health sector, The complexity of the supply network of the sector has increased the interest of researchers in the distribution of pharmaceutical products. In this study, site selection problem for pharmaceutical warehouse for the demand points of different structures is discussed in the supply network, which includes the distribution of pharmaceutical products, In this context, the problem is considered as the capacited site selection problem and a novel mathematical model is proposed for the problem. İstanbul / Silivri district is chosen as the application area for the proposed mode. After, the sites of the pharmaceutical warehouses that should be opened in order to distribute with minimum distance were determined using the proposed mathematical model. Sensitivity analysis is performed by changing the parameter values used in the problem in order to analyze the results of the model and to demonstrate its accuracy. The results are presented with sensitivity analysis.
