Location design analysis of distribution centers for medical logistics aid of COVID-19 in West Java.

Considering costs is important to measure whether the distribution network design is efficient or not. When designing the logistics network, as a rule, the costs to be minimized are associated with facility operations and to transportation between facilities, or between facilities and users. This study then considers the costs to design the logistics network to improve the previous study. Facility location decision is made when the logistics system is started from scratch. Specifically, the location decision is often made when a new product or service is launched. The logistics network in this study is designed to distribute medical logistics aid of COVID-19 (Coronavirus Disease of 2019) in West Java. On March 11, 2020, WHO (World Health Organization) announced COVID-19 pandemic. A month later, April 13, 2020, President Joko Widodo officially announced COVID-19 as a national disaster. The location problem in this study belongs to single-echelon location problem. The method used in this study is optimal method by formulating the problem as an ILP (Integer Linier Programming) model. This study uses LINGO 12.0 to solve the model. This study has improved the previous study and it gives a different logistics network compared to the previous one. This study gives a more efficient total cost by 0.27% or Rp657,339/day. [ABSTRACT FROM AUTHOR]
