Redesigning Sample Transportation in Malawi Through Improved Data Sharing and Daily Route Optimization

Abstract: Problem definition: Healthcare systems in resource-limited settings rely on diagnostic networks in which medical samples (e.g., blood, sputum) and results need to be transported between geographically dispersed healthcare facilities and centralized laboratories. Academic/practical relevance: Existing sample transportation (ST) systems typically operate fixed schedules, which do not account for demand variability and lead to unnecessary transportation visits as well as delays. Methodology: We design an optimize… Show more

“…Some of the work on global health operations has extended traditional OM/OR topics into the context of global health, for example, inventory and procurement of health products (Gallien et al., 2017; Leung et al., 2016; Natarajan & Swaminathan, 2014, 2017); the optimization of supply chains, distribution, and logistics for diagnostic samples, medicine, and vaccines (De Boeck et al., 2022; Gibson et al., 2022; Jónasson et al., 2017; Noham et al., 2022; Parvin et al., 2018); and improving ambulance operations in developing countries (Boutilier & Chan, 2018; Gernert et al., 2022). Another stream of work has used predictive analytics to improve risk stratification (and consequently resource allocation) for healthcare delivery in resource‐limited settings (Boutilier et al., 2020, 2021).…”

“…Gibson et al. (2020) design an information‐sharing platform to collect demand data for diagnostic testing services, based on which they optimize the dynamic routing and scheduling of motorcycles in the sample transport system in sub‐Saharan Africa. Thus, it is worthwhile to investigate collaborative solutions for rural logistics based on resource and data sharing to improve land use, reduce empty vehicle miles, and accelerate deliveries.…”
