The left-hand side is the distance and congestion associated with current facility choice j for a visit k, and the right-hand side is the distance and congestion at any location other than j. See Additional file 1 section 3 for more details.[http://www.medchemexpress.com/Velpatasvir.html Velpatasvir dose] Review of catchment modelsGravity models use the following general form to calculate an "attraction" measure for each patient i: ??Xm S j w d ij AG ???Xk ?? i j? Pi w d ij i? where Sj is the supply at provider j, Pi is the population at location i, w(dij) is the decay function based on distance of each patient-provider pair (i,j). The original 2SFCA method was introduced by Luo and Wang [7]; it allows the catchment [https://dx.doi.org/10.1089/jir.2011.0094 title= jir.2011.0094] of each provider and patient to float based on the distances between each pair.
