Abstract

Methods and systems for allocating representatives, such as clinical research associates (CRAs), to sites. One embodiment comprises a method for allocating CRAs to sites by determining for each CRA the first segment travel time from a starting location to a first node associated with a CRA, and the second segment travel time from the first node to a plurality of second nodes, wherein each second node is geographically associated with a site, determining the third segment travel time from each second hub to its corresponding site(s), for each CRA determining the aggregate travel time to each site by adding at least the first, second and third travel segments, for at least some of the CRAs and at least some of the sites, evaluating the aggregate travel times between CRAs to each of the sites, and allocating a CRA to allocate to each site based in part on the travel times.

9. The method of claim 6, wherein calculation of the second segment travel time from the first node to each of the second nodes is based on a different mode of transportation than calculation of the first segment travel time from the starting location to the first node.

10. The method of claim 6, further comprising:

adjusting determined travel times based at least in part on corresponding traffic conditions.

11. The method of claim 6, further comprising:

adjusting determined travel times based at least in part on corresponding weather conditions.

12. The method of claim 6, wherein allocating a representative to each of the sites further comprises:

determining the number of sites each representative is currently allocated to.
