Claim One:
1. A method for coordinating maintenance of components of an infrastructure, the method performed using a computer system comprising one or more programmed data processors, the method comprising: determining, by the one or more data processors, a current physical condition for each of a plurality of the infrastructure components, the current physical condition comprising a value indicating a current degree of deterioration of the corresponding infrastructure component; sorting, by the one or more data processors, the plurality of infrastructure components into a plurality of groups based at least in part on the current physical conditions of the plurality of infrastructure components, each of the groups comprising a subset of the plurality of infrastructure components for which the determined current physical conditions of the infrastructure components sorted into the subset are similar to one another according to one or more similarity criteria; by the one or more processors, associating a representative condition value with each of the groups, the representative condition values representative of the current physical conditions of the infrastructure components belonging to the respective groups; estimating, by the one or more data processors, for each of the groups, using a deterioration model, a time series of estimated future physical conditions for the infrastructure components of the group, based on the representative condition associated with the group, the estimated future physical conditions each comprising a value indicating an estimated degree of deterioration of the infrastructure components of the group at a corresponding one of a plurality of future times which constitute the time series; by the one or more data processors, performing an optimization to yield an optimized schedule of projects, each of the projects associated with one of the groups and comprising at least one of: replacing, upgrading and refurbishing the infrastructure components of the group wherein the optimization is based on the estimated time series of future physical conditions for the groups; and maintaining the infrastructure by at least one of: replacing, upgrading and refurbishing the infrastructure components of one of the groups according to the schedule of projects.
