Determining pricing using categorized costs with tree structures

A computer program product for pricing a current contract for bid, the computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions executable by a hardware computer to cause the hardware computer to perform a hardware computer-implemented method comprising:

• generating, by a processor of the hardware computer, a tree of the current contract;
• generating, by the processor, trees of historical contracts according to a level of detail of the tree of the current contract to shorten resource consumption time to be commensurate with the level of detail of the tree of the current contract, the current contract and the historical contracts each specifying a respective plurality of services;
• grouping, by the processor, the trees of historical contracts to form a plurality of groups of trees, based on respective tree distances between the trees in each the plurality of groups of trees;
• identifying, by the processor, a group of trees, from the plurality of groups of trees, that is closest to the tree of the current contract by calculating respective distances there between;
• and
• calculating, by the processor, a price for the current contract based on gross profits and costs for each of the plurality of services in the identified group of trees,
• wherein said grouping, identifying, and calculating steps each use respective different methods to group, identify, and calculate, responsive to a service (a) having a baseline;
• and (b) lacking the baseline, wherein the baseline is a value that indicates a scale of the service.
