This invention concerns filling vacancies. It may be applied to finding replacements during staff shortages, or to filling entire rosters. It may also be used to fill casually occurring service needs, such as the need-for a child minding placement. The invention involves entering availability details into a candidate data store, and entering vacancy details into a vacancy data store. Automatic cross-matching of each vacancy to availability details create a list of available candidates for each vacancy. Automatically ordering the list for each vacancy ranks the candidates according to predetermined criteria. The vacancies are then filled with the top ranking available candidate. This may be performed automatically or involve the transmission of invitations and acceptances. The invitations may be automatically dispatched, and the responses may automatically update the data. It may be layered to integrate the filling of a vacancy with the provision of a service for a related period of time. For instance, integrating the filling of a teaching or nursing staff vacancy with the provision of child minding services for the same period.

Disclosed are methods for establishing the compatibility between two blood types on the basis of cross-matching (under a designated rule of stringency) the minor blood group genotypes of recipient and prospective donors. To determine compatibility, the blood group genotypes are mapped to corresponding phenotypes according to the expression states associated with a set of underlying haplotypes, and compatibility is established by establishing the compatibility of blood types constructed as a combination of constituent phenotypes. The bit strings are matched, preferably using an algorithm expression. Where ambiguity in mapping genotypes to haplotypes exists, it can be reduced based on frequency of occurrence of the haplotypes in the sample population, or resolved by gametic phasing. Such reduction or resolution of ambiguity is particularly desirable where mismatches in the antigens expressed by the constituent haplotypes have greater clinical significance.
