Abstract:
1. A computer-implemented method for determining a best change schedule in response to a change request in an information technology system affecting two or more approvers in a change period, said approvers having change constraints, the method comprising: receiving, by a computer, a number of change requests, each of said change requests being associated with a list of approvers and a change due date; determining, by said computer, a set of candidate change schedules for each of a number of change periods on a basis of said change constraints, inputting, to said computer, preference values from said each approver for each of said candidate change schedules; determining, by said computer, which approvers of said list of approvers are affected by each of said change requests and retaining only those affected approvers to determine said set of candidate change schedules; weighting, by said computer, said preference values for each of said candidate change schedules by said weights for each said approver to obtain weighted preference values for each of said change periods; and ordering, by said computer, said set of candidate change schedules according to a sum of said weighted preference values to obtain said best change schedule for each of said change periods.
