System, method and program product for scheduling interventions on allocated resources with minimized client impacts

A computer program product for applying interventions to allocated resources, said computer program product comprising a non-transitory computer usable medium having computer readable program code stored thereon, said computer readable program code causing one or more computers executing said code to:

• receive a change request requesting changes in a shared resource system;
• identify shared resource system elements (E) affected by implementing the requested change;
• determine individual impacts (I(L,E,T)) to elements in each shared resource system layer (L) at a given time (T) in a selected time frame ([TI,TF]);
• weight local impacts by layer, such that layer weights indicate the importance of layer impacts on final impact;
• determine an overall impact (I(E,T)) to client activity at said given time responsive to said weighted local impacts;
• return to determining individual impacts at a next given time (TI≤T≤TF) until said next given time is after said selected time frame;
• determine a time within said time frame having a minimum overall impact for implementing said requested change;
• and
• implement said requested change to said shared resource system at said determined time.
