An apparatus for prognosticating system performance in a spacecraft electrical system influenced by planned human activities, said spacecraft electrical system having a state vector and a telemetry subsystem, the apparatus comprising:

• a processor coupled to said telemetry subsystem and configured to acquire data relating to said state vector from said telemetry subsystem;
• memory coupled to said processor having stored therein mission plan data, said mission plan data comprising at least one plannable element relating to said planned human activities, said at least one plannable element comprising a value having a type and an interval of applicability;
• a spacecraft electrical system simulation core stored in said memory and executable on said processor to form a spacecraft electrical system simulation incorporating said mission plan data and said state vector data;
• a mission planning graphical user interface (GUI) executable to receive mission plan data, said mission planning graphical user interface (GUI) displaying results related to the spacecraft electrical system simulation;
• and
• a simulation monitor configured to receive data produced by said spacecraft electrical system simulation core and operable to produce data indicative of problematic behavior of said spacecraft electrical system simulation core, wherein said data indicative of problematic behavior comprises plan deviation responses.

A method for prognosticating system performance in a dynamic system influenced by planned human activities using a simulation having an executable simulation core and simulation variables, the method comprising the steps of:

• parsing data relating to said planned human activities into mission data having a plurality of plannable elements;
• autocoding each plannable element of said plurality of plannable elements into an executable plannable element;
• and
• coupling each said executable plannable element to said executable simulation core;
• coupling a telemetry subsystem to said simulation core and extracting a state vector of said dynamic system from said telemetry subsystem, said state vector having elements;
• identifying a planning conflict comprising identifying a difference between a value of an element of an initial state vector of said dynamic system and an initial value of a simulation variable representing said element;
• and
• displaying said planning conflict and at least one plan deviation response.

A computer readable media on which is recorded executable instructions for prognosticating system performance for a dynamic system influenced by planned human activities expressed as mission plan data, the dynamic system having a state vector and a telemetry subsystem, the executable instructions when executed by a processor performing the steps comprising:
