MIRCE Mechanics is a scientific study of the laws of the motion of system functionability (ability of being functional) through time, to:

  1. Experimentally measure the trajectory of the motion of functionability through positive and negative functionability states, resulting from functionability events and tasks. Existing experimental and observational data clearly demonstrate that the motion of functionability through time of each individual system exhibits discrete and time dependent trajectory. Thus, a large number of similar systems deliver a large number of different discrete and time dependent trajectories. Consequently, the only way to determine the trajectory of the motion of system functionability is to apply statistical methods to calculate the average trajectory across all systems considered. Hence, the measures of system functionability like number of events, time in the states and similar are statistical variables.
  2. Scientifically understand the mechanisms of the motion, as statistical methods do not study the causes of statistical behaviour. Consequently, the systematic studies are applied to understand the:

    • Phenomena that cause occurrence of Functionability Events: such as: thermal ageing, actinic degradation, fatigue, pitting, acid reaction, bird strike, warping, abrasive wear, suncups formation on the blue ice runway, thermal buckling, photo-oxidation, production errors, strong wind, maintenance error, hail damage, lightening strike, hard landing, quality problems, sand storm and so forth;
    • Activities that lead to the completion of Functionability Tasks, such as: servicing, lubrication, visual inspection, repair, replacement, final repair, examination, partial restoration, trouble shooting, storage, modification, transportation, sparing, cannibalisation, refurbishment, health monitoring, restoration, packaging, diagnostics and similar.

    Scientific understating of mechanisms of the motion requires analysis within physical scale between 10-10 metre (atomic/molecular phenomena) and 10+10 metre (space and environmental phenomena).

  3. Mathematically define the laws of the motion of the functionability through positive and negative functionability states. It is necessary to establish expressions that will take the system through future time. This is achieved through the creation of MIRCE Mechanics Formulas, that probabilistically define the laws of occurrence of functionability events and tasks, which enable mathematical formulation of: expected functionability trajectory, number of functionability events, cumulative time in functionability states and similar measures as a time dependent characteristics.
  4. Compute the functionability trajectory and calculate functionability measures of new or existing systems. It could be beneficial to system engineers and programme managers to predict whether the system performance requirements will be delivered, with resources planned and constraints expected, through the life of a system. Thus, for each of feasible options of a system structure, manufacturing options, operational scenarios, maintenance policies and support strategies, a functionability trajectory can be predicted by making use the MIRCE Mechanics Formulas, at the time when technical, technological and management changes are possible at least time and cost.
