of the latter constitutes a numerical simulation. 

 These are the so-called "Monte Carlo" simulations. 



The main shortcoming of the above procedure is that it 

 is laborious and does not yield the output statistics directly. 

 Whereas the input is a stochastic variable, the mechanical model 

 is deterministic. What is needed, then, is a mechanical model 

 which is stochastic, or, at the least, capable of handling 

 stochastic output directly. Such a model would be consistent 

 with the nature of the phenomena. 



It is believed that the procedure could easily be expanded 

 to include the cable-dynamics effects for restoration-force 

 dominated systems. At the same time, some simplifications might 

 be possible. 



CONCLUSIONS 



It is believed that the mooring dynamic model described 

 herein could be utilized for the analysis of moored-barge systems 

 of interest to the Navy. This may require some modification 

 and/or linkage with an existing cable-dynamics model. It is also 

 suggested that a stochastic model might be developed which would 

 be more consistent with the nature of the problem and potentially 

 very rewarding.
