Subject : 623 Military Science and Engineering
Keywords : Armed helicopter unit;Helicopter unit;Dynamic nature;Stochastic
Abstract : The paper attempts to model t tank versus tank battle scenario in which the defender is provided an armed helicopter unit support, against surprise advance of the attacker towards an important place. The stochastic and dynamic nature of the battle system has been handled by means of Monte Carlo simulation. In that activities like move, search, fire, hit and kill are simulated and their effect generated in the model. The game has been repeated for parameters relating to (i)fire power (ii) mobility (iii) intervisibility (iv) blind shooting (v) defender/attacker force ratio and (vi) helicopter unit support with the defender. Then, average numerical effect in each case have been analysed. Although the results are based on tentative data, the trend seems to suggest that a battalion of Centurion tanks or 2 coys with a helicopter unit support stand fairly good chance to defeat the attack by M-47/48 tanks equivalent to 4 coys. Neverthesituations and quantitatively assess weapon systems effectiveness under tactical alternatives and battle field environment. |

Subject : 623 Military Science and Engineering
Keywords : Maneuvers ;Tactics;Computer
Abstract : A computer simulation model of a tank Vs tank battle scenario was earlier developed and programmed on PRIME-750. The model has been refined and improved further in terms of organisation, terrain and tactics. The present paper describes the following features, which have been incorporated into the model: (a) units in formation (b) physical terrain features in the form of sand dunes (c) tactical maneuvers and (d) real-time graphic display of the whole combat action. In accordance with the scenario, improved criteria for maneuvers bypassing obstacles, search, and fire have been introduced. |

Subject : 623 Military Science and Engineering
Keywords : Finite population ;Bernoullian sequence
Abstract : Simulation experiments with the help of random numbers are increasing in various Defence application areas. Some authors have brought out autocorrelations in the sequences generated by the computer methods. To overcome this defect, a new algorithm based on the concept of random sampling (with replacement) from finite population has been developed. The constants in the linear congruential relation has been chosen so that (a) the proportion of distinct numbers in the generation compares with the theoretical expectation and (b) the period of the generator covers almost the entire population of 16-bit numbers. The criteria suggest to choose the variable multiplier (a/sub i/=2a/sub i-1/ +1) with initial value a/sub o/ = 2/sup 9/ +5 or 2/sup 10/ + 3. The randomness of the generation has been compared with that of a Bernoullian sequence. |
