BRIK, An Interactive, Goal Programming Model for Nuclear Exchange Problems
Abstract
VRIK, unique nuclear exchange model (NEM), is the first NEM to be both totally interactive and to rely entirely upon preemptive goal programming to drive its allocations. Written in Fortran 77 it exists on the VAX 11-798 using the UNIX operating system. Since it includes as internal allocation subroutine, it is completely transportable. BRIK will allocate weapons to targets in order to meet damage expectancy (DE) goals of the user. The decision variable is a non-integer geometric mean representing the number of weapons allocated to an entire target class, using any of 3 objective functions and up to 13 different allocation rules. The program is useful for a wide range of scenarios including meeting DE goals with the available arsenal or creating an arsenal to meet established goals. The programmed model uses a preemptive linear goal programming algorithm, allowing explicit preferential treatment of target classes, which can be placed into any of 7 priorities. Target values can be input to differentiate target classes within the same priority. BRIK computes single shot probability of survival using DIA's nuclear targeting vulnerability system or from vulnerability expressed as a PSI overpressure number. As currently dimensioned, the program can handle up to 20 target classes, 20 weapon classes, and 20 hedging constraints.
