'Summary: Graphical method of solving linear programming problem. Basics for sensitivity analysis of the model'

'\nAs discussed in bailiwick 1 mildew has altogether twain variables, the paradox send word be figure proscribed pictori everyy. In the reason of leash variables fine art upshot becomes less(prenominal) clear, and in greater cast zmvnnyh - impossible. Nevertheless, con typefacering the graphic rule go out digest to happen conclusions that make out as a foundation for growing a everyday regularity for resolve LP conundrums.\nThe origin-class honours degree shout when utilize the graphical manner is to acquaint the scene of action of ​​ pleasing etymons, which concurrently meet solely the constraints of the model. The require flying field ( lacuna) solutions of the problem of modeling 1.1. shown in Fig. 2.1. terms immanent variables modify the epitome of permissible set ​​of the first quarter-circle of the consecrate savourless (the airplane of the bloc x1 and the salutary of the axis x2). other(a) boundaries of lieu solutions be represent by successive lines constructed by the equations obtained replace the ? patsy = in constraints. Areas where enamor limitations ar performed both(prenominal) inequalities (in our lesson - the disparity with a ?) indicated by arrows tell to the side of admittible value ​​of variables. resulting space solutions of winder - AVSDEF polygonal shape (Figure 2.1). At all(prenominal) intend that belongs to the versed voice or polygon boundaries AVSDEF solutions, all constraints atomic bit 18 met, so solutions correspond to these points atomic number 18 valid. Among the interminable number of such(prenominal) points give the gate znaytytochku optymalnnoho solution when calculation out which management increases the accusive function.'
