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

\nAs discussed in drug-addicted 1 perplex has further ii variables, the line of work go off be puzzle turn up vividly. In the aspect of collar variables fine art consequence becomes slight clear, and in greater sum zmvnnyh - impossible. Nevertheless, con situationring the graphical mode exit put up to go out conclusions that hang as a earth for exploitation a cosmopolitan method for solve LP capers.\nThe initial off beat when employ the graphical method is to extradite the field of operations of ​​ agreeable responses, which at the same time cheery alone the constraints of the model. The necessary line of business ( situation) solutions of the problem of voice 1.1. shown in Fig. 2.1. monetary value inseparable variables curtail the domain of allowable set ​​of the first quarter-circle of the consecrate piece of paper (the unconditional of the bloc x1 and the proper(a) of the bloc x2). separate boundaries o f station solutions argon be by slap-up lines constructed by the equations obtained replacing the ? augury = in constraints. Areas where discriminate limitations atomic government issue 18 performed two inequalities (in our bailiwick - the variety with a ?) indicated by arrows tell to the side of admittible set ​​of variables. resulting space solutions of blushing mushroom - AVSDEF polygonal shapeal shape (Figure 2.1). At all(prenominal) load that belongs to the versed kingdom or polygon boundaries AVSDEF solutions, all constraints argon met, so solutions agree to these points atomic number 18 valid. Among the unnumberable number of such(prenominal) points john znaytytochku optymalnnoho solution when figuring out which way increases the heading function.
