The state of linear optimization model complex biological medical facility as an example of combined pharmacological intramuscular injection. Criterion Optimization: side effects on liver cells(It was formed optimization criterion of the object and formalized problem of determining the optimum state of the object. It was further discussed solutions to the problem. Investigated the optimal response for solving the problem by changing the restrictions and accidental impact. Application developed using MatLab, which allows you to change all the parameters in real time and track changes as a result of the program.)
