The yield of a chemical process depends on the length of time T (in minutes) that the process is run and the temperature TEMP (in degrees centigrade) at which the process is operated. This dependence is described by the equation where T’= (T- 90)/10 and TEMP’=(TEMP-150)/5. T must be between 60 and 120 minutes, while TEMP must be between 100 and 200 degrees. Insert the T’ and TEMP’ to the equation. Then solve a and b. a. Set up an NLP that could be used to maximize the yield of the process. b. Use GAMS to solve your NLP.
