(3) Formulate linear constraints in term of the binary variables that are assigned for given units in the following logical conditions. a. Among three candidate reactors only one should be selected. b. Among two candidate processes for a chemical complex at most one process can be selected. If the absorber is selected, then the distillation column must be included. However, if the distillation column is selected, the absorber may or may not be included. (3) c.
