Quasi-replicate factors do not directly contribute to your DOE design. They are factors used to generate the data required to calculate a response of interest.
Depending on your application, you may sometimes need to calculate a response from measurements taken for example, under different treatments, or at different time points, so that you can generate a time course and calculate a response from it. Therefore, every run in your design needs to be replicated once for each of the different treatments or time points. This is when you want to define a factor as a quasi-replicate, where each run from your DOE design will be replicated once for each of the levels of this factor.
