Optimal Designs for Proportional Interference Models with Different Guarding Strategies

Interference models are commonly used in agriculture, industry, and other related fields. Optimal designs for these important topics block designs. In this work, we consider both direct total effects under guarded unguarded proportional interference models. Some general equivalence theorems established to characterize such efficient For models, generate optimal noncircular estimating effects, respectively. Particularly, remove the traditional circular assumption introduce which have less restriction and, more importantly, perform higher efficiency than existing also give construction of some model.
