摘　　要：This paper extends the stochastic frontier production theory to the case of multiple outputs and calculate the measurement of efficiency using the production theory. We further apply this method to construct the stochastic frontier production model with undesirable outputs. Finally, the model is used in an HIV immunology model and the efficient drug treatment strategies are then explored.All the models are estimated using the Maximum Likelihood Estimation method. Stochastic errors are considered in this model, which is an advantage over other deterministic efficiency models. Some of our conclusions agree with those published in related papers.This paper extends the stochastic frontier production theory to the case of multiple outputs and calculate the measurement of efficiency using the production theory.
