The defects mentioned above, the author form an integrated first and second forms. Proposed improvements to form two-dimensional. Also, the model can also check the two indicators is the rate charged is reasonable and appropriate number of services equipment to minimize the total cost.
According to The defects Above, The author Integrated The Model Ⅰ and Model Ⅱ,. proposed an improved two-dimensional model. The model can also determine the two indicators which are the optimal service rate and the optimal number of mechanical services to minimize the total cost.
