pharmaceutical engineering projects, especially large pharmaceutical engineering projects, from project proposals to feasibility studies. From preliminary design to construction drawing design, many technical and economic problems are involved, which affect the level and quality of pharmaceutical engineering design. can be analyzed and evaluated through technical and economic analysis and preparation of project budgets. Correct and reliable pharmaceutical engineering design must be a perfect combination of advanced technology and economy. This chapter will explore how to do this from an economic perspective. This paper analyzes and evaluates the engineering project, and briefly introduces the compilation method of engineering calculation.
