More and more enterprises have turned to production method of multiple products with low volume, this change causes the idea and method of enterprise production plan and control to face challenge which have never been faced before. Under the production environment of multiple products with low volume, how enterprise can carry out scientific and efficient production planning and control system becomes the current hot topic of studying and application in current operation field. This article selects one typical manufacturing enterprise of S company as the study objective and has taken detailed analysis and improvement study on its production planning and control system.Based on the collection, classification and analysis of the documents and data, this article firstly studies and diagnoses the production management status under the production method 0f multiple products with low volumes, analyzes its product and manufacturing process characteristics as well as the existed problems, then takes focus to analyze the status the production planning and control system in S company before identifying the existed problems in details.
