Pre-estimation medical consumable replenishment system and calculation method thereof

The invention provides a pre-estimation medical consumable replenishment system and a calculation method thereof. The system can build a dynamic sample database according to an input operation name, a name of a surgeon, variety of consumables and specifications of the consumables and calculates the consumable demand forecasting probability to obtain the replenishment quantity of the medical consumables corresponding to the variety and the specifications of the consumables based on optimized replenishment cost. Therefore, the system can conclude and summarize the demand law of related medical consumables according to the characteristics of various clinical operations and preferences of different surgeons and obtains the replenishment quantity of a certain medical consumable specifically, so that a zero-inventory management manner can be realized more efficiently in a hospital, the efficiency of capital can be developed more efficiently, the medical department cost is reduced, the space of a storeroom is saved, the flexibility and the convenience of management of the consumables are improved, and the pre-estimation medical consumable replenishment system has a great significance in standardization of the management process of the medical consumables of a medical department, accurate pricing, effective tracking and better risk avoidance.
