Abstract

The invention discloses a system and a method for implementing sales forecasting in the catering industry. Acquisition and information mining are performed on external data such as online review platform data, geographic position information data, weather information, market information and the like and internal data such as pos data, store information, dish information, company market activity information and the like by adopting a crawler technology, an image recognition technology, a text analysis technology and a deep learning algorithm, a fused forecasting model is established, week-by-week dish sales data within future three months is given, and a future order plan is given in combination with dish BOM (Bill of Material), store inventory, total warehouse inventory, safety inventory MRP (Material Requirements Planning) and the like. Compared with other exiting forecasting method, the MAPE (Mean Absolute Percentage Error) can be improved from 30-40% to 10-15%.

Description

technical field [0001] The present invention relates to a sales forecasting system and method, in particular to a system and method for realizing sales forecasting in the catering industry, belonging to the fields of web crawler, image recognition, text analysis and deep learning. Background technique [0002] Crawler technology is a program of "automated web browsing", which automatically grabs the information needed by users on the World Wide Web according to certain rules. With the development of the Internet, the network has become the carrier of a large amount of information. Crawler technology has also become an important part of data collection and is the most basic step in big data analysis. [0003] Text analysis technology refers to the representation of text and the selection of feature items, which is a basic problem in text mining and information retrieval. It converts the unstructured original text into structured information that can be recognized and proces...
