Embodiment Construction

[0030] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0031] The plant processing flow recommendation method based on singular value decomposition of the present invention comprises the following steps:

[0032] (1) Input a factory processing "reference process" and a process library containing n factory processing processes;

[0033] (2) Take an unprocessed factory process and transform it into a corresponding task-based process structure tree (Task-based process structure tree, TPST);

[0034] (3) Extract the m, n-gram set of TPST, where m and n are self-defined;

[0035] (4) Repeat steps (2) and (3) until all input processes are processed;

[0036] (5) Establish an association matrix R based on all factory processing processes in the process library, which specifically includes the following steps:

[0037] (5.1) Take the union of the m and n-gram sets of each factory processing process in th...

Abstract

The invention discloses a factory processing flow recommendation method based on singular value decomposition. The method comprises the steps of converting a factory processing flow 'reference flow 'which is being modeled and all factory processing flows in a flow library into corresponding process structure trees based on task nodes; extracting an m, n-gram set of the TPST corresponding to each processing flow in the flow library, wherein one m, n-gram represents a partial structure and behavior characteristics of one processing flow; taking a union set of the m, n-gram set of each factory processing flow in the flow library, and establishing an incidence matrix based on all the processing flows in the flow library; performing singular value decomposition on the incidence matrix, and dividing flows in the flow library into a plurality of classes according to a decomposition result; selecting any processing flow from each class of flow to be subjected to similarity calculation with the'reference flow', and using all the flows in the class of flow with the highest similarity as recommendation flows of the 'reference flow'. According to the invention, the most recommended flow of the 'reference process can be obtained only through one-time calculation, so that the calculation space is greatly reduced.

Description

technical field [0001] The invention relates to a factory processing flow recommendation method based on singular value decomposition. Background technique [0002] With the development of business process model management (Business Process Management, BPM) technology, more and more factories start to create their own process model library. For example, a hardware accessories factory has a large number of process models, including hardware accessories manufacturing, scheduling, quality inspection, workshop processing, process monitoring and other processes. The process models involved in a home appliance manufacturing factory include TV manufacturing process, refrigerator manufacturing process, air conditioner manufacturing process, electric fan manufacturing process, etc. These process models are important assets of the factory, and effective management can improve the efficiency and profit of the factory. As a process model management technology, process recommendation t...
