Embodiment Construction

[0036] The method will be described in detail below in conjunction with the drawings and embodiments.

[0037] Step 1. According to the importance of the industrial process definition, the response speed requirements and the industrial process application data (including process name, process context, process application time and completion time, process definition size), determine the industrial process in formula 1 through formula 2 Apply probability p and Z for the industrial process size normalization auxiliary parameter in Equation 3,

[0038] Step 2. According to step 1, set the upper and lower limits of Z of the auxiliary parameter of industrial process size standardization, and determine the industrial process size standardization by formula 4 According to the relationship between the industrial process data and the process in step 1, the industrial process characteristic correction coefficient α and the industrial process call prediction correction coefficient β in f...

Abstract

The invention discloses a workflow engine cache elimination method based on an industrial process background. The importance, response speed requirements and industrial process application data are defined according to an industrial process, the industrial process application probability p and the industrial process size standardization auxiliary parameter Z in the final score are determined based on the industrial process applied probability calculated based on real data, the industrial process size standardization is determined, the final score S of each industrial process is calculated, and cache loading is carried out according to the number when the system is in cold start. A specific industrial process and a rapid final score sequence are searched, and which process definitions are loaded into a cache and eliminated from the cache is determined through a LinkedHashMap type variable. The cache insertion, updating, deleting and searching of the industrial process are rewritten in the Flowable workflow engine cache class. According to the method, the hit rate of the cache process definition can be improved, and the process with high importance and high time sensitivity in the industrial process is specially processed in algorithm, so that the process can quickly respond to server calling in a cache.

Description

technical field [0001] The invention belongs to the field of workflow engine and industrial process. The knowledge involved includes workflow specifications, workflow engine architecture, and cache elimination algorithms. Background technique [0002] As a workflow engine, a workflow can be built quickly, which makes the original process more standardized, the division of responsibilities is clearer, and the division of processes is more rigorous. However, the current workflow engines on the market mainly serve the Internet and financial fields, and cannot meet the following requirements for industrial applications: high response speed, high process complexity, diverse process relationships, and diverse process interaction objects. The default solution of the workflow engine is to cache the process definition to solve the problems of response speed, server resource saving and process definition being too large and complex. [0003] The process definition is unique to the w...
