Sonlu durum otomatı kullanarak iş akış motoru tasarımı ve gerçekleştirimi

This study discusses the design and implementation of a software component that is called workflow. Workflow is a technology which is used by generally in large scale companies in industry for organizing and tracking different objects. The challenge, which we undertake in the study, designing a workflow engine to manage complex processing steps dynamically. The main issue is creating a dynamic system that is flexible enough to adapt to different businesses and different processes within the enterprises. The idea behind the workflow is like some of the models in computer science; graphs, finite state automata and petrinets etc. Finite state automata (FSA) used to model workflow. States of the FSA is representing the states of workflow and a standard workflow has start and stop states like FSA. Business process in industrial areas changes over time according to many factors. For this purpose, within the scope of the study, a rule engine integrated with the workflow engine was developed. The rule engine enables the workflow engine to adapt to changing business processes at runtime. The system was designed to automate the follow-up processes of the documents connected to the products in a technology products company. Documents are related to materials of the company and designed system integrated into the material management module of ERP system of the company. After go-live document request log data stored in custom tables. With using the data collected from document requests, were analysed using sequential pattern mining methods.
