In the process of workshop production scheduling, many risk factors can affect the reliability of production. The factors influencing the production scheduling include time, quality, equipment failure and so on. The stability is critical in the flow shop, so the risk factors related to the production scheduling should be considered in the workshop production. Workshop scheduling is taken as the research object in this paper. Along with the rapid development of database technology, the process of workshop production scheduling also involves the record and statistics of many historical production data. So data analysis technology will be used to analyze the risk factors in the process of workshop scheduling firstly inthis paper. Secondly, the simulation model for production scheduling integrated with the risk factors will be built. The aim of the model is to balance the flow shop plan and improve the production efficiency. Finally, an example is given to show that the risk factors selected in this paper and the model are effective for solving the risk problem of workshop production scheduling.
