Abstract
In order to improve the production and supply level of PC components and reduce the impact of risk accidents on production, this article hopes to solve the risk accident problems faced in industrial construction production by introducing mature constraint theories applied in the manufacturing industry. Firstly, this article introduces the widely used constraint theory and DBR method in traditional manufacturing industry; Secondly, based on the constraint theory DBR method, a pull production mechanism is established for the constraint buffering and material delivery of PC components, and risk accidents are defined and estimated; Then calculate and set buffer zones to reduce their risks and ensure the full utilization of bottleneck resources; The ultimate goal is to reduce production scheduling risks and improve production supply levels.
