The safety instrumented system is a system that is independent of the
petrochemical production process control system and can independently
complete the safety interlock protection function. It can avoid significant
hazards to production equipment caused by process production failures,
field instrument failures, system power supply failures, etc., and ensure
safe operation of production equipment. In petrochemical plants, it is
imperative to configure a safe, reliable, and timely safety instrumented
system. Combined with applying the burner management system of the heating
furnace in a refinery, the paper focuses on the technical realization of the
hardware structure, system configuration, logic programming, man-machine
interface configuration system debugging of the TRICON system. Practical
application shows that TRICON?s safety instrumented system is a set of
safety instrumented systems with comprehensive functions, safety and
reliability, and easy to learn.
Abstract. The co-evolution mechanism of manufacturing and logistics is a research hotspot, but there is no good way to estimate the external stochastic disturbance factors and its nonlinear effect on environmental capacity in the existing research. To address this issue, a co-evolution population ecosystem of manufacturing and logistics is defined from the perspective of organizational ecology, and the external environmental capacity(EEC) model is established based upon logistic equation, and its stochastic influence factors are analyzed by the method of mathematical statistics. Finally, the effectiveness of the model proposed in this paper is validated through case study.
ERP implementations are complex undertakings. The purpose of this study is to establish ERP implementation model in China firms based on project life cycle theory. ERP implementation is an information system project. Drawing from literature research, case research, experts-interview, questionnaire investigation, a critical success factors model is developed that posits that ERP implementation is mostly influenced by top manager support, project champion, external experts, education & training, accuracy of data, project management factors. The research, divided the project of ERP implementation into programming, executive, stabilization, ascending four phases based on project life cycle, investigates the critical success factors in ERP implementation to provide a better understanding of the key factors leading to implementation success when plarming ERP implementation projects and also provides researchers with a foundation for further empirical research.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
