System dynamics tool for entropy-based risk control on sleeve grouting in prefabricated buildings

<jats:sec><jats:title content-type="abstract-subheading">Purpose</jats:title>
<jats:p>The production of sleeve grouting in prefabricated construction is routinely plagued by a variety of factors, and lack of mass data and complex environmental conditions over time make problems inevitable. Thus, a dynamic risk control system is a valuable support for the successful completion of the sleeve grouting process. This study aims to develop an entropy-based sleeve grouting risk dynamic control system.</jats:p></jats:sec>

<jats:p>First, static risk assessment was conducted through the structured interview survey using the entropy weight method, followed by a dynamic risk control technique, where indicators were simulated through system dynamics containing causal loop diagrams and stock-and-flow diagrams.</jats:p></jats:sec>

<jats:p>Finally, three types of risk control models, namely, “tortuous type”, “stable type” and “peak loop type”, were developed in the entropy-based sleeve grouting risk dynamic control system and simulated using system dynamics in a real case.</jats:p></jats:sec>
