“…For the convenience of computing, index x 2 need to be quantified. Thus, take “No worm holes along the length, no hollowing sounds while knocking” as 1; take “No obvious worm holes along the length, no hollowing sounds while knocking” as 2; take “Obvious worm holes along the length, no hollowing sounds while knocking” as 3; take “Obvious worm holes along the length, hollowing sounds are heard while knocking” as 4 (Li et al, 2009). Based on site-investigation results, R 0 is established to evaluate matter-element matrix of L 1 …”

This article investigates various factors that may influence the safety state of ancient timber architecture, to improve the accuracy of safety-state evaluation results for ancient timber architecture. During the process, a safety-state evaluation system for ancient timber architecture is developed. This safety-state evaluation system includes five parts: foundation, plinth, timber frame, enclosing wall, and roof. Based on the system, a safety-assessment model for ancient timber architecture based on structural entropy weight–matter element extension model is also introduced. In this model, the structural entropy weight method is applied to calculating the weight of each index and takes the influence of subjective and objective weights into consideration comprehensively. This model has the following three detailed steps. First, correlation function and correlation degree of extension set are used to quantify the relationship between the evaluation indexes of the components, joints, and evaluation interval of each safety state. Second, the safety states of units are determined according to the distribution of safety state of the components. Third, the safety degree of the entire structure is determined via the minimum safety state of units. This study also uses the Niaoqiangsanchu in Forbidden City as a study case and found that the evaluation results are consistent with the results of the practical damage survey and the actual situation of the architecture. The model thus minimizes the uncertainty of qualitative and quantitative factors in the process of evaluating the safety degree of ancient timber architecture, to finally obtain the objective evaluation results.

“…An actual example was shown for the application of the method, and the result was exact and reasonable. Li et al (2009) applied a dynamic model based on a variable matter element with parameters to construct the early warning model of airport safety. A case study showed that Li's model was suitable for evaluation of airport safety, and for assisting early warning decision quantitatively.…”

Firstly, the early warning index system of general airport safety based on the matter element extension theory was established on four aspects：flight safety support system, apron safety support system, comprehensive support system and logistics support system. And, early warning levels of general airport safety were classified and the weights of all indexes were measured by Analytic Hierarchy Process (AHP). Then, with the application of the matter elements extension theory, the matter element model for the general airport safety system was established, which included 4 early warning levels (no early warning, slight early warning, moderate early warning, severe early warning). After that, taken the correlative degree as an evaluation criterion, a final early warning level of general airport safety was deduced by constructing extension correlation functions. At last, the model was verified by an example on Guanghan airport in 2012, which indicated that the model was suitable for evaluating the general airport safety，and for assisting early warning decision quantitatively.
