摘要：We propose a new consensus model for group decision making(GDM) problems, using an interval type-2 fuzzy environment. In our model, experts are asked to express their preferences using linguistic terms characterized by interval type-2 fuzzy sets(IT2 FSs), because these can provide decision makers with greater freedom to express the vagueness in real-life situations. Consensus and proximity measures based on the arithmetic operations of IT2 FSs are used simultaneously to guide the decision-making process. The majority of previous studies have taken into account only the importance of the experts in the aggregation process, which may give unreasonable results. Thus, we propose a new feedback mechanism that generates different advice strategies for experts according to their levels of importance. In general, experts with a lower level of importance require a larger number of suggestions to change their initial preferences. Finally, we investigate a numerical example and execute comparable models and ours, to demonstrate the performance of our proposed model. The results indicate that the proposed model provides greater insight into the GDM process.

摘要：目的评价剂量表面积直方图(DSH)对前列腺癌(PCa)患者急性放射性直肠炎(RP)的预测价值。方法本研究为前瞻性随机对照临床研究。收集2018年1月-2023年1月河北北方学院附属第一医院放疗科收治的380例PCa患者,采用抽签法随机分为观察组(n=200)与对照组(n=180)。采用DSH评价观察组直肠剂量分布,剂量体积直方图(DVH)评价对照组直肠剂量分布。采用受试者操作特征(ROC)曲线评价两种计划评价工具对急性RP的预测效能。结果两组年龄、RPS评分、体重指数(BMI)等临床资料比较差异均无统计学意义(P>0.05)。两组急性RP级别比较差异无统计学意义(P>0.05)。两组S_(40)与V_(40)、S_(50)与V_(50)、S_(60)与V_(60)、S_(70)与V_(70)、S_(78)与V_(78)比较差异均有统计学意义(P0.900,提示高等效能(P<0.001)。结论DSH对PCa患者直肠毒性的预测效能与DVH较为相似,在未来放射治疗计划设计中可弥补DVH的不足或单独用于计划评价。

摘要：As gas recirculation constitutes a fundamental condition for the realization of MILD combustion, it is necessary to determine gas recirculation ratio before designing MILD combustor. MILD combustion model with gas recirculation was used in this simulation work to evaluate the effect of fuel type and pressure on threshold gas recirculation ratio of MILD mode. Ignition delay time is also an important design parameter for gas turbine combustor, this parameter is kinetically studied to analyze the effect of pressure on MILD mixture ignition. Threshold gas recirculation ratio of hydrogen MILD combustion changes slightly and is nearly equal to that of 10 MJ/Nm3syngas in the pressure range of 1-19 atm, under the conditions of 298 K fresh reactant temperature and 1373 K exhaust gas temperature, indicating that MILD regime is fuel flexible. Ignition delay calculation results show that pressure has a negative effect on ignition delay time of 10 MJ/Nm3syngas MILD mixture, because OH mole fraction in MILD mixture drops down as pressure increases, resulting in the delay of the oxidation process.
