浅析建筑物鉴定中的计数抽样方案 总被引:1,自引:0,他引:1
在介绍计数型抽样检验原理的基础上,从建筑物鉴定检测的特点出发提出了采用相应抽样检验国家标准的建议。指出GB/T50344-2004《建筑结构检测技术标准》中关于计数抽样检测方案的规定失之过松,有可能给建筑物的检测或鉴定留下安全隐患,不宜采用。 相似文献

Diagnostic clinics are among healthcare facilities that suffer from long waiting times which can worsen medical outcomes and increase patient no-shows. Reducing waiting times without significant capital investments is a challenging task. We tackle this challenge by proposing a new appointment scheduling policy that does not require significant investments for diagnostic clinics. The clinic in our study serves outpatients, inpatients, and emergency patients. Emergency patients must be seen on arrival, and inpatients must be given next day appointments. Outpatients, however, can be given later appointments. The proposed policy takes advantage of this by allowing the postponement of the acceptance of appointment requests from outpatients. The appointment scheduling process is modeled as a two-stage stochastic programming problem where a portion of the clinic capacity is allocated to inpatients and emergency patients in the first stage. In the second stage, outpatients are scheduled based on their priority classes. After a detailed analysis of the solutions obtained from the two-stage stochastic model, we develop a simple, non-anticipative policy for patient scheduling. We evaluate the performance of this proposed, easy-to-implement policy in a simulation study which shows significant improvements in outpatient indirect waiting times. 相似文献
