为有效评价分布式供能企业运行的经济性,以内燃机分布式供能企业为研究对象,在满足客户冷热需求的前提下,建立了边际效益系数计算模型。通过计算不同运行模式下的边际效益系数,可有效确定不同条件下内燃机分布式供能企业的经济运行模式... 为有效评价分布式供能企业运行的经济性,以内燃机分布式供能企业为研究对象,在满足客户冷热需求的前提下,建立了边际效益系数计算模型。通过计算不同运行模式下的边际效益系数,可有效确定不同条件下内燃机分布式供能企业的经济运行模式。案例分析表明,在实际运行中,并非所有运行工况下选择内燃机溴化锂机组联产供能的运行模式均为最好。当冷热负荷增加时,应选择边际效益系数最大的生产模式增产;当冷热负荷减小时,应选择边际效益系数最小的生产模式减产。 展开更多

In clinic's appointment scheduling system no-shows have been a significant and confirmed issue with a bad influence on patient accessibility and clinic efficiency. The problem of walk-in has often been seen as the opposite of no-show problem. In this work we revisit a walk-in admitting based approach to mitigate the bad influence of no-show without overbooking. First we establish a model which utilizes marginal benefit objective function to balance the interests of the clinic, the patient and the doctor, we prove that no-show and walk-in cancels out each other straightly has a bad property. Then we propose a new rule which is an extension of the well-known Bailey - Welch rule, the simulation results show that our rule has an improvement comparing with the common rule that cancels them out straightly. 展开更多
