Staff scheduling support systems aimed at maintaining the quality of nursing and care services

一项旨在维持护理和护理服务质量的工作人员调度支持系统的研究产生了三个主要结果。(1)利用Microsoft Excel开发了一个“家政服务人员排班支持系统”原型，并在此基础上开发了一个基于Web的家政服务人员排班支持系统。(2)将未解决的护士调度问题处理为混合整数问题或可满足性问题，可以得到这些问题的精确解。(3)我们认为，将可行解表示为网络所获得的信息对于调度员确定人员调度问题是有效的。

A study of staff scheduling support systems designed to maintain the quality of nursing and care services yielded three main results. (1) We developed, in Microsoft Excel, a prototype "home help staff scheduling support system" and a web-based system based on the prototype. (2) We could obtain exact solutions for instances of nurse scheduling problems which were previously unsolved, by dealing with these instances as mixed integer problems or satisfiability problems. (3) We suggest that the information obtained by representing feasible solutions as a network is efficient for schedulers to ascertain staff scheduling problems.
