The data contains information for the patients of a single nurse who is responsible to visit them. In each folder, there are different number of patients for the same nurse and further the data is divided as loose time windows and tight time windows in each folder. In each folder, there is a Data.csv file which contains patients' ID, their geographic information, the time windows in which they can be visited, the last visit date which represents the last visit date the nurse has visited the patients. The Distance file contains geographic distance matrix in terms of meters from nurse's home location to patients and from patients to patients.本数据集包含一名负责上门巡访患者的护士所服务的全部患者相关信息。每位护士对应一个独立文件夹，同一护士的不同文件夹内所包含的患者数量各不相同，且每个文件夹内的数据均按宽松时间窗与严格时间窗两类进行划分。每个文件夹内均包含一个Data.csv文件，该文件记录了患者ID、患者地理位置信息、患者可接受巡访的时间窗，以及护士末次巡访该患者的日期。Distance文件则包含以米为单位的地理距离矩阵，涵盖护士居家位置至各患者的距离，以及患者间的两两距离。
