手术排程算法R语句具体代码

手术排程算法的具体代码实现可以有多种不同的方法，以下是一种用R语言实现的例子：

# 定义手术列表
surgery_list <- data.frame(
  surgery_id = c(1, 2, 3, 4, 5),
  surgery_name = c("手术A", "手术B", "手术C", "手术D", "手术E"),
  surgery_duration = c(2, 3, 1, 2, 4),
  available_start_time = c(1, 2, 1, 3, 2)
)

# 定义手术室列表
operating_room_list <- data.frame(
  operating_room_id = c(1, 2, 3),
  operating_room_name = c("手术室A", "手术室B", "手术室C"),
  daily_available_time = c(8, 9, 10)
)

# 定义手术排程函数
schedule_surgeries <- function(surgery_list, operating_room_list) {
  # 按手术时间长短排序
  surgery_list <- surgery_list[order(surgery_list$surgery_duration),]
  
  # 初始化手术室占用情况
  operating_room_schedule <- data.frame(
    operating_room_id = operating_room_list$operating_room_id,
    start_time = rep(0, nrow(operating_room_list)),
    end_time = rep(0, nrow(operating_room_list))
  )
  
  # 遍历手术列表，将每个手术安排到可用的手术室中
  for (i in 1:nrow(surgery_list)) {
    surgery <- surgery_list[i,]
    available_rooms <- operating_room_list[operating_room_list$daily_available_time >= surgery$surgery_duration,]
    available_rooms <- available_rooms[available_rooms$operating_room_id %in% operating_room_schedule$operating_room_id,]
    available_rooms <- available_rooms[available_rooms$operating_room_id %in% 
                                          (operating_room_schedule$end_time < surgery$available_start_time),]
    if (nrow(available_rooms) == 0) {
      cat(sprintf("无法为手术 %s 安排手术室\n", surgery$surgery_name))
    } else {
      selected_room <- available_rooms[1,]
      start_time <- max(selected_room$daily_available_time - surgery$surgery_duration, surgery$available_start_time)
      end_time <- start_time + surgery$surgery_duration
      operating_room_schedule[operating_room_schedule$operating_room_id == selected_room$operating_room_id,]$start_time <- start_time
      operating_room_schedule[operating_room_schedule$operating_room_id == selected_room$operating_room_id,]$end_time <- end_time
      cat(sprintf("已为手术 %s 安排手术室 %s，开始时间为 %d，结束时间为 %d\n", 
                  surgery$surgery_name, selected_room$operating_room_name, start_time, end_time))
    }
  }
}

# 调用手术排程函数
schedule_surgeries(surgery_list, operating_room_list)

以上代码中，首先定义了手术列表和手术室列表，然后定义了一个名为`schedule_surgeries`的函数来实现手术排程。在函数中，首先按手术时间长短排序，然后遍历手术列表，将每个手术安排到可用的手术室中。在安排过程中，需要考虑手术室的可用时间和手术的开始时间等因素。最后，输出每个手术的安排结果。
