研究生复试含面试环节,某院研究生面试采用多对一的面试方式,对1个学生的面试称为一场面试。安排每场面试需要5位教师,有10间教室可作为面试场,每间教室安排的老师固定不变。每个面试场之间的面试进程相对独立,一位学生面试完毕后,可以马上进行下一位学生的面试。该院可参加面试的教师共有88人,参加面试的学生有102人,每位教师均可担任专业面试教师。 一、根据以往经验,10间面试场每场的面试时间(单位:分钟)已确定,见下表:面试场编号 1 2 3 4 5 6 7 8 9 10面试时间 24.2 29.3 13.0 25.4 23.3 16.8 20.3 23.4 36.3 33.1 请设计每间面试场的面试人数使整个面试能尽早结束。分别使用python和matlab对上述进行解答

Python代码实现:
```python
import numpy as np
# 面试场次
num_rooms = 10
# 面试时间
interview_time = np.array([24.2, 29.3, 13.0, 25.4, 23.3, 16.8, 20.3, 23.4, 36.3, 33.1])
# 面试教师数
num_teachers = 5
# 每个面试场的教师数量
teachers_per_room = np.full((num_rooms, num_teachers), num_teachers)
# 每个面试场的面试时间
time_per_room = np.full(num_rooms, 0)
# 每个面试场的面试人数
num_students_per_room = np.full(num_rooms, 0)
# 每个教师能参加的面试场次数
num_rooms_per_teacher = np.full(88, 0)
# 每个学生的面试状态,0表示未面试,1表示已面试
interview_status = np.full(102, 0)
# 计算每个教师能参加的面试场次数
for i in range(88):
num_rooms_per_teacher[i] = int(num_rooms / 88)
if i < num_rooms % 88:
num_rooms_per_teacher[i] += 1
# 随机分配教师到面试场
teachers_index = np.arange(88)
np.random.shuffle(teachers_index)
for i in range(num_rooms):
# 随机选择教师
selected_teachers = np.random.choice(teachers_index, num_teachers, replace=False)
# 更新每个面试场的教师数量和面试时间
teachers_per_room[i] = selected_teachers
time_per_room[i] = np.sum(interview_time[i] / selected_teachers)
# 更新每个教师的面试场次数
for j in selected_teachers:
num_rooms_per_teacher[j] -= 1
# 分配学生到面试场
for j in range(102):
if interview_status[j] == 0:
# 找到一个教师没有超过参加面试场次数限制的面试场
for k in range(num_teachers):
if num_rooms_per_teacher[selected_teachers[k]] > 0:
interview_status[j] = 1
num_rooms_per_teacher[selected_teachers[k]] -= 1
num_students_per_room[i] += 1
break
# 输出每个面试场的面试人数和面试时间
print("每个面试场的面试人数:", num_students_per_room)
print("每个面试场的面试时间:", time_per_room)
