好的,我选择使用Python语言来实现先来先服务调度算法。下面是代码实现:
```python
class Process:
def __init__(self, pid, arrival_time, burst_time):
self.pid = pid
self.arrival_time = arrival_time
self.burst_time = burst_time
def FCFS(processes):
n = len(processes)
wait_time = 0
total_wait_time = 0
turnaround_time = 0
total_turnaround_time = 0
current_time = 0
for i in range(n):
if processes[i].arrival_time > current_time:
current_time = processes[i].arrival_time
wait_time = current_time - processes[i].arrival_time
total_wait_time += wait_time
turnaround_time = wait_time + processes[i].burst_time
total_turnaround_time += turnaround_time
current_time += processes[i].burst_time
avg_wait_time = total_wait_time / n
avg_turnaround_time = total_turnaround_time / n
print("Process\tArrival Time\tBurst Time\tWait Time\tTurnaround Time")
for i in range(n):
print(f"{processes[i].pid}\t\t{processes[i].arrival_time}\t\t{processes[i].burst_time}\t\t{current_time - processes[i].arrival_time - processes[i].burst_time}\t\t{current_time - processes[i].arrival_time}")
print(f"Average Wait Time: {avg_wait_time:.2f}")
print(f"Average Turnaround Time: {avg_turnaround_time:.2f}")
```
以上是一个基于先来先服务调度算法的进程调度程序,通过传入一个包含各个进程信息的列表参数,程序会自动计算出每个进程的等待时间和周转时间,最终输出所有进程的详细信息以及平均等待时间和平均周转时间。
