任务协作平台对接 AI 工具：智能任务分配、自动进度提醒、数据分析实践案例

// 智能任务分配算法示例
class IntelligentTaskAssigner {
  constructor() {
    this.memberProfiles = new Map();
    this.taskQueue = [];
  }

  // 评估成员与任务的匹配度
  calculateMatchScore(memberProfile, taskRequirements) {
    const skillMatch = this.calculateSkillSimilarity(
      memberProfile.skills, 
      taskRequirements.requiredSkills
    );
    const workloadScore = this.calculateWorkloadFactor(memberProfile.currentWorkload);
    const historicalPerformance = memberProfile.successRate;
    
    return (skillMatch * 0.5) + (workloadScore * 0.3) + (historicalPerformance * 0.2);
  }

  // 分配任务给最合适的成员
  assignTaskToBestMember(task) {
    let bestMember = null;
    let highestScore = 0;

    for (const [memberId, profile] of this.memberProfiles) {
      const score = this.calculateMatchScore(profile, task.requirements);
      if (score > highestScore) {
        highestScore = score;
        bestMember = memberId;
      }
    }

    return bestMember;
  }
}

// 自动进度提醒服务实现
public class AutomatedProgressNotifier
{
    private readonly ITaskRepository _taskRepository;
    private readonly INotificationService _notificationService;
    
    public AutomatedProgressNotifier(ITaskRepository taskRepository, 
                                   INotificationService notificationService)
    {
        _taskRepository = taskRepository;
        _notificationService = notificationService;
    }
    
    // 检查需要提醒的任务
    public async Task CheckAndNotifyAsync()
    {
        var approachingDeadlines = await _taskRepository
            .GetTasksApproachingDeadlineAsync(DateTime.Now.AddHours(24));
        
        foreach (var task in approachingDeadlines)
        {
            var message = BuildReminderMessage(task);
            await _notificationService.SendAsync(task.AssignedTo, message);
        }
        
        var stalledTasks = await _taskRepository.GetStalledTasksAsync(TimeSpan.FromHours(48));
        foreach (var task in stalledTasks)
        {
            var alertMessage = BuildStalledTaskAlert(task);
            await _notificationService.SendAsync(task.AssignedTo, alertMessage);
            await _notificationService.SendAsync(task.ProjectManager, alertMessage);
        }
    }
    
    private string BuildReminderMessage(TaskItem task)
    {
        return $"提醒：任务 '{task.Title}' 即将在 {task.Deadline:yyyy-MM-dd HH:mm} 到期。当前进度：{task.ProgressPercentage}%";
    }
}
