电子阅览室管理的方法与思路

// 电子阅览室管理系统基础架构示例
public class ElectronicReadingRoom
{
    public int Id { get; set; }
    public string Name { get; set; }
    public int Capacity { get; set; }
    public DateTime OpenTime { get; set; }
    public DateTime CloseTime { get; set; }
    public ICollection Computers { get; set; }
    public ICollection Resources { get; set; }
}

public class Computer
{
    public int Id { get; set; }
    public string IPAddress { get; set; }
    public string Status { get; set; }
    public DateTime LastMaintenance { get; set; }
    public int ReadingRoomId { get; set; }
    public ElectronicReadingRoom ReadingRoom { get; set; }
}

public class DigitalResource
{
    public int Id { get; set; }
    public string Title { get; set; }
    public string Category { get; set; }
    public string FileType { get; set; }
    public long FileSize { get; set; }
    public int AccessCount { get; set; }
    public int ReadingRoomId { get; set; }
    public ElectronicReadingRoom ReadingRoom { get; set; }
}

// 智能推荐算法示例
class ResourceRecommender {
  constructor() {
    this.userHistory = new Map();
    this.resourceTags = new Map();
  }

  // 基于用户历史记录推荐资源
  recommendResources(userId, maxResults = 10) {
    const userHistory = this.userHistory.get(userId) || [];
    const userPreferences = this.analyzeUserPreferences(userHistory);
    
    return this.calculateRecommendations(userPreferences)
      .sort((a, b) => b.score - a.score)
      .slice(0, maxResults);
  }

  // 分析用户偏好
  analyzeUserPreferences(history) {
    const preferences = new Map();
    
    history.forEach(record => {
      const tags = this.resourceTags.get(record.resourceId) || [];
      tags.forEach(tag => {
        preferences.set(tag, (preferences.get(tag) || 0) + 1);
      });
    });
    
    return preferences;
  }

  // 计算推荐分数
  calculateRecommendations(preferences) {
    // 实现推荐逻辑
    return [];
  }
}
