“公文流转系统 v1.0”

2024-04-11 09:42:01

1、项目需求：

河北金力集团是我省机械加工的龙头企业，主要从事矿山机械制造及各种机械零部件加工。企业有3个厂区，主厂区位于省高新技术开发区，3个分厂分别在保定、邢台和唐山。为增加企业的核心竞争力和加强管理的科学程度，近期企业将在全集团实行ERP管理，建立网页版公文流转系统。具体部门：主厂区、一分厂、二分厂、三分厂、销售部门、财务部门、办公室；领导：三位副厂长(分别管理生产、销售、财务)、一位厂长。

2. 板块功能需求

（1）、页面要求

① 能适应800*600或1024*768分辨率；

② 布局合理、结构清晰、页面完整；

③ 有效页面数在8页以上；

④ 分页与主页风格统一；

⑤ 首页(登录页)：用户登录页(共有十位用户帐号，帐号、密码可预设)。不同用户登录后，进入的功能页不相同，要求密码在数据库中加密。

⑥ 部门(不含办公室)功能页：有公文拟制、签收公文、浏览公文(已签收的公文)三个模块

⑦ 办公室功能页：有修改公文、公文流转、删除公文、公文发送等功能。

⑧ 副厂长功能页：有审核公文(修改并签意见)、浏览已发所有公文、查询公文三个模块。

⑨ 厂长功能页：有审签公文(修改并签意见)、浏览已发所有公文、查询公文三个模块。

⑩ 系统管理功能页：有用户管理、角色管理、公文流转流程管理。

（2）、功能设计：

  1. 公文拟制：创建新的电子公文，对创建的电子公文进行上传操作。
  2. 签收公文：当接收方接收公文后，会给发送方发回执信息，确认公文已经收到。
  3. 浏览公文(已签收的公文)：

1) 选择日期段。

2) 通过“查询”功能，显示该时间段内已通过审签的正式公文。

3) 点击公文标题，将会显示出该公文的具体信息。

  1. 修改公文：对拟制好的的电子公文进行格式化处理操作，套用公文样例。
  2. 公文流转：按照公文流转流程设定公文接收用户。
  3. 删除公文：如果该公文没有通过审核或审签，需要删除可以利用“删除”功能。确定后，系统提示公文删除成功，删除的公文将在“被删除公文”模块中的显示。
  4. 公文发送：操作员要根据单位管理员选择的公文的流程进行公文的流转发送，实现待发公文和已发送公文的管理
  5. 审核公文(修改并签意见)：签署审核意见和修改意见，并将退回办公室。
  6. 有审签公文(修改并签意见)：签署审前意见和修改意见，若同意，则生成正式公文并交由办公室转发。
  7. 浏览已发所有公文：按日期查看所有已发公文，点击标题可查看具体信息。
  8. 公文查询：是查询由公文交换系统处理过的公文，并且建立或检查公文详尽的索引信息。可以根据发送机构、接收机构、公文种类和其它开放信息进行公文数据查询。
  9. 系统管理：

a)  角色配置管理

  1. 用户权限维护功能：实现对用户的角色管理。
  2. 角色维护功能：实现对角色权限的管理，主要有编辑、增加和删除操作。

b) 用户管理：查看用户、新开用户、暂停用户、用户信息修改、删除用户

c) 单位管理员设置功能：每个单位的操作员实现修改密码、修改个人信息。

 

系统架构分析：

　　1.完成用户登录系统的设计，其中有关后台管理系统默认用户登录信息，需连接数据库并自定义表进行录入；

　　2.根据项目功能要求及其参与者种类可以将每个角色的功能分页进行，然后严格按照公文流转流程进行整合；

　　3.对公文流转过程进行细化，严格遵循流转流程实现各用户交互功能；

　　4.优化系统设计

　　　　a）添加用户信息管理功能即后台系统管理员可对用户的登录信息进行增删改查；

　　　　b）以公文文件为主体可以添加相关增删改查功能，以便进行后台综合管理
