估算系统的开发费用以及运行、维护费用，预测系统运行后将获得的效益，并将

Estimate the development cost, operation and maintenance costs of the system, predict the benefits that will be obtained after the system is in operation, and compare the costs with the benefits to see if it is beneficial. The various expenses are mainly the expenses for the installation environment configuration of computer hardware, system software, etc. Dormitory management requires the modification, addition, and deletion of all personnel information in the apartment, as well as apartment hygiene, safety, and spare parts management. Its functions are relatively simple and intuitive, so it consumes less manpower and financial resources, and can be completed by one or a few people There is enough time, so the college student apartment management system is economically feasible. The system interface is friendly, the operation is simple, and the operation configuration is not high, so it is economically feasible. The system can be well deployed on the company or the Internet. Users can log in to the system at any time to query student dormitory, accommodation information, and can keep up to date with the latest accommodation information, which provides good convenience for the specification and practicality of the information. In terms of accident cause theory of the system, the emphasis is on improving the safety of the system by improving the reliability of the (hardware) object, thereby changing the past. People only focused on the unsafe behavior of the operator and ignored the role of hardware failure in the cause of the accident Traditional concept. People who are elements of the system will make mistakes when they perform their functions. Human errors include not only the unsafe behavior of workers, but also the errors of designers, managers, and other personnel. Therefore, the study of human factors is more in-depth than before. According to the principles of system safety, early in the planning and design stage of a new system, we must start to pay attention to safety work, and it must be through manufacturing, installation, and commissioning, until the end of the entire system life cycle. System safety work includes a series of contents such as hazard source identification, system safety analysis, hazard evaluation and hazard control.

估算系统的开发费用以及运行、维护费用，预测系统运行后将获得的效益，并将费用与效益进行比较，看是否有利。各种费用主要是计算机硬件、系统软件等安装环境配置的费用。宿舍管理要求做到对本公寓所有人员信息的修改、添加、删除以及公寓卫生、安全、备品管理，其功能比较简单直观，所以其消耗的人力财力少，由一个人或几个人就能完成，并且有足够的时间，所以大学生公寓管理系统在经济方面是可行的。系统界面友好，操作简单，操作配置不高，因此经济可行。该系统可以很好的部署在公司或者互联网上，用户可以随时登陆系统进行查询学生宿舍，住宿信息，可以随时掌握最新的住宿信息，对信息的规范和实用性提供很好的方便。系统的在事故致因理论方面,强调通过改善物的(硬件)的可靠性来提高系统的安全性,从而改变了以往人们只注重操作人员的不安全行为而忽略硬件故障在事故致因中作用的传统观念。作为系统元素的人在发挥其功能时会发生失误。人的失误不仅包括了工人的不安全行为，而且涉及设计人员、管理人员等各类人员的失误，因而对人的因素的研究也较以前更深入了。根据系统安全的原则，早在一个新系统的规划、设计阶段，就要开始注意安全工作，并且要一-直贯穿于制造、安装、投产，直到报废为止的整个系统寿命期间内。系统安全工作包括危险源识别、系统安全分析、危险性评价及危险控制等一系列内容。

Estimate the development cost, operation and maintenance cost of the system, predict the benefits to be obtained after the operation of the system, and compare the costs and benefits to see whether it is beneficial. All kinds of costs are mainly the cost of computer hardware, system software and other installation environment configuration. Dormitory management requires the modification, addition and deletion of all personnel information of the apartment, as well as the management of health, safety and spare parts of the apartment. Its function is simple and intuitive, so it consumes less human and financial resources, can be completed by one or several people, and has enough time, so the management system of College Students' apartment is feasible in terms of economy. The system has friendly interface, simple operation and low configuration, so it is economical and feasible. The system can be well deployed in the company or on the Internet, users can log in the system at any time to query student dormitory, accommodation information, can grasp the latest accommodation information at any time, providing a good convenience for the specification and practicability of information. In terms of the theory of accident cause, the system emphasizes to improve the safety of the system by improving the reliability of the object (hardware), thus changing the traditional concept that people only pay attention to the unsafe behavior of the operator and ignore the role of hardware failure in the accident cause. People as system elements make mistakes when they perform their functions. Human errors not only include the unsafe behaviors of workers, but also involve the mistakes of designers, managers and other personnel. Therefore, the research on human factors is more in-depth than before. According to the principle of system safety, as early as in the planning and design stage of a new system, attention should be paid to safety work, and it should run through the whole system life period from manufacturing, installation, production to scrapping. System safety work includes hazard identification, system safety analysis, hazard assessment and hazard control.<br>
