The contradiction between the effective supply and the uncertain demand in housing security system, which is an important part of the urban social security system, has been a major obstacle to urban sustainable development since 1998, and how to effectively deal with it is becoming more and more important. In this paper, the uncertain demand of indemnificatory housing, which was caused by the rapid urbanization, is considered, and the models for indemnificatory housing provision under box constraints, ellipsoid constraints and polyhedral constraints are constructed respectively by using distributional robust optimization, and at the same time, the reliability of optimal models in theory is proved in the form of theorem. In the end, as application of models, the paper takes Beijing as an example, and conducts empirical research on provision of indemnificatory housing during the past five years (2006-2010), which shows the effectiveness of the method.

Bilevel Programming Model

A bilevel programming model, in which the government could maximize its efficiency and the vulnerable housing group could maximize its utility, was constructed under the market-cleaning assumption in urban housing security, and then the optimal decision by vulnerable housing groups is discussed in government’s price for affordable housing with property right, and the existence of the optimal decision by consumers and government is proved, respectively. And at the same time, the constructed bilevel model is solved through the use of the smoothing method. Finally, the bilevel programming model is constructed under the uncertainty and the non-market-cleaning accordingly. The conclusion shows that it is reasonable to maximize consumer welfare and the efficiency of government in urban housing security system, and it makes recommendations for government decision-making accordingly.

Communication Needs

Smartphone technology can be applied not only to establish communication needs but also to support other purposes. One of them is related to personal safety and security functions. It is undeniable that criminal acts can occur anytime and anywhere. Even in a private or residential area, theft could happen. Smartphone and sensor technology can be used as a solution to encounter this problem. In this case, it can be utilized to improve the security control system of the gate or garage door at home. This research presents a prototype of a gate and garage door control and security system that operates through an application on an android smartphone. The application of HC-05 Bluetooth is used to send signals from the smartphone to the Arduino Uno microcontroller, while the micro servo acts as a locking mechanism on the gate itself. The buzzer function is presented to notify homeowners when the gate or garage door is open for more than 15 seconds. This prototype can control gates and garage doors with an average connection time of only about 5 seconds. Thus, this prototype is feasible to use as an alternative to control and improve housing security systems.
