Background: Fire is one of the potential dangers that threatens human activities more and more. Given that, this study sought to introduce the factors preventing the spread of fire in hospitals to policymakers through prioritization based on the techniques of applied mathematics (multi-attribute decision-making technique). Methods: This study consisted of two stages. In the first stage, through a comprehensive review of studies, factors preventing the spread of fire were identified, and then in the second stage, based on the experts’ opinions, the attributes affecting the prioritization and their weights were determined. Finally, based on the Simple Additive Weighting (SAW) model, the final prioritization was done for five types of hospital buildings. Results: Based on the literature review and experts’ opinions, seven factors and four attributes were identified. The most important factors were “the use of safety architecture and equipping with appropriate emergency exit accesses according to the standard” in highrise hospitals, “continuous firefighting training of the personnel” in wide hospitals, “use of fire extinguishing systems (automatic and manual)” in subsurface hospitals, “use of fire extinguishing systems (automatic and manual)” in combined hospitals, and “continuous firefighting training of the personnel” in portable hospitals. Conclusions: Fire safety is not limited to the installation of a manual fire extinguisher, but for fire safety, especially in hospitals, all aspects should be considered, including the architectural form of the building, how the materials and equipment in the building caught fire, fire behavior in terms of heat transfer, the firefighting training of the personnel, recognition, and application of modern and ready-made equipment for smoke ventilation systems and fire products, automatic and manual fire alarm systems, and extinguishing systems to prevent the spread of fire.

Fuzzy logic is widely applied to daily life with various methods. One method is fuzzy multi-attribute decision making (FMADM). FMADM is able to select the best alternative from a number of alternatives. In FMADM there is a supporting method so that the results obtained are accurate and optimal, namely the classic MADM method. One method in classic MADM is the Simple Additive Weighting (SAW) method. The SAW method is precisely used to minimize diagnostic errors, but if a decision support system is made, the SAW method still requires a further development method, one of which is the FMADM method with its development. The purposes of this study are to describe the steps of SAW method and the development of FDM in theory, implement SAW method and the development of FDM to diagnose a type of disease and implement it in a decision support system using GUI matlab. The completion step of those two methods is through two stages, the first one will go through FMADM stage with SAW, which is weighted sum, then the output will be used as input to the FDM method based on total integral values. The result of this study is proven by patient experienced initial symptoms of high fever at a temperature of 39.5° C - 40° C, very much spots appear in rumple leed test (> 50 petheciae), bleeding gums, rarely got nausea and headache, as well as diarrhea. Accuracy for the decision support system using MAPE was obtained 93% so that the decision support system with FMADM method to diagnose the disease was feasible to use.

Abstract In Hungary a lot of people live in condominiums or in block of flats where fire often occurs despite of precise design and effective fire protection arrangements. This means a hazard for the people living there, for the building constructions and also for the environment. A deeper knowledge of the burning process and examining the negative effects of fire load on building constructions with scientific methods are actual questions nowadays. In order to get to know the phenomena more accurately, fire spread in a bedroom was modeled and numerical simulation was carried out, which is presented in this paper in detail. These experiences may help increasing the fire safety and preventing fires in apartments. The simulations were carried out considering the characteristics of the Hungarian architecture.

Fire Information

At present, the automatic fire alarm systems on sale were produced by different factories, which resulted in the information not being shared mutually. Furthermore, it was difficult to connect the different fire auto-alarm systems to the same network. They couldn't communicate automatically with the city fire-fight commanding center in time. We designed interface module of automatic fire alarm controller network and interface module of data center network. By using the existing net of PSTN and internet, it could transmit the breakdown information and a fire information of the automatic fire alarm systems to the fire-fight commanding center, the long-range diagnose, the real-time monitor of a fire and the long-range control in the city fire auto-alarm system was realized.

In Fire

Actual and future concerns in fire safety in buildings and infrastructure are challenging. Modern technologies provide rapid development in area of fire safety, especially in education, training, and fire-engineering. Modelling as a tool in fire-engineering provides possibility to design specific fire scenarios and investigate fire spread, smoke movement or evacuation of occupants from buildings. Development of emerging technologies and software provides higher possibility to apply these models with interactions of augmented and virtual reality. Augmented reality and virtual reality expand effectivity of training and preparedness of first (fire wardens) and second (firefighters) responders. Limitations such as financial demands, scale and scenarios of practical training of first and second responders are much lower than in virtual reality. These technologies provide great opportunities in preparedness to crisis in a safety way with significantly limited budget. Some of these systems are already developed and applied in safety and security area e.g. XVR (firefighting, medical service).
