Currently, the construction sector is facing requirements for higher quality and efficiency standards as well as objectives related to value creation. In construction, rational decision-making problems often involve creating a unique complex of criteria, which must consider multiple requirements and conditions. The paper presents the developed model for the selection of multi-layered external walls of a residential building. The model considers the following aspects and parameters: time, cost, quality, environmental conditions, aspects of sustainable development, and problemsolving benefits received from the assessment of alternatives and the development of the model. Game theory was used to calculate the defining rational decision. For the calculations was used game theory: Bayes, Wald’s rule, Savage criterion, Laplace’s rule. This study presents the developed model for the selection of multi-layered external walls of a residential building and calculation results based on game-theory rules, which are effective tools for rational decisionmaking.

Rational Decision Making

Central America is an interesting region for developing business, and its proximity to South and North America makes the isthmus a strategic region for growth. Guatemala is seen as an emerging economy with the capacity for growth and expansion. The cement industry is now one of the most competitive industries in Central America and has expanded to different countries in the region. However, this was not the case in 1999 when the Mexican Firm Cruz Azul entered via a price predation strategy into the Guatemalan market. Game theory demonstrates the advantage of price predation and the rational decision-making behind the strategy, and also demonstrates that a business smaller than its competitors can win a price predation battle by cooperating. The analysis is based on the dissertation by Garita (2008).

Energy saving of buildings in our country started from 90’s,which is so late that remaining at a low level .Although certain success has been achieved ,architecture reconstruction moves slowly on the whole ,especially for residential buildings. One of the reasons for this situation is lacking of money for energy saving reconstruction .Considering the enormous number of energy saving reconstruction buildings with the limited funds ,human resource and material resource, it is necessary to make a selection before the reconstruction ,weeding out the projects that are too poor to reconstruct in safety, functionality and energy-saving reconstruction, as well as the ones that have good energy saving performance and meet the energy efficiency design standards, which aren’t built for ages. The key point is to choose the existing buildings which are in urgent need of transformation in performance, economically rational and have feasible technic proceeding in batches with plans. Meanwhile, the reconstruction should use appropriate technology, combining with local climate characteristics.

Water Meter

Experimental measurements of actual hot water consumption in residential building have been performed. It was established that distribution of hot water for domestic needs has random character and constitutes non-stationary process. It was proposed for hot water supply systems calculation to employ “rated mode of water consumption”. Rated mode is a simplified mathematical description of entire ordered collection of hourly consumptions anticipated during rated period of hot water supply system operation. Most precise description of water consumption rated mode may be obtained with coefficient of general hourly discontinuity at 98% coverage. Selection of hot water metering devices for residential house requires that operating flow rate of water meter should correspond by maximum to residential building water consumption parameters. Methods of calculation of daily water volumes passing through water meter at flow rates lower than transient flow rate value for the specified device were proposed.

This paper presents a selection of vibration measurement results and analyses performed with regard to their harmfulness to residential buildings. The first part of the paper refers to the analysis of railway vibrations measured in situ at the foundation level of residential building. These vibration records were then used to assess the harmfulness of vibrations relating to each train speed. Assessment of the vibration harmfulness of the building was performed with an indicator of the perceptibility of vibration through a structure (WODB), according to the Polish standard. The second part of the study refers to the creation of dynamic models of buildings with the use of the ‘Diana’ software program and analysis of their responses to railway vibrations. The thresholds specified by the standard in any of the train speeds of up to 250 km/h were not exceeded. Nevertheless, propagation of vibrations induced by train passages and their effect on the structural response of buildings is a complex phenomenon. Without in situ measurements, it is hard to assess the impact of induced vibrations on buildings. As proven in the paper, a train moving on a track at various speeds does not uniformly make the vibration greater in each frequency band.

High residential living in Malaysia has not been widely given a significant emphasises in literature despite its increasing scale and significance in the real estate market. The significance of high rise is mainly due the increasing rate of migration from rural to urban. It is estimated a total of 77.2 percent of the Malaysian population lived in urban areas in 2020. Approximately, 30 percent of this urban population lives in strata housing. These percentages are predicted to continue to increase in the future. The emergence of high residential building has been argued as confronting various problems which has considerable impact on this life style. Satisfaction is an important outcome of living in one’s dwelling, although it is not the only consideration. High residential building in Malaysia encountered numerous problems in term of management aspects, legislation aspects, and residents’ satisfaction. The purpose of this paper is to investigate the tenants’ satisfaction living in high residential buildings in Klang Valley. The questionnaires survey is conducted amongst 276 tenants at low cost and medium cost HRB using random sampling in HRB located at areas under jurisdiction Dewan Bandaraya Kuala Lumpur (DBKL), Majlis Bandaraya Subang Jaya (MBSJ), Majlis Bandaraya Shah Alam (MBSA), Majlis Bandaraya Subang Jaya (MBSJ), Majlis Perbandaran Selayang (MPS) and Majlis Perbandaran Ampang Jaya (MPAJ). The result from this study shows that tenant in medium cost residential building are more satisfied in term of facilities and management as compared to tenants in low cost residential building. Tenants also not disclosed to the existing act and procedure related to high residential building. In conclusion, this study suggested the Local Authority to emphasise the role of tenant. These recommendation hopefully will increase the level of satisfaction amongst the residents in HRB.

In this paper, we extend the quantum game theory of Prisoner’s Dilemma to the N-player case. The final state of quantum game theory of N-player Prisoner’s Dilemma is derived, which can be used to investigate the payoff of each player. As demonstration, two cases (2-player and 3-player) are studied to illustrate the superiority of quantum strategy in the game theory. Specifically, the non-unique entanglement parameter is found to maximize the total payoff, which oscillates periodically. Finally, the optimal strategic set is proved to depend on the selection of initial states.
