Building Life Cycle

Nowadays the maintenance problem of many-flat houses becomes one of the mostly debatable points. Greatly pressing questions are the quality of maintenance work and evaluation of public utilities. In this paper, the process of building maintenance is analyzed, in order to plan and carry out a more effective maintenance process. Striving for this aim the activities of subjects carrying out maintenance work, demands of building users were analyzed in a complex way and the comparison of maintenance variants was made. Striving for prolonging the time of building existence, it is necessary to increase maintenance quality and effectiveness in distributing resources, to improve organisational and management forms, to raise qualification of maintenance executives. The determination of the utility degree and value of the project under investigation and establishment of the priority order for its implementation does not present much difficulty, if the criteria numerical values and significances are obtained and the multiple criteria decision-making methods are used. The results of the comparative analysis of the projects are presented as a decision-making matrix where columns contain n alternative projects being considered, while all qualitative information pertaining to them is found in lines. Qualitative description of the project provides the information about the aspects of a building facility (i e convenience, work quality, health level of environment, noise level, work level, etc). Qualitative information is based on the criteria systems, units of measurement, values and initial significances as well as the data on the alternative projects development. In order to select the best project, it is necessary, having formed the decision-making matrix, to perform the multiple criteria analysis of the projects. One of the major tasks is to determine the significances of the criteria. When performing multiple criteria assessment of projects, it is necessary to normalise the values of criteria describing the projects and then to weigh them. The significances of all criteria must be coordinated among themselves. A method of multiple criteria evaluation of the projects discussed in this paper assumes a direct and proportional dependence of significance and priority of investigated versions on a system of criteria adequately describing the alternatives and on values and significances of the criteria. The system of criteria is determined and experts calculate the values and initial significances of criteria. All this information can be corrected by process participants (customer, users, etc) taking into consideration their pursued goals and existing capabilities. The degree of utility AT of a building life cycle is directly associated with quantitative and conceptual information related to it. A degree of building life cycle reflects the extent to which the goals pursued by the process participants are attained.

This chapter addresses the main issues that are worth considering when using environmental criteria in a multiple criteria decision making (MCDM) context and provides some guidance for a proper and efficient use of environmental criteria in a MCDM context. Among the main issues considered in this chapter, we can mention the definition and representation of criteria, their weighting, and their selection. The relation of criterion to other notions such as attribute, objective, goal, and indicator is also explained. Regarding the environmental criteria, we emphasize their main characteristics and indicate how these characteristics can support the users in selecting appropriate MCDM methods. An illustrative example about the selection of the best scenario for the treatment of a vacuum cleaner at the end of its life cycle is given. It shows the type of reverse supply chain problems in which environmental criteria can be used to evaluate and compare alternatives.

Building Life Cycle

The determination of the utility degree and value of the project under investigation and establishment of the priority order for its implementation does not present much difficulty if the criteria numerical values and significances are obtained and the multiple criteria decision-making methods used. The results of the project comparative analysis are presented as a decision-making matrix where columns contain n alternative projects being considered, while all quantitative information pertaining to them is found in lines. Quantitative description of the project provides the information about various aspects of a building life cycle (ie economical, technical, technological, infrastructural, legislative, etc). Quantitative information is based on the criteria systems and subsystems, units of measure, values and initial significances as well as the data on an alternative project. In order to select the best project, it is necessary, having formed the decision-making matrix, to perform the multiple criteria analysis of the projects. This is done by comparing criteria numerical values and significances and analysing the conceptual information of the investigated project. One of the major tasks is to determine the significances of the criteria. This paper presents a new method for complex determination of the criteria significances taking into account their quantitative and qualitative characteristics. When performing multiple criteria assessment of projects it is necessary to normalise the criteria values describing the projects and then to weight them. This creates a possibility to compare the criteria values with different measuring units and to determine the most efficient alternatives. The significances of all criteria must be coordinated among themselves. The method of complex determination of significances allows to determine significances of criteria which are maximally interrelated and depend on qualitative and quantitative characteristics of all criteria. A method of multiple criteria complex proportional evaluation of the projects discussed in this paper assumes direct and proportional dependence of significance and priority of investigated versions on a system of criteria adequately describing the alternatives and on values and significances of the criteria. The system of criteria is determined and the values and initial significances of criteria are calculated by experts. All this information can be corrected by interested parties (customer, users, etc) taking into consideration their pursued goals and existing capabilities. The degree of utility Nj of a building life cycle is directly associated with quantitative and conceptual information related to it. A degree of dwelling life cycle utility reflects the extent to which the goals pursued by the interested parties are attained. The paper concludes with a demonstrative example, concerning the multiple criteria assessment of plot, dwelling, contractor and maintenance alternatives, and dwelling life cycle variants are being developed based on these alternatives of solutions.

Criteria Weights

The environment in which the decision-making process takes place is often characterized by uncertainty and vagueness and, because of that, sometimes it is very hard to express the criteria weights with crisp numbers. Therefore, the application of the Grey System Theory, i.e., grey numbers, in this case, is very convenient when it comes to determination of the criteria weights with partially known information. Besides, the criteria weights have a significant role in the multiple criteria decision-making process. Many ordinary multiple criteria decision-making methods are adapted for using grey numbers, and this is the case in this article as well. A new grey extension of the certain multiple criteria decision-making methods for the determination of the criteria weights is proposed. Therefore, the article aims to propose a new extension of the Step-wise Weight Assessment Ratio Analysis (SWARA) and PIvot Pairwise Relative Criteria Importance Assessment (PIPRECIA) methods adapted for group decision-making. In the proposed approach, attitudes of decision-makers are transformed into grey group attitudes, which allows taking advantage of the benefit that grey numbers provide over crisp numbers. The main advantage of the proposed approach in relation to the use of crisp numbers is the ability to conduct different analyses, i.e., considering different scenarios, such as pessimistic, optimistic, and so on. By varying the value of the whitening coefficient, different weights of the criteria can be obtained, and it should be emphasized that this approach gives the same weights as in the case of crisp numbers when the whitening coefficient has a value of 0.5. In addition, in this approach, the grey number was formed based on the median value of collected responses because it better maintains the deviation from the normal distribution of the collected responses. The application of the proposed approach was considered through two numerical illustrations, based on which appropriate conclusions were drawn.
