Selection of the effective dwelling house walls by applying attributes values determined at intervals

Abstract The higher life quality standards, the changes of habits and new well‐being requirements have led to an increase in the demand for housing. Decision‐making problems in construction management often involve a complex decision‐making process in which multiple requirements and conditions have to be taken into consideration simultaneously. However, not every attribute used in multidimensional scaling is equally and precisely weighted in the real world. Thus quantitative and qualitative assessments are often required to deal with uncertainty, subjective and imprecise data. The accuracy of performance measures in common multi‐attribute methods is usually assumed to be accurate. Grey theory is a new technique for performing prediction, relational analysis and decision‐making in many areas. This paper considers the application of grey relations methodology for defining the utility of an alternative and is proposed as a method of multiple criteria COmplex PRoportional Assessment of alternatives with Grey ...

Multicriteria selection of project managers by applying grey criteria

Abstract There is a number of criteria and associated sub‐criteria influencing the match of managers to construction projects. Criteria and sub‐criteria were identified based on a thorough review of the related literature and interviews of management personnel involved in the project managers selection. Project managers characteristics are considered to be less important for an effective project management. The model is based on multicriteria evaluation of project managers. The evaluation embraces the identified criteria influencing the process of construction project manager selection. This paper considers the application of grey relations methodology to defining the utility of alternatives, and offers a multiple criteria method of Complex Proportional Assessment of alternatives with grey relations (COPRAS‐G) for analysis. In this model, the parameters of the alternatives are determined by the grey relational grade and expressed in terms of intervals. A case study presents the selection of construction p...

Contractor selection of construction in a competitive environment

Contractor selection is a vital part of the project management cycle and deals with risk and risk management. This paper presents contractors’ assessment and selection based on the multi‐attribute methods in a competitive and risky environment. The model is based on a multi‐attribute evaluation of contractors, the determination of their optimality criterion values according to Hodges‐Lehmann rule. The proposed model could be applied to assessment of construction operations. The attributes of contractor evaluation are selected taking into consideration the interests and goals of the stakeholders as well as factors that influence the process of construction efficiency. The model is based on metric scores. A background and a description of the proposed model are provided and a few key findings from the data analyses are presented.

Selection of construction enterprises management strategy based on the SWOT and multi-criteria analysis

The paper proposes a methodology for determining management strategies in construction enterprises. For this purpose, the SWOT (Strengths, Weaknesses, Opportunities and Threats) analysis as an instrument for formulating management strategies is recommended. The best practices for this reason are also analysed. The algorithm helps to select the most preferable strategies based on the AHP, expert judgment and permutation method of feasible alternatives. A perspective of construction enterprises management regarding the SWOT is carried out on a basis of selected description of the current state and the feasible future alternatives. Finally, the selected alternatives are ranked according to the permutation method of feasible alternatives. The case study shows the applicability of the proposed model to the real management problems solution.

Professor Edmundas Kazimieras Zavadskas: His Academic Research, School Of Thought, And Most Eminent Results Of His Work

Multiple Criteria Decision Making (MCDM) substantially evolved during the past decades and became one of the most important areas in Operational Research in Civil Engineering and Management Science. In Europe, this area is closely related to research performed by Professor Edmundas Kazimieras Zavadskas. The paper presents a review of extensive scientifi c work of Professor E.K. Zavadskas on the occasion of his 70th birthday. The paper also highlights his research carrier, and lists some of his fi elds of activity and research results including monographs, books, prized publications, memberships in various associations and other areas.
