Models of indicator systems of construction contraction agreements

Abstract

A number of multicriteria decisions must be made during construction investment processes. A number of support systems for multicriteria tasks of construction investment processes are available. A part of them is reviewed in this article. Effectiveness of the construction investment process is greatly influenced by an appropriate formulation of a construction contraction agreement (CCA). In order to formulate the effective contraction agreements, multicriteria techniques for evaluating and comparing CCAs must be created. Besides technical, organisational and economic aspects of construction, legal aspects of a CCA must be also analysed in order to prepare such techniques. Therefore, legal decision making systems are also reviewed in the article. A conclusion can be made from the review that legal decision making systems for CCAs are not available currently. One of the main tasks in the creation of multicriteria support systems is the formation of a multicriteria indicator system. Three models of multicriteria indicator systems of CCAs are analysed in the article, and the best model for creating multicriteria evaluation technique is determined. On the basis of this model, significance of indicators should be determined and a multicriteria decision support system should be created in further research stages.

Santrauka

Investicinio statybos proceso metu reikia priimti nemažai daugiakriteriu sprendimu. Yra sukurta daug statybos paramos sistemu daugiakriteriams uždaviniams spresti statybos investiciniame procese. Dalis iš ju apžvelgta straipsnyje. Statybos investicinio proceso efektyvumui labai svarbus tinkamas statybos rangos sutarties sudarymas. Siekiant sudaryti efektyvias statybos rangos sutartis, reikia sukurti daugiakriteres statybos rangos sutarčiu ivertinimo ir palyginimo metodikas. Siekiant parengti tokias metodikas, reikia išnagrineti ne tik statybos techninius, organizacinius, ekonominius, bet ir teisinius statybos rangos sutarties aspektus. Todel straipsnyje pateikta ir teisiniu sprendimu priemimo sistemu apžvalga. Iš šios apžvalgos taip pat darytina išvada, kad šiuo metu nera statybos rangos sutarties teisiniu sprendimu paramos sistemu. Vienas iš pagrindiniu uždaviniu kuriant daugiakriteres paramos sistemas yra daugiakriteriu rodikliu sistemos nustatymas. Straipsnyje nagrinejami trys daugiakriteriu statybos rangos sutarties rodikliu sistemos modeliai ir nustatytas geriausiai daugiakriterio ivertinimo metodikai kurti tinkantis modelis. Remiantis šiuo modeliu tolesniuose tyrimo etapuose turetu būti nustatomi rodikliu reikšmingumai ir kuriama daugiakritere sprendimu paramos sistema.
