The quantitative multiple criteria decision making methods are practical to use in support systems. In this paper we analyse the and sensitivity analysis usage Both species of these strongly mathematically based. We take notice for initial data. Monte Carlo method is applied generation TOPSIS SAW presented paper.

Low-noise pavements are used as an effective method of traffic noise mitigation. reduce the that arises due to interactions between tires and road surfaces (tire/road) via implementation three main components: low pavement roughness, negative texture, a high air-void content. The tire/road reduction capabilities wearing layer vary depending on aggregate type, gradation, bitumen content, density. Consequently, demand for accurate prediction model has arisen from design asphalt mixtures. This...

The emerging more sophisticated computer hardware and software provide the users in various areas of activities with ample opportunity to use computer-aided systems. One type these systems includes decision support based on multiple attribute making methods. In designing such systems, question arises, which MADM methods is efficient should be used evaluating taking into account that best alternatives yielded by often differ. A great number researchers are trying answer other similar...

The paper provides a new synthesis method of multiple attribute decisions (SyMAD-3 – Synthesis Multiple Attribute Decisions using three methods) intended for combining multi-stage and into single common estimate. is applied selecting construction project on the basis its structural, technological safety decisions. To increase reliability decision, decision-making methods based quantitative measurements were to help person making decision monitor results relevant obtained employing same...

The authors of the present work offer developed model suggesting solutions to structural, technological and safety problems based on use a tree diagram as tool for decision analysis visualization. is aimed at integrating worked out in considered areas into single variant research object. A multi-stage reflecting set available combinations alternatives developed. branches are interlinked inherent relations between building structures, technologies safety. interaction interrelationship...

The article presents the results of analysis focused on effectiveness 4D CAD phenomenon which has been analysed by foreign scientists considering a number different aspects. conducted research differs from prior literature as objective, in our case, was to evaluate and justify using multi-criteria analysis. Effectiveness investigated through construction experiment observing group performances applying two types information – 2D drawings. Research findings have proved that efficiency model...

Daugiakriteriams sprendimo priėmimo uždaviniams spręsti taikant kiekybinius daugiatikslius metodus, dažniausiai neatsižvelgiama į galimas pradinių duomenų – rodiklių reikšmių paklaidas. Todėl neaišku, ar gautas sprendimas (alternatyvų išrikiavimas pagal racionalumą) nesikeis, jeigu keistųsi reikšmės (± n %, n< 50 %). Šiame straipsnyje, Monte Karlo modeliavimą, atliekama kiekybinių daugiatikslių metodų TOPISIS, SAW ir COPRAS jautrumo analizė. Jautrumo analizės pagrindas yra pasiskirstymas....

In the most multiple attribute decision making methods values are provided to transform into one dimension. The normalization of is not always needed, but it may be essential. This restructuring carried out in accordance with appropriate rules. It has been observed that some used for different practical calculations noted using rules same method produces alternatives priority line, data. Due fact this paper carry affect ranking alternatives, study. And find under what conditions change alternatives.

The performance and bearing capacity of the flexible pavement structure is ensured by providing necessary foundation comprised unbound granular material (UGM) layers subgrade. Whin this paper compaction level parameters deformation modulus relations determined for UGM subgrade in construction site. experimental data were tested applied standardized improved test methods, such as an alternative falling weight deflectometer (FWD) method with repetitive load, plate load tester, lightweight...

Surveying the condition of pavement is one most important processes in managing road network. The information collected during these surveys allows for calculation Pavement Condition Index, which a derivative cumulative qualitative indicator that evaluates various characteristics and defects. Deterioration modelling measured indicators calculated indices critical element its accurate prediction brings process management closer to higher quality by more efficiently allocating funds repair...

Daugelio socialinių, statybos investicinių, medicinos ir kitų sričių problemų sprendimui gali būti formuluojami daugiatiksliai sprendimo priėmimo uždaviniai. Dažnai tokie uždaviniai yra susijęs su neapibrėžtimi dėl įvairių priežasčių – tiek objektyvių, subjektyvių. Tuomet kyla klausimas, ar gautas sprendimas bus patikimas. Vieningos metodikos, skirtos daugiatikslių sprendimų patikimumui įvertinti pagal rodiklių reikšmingumus reikšmes, nagrinėtoje literatūroje neaprašyta. Minėtospriežastys...

The tasks of making the most appropriate decisions taking into account a number criteria are dealt with in variousfields such as engineering, industry, finance, economics and others. If aim is to arrange alternatives priority lineaccording quantitative attributes, then multiattribute decision-making methods suitable. Analysts using these usuallydo not take initial data errors – deviations attribute values, which case decision may be unreliable. In thisarticle, several statistical analysis...

The present article investigates the sensitivity of multiple criteria decision-making method TOPSIS in respectof attribute probability distributions. To carry out research, initial data – values were generated according to anormal, log-normal, uniform, and beta Decision matrixes constructed from data. Byapplying generated, result samples received. A statistical analysis was conductedfor results obtained, which revealed that distributions comply with resultsreceived by method. According most...

There is currently a wide range of computer-aided design (CAD) software systems available on the market, but there no methodology for selecting bestsuited one user, considering various evaluation criteria.Taking into account application multi-criteria decision-making methods in ranking and selection tasks, this paper proposes model suitability CAD preparation technical document, based an expert using AHP method.The proposed was realised through real situation analysis.The main advantage its...

In the most MADM (Multiple Attribute Decision Making) methods attribute values are provided to transform into one dimension.This restructuring is carried out in accordance with appropriate normalization techniques.It has been observed that some of used for different techniques.In practical calculations it was noted, using techniques same method, alternative priority lines, data, produced.Research object this paper group multiple decision making TOPSIS and COPRAS.The aim analyze influence...

In this paper we describe the application's fields of sensitivity analysis methods. We pass in review application these methods multiple criteria decision making, when initial data are numbers. formulate problem, which is more effective for usage making process.

Multiple criteria decision-making methods enable to choose the optimal decision, if his criterions is contradictorys. In herein paper describe MAUT – multiattribute utility theory. This method reasoned in up for indeterminations situations, but can use determinations situations. this multiple problem solvable with help of unitary functions.
