AHP and CBA Application to Layout Design: A Case of Classroom Layout Assessment

03 Jul 2019-pp 1333-1344
TL;DR: The findings from the study indicate that CBA aids in defining a robust set of design criteria, sub-criteria and attributes and facilitates a collaborative decision-making process and on the other hand, AHP provides a structured approach for eliciting individual participant judgments.
Abstract: Arriving at a consensus in design decisions is challenging owing to the presence of diverse and multidisciplinary stakeholders with multiple design objectives. The literature on AEC design decision making have reported Analytic Hierarchy Process and Choosing by Advantages as two commonly used multi-criteria decision-making techniques for evaluation of design alternatives. However, the existing literature has mainly focused on choosing between material or technology and the comparison of the two techniques to assess the suitability for their application to non-spatial aspects of AEC design problem. The current work seeks to investigate the suitability of CBA and AHP to a layout design problem. A decision-making exercise involving a hypothetical case of evaluation of three classroom layouts was conducted. A set of criteria for design evaluation which was derived based on a previous study on stakeholder design values was used in the exercise. Conclusions were drawn based on the operationalization of the two techniques rather than a direct comparison of the results obtained from the two techniques. The findings from the study indicate that CBA aids in defining a robust set of design criteria, sub-criteria and attributes and facilitates a collaborative decision-making process. On the other hand, AHP provides a structured approach for eliciting individual participant judgments. The benefits and limitations with respect to the operationalization of the two techniques are discussed in detail.

TL;DR: In this paper , the authors present a study applying the Choosing By Advantages (CBA) Tabular method for the hiring process of a new team member, aligning the structure of the selection process with the five phases of the CBA system.
Abstract: Construction projects rely on the people in the project team; people are selected to perform their role satisfactorily in the project and contribute to its success. However, the selection in the hiring process has different biases that are often not perceived by those who decide to hire people. This research aims to present a study applying the Choosing By Advantages (CBA) Tabular method for the hiring process of a new team member, aligning the structure of the selection process with the five phases of the CBA system. The selection process is divided into two parts to reduce bias in decision-making: the first preliminary part uses information associated with objective data from the applicants' CVs without knowing their identities. The second part complements information knowing their identities obtained from personal interviews. In this research, we use a practical approach called the SEEDS Model®, represented in five categories of biases present in everyday thinking (similarity, expedience, experience, distance, and safety). Furthermore, the results demonstrate that CBA and SEEDS Model® help reduce bias in the selection process and choose people for their attributes representing their capacities, avoiding bias in the selection.

TL;DR: Choosing by advantages (CBA) is a new generation decision-making method utilized mainly in lean construction, sustainable design, methods and materials selections for the last two decades as discussed by the authors .
Abstract: Choosing by Advantages (CBA) is a new generation decision-making method utilized mainly in lean construction, sustainable design, methods and materials selections for the last two decades. The value-based approach of CBA considers cost as a constraint and uses the advantages of the decision alternatives for preference, choice, and ranking. This approach can benefit facilities management (FM) processes that are challenged with cost and budget dominance in decision-making. This study conducted a comprehensive literature review about CBA revealing the benefits of and areas for improvement in the method while also investigating the possible application areas of CBA in FM practices. The review covered 67 relevant studies in the CBA topic area over the last two decades and identified the research clusters of these articles, focusing on studies that utilized CBA beyond the scope of Lean Construction. Moreover, the review revealed areas for improvement of CBA, such as the lack of structure in the Importance of Advance (IoA) scale, minimizing bias in stakeholder consensus, and considering weights and/or prioritization in decision factors. In addition to increasing awareness of the CBA method, this study identified areas where CBA has the potential to benefit; building maintenance decision-making, capital project planning, prioritization, procurement, buy vs. lease analysis, lease type and site selection, and resource and personnel allocation in FM practices.

TL;DR: In this paper , the authors present a synthesis of set-based design's benefits, difficulties, and trends in construction projects and show a trend towards adopting the SBD technique for the design of structural elements of buildings and bridges.
Abstract: Design processes generate inputs to plan and control the development of project construction processes. There is a growing interest in implementing design techniques involving various options to reach a systemic overview and select the best proposal. One such technique is Set-Based Design (SBD) which identifies and explores multiple design options simultaneously. Although several studies have been carried out focused on the SBD implementation in construction projects, there need to be more studies that synthesize the main findings to facilitate a proper implementation according to the different contexts. Considering this gap, this paper focuses on presenting a synthesis of SBD's benefits, difficulties, and trends in construction projects. The research method corresponds to a systematic literature review of a sample of 281 documents initially drawn from Scopus database and finally, with 32 documents screened, this study undertook the following stages. The research method has five stages: 1) scope definition; 2) searching of relevant documents; 3) document selection; 4) evidence collection, analysis, and synthesis; and 5) results report. The findings show a trend towards adopting the SBD technique for the design of structural elements of buildings and bridges. The three most frequently reported benefits of SBD adoption are: 1) transparent decision-making processes, 2) better collaboration in decision-making, and 3) better communication among designers. The three most frequently reported difficulties 1) inadequate organizational structure for the adoption of SBD, 2) lack of staff experience, 3) resistance to change in organizations.

TL;DR: The TFV-teoriaksi (Transformation, flow, value generation) as discussed by the authors is a well-known method for value generation in the literature, e.g. in finance.
Abstract: Vaitoskirja pyrkii vastaamaan kahteen kysymykseen: Onko mahdollista muotoilla tuotannon teoriaa? Jos on, johtaako teoria tehokkuuden kohoamiseen, kun sita sovelletaan rakentamiseen? Historiallinen analyysi paljastaa, etta 1900-luvulla on kehitetty ja sovellettu kolmea eri tuotannon kasitteellista mallia. Tuotanto on nahty muunnoksena, virtana ja arvontuottona. Kaikkia naita malleja voidaan perustellusti pitaa valttamattomina tuotannon ymmartamiseksi, ja niita tulisi siten soveltaa rinnakkain. Vaitostutkimuksessa esitettavaa tuotannon mallia kutsutaan tuotannon TFV-teoriaksi (Transformation, Flow, Value generation). Tutkimuksen tulokset osoittavat, etta tehokkuutta alentavia ongelmia esiintyy yleisesti rakentamisen kaikissa vaiheissa: rakennuttajan paatoksenteossa, suunnittelun ohjauksessa ja rakennustuotannon ohjauksessa. TFV-teoria selittaa suurelta osin rakentamisen ongelmien syntymisen. Tarkasteltaessa pioneeriyritysten kehittamishankkeita, joissa on sovellettu TFV-teorian tiettyja ydinpiirteita, voidaan havaita, etta talle teorialle perustuvat menetelmat tuottavat merkittavia kustannussaastoja ja muita hyotyja. TFV-teorian avulla voidaan siten suunnata uusiin tehokkaampiin menetelmiin tahtaavaa kokeilua ja kehitystyota seka rakentamisen kaytannon etta tutkimuksen piirissa.

TL;DR: In this paper, a selection model based on analytic hierarchy process (AHP), a multi-attribute decision analysis method, is presented to provide solutions for systematic evaluation of soft factors, and the weighting of soft benefits in comparison with costs.
Abstract: Selection of equipment for construction projects, a key factor in the success of the project, is a complex process. Current models offered by the literature fail to provide adequate solutions for two major issues: the systematic evaluation of soft factors, and the weighting of soft benefits in comparison with costs. This paper presents a selection model based on analytic hierarchy process (AHP), a multiattribute decision analysis method, with a view to providing solutions for these two issues. The model has the capacity to handle a great number of different criteria in a way that truly reflects the complex reality, to incorporate the context and unique conditions of the project, and to allow for manifestation of user experience and subjective perception. The model was implemented in an in-house developed system that was improved and validated through testing by senior professionals. The main academic contribution of the study is in the modification of AHP to correspond with the nature of equipment selection and in its utilization as an effective means for the formalization of knowledge possessed by competent, experienced practitioners. On the practical side, the proposed model offers an efficient, convenient tool that forces the users into orderly, methodical thinking, guides them in making logical, consistent decisions, and provides a facility for all necessary computations.
