    Design Team Effectiveness and Architects' Personality Types
    (Emerald Group Publishing Ltd, 2026) Alan, Ece; Arditi, David; Gunaydin, Husnu Murat; Akcay, Emre Caner
    PurposeThe personalities of the design team members constitute one of the factors that influence team effectiveness. In this study, 223 members of the "American Institute of Architects" who are employed by the largest architectural design firms in the United States of America were categorized according to their personality types by using "The Enneagram Personality Type Model." Also, the respondents' opinions about eight team effectiveness outcomes were recorded in order to explore the relationship between team members' personality types and team effectiveness outcomes.Design/methodology/approachThe information was collected by a questionnaire where the first part included 144 pairs of statements that were used to identify respondents' personality types. The second part sought designers' opinions about the importance of eight team effectiveness outcomes rated on a Likert scale ranging from 1 to 5. The results were assessed by performing the Kruskal-Wallis test first and Dunn's post-hoc test with Bonferroni adjustment subsequently.FindingsThe findings highlight the significance of personality types in effective design teams. While Type 6 (loyalist and skeptic) and Type 3 (achiever and performer) architects prioritize team effectiveness the most, Type 7 architects (enthusiasts and epicureans) assign the lowest importance. However, the presence of Type 1 (reformist and perfectionist) and Type 8 (challenger and protector) architects within the same design team may involve challenges or conflicts.Originality/valueThe primary contribution of this study is that it is the first study in the construction management literature that utilizes The Enneagram of Personality Test to understand the relationship between team members' personality types and team effectiveness outcomes. This study is of direct relevance to practitioners and could be utilized in design team-building activities.

    Prioritization of Risk Events in Ppp Wind Power Projects Using Integrated Fmea and Monte Carlo Simulation
    (2021) Akçay, Emre Caner
    The popularity of public private partnership (PPP) projects has grown all over the world, especially indeveloping countries. The success of PPP projects heavily depends on how effectively risk assessments areperformed. Failure Mode and Effects Analysis (FMEA) enables risk assessment by considering the impact,the probability, and the detection rate of risk events. However, it is very difficult to predict a single value forthese variables. The objective of this research is to integrate FMEA and Monte Carlo simulation, and to usethis model to perform risk assessment and prioritization of risks in PPP projects. The proposed model wasapplied to a real wind power generation investment located in the Aegean region of Turkey. The top threeimportant risk events are “unfavorable wind speed”, “fluctuation in exchange rates”, and “interest ratevolatility”. The model perfumed to the satisfaction of experts. The primary contributions of this researchinclude (1) a method that allows the identification of the risk events in PPP projects; (2) a model that performsrisk assessment and prioritization of risk events in PPP projects; (3) an integrated FMEA and Monte Carlosimulation model that performs stochastic risk assessment in PPP projects. Both public agencies and privateconsortia should benefit from the proposed model.

    Yeşil Binalar için Analitik Ağ Süreci (aas) Kullanılarak Yüklenici Seçimi
    (2020) Akçay, Emre Caner
    Binalar, dünyadaki tükenebilen kaynakların azalmasında ve enerji tüketiminde önemli bir paya sahiptir. Buçevresel etkileri en aza indirmek için yeşil binalar dünyada giderek önem kazanmaya başlamıştır. Yeşil binalarıngiderek önem kazandığı ve sayısının her geçen gün arttığı ülkelerden birisi de Türkiye’dir. Yeşil bina yaptırmakisteyen yatırımcıların en önemli sorunlarından biri, yeşil bina inşaatını yapacak olan yüklenici firmanın seçimidir.Bu çalışmada çok kriterli seçim yöntemlerinden biri olan Analitik Ağ Süreci (AAS) kullanılarak yeşil binalar içinyüklenici seçim modeli oluşturulması hedeflenmiştir. Buna göre, önce kavramsal bir model geliştirilmiş dahasonra AAS kullanılarak önerilen modelin pratikte nasıl uygulanabileceği Ankara’da gerçekleştirilmesi planlananbir yeşil bina projesinde gösterilmiştir. Oluşturulan bu modelin yeşil binalar için yüklenici seçimi yapanyatırımcılara yardımcı olacağı düşünülmektedir.
