A Fuzzy Model to Determine Construction Firm Strategies
Aynur Kazaz,Bayram Er,Burcu Ezgi Ozdemir 대한토목학회 2014 KSCE JOURNAL OF CIVIL ENGINEERING Vol.18 No.7
The construction industry has a complex and dynamic environment. It consists different professions and is intertwined with other industries. This results in construction firms as very sensitive to both internal and external factors. Correct strategies should be chosen and used effectively to reduce the impact of these factors or benefit from them. In this paper, a methodology for determining proper strategies was introduced. For this purpose in the first part of the study, 50 large-scaled construction firms in Turkey were examined by a Strengths, Weaknesses, Opportunities and Threats (SWOT) analysis. In addition, each firm’s primary goal was also identified. The results obtained in the first part were used to develop a fuzzy model for determining main objectives of construction firms. The validity of the model was confirmed by testing real data of the surveyed firms. Finally, relevant strategies in accordance with the firms’ main goal were introduced. The results of the questionnaire revealed that there is high correlation between the firms’ current positions in the market and their main goals. In addition, construction firms can also be classified according to Miles and Snows’ strategy typology.

Background: Pectus excavatum (PE) and pectus carinatum (PC) are the most common chest wall deformities. In this study, we aimed to characterize how patients obtained information about these deformities, as well as patients’ family history, associated medical problems, and postoperative satisfaction after the Nuss and Abramson procedures. Methods: This cross-sectional retrospective study included patients who were operated by a single surgeon between 2006 and 2013. Follow-up calls were made after approval of our institution’s ethics committee. We reached 207 of the 336 PE patients (61.6%) and 73 of the 96 PC patients (76%). Results: The majority of the patients were male (85% of the PE patients and 91.8% of the PC patients). The age of diagnosis of PE was 14.52±0.51 years and the age at the time of operation was 17.89±0.42 years; for PC patients, the corresponding ages were 15.23±0.55 years and 16.77±0.55 years, respectively. A total of 70% of the PE patients and 63.8% of the PC patients obtained information about pectus deformities through the Internet. In 27.1% of the PE patients with an associated anomaly, 57.1% (n=13) had scoliosis, while 41.1% of the PC patients with an associated anomaly had kyphosis (n=5). Postoperative satisfaction, as evaluated on a scale from 0 to 10, was 8.17±0.15 for PE patients and 8.37±0.26 for PC patients. The postoperative pain duration was 51.93±5.18 days for PE patients and 38.5±6.88 days for PC patients. Conclusion: In this study, we found that most patients with pectus deformities were male. The Internet was an important resource for patients to learn about their deformities. Family history and associated anomalies were identified as important aspects for consideration in the clinical setting. The patients reported high levels of postoperative satisfaction, and pain management was found to be one of the most important elements of postoperative care.
