به علت طبیعت ناهمگن زمین و وجود عدم قطعیت در داده¬های اولیه طراحی، پروژه¬های تونلسازی در همه قسمت های درگیر در پروژه تحت تأثیر ریسک قرار می¬گیرند. در طراحی الگوی نگهداری تونل، تعیین پارامترها به صورت کمی مشکل است، همچنین اگر این پارامترها از دقت کافی برخوردار نباشند، ریسک¬های غیرمنتظره ای، همچون کاهش پایداری تونل یا خسارات اقتصادی ناشی از میزان بیش از اندازه نگهداری ها رخ می دهد. در این تحقیق ر...

Preliminary work on the development of measures appropriate for the safety domain is reported. Measures are expressed in the style of the Practical Software and Systems Measurement (PSM) approach, a programme sponsored by the US DoD. Proposed measures are integrated with the PSM measurement framework. Reported work has been informed by discussions within the PSM community and by concurrent work...
This study described the development of a safety climate instrument for employees at three mini-steel mill locations in the U.S. The instrument was validated by structural equation modeling using AMOS and measured safety climate at a specific “point in time” to assess the safety culture of the industry. The Hall Safety Climate Instrument was developed using a three-construct theoretical framewo...
Safety cases offer a means for communicating information about the system safety among the system stakeholders. Recently, the requirement for a safety case has been considered by regulators for safety-critical systems. Adopting safety cases is necessarily dependent on the value added for regulatory authorities. In this work, we outline a structured approach for assessing the level of sufficienc...
Background and aims: Construction is one of the most dangerous industries in the worldwide. Workplace safety is a complicated phenomena and behavioral safety in the construction industry is even more so. The Aim of this study was the development of a new model for understanding the factors influencing unsafe behavior in construction industry. Methods: In the current quantitative study, a three-...
Background: approximately 90 percent of workplace accidents are due to unsafe behaviors and human errors. Identification of the factors influencing unsafe behaviors in the prevention of these accidents is useful. The aim of the present study was to assess the relationship between dimensions of safety climate and safe behaviors in a petrochemical industry. Methods: In this descriptive – correla...
Background: An important factor in the prevention of industrial accidents is the ability of employees to maintain awareness of the work situation, understand the information it holds, and predict how situations will develop. In the present study, we examined the role of fatalistic beliefs and safety climate in predicting occupational situation awareness (SA) among workers. Mate...
BACKGROUND A supportive patient safety culture is considered to be an essential condition for improving patient safety. Assessing the current safety culture in general practice may be a first step to target improvements. To that end, we studied internal consistency and construct validity of a safety culture questionnaire for general practice (SCOPE) which was derived from a comparable questionn...
