background: safety programs are a core part of safety management in workplaces that can reduce incidents and injuries. the aim of this study was to investigate the influence of safety training observation program (stop) technique as a behavior modification program on safety climate in a construction company . methods: this cross-sectional study was carried out on workers of the petrochemical co...
this paper presents a prediction model based on a new neuro-fuzzy algorithm for estimating time in construction projects. the output of the proposed prediction model, which is employed based on a locally linear neuro-fuzzy (llnf) model, is useful for assessing a project status at different time horizons. being trained by a locally linear model tree (lolimot) learning algorithm, the model is int...
The online observation of a construction site and processes bears significant advantage to all business sector. BIM is the combination of a 3D model of the project and a project-planning program which improves the project planning model by up to 6D (Adding Time, Cost and Material Information dimensions to the model). RFID technology is an appropriate information synchronization tool between the...
abstract project management in construction industry, in many cases, is imperfect with respect to the integration of occupational health and safety (ohs) risks. this imperfection exhibits itself as complications affecting the riskiness of industrial procedures and is illustrated usually by poor awareness of ohs within project teams. difficulties on ohs regularly came about in the construction i...
Abstract Project management in construction industry, in many cases, is imperfect with respect to the integration of Occupational Health and Safety (OHS) risks. This imperfection exhibits itself as complications affecting the riskiness of industrial procedures and is illustrated usually by poor awareness of OHS within project teams. Difficulties on OHS regularly came about in the construction i...
Objective: The aim of this paper is to propose a new approach to assess the aggregated impact of risks on the completion cost of a construction project. Such an aggregated impact includes the main impacts of risks as well as the impacts of interactions caused by dependencies among them. Methods: In this study, Monte Carlo simulation and Bayesian Networks methods are combined to present a frame...

Project management office (PMO) is a new emerging concept in Iranian construction industry. Executives expect this organizational unit to add value to the business, and meet the demands of stakeholders by performing specialized tasks ranging from providing project management support to portfolio management. In this regard, PMO managers have long faced the question of how to improve the performa...
Critical Success Factors (CSFs) are used to support and evaluate the success of a strategic and tactical approach in project implementation in order to increase the probability of success. This system is used by executors in project delivery to achieve improved performance capabilities with limited resources. The present paper aims to identify the impact of CSFs amongst the main elements involv...
due to the particular importance of projects in human life and in organizations, proper project management has been always regarded highly by researchers and practitioners. recent advances in technology and fundamental changes in most scientific areas have affected projects and made their nature and environmental circumstances much more complex than in the past. fortunately, in recent years, ma...
