چکیده انگلیسی:
Nowadays, industrialization exposes the human and environment resources to serious dangers. The importance of these resources caused the HSE (health, safety and environment) to have a significant contribution in industries’ evaluation, especially in construction industry. While evaluating the project’s success from an HSE point of view, it is not enough to rely solely on the outputs without considering the impact of external factors affecting them. On the other hand, the variety of factors affecting HSE and their different kinds of interactions, forces us to use another aggregation operators rather than linear ones. Choquet integral (CI) is a well-known powerful aggregation operator to be used in such cases. There are different methods to define the coefficients of CI. One of the most recent and prominent methods is “the most representative capacity definition method”. This paper proposes a modification to this method by improving its entropy and consequently the reliability in, as named, non-reference projects evaluation. The modified algorithm is used in evaluating the impact of external factors on HSE performance of power plant construction projects. The results show the prominence of modified algorithm’s entropy compared to the original algorithm. Ultimately the external factors integrated score, which resembles the suitability of project’s environment, is compared with the score defined considering output results. According to results, in some projects there is a deep gap between score of HSE output result and aggregated score of external factors. The gap of two scores potentially figures the internal organizational factors performance.
