Purpose The purpose of this paper is to deal with the allocation requirements of the dependability of the multiphase systems. Design/methodology/approach It consists of a proposal for a combined methodology based on the simultaneous use of decomposition systems and reliability allocation method. Findings In the developed methodology, the authors use the principles of risk assessment and propose a new formulation of weight allowance with reference to the structural‒functional dependence. Practical implications The suggested methodology provides invaluable help to implementation process analysis. Originality/value The adopted allocation approach is based on the use of a three-dimensional model: temporal, structural and functional decomposition of systems.

“…Furthermore, note that a preventive measure has, over time, some effects that are materialized by the avoided damages thanks to this measure. In order to take into account the scaling of these avoided damages, we actualize them with the use of the following Equation (Mellal and Djebabra, 2015):…”

Purpose The purpose of this paper is to valorize the contribution of the cost-benefit analysis (CBA) method in the evaluation of the prevention measures of forest fires. Design/methodology/approach The suggested approach is based on the economic analysis of the forest fires’ risks using the CBA which has become inevitable in risk analysis’ domain. Findings The suggested approach shows the interest of the CBA method in the sense that each reduction measure of the forest fires’ risk eliminates the potential damages and, therefore, it is likely to generate benefits for the company in terms of avoided damages on the territory that is concerned by these measures. Practical implications It consists in comparing on time, the benefit generated by a reduction measure of a forest fires’ risk and its implementation cost. This comparison gives an important focus on the economic relevance of such a reduction measure of forest fires’ risk. Originality/value The question is to highlight the importance of both: the investment in terms of forest fires and the allocation of this investment on various preventive measures of forest fires.

“…With the development of decision analysis techniques, the application of ERA has widened since the late of 1980s to provide scientific evidence for environmental management (Eduljee, 2000). For example, risk evaluation based on Benefit-Cost Analysis (Mellal and Djebabra, 2014), and comparative risk assessment based on methods of indicators selection (Diakaki et al, 2006) or on methods of Multi-Criteria Decision Analysis ( Jafar et al, 2013).…”

Purpose – This paper is interested to assist organizations in the task of selecting and use appropriate indicators for their environmental evaluation procedure (EPE). This maximizes the successful deployment of the EPE process and as a consequence the introduction of good environmental practices. The paper aims to discuss these issues. Design/methodology/approach – It consists of a proposal for a combined methodology based on the simultaneous use of environmental risk (ER) approach and RPN-based allocation method. Findings – In the developed methodology, the authors use the principles of risk assessment and purpose a new formulation of weight allowance with reference to the severity of ERs and significance of environmental aspects. Practical implications – Methodology suggested constitutes an invaluable help to implementation EPE process and as a consequence the introduction of good environmental practices. Originality/value – Methodology suggested facilitates the process of environmental performance evaluation providing substantial assistance to one of the most important stages that is to decide which particular indicators will be considered.
