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.

Port approach for merchant ships (regarding docking) is a special event related to the safety of ships and port facilities. This maneuvre is for emergency situations, and the consequences can be very damaging because there is a high risk of occurrence and severity can be high. In Algeria, 90% of foreign trade depends on shipping, and commercial vessels must dock in the port safely. This study aims to contribute to the management of risks associated with port operations by designing a matrix for specific assessment of this type of risk based on analysis of several incidents and accidents regarding maneuvring ships in Algerian ports. The design of the evaluation matrix of risks associated with port operations in Algeria is done in the context of the application of the Formal Safety Assessment methodology for improved performance of this method regarding precision and accuracy of results.

This paper deals with load side management strategy for (photovoltaic–wind–diesel) hybrid system for medium rural health building located in the Sahara region. The paper presents an overview about geographic and climate data of the location and develops a typical load profile of electrical energy, depending on a real investigation of daily electricity consumption. The base of the proposed management strategy is the control of the air conditioning system and the non-critical lighting of the building as they consume more than 50% of the total power consumption. The result shows that the reduction in the peak consumption is about 20% using the proposed management strategy, which has significant economical, technical, and environmental benefits
