This paper aims to develop an integrated Quality–Cost–Environmental (QCE) indicator for the selection of photovoltaic panels (PVps) offered to customers, considering the following criteria: (i) quality satisfaction; (ii) cost-effectiveness; and (iii) environmental impact throughout the life cycle. The proposed QCE indicator was developed within a framework that incorporated an FAHP (Fuzzy Analytic Hierarchy Process), cost-effectiveness analysis (CEA), and life cycle assessment (LCA). The model test confirmed its effectiveness in choosing a PVp which combines environmental friendliness throughout its entire life cycle with satisfactory quality and a reasonable purchase price for customers. The proposed model can be utilized by individuals, businesses, and public entities for the selection of high-quality, cost-efficient, and environmentally friendly PVps—thereby promoting sustainable development.

Purpose: The aim was improving the process of risk assessment occupational for industry, by implemented in this process the fuzzy scale (and the Fuzzy Analytic Hierarchy Process, 11 FAHP). Design/methodology/approach: The FAHP method was integrated with the PN-N-18002 method. Findings: It was demonstrated that implemented the FAHP method in PN-N-18002 method allows on more precise an assessment of the root of threats on the workplace. Research limitations/implications: This method can be used to risk assessment of each workplaces, by integrating the FAHP with any methods of occupational risk assessment. Practical implications: The assumption was to improve the method of risk assessment occupational for industry, in which as was shown the number of accidents in work was the highest. Test of the proposed method was carried out for the operator's position of a floating excavator KG-2.5 in one of Podkarpacie enterprise extracting aggregate. Social implications: This method can be helped to the entity performing the occupational risk assessment in precise identify the root of threats on the workplaces. This will ensure a safe workplace. Originality/value: The originality of the proposed method is to achieve more precise an assessment of the root of threats in the workplace than by using the traditional risk 27 assessment methods.
