Project implementation scenario selection for sustainable project and product lifecycle management. Application of network data envelopment analysis

A method has been proposed to select one of several project implementation variants in the context of sustainable project management. The method should be applied in the phase of the project definition. The projects are viewed across the entire lifecycle of the project and its product. In all the phases, the sustainability aspects should be addressed in a balanced way. The sustainability context implies that different stakeholders will have conflicting opinions on the weights of different variables. The proposed approach is based on network Data Envelopment Analysis that does not require the weights of individual variables as input. Consequently, the proposed method is the first approach allowing users to select a project implementation variant in the context of sustainability and the entire project and product lifecycle, without imposing the weights of individual variables. The proposal is designed for organisations using project sustainable management.
