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

Vol. 33, No. 4

133--154

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.

Data Envelopment Analysis (DEA) is a well-established, popular, and often used method for efficiency evaluation of units from all sector, both commercial and nonprofit organisations, of any scale of operations. Network DEA models are a relatively recent approach used to examine the efficiency of decision-making units (DMUs) having an internal structure of sub-processes. The article presents the concept of DEA network models in estimating the efficiency of courier and messenger companies with relations to their business clients. The considerations are supported by an example of data concerning leaders from the sector of couriers and messengers in Poland and one of the biggest and most popular online stores. The results are compared with the traditional DEA approach. In addition, to measure reliability for DEA scores, the jackknife procedure was performed. The author proves the usefulness of network DEA as a research and management tool.
