A new approach to sustainable project scheduling for public institutions is proposed. The approach is based on experts’ opinions on three aspects of sustainability of project activities (human resources consumption, material consumption and negative influence on local communities), expressed by means of Z-fuzzy numbers. A fuzzy bicriterial optimization model is proposed, whose objective is to obtain a project schedule of an acceptable sustainability degree and of acceptable duration and cost. The model was inspired and is illustrated by a real-world infrastructure project, implemented in 2019 by a public institution in Poland.

Public projects are the projects implemented by public administration units and with the involvement of funds from the budget of this administration. Based on the literature analysis and the case studies of the completed public projects in different countries, it can be concluded that public projects do not always end on time and that many basic methods for project scheduling and task duration estimation are not used. Public projects have a significant impact on the future and consume huge amount of resources, thus their planning cannot be detached from sustainability principles. Therefore, there is a need to recognize scheduling of public projects as one of the key activities carried out by project managers and to develop appropriate methods in this area. In the paper we propose a procedure of scheduling public projects that allow to mitigate the scheduling problems and help in applying sustainability principles where the degree of sustainability is measured using fuzzy terms.

We present a novel, non-deterministic technique for global software project monitoring and re-scheduling that can be used by IT project managers to react on dynamically changing project conditions as the project knowledge grows and available resources are changed. The technique is adaptive, allows controlling overall risk level in each control step and makes advantage of the full PM Iron Triangle. We also shortly discuss the proposed technique in application to projects that are spread globally in different countries. The technique is verified on sample project data and its quality is assessed. What is more, we present the benefits and drawbacks of the proposed technique and consider suggestions for future work.

The research presented in the article concerns success and failure factors of infrastructure projects implemented by Polish local government units. Due to the fact that many of these types of projects fail, there is a need to search for the cause of their failure. One way to achieve this may be to identify critical success and failure factors. The paper contains a proposal of using fuzzy modeling to identify success and failure factors of infrastructure projects implemented by Polish local government units.
