“…eir model is aimed at selecting and scheduling projects based on time-dependent criteria as well as budget and resource constraints, solved via a hybrid multicriteria decision-making approach. All results they have obtained prove the effectiveness of their proposed strategy [12]. Outlining the importance of a proper contract in project management, Mahmoudi et al have conducted a research work, which suggests a comprehensive model for risk management in outsourced construction project contracts.…”

“…In addition, social aspects are another sector of the sustainable issue that affects projects performance. Traditional project selection has paid attention to just financial criteria and profitability without considering sustainability while, these days, many researchers have also considered sustainability in their studies since a combination of financial and sustainability criteria can trigger to enhance organizations' productivity and competitiveness and can affect project success and project management [12,19,22]. Duan et al have developed an integrated green supplier selection and order allocation (BSSOA) model to select appropriate suppliers along with the reasonable allocation of order quantities via a combination of linguistic Znumbers and the alternative queuing method (AQM) together with the multiobjective line programming (MOLP) model.…”

According to the heavy reliance of economic growth on environmental and social matters, sustainable development has turned into one of the main strategies of the organizations associated with selecting the project basket. Moreover, market conditions, rapid global changes in several aspects, uncertainty in intellectual judgments of the experts, and many other factors have increased uncertainty in problems of this kind. Accordingly, the main objective of this paper is to develop a mixed decision-making approach (DEMATEL-VIKOR) with the aim of ranking and evaluating suggested projects considering sustainability indices in a “mass production and infrastructural” company under uncertainty, while also taking reliability (Z-number information) into account. Given the existing uncertainty in the opinions of experts and previous data, fuzzy approach and Z-number information have been employed for weighting the filtered sustainability indices that are aligned with the objectives of the considered company (Z-DEMATEL), as well as ranking candidate projects (Z-VIKOR), which contribute to the main innovation of the present research. In addition, for scoring in the Z-number state, a novel definition of linguistic variable (fuzzy linguistic variable considering probabilities) has been put forward. The suggested approach was solved by an expert in two numerical examples in three certain, fuzzy, and Z-number scenarios, the results of which show that different results are obtained for different scenarios. Apart from that, given that Z-number takes the probability of reliance on the opinions of experts into consideration, the more the approach moves from being certain towards the fuzzy state and the Z-number state, the more the results approach the real world, hence yielding more reliable results. Therefore, results obtained from the proposed Z-DEMATEL-VIKOR approach are far more reliable. Moreover, significance weights in the Z-number scenario are 39%, 26%, and 36% in the economic, social, and environmental dimensions, respectively, which is indicative of the importance of social and environmental aspects apart from the economic dimension.

In this study, the problem of project selection and scheduling with resource management is considered project setup times, dynamic project arrivals, priorities and relationship between projects. A fuzzy multi-objective mixed integer linear programming (MILP) model is proposed for the solution of the problem. The classic two-phase fuzzy goal programming (FGP) approach is modified to solve the proposed multi-objective MILP model. The addressed problem is defined over the project selection and scheduling problem of a construction company. The effect of resource management on the project selection and scheduling problem is demonstrated over the generated test problems. Modified two-phase FGP and classic two-phase FGP approaches are compared over test problems. With the use of the modified two-phase FGP approach, additional alternative solutions are found for the problem.

“…In the closing phase, a major emphasis is also given to the sustainability of the project. More and more organizations today pay great attention to the criteria characteristic of sustainability, in addition to the financial ones (RezaHoseini, Ghannadpour, & Hemmati, 2020). Sustainability considers the way of continuing the activities of the project and implicitly of its effects, after the completion of its implementation, respectively all the measures applied within the project to ensure that the benefits of the target group will be guaranteed in the future.…”

The closing processes of the projects influenced their performance from the perspective of how the transfer of competences and resources was managed between the different categories involved. The focus of the efforts of the project teams on the processes of beginning and developing the projects generates a weaker involvement in the closing of the projects, and this aspect is frequently to the disadvantage of the beneficiaries. The present research paper is a systematic review and aims to highlight the need for an integrated approach to the processes of project completion, in the context of the sustainability requirements imposed by the owners. The obtained results can give a complete image to the future project managers who can thus know the particularities of the closing processes, even from the testing and acceptance phase.
