This paper presents an application developed to visualize and edit Activity-On-Arc (AoA) project networks. It is part of a larger project that has the goal to study the resource allocation problem in stochastic multimodal activity networks. This application was developed in Java programming language and uses the open source libraries JGraph and JGrapht. It enables one to visualize and edit AoA networks with multiple resources, and save them into one of the two types of files available (TXT or XML).

A Systematic Literature Review (SLR) on the Resource-Constrained Multi-Project Scheduling Problem (RCMPSP), Uncertainty, and Resource Flexibility (human resource) is presented in this study. The main purpose is to help scholars with an overview of existing techniques and to identify new research directions. After applying exclusion criteria, 107 papers were analysed (2013-2023). The methodology adopted for this SRL is PRISMA. Based on the results, the approaches proposed to solve the RCMPSP were classified and the main findings were presented. The results show that the main focus of the existing research has been devoted to approximate algorithms. Genetic algorithms (GAs) and priority rules (PRs) are the most representative approximate algorithms, with 39% and 18%, respectively. At the same time, mixed integer programming (MIP) (9%) and branch & bound (B&B) algorithms (4%) are the most used exact algorithms. This analysis provides a vivid roadmap for future research based on the collected papers.

The Portuguese Project Management Observatory (PPMO), an initiative of the Portuguese Association of Project Management (APOGEP), is being developed by the University of Minho in partnership with other Higher Education institutions. The main objective of this research was to study the status of project management in Portugal, namely which tools and techniques are most and least used by organizations, the profile of Portuguese project managers, the methodologies used, accomplishment of project indicators and sustainability practices. It was also an objective to compare the results found with a similar study done a year before. The method selected for this study was a survey applied through an online questionnaire directed to Portuguese organizations. The results show that the most used tools and techniques are Activity List, Kick-off Meeting and Gantt Chart; and the least used are Decision Tree, Value Chain and Cost Life Cycle Analysis. As expected, significant differences were found in the income of project managers, when considering variables such as gender, age, current position, education level, and activity sector. Hybrid methodologies are used in a large part of the respondents' organizations. Although some changes were verified between 2021 and 2022, there are no significant changes reported.
The methodology of project management has been widespread in organizations of different functions and sizes. In this context, we address the issue of optimal resource allocation, and more specifically, the analysis of complementarity of resources (primary resource and supportive resource) in a project. We develop a conceptual system capable of determining the ideal timing, and the ideal mixture of resources allocated to the activities of a project, such that the project is completed on time, if not earlier, with minimal cost.
The project management field has shown great progress over the last decades. With technology evolution, project managers as well as other managers have a faster and more efficient way to handle information. While progress brought more abilities to managers, it also brought them more requirements, and an increasingly higher level of minimum accepted quality. The development and usage of new scheduling techniques became therefore imperative, so that better results could be achieved. In this research, four scheduling techniques well documented in the literature were studied: Early Start Schedule, Late Start Schedule, Constructive Heuristics and Branch-and-Bound. The main objective of this research project was to integrate these scheduling techniques into commercially available software, in order to help project managers deal with scheduling tasks in a more easy and controlled way. These scheduling techniques were integrated as an add-in, coded with C# programming language, for Microsoft Project 2010. After developing the add-in, an experimental phase was performed, in which the software was tested using some example projects. The initial hypothesis was confirmed by the results. For the tested projects the conclusion was that it was possible to get better results, concerning the project’s duration, using the studied techniques rather than the default scheduling technique used by Microsoft Project 2010.
This paper aims to present a systematic literature review that discusses the importance of Stakeholder Management (SM) and Communication Management (CM) for Non-Governmental Organizations (NGOs). Through a systematic search in three databases, 35 studies were identified that met the inclusion criteria and addressed the area of SM and CM, focusing on the perception of the influence of CM on stakeholder engagement and satisfaction of their needs, as a Critical Success Factor (CSF) for project success. A mapping of the findings is also presented. Additionally, the limitations found in the literature were discussed and possibilities for future research are proposed. The study emphasizes the relevance of SM and CM for the success of NGO projects and highlights the need for more strategic and integrated approaches to managing these factors. Thus, this article contributes to the debate on SM and CM in NGO projects, offering effective practices for the successful management of these CSF.

The expansion of textile and clothing production to Asian regions has both, increased competition and created a need for integration with the textile and clothing global supply chain. Strategies are being designed to improve competitiveness and responsiveness of the chains with increasing diversification of products. This study examines the potential of different strategies formulated by experts with focus on Pakistan s case, developed by brain storming sessions with external experts, composed from a chain s internal-view and based on existing strengths and weaknesses in the chain using a SWOT analysis. The aim of this previous study was to identify internal and external factors relevant to textile and clothing supply chain in Pakistan. These factors played an important role in the development of strategies which are useful for improving the competitiveness of the chain. In future it is our intention to formulate our decision structure based on external view of the chain and with more generalized criteria. This kind of structure produces the view which is usual in supply chain competitive scenarios. Here the criteria were viewed internally and the problem was formulated based on SWOT factors. Thus, using inputs from our previous work, “SWOT Analysis of Pakistan Textile Supply Chain”, we evaluated the strategies developed for achieving competitiveness in textile and clothing supply chain in Pakistan and their potential effects using a process of prioritization following Saaty s AHP. There can be innerdependencies and feedback within criteria, sub factors and alternatives which may have potential effects on the results. To study the effects of innerdependencies among factors we have used ANP and compared the results obtained by the two methods. We have suggested the implementation of developed strategies simultaneously through different entities involved with the chain, as government agencies, academic and research institutes, industrial associations and entrepreneurs themselves.
Sustainability has become increasingly important. Existing project management methodologies are underdeveloped in sustainability. PM² is a methodology developed by the European Commission that aims to provide solutions and benefits to organizations. However, it doesn't include sustainability in its guide, because it aims to be generic. PRiSMTM aims to make the project management process more sustainable, it is based on the P5™ standard that aims to align portfolios, programmes and projects with sustainability. The major difference between the two methodologies is their main objectives. PRiSMTM has P5 Impact Analysis and Sustainability Management Plan as the main differentiating deliverable compared to other approaches, including PM². The most cited characteristic of PM² was to include best practices from other bodies of knowledge, and in PRiSMTM and P5™, it was to be an extension of the Triple Bottom Line, as it also includes product and process. The CEO of the PM² Alliance believes that PM² aims to be generic and usable for any project, so a focus on sustainability would remove the "elasticity" of the methodology. However, users wishing to use PM² and consider sustainability can include it in the additional objectives and use the P5 Impact Analysis and Sustainability Management Plan.
