We are currently organizing a Special Issue entitled 'The Complexity of Sustainable Project Management'.
This Special Issue seeks to publish papers featuring novel research on this topic. Modern projects cannot ignore this critical issue and, therefore, project management is faced with unique and new challenges; not only do they need to be fiscally sound, but they also need to be socially and environmentally sustainable. This can be achieved by the adequate management of resources.
Obviously, this is only a partial description of the complexity of sustainable project management, as the concept of sustainability today also includes labor practices, human rights, fair business dealings, social responsibility and consumer issues.
The aim of this Special Issue is to cover the broad range of topics involved in sustainable project management. In the environment sphere, we welcome contributions on sustainable resource use, pollution prevention, and climate change mitigation. Community involvement and engagement is another major factor in sustainable project management, including employee training and skills development, wealth and income creation, and stakeholder management. Important issues in human resource management are work conditions, health and safety.
This Special Issue will focus both on projects that deliver sustainable goods or services and on projects delivered following sustainable processes. Original research articles and reviews are welcome. Research areas may include but are not limited to the following:
Sustainable project management and the business case for sustainability;
Evaluating the impact and integration of sustainability in project management tools and techniques;
Critical factors, best practices and determinants for effective sustainable project management implementation;
Project managers and the tradeoffs between sustainability-related objectives in decision making;
Innovative sustainable project practices and applications.
We look forward to receiving your contributions.

This paper outlines a new approach to project scheduling in an LPM framework. We develop and solve a math program for balancing project time, cost, value, and risk, seeking to maximize the project value subject to schedule and budget constraints in multimode stochastic projects. Each activity mode contains fixed and resource cost information and duration data, and may be associated with one or more value attributes, thereby integrating project and product scope. By selecting a mode for each activity, the value of the project is determined, and stability is achieved by complying with on-schedule and on-budget probability thresholds. We solve the problem by applying a reinforcement learning-based heuristic, a tool known for obtaining fast solutions in a variety of applications in uncertain environments. We validate the method by comparing the results to two benchmarks—those obtained by solving a mixed-integer program, and the values obtained by adapting a recently published genetic algorithm. Our method generates competitive values faster than the benchmarks, making this approach interesting for the planning stage of a project, when multiple project tradespace alternatives are explored and solved, and runtime is limited. Our approach can be applied by decision-makers to calculate an efficient frontier with the best project plans for given on-schedule and on-budget probabilities.

O resultado consiste na crescente dificuldade para a exploração das economias de escala 'tradicionais' por meio de equipamento altamente especializado e a produção de bens padronizados. Daí a recente ênfase no conceito de economias de escopo. Entretanto, várias conclusões imprecisas são encontradas na literatura referentes à transição de economias de escala para economias de escopo. O propósito deste artigo é identificar algumas dessas conclusões e introduzir argumentos no sentido e organizar a discussão sobre o assunto.
