New steps towards dealing with the traditional common sense for managing or governing the seaport are required for assisting the new generation of managers and port authorities. Sematic intelligence answers dilemmas of complex realities and alignments of strategies such as which strategic position may have the seaport facing the growing number of international networks and international treaties. In Management and Computational Sciences, semantic intelligence has been discussed mostly from technological perspectives; however, a higher thinking intelligence for managing and govern the seaport surplus the classical intelligence approach found in literature.

Specifically, it refers to port informational integration in a context of sustainable factors, practices and functions of the port. It discusses the systemic perspective of port informational integration containing the boundaries of the complex system named Port Decision System Approach (PDSA) and presents the recognition of a decision-making situation as the step one in a methodology that offers a high-level support enhanced through the application of techniques from Computational Intelligence. The PDSA provides the necessary theoretical elements to recognise and deal with the inherent complexity of port informational integration that could be extended or modified as new knowledge emerges.

Management in supply chains has turned to a new paradigm to include sustainability so that organisations and business processes across and within them are now seeking for the achievement of social, environmental and economic objectives shared by organisation and the entire supply chain. In order to ensure that current logistics practices are sustainable in the long-term, the concept of reverse logistics becomes part of the supply chain management allowing the efficient and effective management of product recycling and reuse. This paper is a contribution on reverse logistics practices as it attempts to assess in what extend Colombian enterprises implement reverse logistics concepts. Conceptual models are presented in this paper as 'evidence for the field' and documented through a rigorous exploratory study. Results are discussed and suggestions to decrease a negative impact on the environment are presented.

As part of the supply chain management, this concept allows the efficient and effective management of product recycling once their life cycle is finished. Although the practice of RL is part of a sustainable strategy for the management of the supply chain, there is no much literature about its practice in Colombia. In this context, this paper is a first research approach of RL practices in Colombian enterprises, with a particular focus on the plastic sector. After a first analysis of the definitions of RL, some conceptual models are presented for the companies under study. This paper then analyses the results of an exploratory study of RL practices within the Colombian plastic sector. Results of this study are discussed and suggestions to decrease a negative impact on the environment are presented.

For decisions in domains that involve many different factors and concerns, such as seaport integration, data may exist across many repositories managed by different organizations with different goals and foci, not to mention different data structures, entities, labels, units of measurement, categories and time periods. To use this data for decision making, approaches to combine the data and handle missing values are two of the problems, among others, that need to be addressed. In this paper we discuss the need for managing micro and macro-level data and our approach to handle missing values.

Identification of this status can assist Port Authorities (PAs) in making decisions concerned ...

Service requests are also available at different times known at the initial time of route planning. This paper presents an approach based on the generation of service sequences (routes) using randomness. Both the single-vehicle and the multiple-vehicle cases are studied. Our approach is validated using random-generated data and compared against the optimal solution obtained by mathematical programming for small-sized instances, as well as against known lower bounds for medium to large-sized instances. Results show that our approach is competitive with reference to the value of the objective function, and requires less computational time in comparison with the exact resolution procedure.
