Nowadays, the denomination of “smart” is associated with several production and management devices and to logistics and distribution, too. Thus, this qualification is used in different application fields. All of them are different and diverse, but the most important common characteristics of these devices or Smart Systems are based on their novel and more efficient way of working. The smart trend is consolidated in the port environment, too. The ports’ need to become more intelligent is modifying their own operations. Therefore, this paper includes an analysis of Spanish Port System, in order to evaluate its ports, considering the new concept called “Smart Port”. Some indicators and measure variables are defined, to allow for quantifying technical items. These items—both quantitative and qualitative ones—which reflect, in the most objective and complete way possible, the adaptation and achievement of characteristics and objectives associated with the Smart Port concept in all ports were studied, in order to obtain an index of Smart Ports that allows us to calculate the ranking of the Spanish Smart Ports. Considering the analysis of the Smart Port concept and its current and future trends, it has been determined that the development of a port must be based on the digitalization, on use of ICT and on automation of port processes.

In the specific case of maritime transport, one of the most notable examples of digitalization is smart ports. Their positive impact on the supply chain is enabling processes to be optimized through smarter production. In the case of Spain, the Spanish public entity Puertos del Estado (Puertos del Estado is a public business entity dependent on the Spanish Ministry of Transport, Mobility and the Urban Agenda, with overall responsibility for the entire state-owned port system.) has launched Ports 4.0, the largest open innovation fund for the logistics-port ecosystem. It is therefore necessary to know the point of digitalization in which the Spanish ports are and the present scenario in which they develop their activity. For this purpose, a SWOT analysis (Strengths-Weaknesses-Opportunities-Threats analysis) is proposed, which is an ideal tool to make a reliable diagnosis of the port system in relation to a certain project before which we wish to make a strategic decision, in this case digitalization, in order to establish a concrete action plan in this regard. This should be the first step towards developing the Ports 4.0 project. The main conclusion of the analysis is that Spanish ports are currently at a medium high level of digitalization, and that they continue to update and innovate in order to be increasingly competitive in this market, despite the fact that there is still a long way to go in digitalization. The main challenge for Spanish ports is that technology alone is not useful enough to reach Ports 4.0 status; the technology also needs to be used in an integrated, open and joint way by all the agents of the port community, which is one of the main handicaps at present.

In the current economic, social and political environment, society demands a greater variety of outcomes from the public logistics sector, such as efficiency, efficiency of managed resources, greater transparency and business performance. All of them are an indispensable counterpart for its recognition and support. In case of port planning and management, many variables are included. Use of Bayesian Networks allows to classify, predict and diagnose these variables and even to estimate the subsequent probability of unknown variables, basing on the known ones. Research includes a data base with more than 40 variables, which have been classified as smart port studies in Spain. Then a network was generated using a non-cyclic conducted grafo, which shows port variable relationships. As conclusion, economic variables are cause of the rest of categories and they represent a parent role in the most of cases. Furthermore, if environmental variables are known, subsequent probability of social variables can be estimated.

Actualmente, nos encontramos inmersos en la cuarta revolución industrial o industria 4.0. Los puertos están viviendo un proceso de digitalización, similar al de otros sectores industriales y económicos. El objetivo es la automatización para hacer más eficiente y predictiva la cadena de suministro, persiguiendo también la intermodalidad y desarrollar una gestión más sostenible para reducir la contaminación y ganar flexibilidad y agilidad. Sin embargo, este proceso no está exento de complejidad y problemas que dificultan su implantación en el caso español. Es por ello que es papel de los expertos es realizar un análisis de la situación actual, reflexionando sobre las posibilidades y los riesgos que presenta en nuestro país la digitalización del sector portuario. Para llevar a cabo dicho análisis se recurrirá a un panel DELPHI cuyo resultado final será la realización de un matriz DAFO. En el artículo se recogen los resultados obtenidos tras el estudio realizado.

The sustainability of the planet is a burning issue that has affected all areas of life. The port sector is also affected by this increasing focus on protecting the environment and making efficient and intelligent use of the available resources. The search for sustainable policies in the Spanish port system is a priority. A detailed analysis of the sustainability of the Spanish port system is presented here, through use of a graphic tool that is a pioneer in the port field: the business observation tool (BOT). The aim of this research study was to identify the minimum elements to be considered when formulating the concept of sustainability linked to Spanish ports, allowing the reality of the conditions of the port environment to be known and establishing possible scenarios to evolve beyond the observed reality, towards harmonious and balanced growth by means of an observation model through the BOT. This pioneering and innovative project in the application of this strategy has required research considered as approximate through analysis of the current condition of the Spanish port system and the study of adjacent ports as examples. The paper concludes with the fundamental idea of the need to promote the implementation of increasing measures towards intelligent ports.

The fourth industrial revolution is characterized by a high level of digitalization of systems and processes. This revolution has reached the Spanish ports. They have been investing for years in the implementation of new technologies, aimed at promoting sustainability and environmental quality, as well as seeking a more efficient and orderly logistics. Ports are moving towards their digital transformation, which is materialized in the well-known Ports 4.0. These intelligent ports, or Smart Ports, cover a multitude of aspects and variables. Automation, digitalization, technologies that allow interoperability, transparency, decentralization, and customer experience define the context of the application of the concept 'Ports 4.0' to the Spanish logistics-port sector. How to achieve a satisfactory digitization process that allows progress towards Port 4.0 in the Spanish port system is one of the questions being raised recently. The Spanish port world could be represented by a red ocean, since in a very generalist way it can be said that it is a marked described by a fierce competition lacking in differentiation. Therefore, with this proposal, the aim is to take the Spanish port system to a blue ocean, where a suitable strategy and innovation generate leaps in value that make competitors irrelevant because customers compare different products and services. To be able to respond to this, the Blue Ocean Strategy is planted, leaving aside the competition between ports and generating new demand. From the study carried out, it is concluded that Spanish ports still have a long way to go in terms of sustainability. It also concludes that a new management model would mean the innovation in value that is necessary for the process towards ports 4.0.
