“…Only six days prior to this, electronic chart systems (ECDIS, [9]) became compulsory worldwide. While the presence on the bridge of a blonde Moldavian woman inspired the media, nautical academics drew attention to the indiscernibility of obstacles within over-detailed screens as a risk factor for (deadly) disasters [10].…”

SummaryBackground: Planning and controlling surgical operations hugely impacts upon productivity, patient safety, and surgeons' careers. Established, specialized software for this task is being increasingly replaced by "Operating Room (OR)-modules" appended to enterprise-wide resource planning (ERP) systems. As a result, usability problems are re-emerging and require developers' attention. Objective: Systematic evaluation of the functionality and social repercussions of a global, marketleading IT business control system (SAP R3, Germany), adapted for real-time OR process steering. Methods: Field study involving document analyses, interviews, and a 73-item survey addressed to 77 qualified (> 1-year system experience) senior planning executives (end users; "planners") working in surgical departments of university hospitals. Results: Planners reported that 57% of electronic operation requests contained contradictory information. Key screens contained clinically irrelevant areas (36 +/-29%). Compared to the legacy system, users reported either no improvements or worse performance, in regard to co-ordination of OR stakeholders, intra-day program changes, and safety. Planners concluded that the ERP-planning module was "non-intuitive" (66%), increased planning work (56%, p=0.002), and did not impact upon either organizational mishap spectrum or frequency. Interviews evidenced intra-institutional power shifts due to increased system complexity. Planners resented e.g. a trend towards increased personal culpability for mishap. Conclusions: Highly complex enterprise system extensions may not be directly suited to specific process steering tasks in a high risk/low error-environment like the OR. In view of surgeons' high primary task load, the repeated call for simpler IT is an imperative for ERP extensions. System design should consider a) that current OR IT suffers from an input limitation regarding planning-relevant real-time data, and b) that there are social processes that strongly affect planning and particularly ERP use beyond algorithms. Real improvement of clinical IT tools requires their independent evaluation according to standards developed for pharmaceutical subjects.

Automation of processes in shipping has emphasized the importance of using modern technologies in the maritime industry. Modern technologies make it possible to automate various aspects of shipping, ranging from navigation and ship traffic control to power plant control and data processing. They help to increase the safety of maritime operations, reduce risks and improve the efficiency of vessels. This article describes the principles of navigation systems and their interconnection with other ship management and control systems. The advantages provided by navigation systems in the automation of ship navigation, including increased navigation accuracy, safety, route optimization and improved operational efficiency, are considered. It was determined that the use of navigation systems and their integration with other ship management and control systems as the basis of navigation safety, taking into account modern trends and development in the field of navigation of sea vessels, including the use of artificial intelligence and automatic control, characterizes the high urgency of the problem and the need for its solution. The article provides an overview of current trends and developments in the field of navigation systems, such as the introduction of remote monitoring and ship control systems, the use of artificial intelligence and automatic control. The article offers an analysis and understanding of the role of navigation systems in the automation of navigation, as well as information on the latest technological innovations in this area of the maritime industry.

“…In this case, the most important factor for effective decision-making by the navigator is completeness, quality and intensity of incoming navigation information from ECDIS systems and sensors. International maritime and information technology organizations, within their legislative powers, have determined the conditions and requirements for the operation of navigation information systems [4,5].…”

Taking into account current trends in the development of ergatic maritime transport systems, the factors of the navigator’s influence on vessel control processes were determined. Within the framework of the research hypothesis, to improve navigation safety, it is necessary to apply predictive data mining models and automated vessel control. The paper proposes a diagram of the ergatic vessel control system and a model for identifying the influence of the navigator “human factor” during navigation. Within the framework of the model based on the principles of navigator decision trees, prediction by data mining means is applied, taking into account the identifiers of the occurrence of a critical situation. Based on the prediction results, a method for optimal vessel control in critical situations was developed, which is triggered at the nodes of the navigator decision tree, which reduces the likelihood of a critical impact on vessel control. The proposed approaches were tested in the research laboratory “Development of decision support systems, ergatic and automated vessel control systems”. The use of the Navi Trainer 5,000 navigation simulator (Wärtsilä Corporation, Finland) and simulation of the navigation safety control system for critical situations have confirmed its effectiveness. As a result of testing, it was determined that the activation of the system allowed reducing the likelihood of critical situations by 18–54 %. In 11 % of cases, the system switched the vessel control processes to automatic mode and, as a result, reduced the risk of emergencies. The use of automated data mining tools made it possible to neutralize the negative influence of the “human factor” of the navigator and to reduce the average maneuvering time during vessel navigation to 23 %
