Dissertação para obtenção do Grau de Mestre em
Engenharia Electrotécnica e de ComputadoresService-oriented Architecture (SOA) paradigm is becoming a broadly deployed standard for business and enterprise integration. It continuously spreads across the distinct layers of the enterprise organization and disparate domains of application, envisioning a unified communication solution. Service-oriented approaches are also entering the industrial automation domain in a top-down way. The recent application at device level has a direct impact on how industrial automation deployments will evolve. Similarly to other domains, the crescent ubiquity of smart devices is raising important lifecycle concerns related to device control, monitoring and management. From initial setup and deployment to system lifecycle monitoring and evolution, each device needs to be taken into account and to be easily reachable. The current work includes the specification and development of a modular, adaptive and open infrastructure to support the control, monitoring and management of devices and services in an industrial automation environment, such as a shop floor system. A collection of tools and services to be comprised in this same infrastructure will also be researched and implemented. Moreover, the main implementation focuses on a SOA-based infrastructure comprising SemanticWeb concepts to enhance the process of exchanging a device in an industrial automation environment. This is done by assisting (and even automate)this task supported by service and device semantic matching whenever a device has a problem. The infrastructure was implemented and tested in an educational shop floor setup composed by a set of distributed entities each one controlled by its own SOAready PLC. The performed tests revealed that the tasks of discovering and identifying new devices, as well as providing assistance when a device is down offered a valuable contribution and can increase the agility of the overall system when dealing with operation disruptions or modifications at device level.

The paper details the usage of mmWave radars to track people and monitor their movement through predefined zones of interest. The theoretical part describes the physical nature of the technology and then describes algorithms which can be used to monitor using it to monitor the movement of people. In the practical part, I have developed a concrete algorithm which can be used to monitor customer queues and cash registers in shops and inform the cashiers when their presence is needed, as well as gather impersonal GDPR-compliant data about the customer's habits. Afterwards, I have developed a visualization for the Windows platform, which can be used to communicate with the radar, manage its configuration, visualize the events in real time and perform further analysis of the measured data.

Full textAbstract:
Ce travail de recherche met en avant l'intérêt qu'offre la simulation en ligne comme outil d'aide à la décision, outil centré sur le pilotage d'atelier vis-à-vis d'événements se produisant en temps réel et pour un horizon à très court terme. Après avoir présenté le contexte général du pilotage des systèmes de production, nous avons étudié les outils existants et utilisés industriellement pour l'exploitation de la production, de même que les outils d'aide au pilotage permettant d'assurer le respect optimal des objectifs fixés. Après un travail préalable sur la simulation hors ligne, nous proposons de coupler un outil de simulation en ligne à un outil d'exécution d'atelier de type MES afin de piloter en temps réel le processus de production. Une démarche de modélisation faisant appel de façon complémentaire à deux approches, analytique et simulatoire, est finalement mise en place. Nous mettons en exergue l'utilisation de la simulation de flux en ligne pour aider au pilotage d'un processus opérationnel. Ainsi nous modélisons le processus de pilotage en temps réel afin de décrire les fonctions requises. Pour cela, nous utilisons différentes stratégies d'utilisation des simulateurs en ligne pour le pilotage, avec un ou deux modèles et avec plusieurs méthodes d'utilisation de ces modèles. La simulation en ligne apporte alors des informations objectives sur les conséquences à court terme d'un événement, ainsi que sur les divers scenarii de correction envisagés. Pour mieux convaincre les industriels de l'intérêt de la simulation en ligne, nous présentons des solutions pratiques aux spécifications et besoins énoncés précédemment en nous appuyant sur une plate-forme expérimentaleThis research work highlights the interest of online simulation as a decision support tool. This tool is focused on workshop control in relation with real time and short-term events. Online simulation enables to analyze and compare scenarios affecting the production, such as failures or unexpected orders. Moreover online simulation allows a very short term projection in the future in order to quantify the consequences of some unexpected event: we call it projection simulation. Finally, online simulation is helpful to choose the solution that will reduce the impact of a critical event, through the simulation of several scenarios. To conclude, online simulation is one the most interesting decision support tool in workshop piloting. However, there are few industrial applications in manufacturing systems. The first part of this research work introduces the overall context of production system management. The different generic functions of controlling the production, the modes of piloting and the evolutions of workshop are detailed. We also explain piloting typologies according to their reactivity. In the second part, we study the existing software tools used in industry for the operation of production, and support tools that ensure optimal compliance in regard to the objectives. After a preliminary work on the offline simulation, we propose to couple an online simulation tool with a type MES delivery tool in order to control the production process in real time. A modeling approach using two complementary approaches, an analytical one and simulation, is then introduced. The objective of the third part is to emphasize the use of online flow simulation to assist in operating a production process. Thus we model the process in real time to describe the required functions. Therefore we try out different strategies of use of online simulators, through one or two models and several methods of using these models. Online simulation then provides realistic information on the short-term consequences of an event, as well as on the different ways of correcting the scenarios. To convince industry of the relevance of online simulation, the fourth part presents practical solutions to the specifications and requirements previously stated. An experimental platform helped us validate the concept of online simulation as piloting support tool, but also underline the difficulties of development

"A service orientated architecture and wireless sensor network approach applied to the measurement and visualisation of a micro injection moulding process : design, development and testing of an ESB based micro injection moulding platform using Google Gadgets and business processes for the integration of disparate hardware systems on the factory shop floor." Thesis, University of Bradford, 2014. http://hdl.handle.net/10454/13362.
Full textAbstract:
Factory shop floors of the future will see a significant increase in interconnected devices for monitoring and control. However, if a Service Orientated Architecture (SOA) is implemented on all such devices then this will result in a large number of permutations of services and composite services. These services combined with other business level components can pose a huge challenge to manage as it is often difficult to keep an overview of all the devices, equipment and services. This thesis proposes an SOA based novel assimilation architecture for integrating disparate industrial hardware based processes and business processes of an enterprise in particular the plastics machinery environment. The key benefits of the proposed architecture are the reduction of complexity when integrating disparate hardware platforms; managing the associated services as well as allowing the Micro Injection Moulding (µIM) process to be monitored on the web through service and data integration. An Enterprise Service Bus (ESB) based middleware layer integrates the Wireless Sensor Network (WSN) based environmental and simulated machine process systems with frontend Google Gadgets (GGs) based web visualisation applications. A business process framework is proposed to manage and orchestrate the resulting services from the architecture. Results from the analysis of the WSN kits in terms of their usability and reliability showed that the Jennic WSN was easy to setup and had a reliable communication link in the polymer industrial environment with the PER being below 0.5%. The prototype Jennic WSN based µIM process monitoring system had limitations when monitoring high-resolution machine data, therefore a novel hybrid integration architecture was proposed. The assimilation architecture was implemented on a distributed server based test bed. Results from test scenarios showed that the architecture was highly scalable and could potentially allow a large number of disparate sensor based hardware systems and services to be hosted, managed, visualised and linked to form a cohesive business process.

Full textAbstract:
The shipping industry is becoming increasingly visible on the global environmental agenda as air emissions from vessels make an increasingly conspicuous contribution to air quality. With the forecast expansion of world trade; scientists are estimating global emissions to increase by 30% to 1.45 billion tonnes in the next decade. This would make shipping responsible for 6% of global emissions by 2020. The International Marine Organisation (IMO) Annex VI entered into force in 2005 and is currently the most important international treaty governing emissions to air from ocean going vessels. It has set strict limits on sulphur dioxide (SO2) and nitrogen oxide (NOx) emissions from ship exhausts, prohibits the deliberate emissions of ozone depleting substances, and places a global cap on the sulphur content of marine fiiel. As an alternative to using low sulphur fliel oils, ships have the option to fit an exhaust gas cleaning system such as a seawater scrubber (SWS) or to use any other feasible technology to limit SO2 emissions. SWS transfers SOx (ca. 95%) and partly NOx (ca. 20%) into aqueous solution, producing acidic solutions which are then buffered with seawater and finally discharged into the sea.

The US Navy implements structural preventative maintenance procedures onboard its vessels using ship's personnel inspection. These procedures have been largely successful in identifying major problem areas before any interference with mission execution has occurred. However, changes in the Navy's manning philosophy to minimal manning and new ship designs focused on automation encourage a re-evaluation of these structural preventative maintenance procedures. Automation of structural inspection and damage detection would reduce associated manpower costs as well as inform better preventative maintenance schedules for US Navy vessels. This study outlines a modeling tool for structural health monitoring using nonlinear Kalman Filter methodologies such as the Extended Kalman Filter and the Ensemble Kalman Filter to identify damage within a structural model. Through the observation of structural responses and the formulation of a Kalman Filter, it is possible to produce estimates of structural parameters related to damage, specifically changes to elastic modulus and changes in material density. The results of this modeling tool were evaluated to quantify the time and length scales required for damage detection and were validated against a structural model generated in the MAESTRO Global Structural Analysis software suite.

Full textAbstract:
The complete ban on TBT in marine antifouling coatings in 2008, rocketing fuel prices over the past six years, environmental concern and upcoming energy efficiency indices for ships have resulted in a strong interest of the shipping industry to monitor, evaluate and optimise ship performance. Furthermore, the complete ban on TBT in anti-fouling coatings resulted in new types of foul-release hull-coatings, based con silicon, whose effectiveness and performance still needs to be evaluated. Because of the difficulty of measuring coating roughness in service and the large effect of marine bio-fouling on ship performance, a research project was setup at Newcastle University in collaboration with a major paint company to investigate the ways to evaluate hull coating through ship performance monitoring. This thesis describes the details of this project which aimed to investigate the feasibility of a real-time ship performance monitoring and analysis (PM&A) system by implementation and evaluation onboard a 16m research vessel and 300.000dwt VLCC. The thesis starts with a review of the state of art of PM&A systems. The main weaknesses of existing PM&A systems is that often abstract logbook data is used as input and that too little attention is paid to data quality. Furthermore, the systems often act as a black box, showing little insight in data analysis, harming the reliability and trustworthiness of output indicators. Additionally, there are large differences in the way that performance data is corrected to standard conditions, resulting in contradicting and unreliable performance indicators. The thesis focuses therefore on theoretically sound, transparent data analysis and improved data collection. In the thesis, all performance affecting environmental and operational conditions have been reviewed including sensor characteristics and data acquisition aspects. Based on the experience from the analysis of the data collected from both vessels, it reveals that automatic, real-time data collection and rational filtering for periods of acceleration, deceleration, course deviation, drift, shallow water and ship motion is the way forward for accurate performance monitoring. Performance analysis is highly sensitive to errors in shaft torque and ship speed through water. A frequently calibrated/validated shaft torque & RPM sensor and Doppler speed log are therefore the most important sensors for performance monitoring. Speed logs are T.W.F. Hasselaar PhD thesis, 2010 ii affected by many environmental conditions and cannot be used directly for performance monitoring. Other ways to determine ship speed through water, e.g. using the propeller inflow speed, are however affected by hull fouling and loading deviations unless corrected for accordingly. Corrections using full scale trials are then necessary to avoid overestimation of the effects of hull fouling on ship performance. To avoid these errors, a method is described to use the speed log by evaluating its reliability and utilise its reading for performance analysis only in periods where it can be considered reliable. A new transparent analysis method is described to analyse ship performance based on conversion of torque and rpm at constant ship speed. The method differentiates between the hull and propeller performance by empirically correcting the propeller open water diagram for roughness (periodically measured by divers). Evaluation of the proposed PM&A system on both vessels indicates that reliable performance indicatgors can be calculated but that fluctuations in performance indicators of ±12% remain unavoidable due to inaccurate wave observations and errors from the speed log. Trials on the research vessel furthermore show that the system is able to identify fouling, but sensor accuracy requires further research so that fouling can be defined with less performance data and higher reliability. This thesis demonstrates for the first time in open literature that the design and implementation of a transparent and fully automatic, real-time, shipboard PM&A system is perfectly viable and can be installed on any ship with the use of reliable sensors.

Full textAbstract:
Shot peening is a cold-working process by which residual compressive stresses are being induced in the surface region to increase the fatigue strength and the resistance to stress-corrosion cracking. This study covers non-destructive measurement of surface residual stresses in the shot-peened steel components by a micro-magnetic technique, named as Magnetic Barkhausen Noise (MBN) method. For this purpose, various low alloy steel specimens were prepared by a controlled shot peening process with different intensity, impact angle and coverage values. The measurements showed that a clear relationship exists between residual stresses and the MBN signals. Residual stress values determined by MBN technique were also verified by X-ray diffraction measurements.

Full textAbstract:
Traditional naval vessels with steel structures have the benefit of large safety factors and
a distinct material endurance limit. However, as performance requirements and budget
constraints rise, the demand for lighter weight vessels increases. Reducing the mass of
vessels is commonly achieved by the use of aluminum or composite structures, which
requires closer attention to be paid to crack initiation and propagation. It is rarely
feasible to require a lengthy inspection process that removes the vessel from service for
an extended amount of time. Structural health monitoring (SHM), involving continuous
measurement of the structural response to an energy source, has been proposed as a step
towards condition-based maintenance. Furthermore, using a passive monitoring system
with an array of sensors has several advantages: monitoring can take place in real-time
using only ambient noise vibrations and neither deployment of an active source nor visual
access to the inspected areas are required.
Passive SHM on a naval vessel is not without challenge. The structures of ships are
typically geometrically complex, causing scattering, multiple reflections, and mode
conversion of the propagating waves in the vessel. And rather than a distinct and
predictable input produced by controlled active sources, the vibration sources are hull
impacts, smaller waves, and even onboard machinery and activity. This research
summarizes findings from data collected onboard a Navy vessel and presents
recommendations data processing techniques. The intent is to present a robust method of
passive structural health monitoring for such a vessel using only ambient vibrations
recordings.

Full textAbstract:
Vid nybyggnation eller modernisering av fartyg installeras ofta avancerade integrerade övervakningssystem i maskinkontrollrum. Det är därför viktigt att de maskinbefäl som ansvarar för driften av fartyget innehar en utbildning och kunskap om hantering och felsökning av övervakningssystemen. Syftet med studien är att undersöka om maskinbefäl får tillräckligt med utbildning på nya integrerade övervakningssystemen för att utföra sina arbetsuppgifter på ett säkert och tryggt sätt. I den här studien har en enkät skickats ut till maskinbefäl ombord nybyggda fartyg där individerna får möjlighet att svara på hur de upplever möjlighet att genomgå utbildning och få kunskap över hur systemen fungerar. Studien visar att majoriteten av de tillfrågade befälen upplever att de innehar tillräcklig kunskap om övervakningssystemen för att kunna utföra sina arbetsuppgifter på ett säkert och tryggt sätt. Studien visar att majoriteten av befälen inte har blivit erbjudna en utbildning på systemen och att de som inte blivit erbjudna hade önskat få en utbildning. Studien visade att utbildningarna som erbjudits ofta är produktspecifika och inte installationsspecifika vilket gör att de inte upplevs som optimala då konstruktion och lösningar ofta avviker emellan installationer med samma produkter. Utbildning erbjuds av tillverkaren men ofta är det bara en liten del av maskinbefälen som erbjuds en plats. Studien visade också att de befäl som inte fick utbildning behövde tillskansa kunskaperna genom att själv utbilda sig ombord antingen i samband med avlämning eller under ordinarie drift. Slutsatsen är att maskinbefälen bör genomgå en utbildning innan de mönstrar på första gången och att det bör ges möjlighet till en uppföljande utbildning efter att besättningen arbetat med systemen en tid. För att avlösande besättningar ska kunna få möjlighet att sätta sig in och tillgodogöra sig kunskap om systemen bör mer tid ges vid avlösning.During construction of new ships or modernization of ships, integrated automation systems is often installed in the engine control room. It is of importance that the responsible engine officers are familiar with how the system works and that they can perform troubleshooting if eventual faults occur. The aim of the present study is to investigate whether the engineer officer get enough training on new integrated surveillance systems to perform their duties in a safe and secure manner. In this study a questionnaire was sent to engine officers signed on new ships where they got the opportunity to give their answer how they experience the possibility to be trained and acquire knowledge how the systems work. The majority of the engine officers who answered the questionnaires felt comfortable to operate the ship safely. The study showed that the training courses offered often were product specific instead of installation specific, which was not optimal because there can be differences between construction and handling after installations of the same products. The survey showed that a majority of the officers had not been offered training on the monitoring system. The officers who were not offered training expressed a wish to be able to participate in training. Training on the system is offered by the manufacturer but often only a few of the engine officers is offered training by the shipping company. Earlier studies show that crews that participates in the building and delivery process on the shipyard or during installation of a new system receives training on site, the officers that come onboard as reliever after trial run, maiden voyage or during normal operation often have to learn by doing. The conclusion is that the officers should be given the opportunity to participate in training before signing on and also a follow up training course after working with the system for a while. To give the relieving officers a chance to familiarize themselves and assimilate knowledge of the system, there have to be more time available in conjunction with leave.

The growth of global atmospheric emissions from ships forced IMO and the EU to issue restrictive maritime laws to regulate ship emissions. The earlier MARPOL convention is designed to limit mainly, the SO_X and NO_X pollutant emissions of ships without clear regulation on the method and procedure for emission monitoring. In 2013, the EU proposed the MRV regulations for shipping GHGs. Merchant ships navigating to EU port merchants must self-monitor CO_2 emissions, calculate fuel consumption and emission during operation, in order to effectively manage GHGs emissions from ships and therefore meet regional carbon reduction targets. In the face of international regulations, ships in the future must choose method for exhaust monitoring. Four monitoring methods are provided in the monitoring section of the MRV regulations, but many ship owners are burdened by factors such as cost of expensive equipment and ease of operation. This study explored the possibility of using existing technology to incorporate a highly maneuverable drone with gas analyzers. It is flied to ship's exhaust plume for actual exhaust gas monitoring. The test data are compared with estimate data obtained from calculations and literature to verify the reliability. The results obtained in this experiment show that there is potential of applying a drone for monitoring emission from ships. Many technical problems need to be overcome. For example, the effect of air stream generated by the drone rotor can disperse the surrounding gas substances, causing errors in measurement. In addition, the micro-environment can also influence the measurements. Solving these problems through further study will be the key to the application of drone on ship emission monitoring in the near future.

ABSTRACT Due to ever advancing information technology, there is a tendency for ships to up-grade its communication facilities to have on-line satellite communication. With such technology, not only the head offices of Owners or Operators are able to distribute vital information to their ships sailing on different waters of the world, but also crew members on board can as well get instant instructions on shore through their IP-based facilities. In such manner, information concerning health condition of the power system on ship can also access on shore through a remote monitoring and diagnostic system, which has been more commonly used on shore, so that maintenance and repair of a ship can also be supported by shore’s manpower. This research has integrated different technologies such as satellite communication, ship’s propulsion system, on-shore maintenance technical know-how, etc. An efficient prototype system is designed which serves pre-warning, diagnostic, and management purposes for ships. A remote monitoring system is designed for a studied ship which is equipped with the watch–free monitoring system in the engine room, information concerning the operating conditions for propulsion system of the ship is connected to the display graphs of the computer both on ship and on shore, so that discussions can be made with each other for possible policies to resolve the problems met on ship. Results show that the designed remote monitoring system is function well, all the important information on ship can as well displayed on shore’s computer, so that possible backup can be obtained from shore for helping engineers on ship to solve their problems. For the ship that is not equipped with a proper monitoring system that is compatible with the proposed design, a generalized remote monitoring system is proposed such that new installed sensors are connected to a PLC and is linked with the INMARSAT on ship to transfer the monitoring data to the management computer on shore office, again the graphical display of the original design in this thesis can also employed to explore information containing in the transferred data, so that it can be helpful to improve the maintainability of the propulsion system on ships.

Abstract In the past, the shoe manufacturing industry had been created lots of benefits and opportunities in Taiwan’s economy; however, since it is a labor-intensive industry, a lot of shoe companies were forced to move to China and Southeast Asia where labor fees are cheaper. In the same time, those shoe companies have been keeping on increasing oversea investments and became global organization to compete with other international companies in the world. Since the company is getting extended, how to manage a lager organization becomes the prime challenge for shoe manufacturer. Since the barcode system has been implementing in assembly manufacturing industry for years, it is already a mature technical; however, for shoe manufacturing industry, it is still in experiment stage. In this research, I will establish a barcode monitor system on a sport shoe production line. This system will collect and analyze the data of instant yield, and create a warning signal for unusual information found as well. This system is trying to help the manager in production line to acquire the real time situation and handle those unusual problems during production process. By comparing the data of material loss and rework information with before, the manager will be able to find solutions to decrease the cost of material loss and improve the situation of rework and further enhance the productivity.

Pue to the rapid development of technology, automation products are becoming more popular. As a result, traditional manpower operations are gradually replaced. Particularly, traditional water quality testing methods require operator to go to multiple locations to sample water and analyze the quality. Apparently, traditional water quality testing methods being time consuming, hence we are motivated to develop automatic water quality testing methods. In this thesis, we used an unmanned marine vehicle (UMV) and combined it with the remote water quality detection to implement a surveillance ship. In detail, the Arduino Uno is the control core to deal with the ship’s moving and obstacle avoidance; The Raspberry Pi core is used for GPS navigation and water quality detection. In addition, the operator sets the destination via a phone APP, and then Raspberry Pi will determine the current distance and the angle deviation between the surveillance ship and the destination; The surveillance ship automatically advances to the destination for water quality detection; Moreover, during the ship voyage, the operator can immediately cheak the view in front of the ship and the ship’s location by using the phone APP we designed. Finally, the detection data of water quality will be furth transmitted to the cloud database via WIFI, and the operator can grasp the water quality detection status through the phone APP.

In the recent decades, the average global temperature has been observed to rise gradually. The impact of global warming on the Earth intensifies increasingly. Maritime transportation is a major transportation mode of global logistics. Ports play a key role in maritime transportation. A large number of ship activities occurs inside ports, such as container loading, unloading, handling etc. Inevitably, these ship activities produce a large of quantity of pollution in ports. Many countries gradually pay attention to ship emissions monitoring, control and assessment. This research combines Geographic Information System (GIS), Automatic Identification System (AIS), and Fuzzy Theory with port air pollutant emissions inventory to construct two effective monitoring and assessment tools. First, an environmental impact indicator is developed by applying Fuzzy Theoryto monitor the real-time influence of the ship emissions on the environment in a port. Second, a ship emissions estimation model is used to analyze ship emissions in various scenarios for carbon reduction plans. The scenario simulation provides useful information for port managers’ decision making.

The ship weight is a very important indicator during the process of ship construction. Monitoring the ship weight in situ real time is very helps improve the quality control and reduce the cost of the ship. In this study, the main purpose is to establish a ship weight monitoring system based on the wireless sensor network technology. The tasks to complete the system include selecting the load bearing unit, the design of strain gauge back-end circuits, and the development of wireless sensor network and database of the host-function. Every information or changes of the ship weight under ship construction will be sent from shipyards to the engineers not in situ by this monitoring system. A set of the wireless sensor nodes which composed by the load bearing units was distributed under the boat cradle. Each node of the wireless sensor nodes network was capable to measure the weight and transmit the data to the host computer. The data can be saved to the database and transferred into the total weight and the center of gravity of the ship. Hence, the real time and daily information of the ship construction can be recorded in the computer and the database of information center of the machinery and shipbuilding Company. In this study, the proper strain gauge was decided and adhered to the load bearing unit designed by Ship and Ocean Industries R&;D Center. The load –strain curve of each load bearing unit has been completed through the experiment by the 100 tons universal testing machine. The wireless sensing network device adopting, the industrial PC setup, the wireless network topology, the database system, and the reading program for the end device and the industrial PC will be realized. Furthermore, the prototype system has been tested in the small shipyards building custom-made yacht. Although the result of the tests can be improved, the system showed its ability to measuring the ship weight in situ. In the future, the strain gauge adhesive technique needs to be modified to increase the stability and sensitivity of the load bearing unit. Hence, the wireless ship weight real time monitoring system can be utilized in the shipyards. It can continuously collect critical data of the ship and the work loading of the people in situ can be lowered. This can further enhance the manufacturing information control and the yacht quality in the construction process.

This study presents the hub of an AI-based (artificial intelligence) ship security monitoring system designed to supervise three different maritime monitoring tasks, including propeller-shaft fault detection and diagnosis, human medical diagnosis, and smoke- and temperature-based fire alarm. Particular software for the three tasks is developed using a combination of symbiotic evolution, fuzzy clustering, adaptive fuzzy classification, back-propagation neural networking, and grey theory. Essentially, a modularizing scheme for categorizing various monitored/controlled objectives appearing in the ship system is used in this study. Accordingly, two general-purpose software models, the diagnostic software model and the predictive software model, are proposed. These models implementing monitoring tasks properly are established consistent with the behavior characteristics of the monitored objectives. The diagnostic model is a symbiotic evolution-based fuzzy-neural diagnosis model applicable to the interpretation of complex current data. The predictive model is a grey-fuzzy prediction model, which is available to the crucial situation of early-prediction such as fire alarm for small differences in alarm time. When working together, these models can supervise a wide variety of modern maritime data, including electronic compass, hull motion sensors, engine shaft RPM and vibration sensors, GPS, temperature sensors, engine oil condition, and so on. The AI system has self-designing functions that can easily monitor new objects to be input, upon which the system will automatically develop specified monitoring, diagnosis, and response patterns for the new data. In essence, this methodology simplifies the tasks of system design and management, and increases system flexibility. Compared with several traditional methods by applying the same database, the proposed symbiotic evolution-based fuzzy-neural diagnosis model exhibits higher diagnostic rate and lower model construction time. The grey-fuzzy prediction model tested under the circumstances of open-flame and smoldering fires is compared with the commercial detector operating with the same condition. The experimental results reveal that the proposed model gives superior performance. The presented design is useful as a core model for developing more advanced AIs-based monitoring systems. As applied to the monitor maritime, the proposed system provides a good basis for the intelligently remote network-based integration of monitoring system, monitored objects and data. Consequently, the intelligent ship security monitoring system will be essential for optimizing the levels of safety, economy, convenience, and comfort.

Dissertação de mestrado integrado em Engenharia e Gestão IndustrialEsta dissertação foi desenvolvida no âmbito do projeto de final de curso de Mestrado Integrado em Engenharia e Gestão Industrial (MIEGI), da Universidade do Minho. O projeto foi efetuado em ambiente industrial, na empresa Bosch Car Multimedia Portugal S.A., no departamento de logística. O seu principal objetivo foi o de analisar o processo de abastecimento dos componentes que abastecem a área produtiva de inserção automática com vista a eliminar movimentações desnecessárias destes materiais e a diminuir custos de inventário e de armazenamento, e a validação, revisão e implementação de um sistema de monitorização de desempenho em tempo real para as atividades da logística interna. Relativamente ao processo de abastecimento dos componentes que abastecem a área produtiva de inserção automática, foi feita uma revisão da metodologia Ship to Line (STL), em que o principal desafio centrou-se na aplicação do STL à totalidade desses componentes, metodologia que, até à data, apenas estava implementada nos componentes “tipo A” (referências de maior consumo e/ou valor). Como principal resultado do trabalho efetuado, foi possível alcançar uma redução muito significativa do número de movimentos internos dos componentes em questão, o que proporcionou uma diminuição da carga de trabalho associada a estas atividades e ainda a libertação de posições de armazenagem no armazém principal. Em relação à validação de um sistema de monitorização de desempenho em tempo real, foram realizados diversos casos de teste, nos quais foram reportados e corrigidos os erros detetados, foram identificadas oportunidades de melhoria e, posteriormente, sugeridas e implementadas propostas para os pontos detetados. Foi planeada e monitorizada a fase de implementação e posterior estabilização da ferramenta. Após algum tempo de utilização da ferramenta no dia-a-dia operacional, não foi detetado nenhum erro com prioridade alta, daí poder-se concluir que a validação da ferramenta foi efetuada conforme o esperado. Foi ainda possível verificar a facilidade que a ferramenta proporciona na deteção de desvios ao normal funcionamento das atividades logísticas e apontado um exemplo concreto de uma melhoria de objetivo de produtividade suportada pelos outputs da ferramenta.
This dissertation was developed upon the final project for Mestrado Integrado em Engenharia e Gestão Industrial (MIEGI) of Universidade do Minho. It was conducted in an industrial environment on the logistics department of Bosch Car Multimedia Portugal S.A. Its main goal was the analysis of the components supply process for the automatic insertion productive area in order to eliminate components’ unnecessary movements and decrease inventory and storage costs, and validate a live performance monitoring system for internal logistic activities. Regarding the component supply process for the automatic insertion productive area, a revision over the Ship to Line (STL) methodology was performed. The challenge laid into applying STL to all components, methodology that to the date was only implemented to “Class A” components (higher consumption and/or value references). As main result for its appliance, it was possible to achieve a highly significant reduction on the number of internal movements for the concerned components. This yield a reduction on the workload related to these activities and also freed storage space on the main warehouse. As for the validation of a live performing monitoring system, many test cases were performed in which detected errors were reported and corrected, improvement opportunities identified and, later, proposals for detected points suggested and implemented. Implementation phase and later tool stabilization was planned and monitored. After some day-to-day usage time for this tool no error with high priority was detected, being the validation of this tool concluded as expected. It was also possible to verify the easiness this tool provides detecting deviations of normal logistics’ activities functioning and naming one example of productivity improvement supported by the tool’s outputs.
