Production Control System for CIM for Shipbuilding

Abstract: The Ship and Ocean Foundation has been conducting the feasibility study on CIM for shipbuilding and establishing a conceptual framework for the CIM for shipbuilding. Now the committee has finihshed the conceptual design of the pilot model of CIM for shipbuilding and has been prototyping it.The pilot model has the function of designing and production management, and the latter is realized by the following systems process planning, scheduling, and production control.The function of the production control system is to dispatch operations to workers and facilities for daily schedules, to monitor the status of operations in progress, and to troubleshoot in case of any troubles.In this paper dispatching and troubleshooting of the production control system and how the system should co-operate with the scheduling system are mainly discussed, and the concept of operation lot and production resources, which is found necessary on process of constructing the information model, and the method of dispatching which meets the functional requirement of the production control are proposed.

Towards a concept of operation using BIM technologies to improve productivity in construction projects

Abstract: The main objective of this paper is to evaluate the potential role of approaches that integrates the BIM and productivity measurement tools to increase the productivity in construction. A concept of operation will be proposed in the context of a pilot project that is designed to be used in future projects that use a new constructive system which is developed by industrial partners; this system offers a controlled and protected building environment. The research methodology is structured into four steps. 1) Benchmarking the firm's current situation through direct observations, surveys and interviews to identify issues and challenges related to the use of technologies, the current process, and the organizational structure of the project. 2) Defining the desired situation based on the project's stakeholders' expectations. 3) Using Focus Groups to determine and sort the requirements for an instrumentation of the new Construction Process. 4) Determining the instrumentation to be installed to support the new operation modes that are to be used by industrial partners. This instrumentation is supported by BIM, Productivity and ICT tools, and will be validated through site tests and interviews with project's stakeholders. Preliminary results showed a problem of coordination and communication in the project, and identified resistance factors to technology adoption, specifically BIM implementation. The paper also highlights several wastes that have been found during pilot project analysis, and that have been correlated to the wastes found from literature.

DeSIRE 2: Satcom Modeling and Simulation a Powerful Tool to Enable Cost Effective and Safe Approach to RPAS Operational Deployment

Abstract: Drones are a breakthrough systemic solution for a number of applications, from institutional and governmental purposes to a wide range of possible commercial applications. Autonomous and remotely controlled machines, fully integrated with many devices all connected wherever they are, are going to be a major part of the Internet of Things IoT, where satellite communication plays a pivotal role. Modelling and Simulation M&S are very helpful tools in the design and risk reduction of sustainable integration of Autonomous Systems into cost effective operational activities. As matter of fact, the M&S approach is extensively used in the DeSIRE 2 Demonstration of the use of Satellites complementing Remotely Piloted Aircraft Systems integrated in non-segregated airspace 2nd Element. The ongoing Project, recently launched by the European Space Agency and the European Defence Agency, aims to demonstrate a service based on a Remotely Piloted Aircraft RPA flying in Beyond Radio Line of Sight BRLOS using space assets SatCom, SatNav. The project has been kicked off in April 2015, after a selective process among important European consortia, and is leaded by Telespazio. Through Model and Simulation, within DeSIRE 2 it will be possible to:Decrease costs, considering the loop "designing, building, testing, redesigning, rebuilding, retesting";Make easier the "what-if" definition and analysis allowing the definition and experimentation and test of CONOPS;De-risk the overall project. To characterize adequately the Satcom link of DeSIRE 2 against the stringent performance requirements of the aeronautical context, an intensive measurement campaign is required. Concerning flight, the testing hours for a large RPAS are very costly. Therefore, it has been decided to add to the experimental flight campaign a combination of simulated and emulated environments, which replicate, as much as possible, the real operational conditions. The models used in the simulation will be refined during the iterations, increasing the robustness and reliability, thus, making available results otherwise difficult, costly and even dangerous to be experiment directly in the real world. An overview of the main expected results and how they should support the European standardisation and regulatory activities in the framework of the Air Traffic Insertion ATI, especially for the definition of future satellite-based command & control datalinks, will be given as well. The paper will explain how the project intends to characterise the Satcom command and control datalinks for both Ka and L frequency bands. It will be described how the threefold simulation/emulation/flight campaign approach will be followed to demonstrate that the system meets or exceeds the design requirement by combining:Mission Simulation, including satcom, airborne, mission applications and combination of the above segments;Satcom Emulation with real satellite full communication and RPA/RPS simulators.Mixed simulation and emulation will also be considered and real hardware will be introduced in the simulation loop e.g. real satellite transponders and on board satcom terminals;Flight Campaign. At any stage of this iteration, the results will be fed-back into the simulation/emulation chain. For example, the measured jitter and error rates will be introduced to update the parameters for the simulators for more trustworthy results.

A Near-Term, High-Confidence Heavy Lift Launch Vehicle

Abstract: The use of well understood, legacy elements of the Space Shuttle system could yield a near-term, high-confidence Heavy Lift Launch Vehicle that offers significant performance, reliability, schedule, risk, cost, and work force transition benefits. A side-mount Shuttle-Derived Vehicle (SDV) concept has been defined that has major improvements over previous Shuttle-C concepts. This SDV is shown to carry crew plus large logistics payloads to the ISS, support an operationally efficient and cost effective program of lunar exploration, and offer the potential to support commercial launch operations. This paper provides the latest data and estimates on the configurations, performance, concept of operations, reliability and safety, development schedule, risks, costs, and work force transition opportunities for this optimized side-mount SDV concept. The results presented in this paper have been based on established models and fully validated analysis tools used by the Space Shuttle Program, and are consistent with similar analysis tools commonly used throughout the aerospace industry. While these results serve as a factual basis for comparisons with other launch system architectures, no such comparisons are presented in this paper. The authors welcome comparisons between this optimized SDV and other Heavy Lift Launch Vehicle concepts.

Validating a method for enhanced communications and situational awareness at the incident command level

Abstract: : The availability and interoperability of communications at an incident scene have long been recognized as high-priority problems that need to be addressed to improve our nation's Homeland Security and preparedness. This thesis describes a proposed methodology to address these issues at the Incident Command level while enhancing situational awareness and information sharing. The thesis analyzes the results of a research project funded by the Department of Homeland Security at the University of Louisville's IT Research Center for Homeland Security. The problem being addressed is that the decision-maker with the boots on the ground, the Incident Commander, needs relevant information in the early stages of the emergency at the incident scene and an efficient way to communicate with other resources. The research project fielded a prototype solution based on readily available commercial off-the-shelf components integrated in a man-portable configuration to provide maximum flexibility, lower costs, and ease of operations. A proposed concept of operations in various prevention and response environments was also recommended in the thesis after analyzing the results of several field exercises and interviews with users.
