Today companies don’t have time and resources availability to stop their production to evaluate new layout and strategies, unless the results are guaranteed. Developing or redesigning products, gathering them in a product family and creating product platforms can be expensive tasks that represent a meaningful outlay for companies if they don’t have the adequate tools in order to facilitate the work. Thus, it is important to define the most appropriate manufacturing system as well as the performance of the chain value and the equipment layout in order to achieve an optimal production with the best quality and the shortest times and production costs. Therefore, computational tools, validated by working strategies and philosophies as Lean Manufacturing (LM) and Product Lifecycle Management (PLM) become necessary. After the evaluation of products, the value chain and the layout, these tools allow the construction of models and simulations as dynamic Value Stream Map (dynamic VSM), to analyze the actual process functioning or future process plans and PLM software, to estimate production flows, equipment and human labor requirements without stopping the normal production activities and providing competitive advantages to the company.

Abstract Product Lifecycle Management (PLM) ranges from design concepts of products to disposal. In this paper, we focus on the production planning phase in PLM, which is related to process planning and production scheduling and so on. In this study, key decisions for the creation of production plans are defined as production-planning attributes. Production-planning attributes correlate complexly in production-planning problems. Traditionally, the production-planning problem splits sub-problems based on experiences, because of the complexity. In addition, the orders in which to solve each sub-problem are determined by priorities between sub-problems. However, such approaches make solution space over-restricted and make it difficult to find a better solution. We have proposed a representation of combinations of alternatives in production-planning attributes by using Zero-Suppressed Binary Decision Diagrams. The ZDD represents only feasible combinations of alternatives that satisfy constraints in the production planning. Moreover, we have developed a solution search method that solves production-planning problems with ZDDs. In this paper, we propose an approach for managing solution candidates by ZDDs' network for addressing larger production-planning problems. The network can be created by linkages of ZDDs that express constraints in individual sub-problems and between sub-problems. The benefit of this approach is that it represents solution space, satisfying whole constraints in the production planning. This case study shows that the validity of the proposed approach.

Testo completoAbstract (sommario):
The past three decades have seen phenomenal growth in investments in the area of product lifecycle management (PLM) as companies exploit opportunities in streamlining product lifecycle processes, and fully harnessing their data assets. These processes span all product lifecycle phases from requirements definition, systems design/ analysis, and simulation, detailed design, manufacturing planning, production planning, quality management, customer support, in-service management, and end-of-life recycling. Initiatives ranging from process re-engineering, enterprise-level change management, standardization, globalization and the like have moved PLM processes to mission-critical enterprise systems. Product data representations that encapsulate semantics to support product data exchange and PLM collaboration processes have driven several standards organizations, vendor product development efforts, real-world PLM implementations, and research initiatives. However, the process and deployment dimensions have attracted little attention: The need to optimize organization processes rather than individual benefits poses challenging “culture change management” issues and have derailed many enterprise-scale PLM efforts. Drawn from the authors’ field experiences as PLM system integrators, business process consultants, corporate executives, vendors, and academicians, this paper explores the broad scope of PLM, with an added focus on the implementation and deployment of PLM beyond the development of technology. We review the historical evolution of engineering information management/PLM systems and processes, characterize PLM implementations and solution contexts, and discuss case studies from multiple industries. We conclude with a discussion of research issues motivated by improving PLM adoption in industry.

Testo completoAbstract (sommario):
Product lifecycle management (PLM) as a holistic process encompasses the idea generation for a product, its conception, and its production, as well as its operating phase. Numerous tools and data models are used throughout this process. In recent years, industry and academia have developed integration concepts to realize efficient PLM across all domains and phases. However, the solutions available in practice need specific interfaces and tend to be vendor dependent. The Asset Administration Shell (AAS) aims to be a standardized digital representation of an asset (e.g., a product). In accordance with its objective, it has the potential to integrate all data generated during the PLM process into one data model and to provide a universally valid interface for all PLM phases. However, to date, there is no holistic concept that demonstrates this potential. The goal of this research work is to develop and validate such an AAS-based concept. This article demonstrates the application of the AAS in an order-controlled production process, including the semi-automatic generation of PLM-related AAS data. Furthermore, it discusses the potential of the AAS as a standard interface providing a smooth data integration throughout the PLM process.

Smaller Companies are discovering that product management tools can help their small staffs get a global reach. The Product Lifecycle Management (PLM) software has become an important tool for managing people and resources at enterprises of any size. At Sonnax, the adoption of a PLM solution has led to some clear changes in information management. Instead of relying on a single point-person to do the project management for the whole company, each product line sales manager has become more deeply involved in the designs of specific lines. Indeed, many startups are incorporating PLM solutions before they even have products to manage. One factor that may be pushing small- and medium-size enterprises to adopt PLM solutions is the new globalized business model. Experts see PLM as way to help the far-flung pieces of the production chain mesh together. The system can be set up to enable suppliers of components anywhere in the world to look at the documentation they need, and to determine the most relevant information: what the history was, the nature of the changes, who approved it, and so forth.

Testo completoAbstract (sommario):
This article discusses the future of software that links engineering and manufacturing. Companies are seeking a natural link between engineering and manufacturing, even if some aspects of it may be restricted. According to experts, giving manufacturers direct access to that design information would help them isolate potential manufacturing problems earlier in the cycle, cut product development time by stepping up design-manufacturing communication, and ensure that products will comply with government regulations. The article also describes that by allowing for quick communication and updates to an already existing computer-aided design model, product lifecycle management (PLM) can help speed these products to market. Engineers are putting efforts to bring PLM information to the factory floor to cut production time. Though the day of easy integration has yet to arrive, many companies are using PLM to reduce cycle time. Pushing PLM to the factory floor would help, according to an engineer. However, that's not an option for many until integration software comes to the fore.

Fault diagnosis presents a considerable difficulty to human operators in supervisory control of manufacturing systems. Implementing Internet of Things (IoT) technologies in existing manufacturing facilities implies an investment, since it requires upgrading them with sensors, connectivity capabilities, and IoT software platforms. Aligned with the technological vision of Industry 4.0 and based on currently existing information databases in the industry, this work proposes a lower-investment alternative solution for fault diagnosis and problem solving. This paper presents the details of the information and communication models of an application prototype oriented to production. It aims at assisting shop-floor actors during a Manufacturing Problem Solving (MPS) process. It captures and shares knowledge, taking existing Process Failure Mode and Effect Analysis (PFMEA) documents as an initial source of information related to potential manufacturing problems. It uses a Product Lifecycle Management (PLM) system as source of manufacturing context information related to the problems under investigation and integrates Case-Based Reasoning (CBR) technology to provide information about similar manufacturing problems.

The high cost and long lead times of traditional manufacturing makes it difficult for manufactures to efficiently meet eternally changing market demands. In order to determine the manufacturability of the component and low cost production of aircraft manufacturing, Digital Virtual Manufacturing plays a vital role. By the advancement in technologies like Virtual Manufacturing tools used through Product Lifecycle Management (PLM), are competent to access and reuse the best practices, as well as evaluate 3-D manufacturing scenarios. By implementing advance 3-D CAD systems with the CNC machines enables the success of the determinate assembly approach to significantly reduce the lead time aircraft manufacturing. This paper encompasses the virtual manufacturing concept to enable complex manufacturing set-up analysis, exchanging expertise at collaborative work. Virtual Manufacturing is using the manufacturing knowledge at PLM environment for defining the assembly process of an aircraft parts.

The paper deals with optimization of the production process in a selected company. The proposal of elimination of bottlenecks that were revealed in the analysis of the production process is described here in this paper. For clarity and zooming of the production process models were processed in a simulation software module from Siemens PLM Software - Tecnomatix Plant Simulation. Improvement suggestions will help to reduce the time of production operations, to improve product quality, to facilitate the work of the staff and to increase economic efficiency of production. The application of PLM software enables companies to analyze and easily develop manufacturing processes in the future, or to build new processing lines and departments [4]. It will help to optimize the current state of workplace and will allow easier data management throughout the life cycle, not just within this particular company, but throughout the corporation to which the enterprise belongs.

Testo completoAbstract (sommario):
The production of energy in wind power plants is regarded as ecologically clean because there being no direct emissions of harmful substances during the conversion of wind energy into electricity. The production and operation of wind power plant components make use of the significant potential of materials such as steel, plastics, concrete, oils, and greases. Energy is also used, which is a source of potential negative environmental impacts. Servicing a wind farm power plant during its operational years, which lasts most often 25 years, followed by its disassembly, involves energy expenditures as well as the recovery of post-construction material potential. There is little research in the world literature on models and methodologies addressing analyses of the environmental and energy aspects of wind turbine modernization, whether in reference to turbines within their respective lifecycles or to those which have already completed them. The paper presents an attempt to solve the problems of wind turbine modernization in terms of balancing energy and material potentials. The aim of sustainable modernization is to overhaul: assemblies, components, and elements of wind power plants to extend selected phases as well as the lifecycle thereof while maintaining a high quality of power and energy; high energy, environmental, and economic efficiency; and low harmfulness to operators, operational functions, the environment, and other technical systems. The aim of the study is to develop a methodology to assess the efficiency of energy and environmental costs incurred during the 25-year lifecycle of a 2 MW wind power plant and of the very same power plant undergoing sustainable modernization to extend its lifecycle to 50 years. The analytical and research procedure conducted is a new model and methodological approach, one which is a valuable source of data for the sustainable lifecycle management of wind power plants in an economy focused on process efficiency and the sustainability of energy and material resources.

Testo completoAbstract (sommario):
Technologies of the Electronics Product Definition - EPD, Product Data Management - PDM and Product Lifecycle Management - PLM represent modern trends in the field of Technical Production Planning and a new quality in this sector. Efficiency of utilization of these technologies for specific manufacturing companies depends materially on correct selection of the system and correct user adaptation of the purchased technologies. The main problem in CR is that the companies do not have adequate knowledge of the issue and therefore the conceptual system of selection does not exist here. And this is why the situation of selection is based as follows: The company addresses the supply house with unclear requirements, is unable to be adequately depth-oriented and selection of the system is in principle carried out by the addressed supply house which results in the danger that the company introduces an expensive system not quite conforming to its character. Instead of the awaited effect the total costs continue rising materially. The methodology of selection of the PDM system should be designed so that the whole process of selection is managed by the company itself and is modified precisely to its requirements. This is the very topic of this paper.

Systems 8, n. 4 (10 novembre 2020): 43. http://dx.doi.org/10.3390/systems8040043.
Testo completoAbstract (sommario):
Additive manufacturing (AM) opens the vision of decentralised and individualised manufacturing, as a tailored product can be manufactured in proximity to the customers with minimal physical infrastructure required. Consequently, the digital infrastructure and systems solution becomes substantially more complex. There is always a need to design the entire digital system so that different partners (or stakeholders) access correct and relevant information and even support design iterations despite the heterogenous digital environments involved. This paper describes how the design and integration of a digital thread for AM can be approached. A system supporting a digital thread for AM kayak production has been designed and integrated in collaboration with a kayak manufacturer and a professional collaborative product lifecycle management (PLM) software and service provider. From the demonstrated system functionality, three key lessons learnt are clarified: (1) The need for developing a process model of the physical and digital flow in the early stages, (2) the separation between the data to be shared and the processing of data to perform each parties’ task, and (3) the development of an ad-hoc digital application for the involvement of new stakeholders in the AM digital flow, such as final users. The application of the digital thread system was demonstrated through a test of the overall concept by manufacturing a functional and individually customised kayak, printed remotely using AM (composed of a biocomposite containing 20% wood-based fibre).

Testo completoAbstract (sommario):
The article is devoted to the peculiarities of the open operating system (OS) application MindSphere in digital transformation of high-tech enterprises. The theoretical part of the article notes that nowadays digital transformation already has a huge impact on various aspects of business, such as strategy, partner management, production, pricing, sales, promotion, and organizational structure. The main task of the MindSphere platform is to provide fast and cost-effective connection of the equipment fleet, data collection, and analysis in order to obtain significant production and business results. The MindSphere platform integrates all data sources: Product Lifecycle Management (PLM), Enterprise Resource Planning (ERP), Manufacturing Execution Systems (MES), Quality Management Systems (QMS), Customer Relationship Management (CRM) and Internet of Things (IOT) into one analysis center. In the course of the analysis, the authors found that the MindSphere OS allows for the effective unification, search, filtering and evaluation of data taking into account the context, which gives a significant synergetic effect and provides a basis for intelligent decision-making, and therefore significantly reduces the cost and time to find sources of problems, allowing to focus on optimizing products, production and service, considering the creation of value and increase customer satisfaction. The authors point out that the implementation of IOT solutions opens up a new dimension for business owners in the view of their company based on data, and for the company itself provides previously inaccessible speed of operation, transparency of processes and their optimization, also raises the safety of work and other aspects of activity to a new level. In the final part of the article the authors conclude that MindSphere platform has all necessary qualities to be among the leaders of the Industrial IOT (IIOT), to provide customers with the opportunity to qualitatively transform IOT data into useful business results.

The aim of this study is to develop an analytical tool to estimate lifecycle cost for water service provision for small-scale community water projects. The primary objective is to provide an analytical estimation tool to governments, funding agencies and communities to ensure sustainability of water projects. The secondary objective is to use the tool as an industry benchmarking aid to empower governments, funding agencies and technology developers to support technologies that would further lower the cost of water production. The tool firstly considers capital expenditure required for a given water service system, focusing on equipment manufacturing costs in detail. Thereafter, it considers the operational expenditure associated with ongoing functioning of the water treatment plant. The developed tool is validated using five simulation scenarios. Results shows that the tool can be used to evaluate the performance of a water service system even if the water services systems are operated using varying strategies. The developed tool also enables effective decision making by testing alternatives and addressing the water service system lifecycle aspects and, thus, making the cost of water production manageable. This paper also introduces the web version of the tool, which is available to communities, governments, technology developers and funding agencies to use.

The heavy load carrying facility, such as ladle crane, is operating under severe working environment. It usually carries melted iron to the furnace, and thus, the accident due to crane failure may cause detrimental damage to the entire steel making factory. While the ladle crane is designed for 20 years of safe operation in a steel making company, several critical cracks due to fatigue loading have been reported during the maintenance process. In order to prevent fatal failure due to crack growth, ladle crane has been periodically inspected and maintained. However, the inspection and maintenance including repair and replacement cause the whole manufacturing line to stop, it is critical to set the appropriate inspection interval and replacement criteria. For this reason, the importance of plant maintenance (PM) has been highly raised to provide efficient plant operation. Recently, a number of engineering methodologies, such as fitness for service guidelines (FFS) and plant lifecycle management (PLM) system, have been applied to improve the plant operation efficiency. Also, a network-based business operation system, which is called ERP (Enterprise Resource Planning), has been introduced in the field of plant maintenance. However, there hasn’t been any attempt to connect engineering methodologies to the ERP PM(Plant Maintenance) system. In this paper, an engineering methodology which provides life time evaluation under fatigue loading has been implemented to the web-based ERP PM system along with real-time fatigue monitoring system. In order to monitor the real time loading, a web-based fatigue monitoring system for ladle crane has been developed and installed inside the ladle crane. For the estimation of fatigue life, 3-dimensional finite element (FE) analyses were conducted for actual transients. Finally, the fatigue life time estimation program is developed by integrating FE analysis results and real-time monitoring data. For the direct calculation of remained fatigue life, an artificial neural network (ANN) algorithm has been applied. The proposed system is expected to play a great role in determining appropriate inspection and maintenance schedule which has become critical issue for the efficient plant maintenance.

The aim of this manuscript is to define an operational pipeline of work, from data acquisition to the report creation, for the smart management of PV plants. To achieve such an ambitious result, we exploit the implementation of a conceptual model, deployed through a relational database to retrieve any kind of information related to the PV plant. The motivation that drove this research is due to the increasing construction of PV plants. In fact, following European and international investments that heavily stimulated the use of clean energy, the need to maintain PV plants in their maximum efficiency for their whole lifecycle emerged, to bring about benefits from both the ecological and the economic points of view. While the research community focuses on finding new and automatic ways to detect faults automatically, few efforts have been made considering the so-called Operation and Maintenance (O&M). A relational conceptual model may facilitate the management of heterogeneous sources of information, which are common in complex PV plants. The purpose of the present study is to provide companies and insiders with a GIS-based tool to maintain the energy efficiency of a PV plant. Indeed, it is a common practice used by companies dealing with O&M of PV plants to create technical reports about the health status of the plants. This operation, made manually, is very time consuming and error prone. To overcome this latter drawback, this work attempts to encourage the use of GIS in the PV plants O&M, which proves to be efficient to deal with fault management and to assure a good level of energy production. The developed conceptual model, tested on two real case studies, proved to be complete, cost-effective and efficient to be replicated in other existing plants.

With the growth of information technologies in the field of computer-aided design, the concept of CAD acquires new meaning and changes the contents. More and more a new definitions, i.e. Building Information Modeling - BIM, Fabrication Information Modeling - FIM, Integrated Structural Modeling - ISM, Building Lifecycle Management - PLM and others are encountered, the concept of which may be described as way to develop the strategy of building project design, construction, and maintenance management based on the computer aided modeling and simulation technologies. Examine BIM application in building design process it can be assumed that of object modeling and simulation technique comprises a full range of actions starting from the development of virtual model of the project under consideration, describing all physical parameters characteristic of a real structure, defining the conditions of its position. Then analysis of model behavior under real maintenance conditions is performed: effects of different character are described and the results obtained are analyzed. The results received by next step are presented in common technical documentation form: general arrangement and erection drawings are generated, final detailing of connections and structural elements in the form of shop drawing or NC code is performed, bill of materials, cut lists, various reports, specifications and estimates are composed. During the last five years there is strong request from the market for the state-of-the-art computer-aided design applications developed to meet the needs and requirements of the Architectural, Engineering, and Construction as well as Plant, Process, and Power industries, for high performance, flexible and versatile tools with extended graphics integration to simulation and analysis systems within a user-friendly design environment that allows the close emulation of natural design phases and workflow to which structural are accustomed. This could became possible due to the innovative development of ‘new generation’ structural software application capable to maintain an intelligent and true 3D real-world simulated structure containing all the information required for the general and detailed design, fabrication and construction of engineering structures, enabling designers to operate intuitively in the adaptive high-performance real-time visual modeling environment while simultaneously achieving high-quality results by applying powerful simulation, analysis and optimization methods which would guarantee a rational and effective choice of the constructive decision. It has to be flexible to enable external best of breed vertical market products to be linked to the application and hence creating an open design environment; this enables members of a workgroup to collaborate effectively, performing the multiple tasks associated with construction design.

Testo completoAbstract (sommario):
Process, manufacturing, and service industries currently face a large number of non-trivial challenges ranging from product conception, going through design, development, commercialization, and delivering in a customized market’s environment. Thus, industries can benefit by integrating new technologies in their day-by-day tasks gaining profitability. This work presents a model for enterprise process development activities called the wide intelligent management architecture model to integrate new technologies for services, processes, and manufacturing companies who strive to find the most efficient way towards enterprise and process intelligence. The model comprises and structures three critical systems: process system, knowledge system, and transactional system. As a result, analytical tools belonging to process activities and transactional data system are guided by a systematic development framework consolidated with formal knowledge models. Thus, the model improves the interaction among processes lifecycle, analytical models, transactional system, and knowledge. Finally, a case study is presented where an acrylic fiber production plant applies the proposed model, demonstrating how the three models described in the methodology work together to reach the desired technology application life cycle assessment systematically. Results allow us to conclude that the interaction between the semantics of formal knowledge models and the processes-transactional system development framework facilitates and simplifies new technology implementation along with enterprise development activities.

Esso Australia Resources Pty Ltd (EAPL) and BHP Billiton Petroleum (Bass Strait) Pty Ltd own a range of offshore and onshore hydrocarbon production facilities, which have been operated by EAPL for over 50 years. Over this time, EAPL has lived a rich history of process safety experiences, and developed a range of processes and systems to manage process safety risks. Despite technical system refinement and advances across industry we continue to experience process safety events, and manage risks with plant both at the start and end of its lifecycle. Many of our major hazards are inherent to our operations, and do not become lower risk with lower product price or field activity levels. It is therefore critical that we maintain a laser focus on managing process safety risks during this time of unprecedented change, and find impactful opportunities to engage with operations, maintenance and technical teams on their role in process safety. To this end, EAPL have commenced a journey of scenario based process safety management and applying it to our most significant risks. The outcome has been a step change in process safety literacy across our business, an increased awareness of safe operating conditions and a workforce engaged in managing safeguard health. This study shares how a scenario based approach can leverage a traditional safety case and safety management system approach and make process safety personal: Simplifying communication of higher risks and the equipment and processes that keep us safe Clarifying safeguard ownership and responsibilities for safeguard health management Embedding safeguard health management in routine operations and maintenance tasks Strengthening critical safeguards which mostly depend on human performance to be effective

Digitalization is the key trend of the Industry 4.0 revolution. Industrial companies are transforming the way they design and maintain their products and solutions. The user requirements become more demanding. Competition among the manufacturing companies is at its limits and transforms the products to be more complex. Yet, other challenges such as faster time to market, higher quality requirements and legislation force enterprises to provide new ways of design, manufacture and service their end products. Product Lifecycle Management (PLM) is a key solution to track the entire lifespan of the product from idea to design, design to manufacture and manufacture to service. Besides the complexity of products and production, the selection of the right PLM solution which will become the backbone of enterprises is an open problem. In this paper, a thorough literature review is conducted to analyze the most important features for selecting the right PLM solution for manufacturing firms. Moreover, to overcome the challenge of decision makers’ (DM) subjective judgments, a novel interval value spherical fuzzy COPRAS (IVSF-COPRAS) multi-criteria decision making (MCDM) method is introduced. The paper aims to help enterprises rapidly identify the best alternative vendor/solution to be selected based on the need of the organization. In order to show the applicability, DM inputs are collected from a leading defense company where the PLM selection process is ongoing. The industrial case study is provided to demonstrate the success of the proposed selection framework.

Purpose The purpose of this research is to support the customization ability for industrial house building companies striving to offer individualized products but with a strategy which includes a production facility. This is accomplished by analyzing the as-is state in terms of existing engineering assets and by proposing a to-be state using the design platform and product lifecycle management (PLM) support. Design/methodology/approach This study is based on design research methodology and collected data are in-depth interviews, document reviews and workshops and method development. The theoretical baseline is product platforms and the design platform. Findings The analysis showed that despite use of a platform, inherent assets are disorganized. Still, the identified object-based engineering assets were possible to include in a conceptual proposal for better management, both in the process and product view, using an asset relationship matrix and a PLM system. Practical implications The results should be applicable for industrial house building and off-site construction companies and offers an approach to identify and manage their assets and platforms which are crucial to stay competitive. Originality/value Previous research on design platforms has focused on engineer-to-order companies within the mechanical industry. The contribution of this paper lies in the application and support of the design platform for industrial house building and the introduction of PLM system support.

The article presents models of inventory accounting led by a project manager and system engineer. The project “Inventory accounting system using system engineering methods” is aimed at the formation of a separate inventory accounting system in the development, manufacture and production of products. In the framework of Ural Diesel Engine Plant LLC, such records are kept only for expensive components that are delivered with military acceptance in the context of each contract for each state contract. Even with such accounting at the enterprise, there is a problem of making small profits or lack of profit from the manufacture of military diesel generators. In developing my project, I would like to improve the system of accounting and writing off inventory items supplied with military acceptance, and later using this system for the entire list of components that make up the product.
