Final Report Summary - VFF (Holistic, extensible, scalable and standard Virtual Factory Framework)



Executive Summary:

Manufacturing is a dynamic socio-technical system, which is operating in a turbulent environment. Changes are normal and continuous at all levels and the competition is forcing manufacturers to improve the quality, reduce the delivery time and lower the cost. The approach presented in VFF supports the manufacturing enterprises to face these challenges. The project uttermost objective is to foster and strengthen the primacy of Future European Manufacturing by defining the next generation Virtual Factory Framework. The VFF will promote major time and cost savings while increasing performance in the design, management, evaluation and reconfiguration of new or existing facilities, supporting the capability to simulate dynamic complex behaviour over the whole life cycle of Factory, approached as a complex long living Product. Thus the project will research and implement the underlying models and ideas at the foundation of a new conceptual framework designed to implement the next generation Virtual Factory, also meant to lay the basis for future applications in this research area.

VFF is a research project that aims to the Holistic, extensible, scalable and standard Virtual Factory Framework.

VFF promotes major time and cost savings increasing performance in the design, management, evaluation and reconfiguration of new or existing facilities, supporting the capability to simulate dynamic complex behavior over the whole life cycle of Factory, approached as a complex long living Product.

VFF supports the deployment of a next generation Virtual Factory promoting the EU manufacturing competitiveness. It’s based on four pillars which collaboration leads to the realization of the Virtual Factory concepts.

In VFF project (n° 228595, funded by the EC) perspective, the extended enterprise is called Virtual Factory Framework (VFF). It can be defined as “An integrated collaborative platform aimed at facilitating the sharing of resources, manufacturing information and knowledge, while supporting the design and management of all the factory entities, from a single product to networks of companies, along all the phases of the their lifecycles”

The main idea is related to the possibility to realise in parallel to a physical plant also its virtual representation in order to have a place for making all kind of tests before the real plant is completed and, then, without interfering with its operations.

The Virtual Factory (VF) concept has various definitions depending on viewpoints and perspectives, in this paper VF is defined as a VR environment (VRE) that provides, trough the integration of other IT tools, a transparent description and simulations of a real factory to users who could even be separate in time or space by the real entity. In literature such environments are also called Digital Factory or Virtual Manufacturing.

The VF can support the design and management of a production environment by addressing various key issues like:

(a) Reduction of production times and material waste thanks to the analysis of virtual mock-ups,
(b) Development of a knowledge repository where people can find stored information in different versions, with both advisory role and support to the generation of new knowledge,
(c) Improvement of workers efficiency and safety through training and learning on virtual production systems,
(d) Creation of a collaboration network among people concurrently working on the same project in different places.

In order to orchestrate and synchronise the whole amount of data and knowledge produced by the factory applications and to provide them to the VF interoperability platform is needed.

Jointly with introduction of software tools in the Factory the problem of interoperability among various tools is arisen. Several example of framework are available. Since not just the data have to be exchanged by the applications but, where possible, also the knowledge, in the last year the interoperability framework are more and more looking to the potentiality offered by the semantic web technology.

Project Context and Objectives:

Manufacturing has to cope with a more and more complex and evolving market environment: on the one hand the world crisis breaks the balance between demand and production, on the other hand the globalised market pushes for a continuous change. In this context, the ManuFuture technology platform has already proposed some activities to enable the transformation of European Manufacturing Industry into a knowledge based sector capable of competing successfully in the globalized marketplace (ManuFuture 2006). The ManuFuture vision identify the following priorities to reach future competitiveness and sustainability: development of new high-added-value products and services, new business models, new manufacturing engineering, emerging manufacturing science and technologies and transforming R&D and educational infrastructures. Herein the presentation of the new research project titled “Holistic, extensible, scalable and standard Virtual Factory Framework” - VFF (FP7-NMP-2008-3.4-1) highlights its answers to these requirements.

The market proposes new software tools to help the enterprises in facing new market needs (e.g. Siemens PLM solutions and Delmia), but usually only big companies can afford the large investments required by these tools. Therefore, small and medium enterprises (SMEs) are still looking for successful customised and less expensive solutions, which are more suitable for their size and needs.

Innovative methodologies and technologies should influence enterprise strategies, product development and production processes. The Virtual Factory (VF) paradigm, can assist to answer to this need for innovation by addressing several key issues:

• Collaboration among people working on the same project in different places but at the same time.
• Reduction of production times and material waste thanks to the analysis of virtual mock-ups of new products.
• Development of a knowledge repository that is a common place where people can find any kind of stored material (designs or documents) in different versions.
• Creation of a common working place for collaborating in remote situation where members of a network act and operate on various stages of the same production chain.
• Improvement of workers efficiency and safety through training and learning on virtual production systems.

In achieving these objectives new and innovative methods, technologies and tools have to be employed in planning and permanently optimizing the factory operations and its corresponding manufacturing processes. The previous experiences, both from the research and industrial side, result to be not fully efficient because they aim only at partially innovating the factory processes and the integration with the pre-existent ones is difficult. Information Technology infrastructures or new technologies are too expensive for SMEs because of investment and/or management costs. On one hand, there is need for more and more complex production systems with diverging target systems requiring extensive upstream production planning at the highest resolution; on the other hand, the time frame for the planning process is decreasing and existing tools are complex and expensive.

The Virtual Factory consists in an integrated simulation environment that considers the factory as a whole and provides an advanced planning, decision support and validation capability. The Virtual Factory Framework (VFF) implements the framework for an object oriented collaborative virtualised environment, representing a variety of factory activities meant to facilitate the sharing of factory resources, manufacturing information and knowledge. The VFF promotes major time and cost savings while improving collaborative design, management, evaluation and reconfiguration of new or existing facilities. This requires the capability to simulate dynamic complex behavior over the whole life cycle of the Factory that is considered as a complex and long living product. The VFF approach identifies four key research pillars that must be addressed:

I. Reference Model. The Reference Model for factory planning is based on the development of two key concepts: the “factory as a product” and the “non-linear non-deterministic planning methodology”. The Reference Model establishes a coherent standard extensible data-model at the base of the common representation of Factory Objects.
II. VF manager. The VF manager handles the common space of abstract objects representing the Factory. This representation is based on the standard data model.
III. VF modules. The VF modules are the decoupled functional modules that implement the various tools and services for the Factory design, evolution, evaluation, management, etc. They all operate on the same common space of abstract objects.
IV. Knowledge. Knowledge is the engine for the VFF Concept and it has to support the modelling of a wider range of complex systems and provide greater comprehension of modelled the phenomenon.

The collaboration of the four pillars leads to the realization of the Virtual Factory concepts. The Factory Data Model formalises the information generating an overall picture of the factory together with its characteristics, allowing the modelling and handling of data on real-time. The data used for the development of the Data Model is stored in the Knowledge Repository, where it can be further exploited. The VF Manager Core supervises the common space of the framework, ensuring that all pillars, together with their respective components and actors, interact smoothly.

The Virtual Factory, deployed according to the VFF concept, will be permanently synchronised with the Real Factory to achieve time and cost savings in the design, ramp-up, management, evaluation and reconfiguration of the Real Production itself. The Real Factory, interacting in terms of feedbacks and of data needed to set-up and up-date the simulation system, closes the loop. The need of verifying the impact of the VFF approach on the Real Factory asks for the cooperation of industrial partners to define demonstration scenarios that aim at testing and validating the proposed framework. Within the project four demonstration scenarios have been formulated by pairing different factory planning processes and industrial sectors:

1. The first scenario deals with the Factory Design and Optimisation in the machining sector. The VFF tools will be used to design (or re-design) the factory, aiming at higher solution efficiency and effectiveness, and to optimize the configuration of the production systems. This scenario is developed with the cooperation of the industrial partners Compa S.A. and Ficep S.p.A.
2. The second scenario addresses the Factory Ramp-up and Monitoring in the automotive and aerospace sectors.

The VFF tools will enhance the capability to monitor the real factory and improve the set-up activities during the ramp-up phase. Volkswagen Autoeuropa and Alenia Aeronautica S.p.A. are the industrial partner involved in the second scenario.

3. The third scenario faces the Factory Reconfiguration and Logistics in the Automotive and white-goods sectors.

The factory reconfiguration decisions can be supported by simulation and optimization tools, whereas logistics decisions need VFF tools to efficiently face variable demand by means of flexible networked operations. This scenario will be developed with the support of the industrial partners Audi Hungaria Motor Kft. and Frigoglass S.A.I.C.

4. The final scenario called “Next Factory” aims at demonstrating the applicability of the VFF on the entire factory life-cycle. This integrated scenario focuses on the wood-working sectors thanks to the contribution of Homag AG.

Project Results:

The schema in the annex called VFF Framework Brochure shows the architecture of the main result of the project.

Since digital manufacturing technology has become the most important tool for companies to enhance the competitiveness of their products, the Virtual Factory Framework aims at create a standard able to connect different layers of a factory, probably the most effective path to be followed to enhance manufacturing productivity.

Data and Knowledge coming from different industrial domains and processes converge in the shared Data and Knowledge Repository. The common Virtual Factory Data Model assures a comprehensive vision of the information and the possibility to share it with different actors along the factory life-cycle.

The shared Data and Knowledge Repository is governed by the Semantic Virtual Factory Manager (VFM) that provides an open integration platform representing a common and shared communication layer between already existing and newly developed software tools to support the factory design and management. It provides the functionalities of access control, data versioning and selective data query.

The Decoupled Virtual Factory modules are software tools and applications used to support specific activities in the product/process/factory life-cycles. They are listed here below and in pdf in Annex called VFF Modules. These modules are integrated in the framework and can access and modify the shared factory data thanks to the services provided by the VFM.

Finally, the shared data repository can be synchronized with the Real Factory thanks to the Factory Image module, thus closing the loop with the External Data & Knowledge.

Factory Templates – FT INESC

Scope and Goals

This tool can be seen as an intuitive Knowledge Management system, which allows not only seeking information, consistent with the context in study, but also reusing this information. Moreover, it supports the improvement of the activities that are considered the bottlenecks of the processes and finally stores the changes made in Knowledge Repositories Systems oriented to factory life-cycle structuring, in order to make it available to all workers and partners of the company.

Due to the capability of continuously monitor the behaviour of the factory and project the future performance of the system in study, the Factory Template Framework make it possible to analyse if the factory performance is in the desired direction. If not, it enables managers to understand the reasons why it is not, and the corrective actions that should be done.

Approach

To allow the achievement of this significant advantage, Factory Templates architecture is divided into two main modelling perspectives, static and dynamic. The static perspective enables the application of the “Factory as a Product” paradigm (simultaneous/concurrent engineering). On the other hand, the dynamic perspective has as main advantage the continuous factory life-cycle evaluation. With this component, the Factory Templates make it possible to follow and improve processes, detecting bottlenecks.

Performance Measurement Dashboard – PMD INESC

Scope

Nowadays, companies have a huge amount of data stored within different sources along the factory. Hence, Performance Measurement Systems (PMSs) have been developed aiming to support decision-makers by gathering, processing and analysing quantified information on performance and presenting it in a succinct format.

Goals

Potential Impact:

VFF outcomes of the project will have substantial impact on the promotion of strategic targets of the European Economy and Society. These targets regard mainly the competitiveness of European industry, the employment, the environment and the quality of life.

The main output of the project is a fully functional platform, which will be developed upon a completely novel paradigm using the semantic web approach to store the data of the entire Factory in a unique repository with a common data model.

In this economic crisis period the companies that are in danger are mainly the small and medium ones. If the big companies can rely on diversification of investment and consequently possibility of facing difficulties, the SMEs normally cut the innovation amount focusing on the production as it is.

But Factory is a complex system including many different activities. Nowadays each activity along the entire product life cycle inside the factory is handled one by one with different applications each one developed by different ICT company, using his own language and platform for saving data. Information generated by a department must be treated by the following production step and it’s crucial that all the software and tools inside the factory can access to the information.

Despite Interoperability in a factory is essential, it’s still a vision.

The impact on SME is two-fold. On one side, the democratization of the VF will open the access to those tools for manufacturing SMEs, making them benefit from the mentioned advantages. On the other side, the main goal is also to bring new and dynamic KI-SME (Knowledge Intensive SMEs), which are IT solution providers, from “high-tech” to “high-impact”, that also imply a rapid transformation of science results to markets applications

Challenge of the VFF consists in the innovative integration of product, process and factory domains and related data in a unique Data Repository, using a common Data Model. This can empower the productivity of the enterprise lowering the costs for treating the entire cycle.

The use of new technologyes and in particoular Virtual Reality linked with simulation, facilitate the design of a new production line optimizing the row materials flow avoiding possible bottle necks among different machines.

A VIRTUAL representation of the FACTORY can empower the synchronization with the real one. It can promote cost savings in the implementation of new manufacturing sites or reconfiguration of existing ones thanks to the effective virtual representation of building, resource, process, and product.

Impact and avantages of the VFF results are listed below:

Reduction of adaptation and reconfiguration time: The virtual factory framework will provide consistency over the planning and design process by providing a mutually accessible “information market place” for results and assumptions of all planning objects, synchronizing both services and virtual model via a generic modelling language. This information market place will overcome the isolation of the individual planning tasks and simulation tools, reducing adaption and reconfiguration time.

Reduction of ramp-up phase: Project's virtual factory framework and applications target at improving the simulation of real factory activities. This has a beneficial impact to the ramp-up phase since production processes and logistics will have been previously virtually evaluated and validated, consequently, ramp-up phase will become shorter in time.

Time to market: The time to market of a new product is highly dependent upon different factors such as product and process design, supplier selections, commissioning and ramp-up. VFF framework and his different modules aims at improving all the factors mentioned above able to reduce the time to market (because of synchronisation and parallelisation of process steps). Furthermore management of complex automation data within the virtual factory will provide further support of New Product Development and thus reducing time to market.

Customer satisfaction and market share: Customer satisfaction has been increased by improving product quality by optimizing the production processes (reducing costs by avoiding rework, speed up the ramp up and increased flexibility and reactivity) and by reducing delivery times through improved management of the suppliers and production network (especially in the case of complex products such as vehicles).

Beside the framework and its advantages, results of the project also a number of software modules and tools able to intervene on specific steps of the production. The tools are listed above and we proved their efficacy using them in the industrial scenarios.

The industrial partners and the technology provider in VFF are recognized key global players and leaders in their respective sectors, as described in the following paragraph. Thus, the Consortium will have a clear cross-national and worldwide character and impact.
