Applications integration for manufacturing control systems with particular reference to software interoperability issues
The introduction and adoption of contemporary computer aided manufacturing control
systems (MCS) can help rationalise and improve the productivity of manufacturing related
activities. Such activities include product design, process planning and production
management with CAD, CAPP and CAPM. However, they tend to be domain specific and
would generally have been designed as stand-alone systems where there is a serious lack of
consideration for integration requirements with other manufacturing activities outside the area
of immediate concern. As a result, "islands of computerisation" exist which exhibit
deficiencies and constraints that inhibit or complicate subsequent interoperation among typical
MCS components. As a result of these interoperability constraints, contemporary forms of
MCS typically yield sub-optimal benefits and do not promote synergy on an enterprise-wide
basis.
The move towards more integrated manufacturing systems, which requires advances in
software interoperability, is becoming a strategic issue. Here the primary aim is to realise
greater functional synergy between software components which span engineering, production
and management activities and systems. Hence information of global interest needs to be
shared across conventional functional boundaries between enterprise functions.
The main thrust of this research study is to derive a new generation of MCS in which
software components can "functionally interact" and share common information through
accessing distributed data repositories in an efficient, highly flexible and standardised
manner. It addresses problems of information fragmentation and the lack of formalism, as
well as issues relating to flexibly structuring interactions between threads of functionality
embedded within the various components. The emphasis is on the:
⢠definition of generic information models which underpin the sharing of common
data among production planning, product design, finite capacity scheduling and cell
control systems.
⢠development of an effective framework to manage functional interaction between
MCS components, thereby coordinating their combined activities.
⢠"soft" or flexible integration of the MCS activities over an integrating infrastructure
in order to (i) help simplify typical integration problems found when using
contemporary interconnection methods for applications integration; and (ii) enable
their reconfiguration and incremental development. In order to facilitate adaptability in response to changing needs, these systems must also be
engineered to enable reconfigurability over their life cycle. Thus within the scope of this
research study a new methodology and software toolset have been developed to formally
structure and support implementation, run-time and change processes. The tool set combines
the use of IDEFO (for activity based or functional modelling), IDEFIX (for entity-attribute
relationship modelling), and EXPRESS (for information modelling).
This research includes a pragmatic but effective means of dealing with legacyl software,
which often may be a vital source of readily available information which supports the
operation of the manufacturing enterprise. The pragmatism and medium term relevance of the
research study has promoted particular interest and collaboration from software manufacturers
and industrial practitioners. Proof of concept studies have been carried out to implement and
evaluate the developed mechanisms and software toolset
The impact of enterprise application integration on information system lifecycles
Information systems (IS) have become the organisational fabric for intra-and inter-organisational collaboration in business. As a result, there is mounting pressure from customers and suppliers for a direct move away from disparate systems operating in parallel towards a more common shared architecture. In part, this has been achieved through the emergence of new technology that is being packaged into a portfolio of technologies known as enterprise application integration (EAI). Its emergence however, is presenting investment decision-makers charged with the evaluation of IS with an interesting challenge. The integration of IS in-line with the needs of the business is extending their identity and lifecycle, making it difficult to evaluate the full impact of the system as it has no definitive start and/or end. Indeed, the argument presented in this paper is that traditional life cycle models are changing as a result of technologies that support their integration with other systems. In this paper, the need for a better understanding of EAI and its impact on IS lifecycles are discussed and a classification framework proposed.Engineering and Physical Sciences Research Council (EPSRC) Grant Ref: (GR/R08025) and Australian Research Council (DP0344682)
Special section Industry 4.0: Challenges for the future in manufacturing
International audienceThe sensing enterprise is a digital business innovation concept making Cyber-Physical Systems, service-oriented architectures and advanced human-computer interactions converge, supporting a more agile, flexible, and proactive management of unexpected events in todayâs global value networks. In essence, it concerns the adoption of future Internet technologies in virtual enterprises. Translating this concept to a general approach to smart systems (smart manufacturing, smart cities, smart logistics, etc.), requires new capabilities by next-generation information systems to perform sensing, modelling, and interpretation of âanyâ signal from the real world, thus providing the systems with higher flexibility and possibilities for reconfiguration (Panetto et al. 2016). Intuitively, a sensing system requires resources and machineries to be constantly monitored, configured, and easily controlled by human operators. All these functions, and much more indeed, are now implemented by the so-called (Industrial) Internet of Things or Cyber-Physical Systems. With the advent of the new cyber-physical system design paradigm, the number and diversity of systems that need to work together in the future enterprises have significantly increased (Weichhart et al. 2016). This trend highlights the need to shift from the classic central control of systems, towards systems interoperability as a capability to control, sense, and perceive distributed and heterogeneous systems and their environments, as well as to purposefully and socially act upon their perceptions. Such a shift could have important consequences on the future architecture design of the control of these systems. The emergence of cloud-based technologies will also have a significant impact on the design and implementation of cyber-physical systems; using such novel technologies, collaborative engineering practises will increase globally, thus enabling a new generation of small-scale industrial organizations to function in an information-centric manner and enabling industry 4.0 transformations (Cimini, et al, 2017). The potential of such technologies in fostering a leaner and more agile approach towards engineering is very high. Engineers and engineering organizations no longer have to be restricted to the availability of advanced processing capabilities, as they can adopt a âpay as you goâ approach, which will enable them to access and use software resources for engineering activities from any remote location in the world

Exploring knowledge management integration through EAI in local government domain
Information Technology (IT) infrastructure integration and knowledge management share communal objectives e.g. to make organisations more effective and efficient, agile and innovative, and more responsive to market changes. Such association when assimilates bona fide knowledge management philosophy, it offers the IT departments a headship opportunity for organisational transformation in affiliation with the rest of the establishment. Notwithstanding, in the context of Local Government Authorities (LGAs), the non-integrated nature of the IT infrastructure is associated with inefficient data and knowledge exchange and reduction in LGA servicesâ quality. Therefore, numerous data inconsistencies and redundancies occur that impact LGA services to their citizenry. LGAs have deployed Enterprise Application Integration (EAI) technological solutions to integrate their legacy with new developed Information Systems (IS). Literature indicates that EAI achieves integration at five layers namely: (a) connectivity, (b) transportation, (c) transformation, (d) process integration and (e) knowledge integration. This research adapts a Revised Model for Integration Layers (REAL) and tests through a case study in a local authority. The results indicate that cases leading to data inconsistencies and replication can be prevented by integrating knowledge through EAI

Towards a flexible service integration through separation of business rules
Driven by dynamic market demands, enterprises are continuously exploring collaborations with others to add value to their services and seize new market opportunities. Achieving enterprise collaboration is facilitated by Enterprise Application Integration and Business-to-Business approaches that employ architectural paradigms like Service Oriented Architecture and incorporate technological advancements in networking and computing. However, flexibility remains a major challenge related to enterprise collaboration. How can changes in demands and opportunities be reflected in collaboration solutions with minimum time and effort and with maximum reuse of existing applications? This paper proposes an approach towards a more flexible integration of enterprise applications in the context of service mediation. We achieve this by combining goal-based, model-driven and serviceoriented approaches. In particular, we pay special attention to the separation of business rules from the business process of the integration solution. Specifying the requirements as goal models, we separate those parts which are more likely to evolve over time in terms of business rules. These business rules are then made executable by exposing them as Web services and incorporating them into the design of the business process.\ud
Thus, should the business rules change, the business process remains unaffected. Finally, this paper also provides an evaluation of the flexibility of our solution in relation to the current work in business process flexibility research

Towards a methodology for the development of integrated IT infrastructures
In this paper, the authors propose and validate
a methodology for the development of integrated
Information Technology (IT) infrastructures. The
motivation for putting forward a new methodology is
grounded on the limitations of the various software
engineering methodologies (traditional) that exist
today. Despite that the traditional methodologies result
in the development of Information Systems (IS) from
scratch, Enterprise Application Integration (EAI)
builds integrated IT infrastructures using existing
applications. This significant difference is associated
with many issues needed to be realised and addressed
like: (a) the changes that such an infrastructure brings
to organisations, (b) the resistance to change and (c)
the extension of IS lifecycleâs. The proposed
methodology consist of eight stages and aims at
supporting software engineers, organisations and
researchers to build integrated IT infrastructures. As a
result the methodology seeks to contribute to the body
of knowledge
