Manufacturing enterprise integration using hierarchial control and distributed database. Generation of manufacturing tolerancing with ISO standards. A common challenge in the integration of processes, resources, and information exchanges across manufacturing operations within an enterprise involves selecting 155745-1 interfaces to support interoperability of the operations.
By combining the integration approaches of ISO application integration framework and of IEC enterprise-control system integrationa scheme to delineate these interoperability interfaces is proposed. The scheme extends the IEC generic activity model beyond the manufacturing operations management domain and the 15745–1 integration model beyond the operations automation domain.
One approach to integrating these various aspects is to construct an integration model that enables the application developer to distinguish the required interfaces and to state isl the configuration of the interfaces to support interoperability. In this paper, an application hierarchy is considered as a combination of functional and resource hierarchies within an enterprise. The scheme uses the functional hierarchy model defined in IEC The resource hierarchy model used is an extension of 51745-1 IEC equipment hierarchy model, where the materials, the personnel, and other items used in the manufacturing activities are included.
In chapter 2, a manufacturing application hierarchy, based on IECis used to illustrate both the functional iwo resource hierarchies, along with the activity domains and the information structures izo among the resources.
In chapter 3, an application integration scheme, based on Iois described. References to the interfaces and their required settings are organized in profiles. Chapter 5 outlines how a set of application interoperability profiles are used to describe the integration of multiple applications at different levels of a hierarchy. Conclusions and some future work are noted in Isi 6. In the IEC framework IEC, the applications within a manufacturing enterprise are structured as a hierarchy of activity domains, 52 where each level in the hierarchy denotes a group of functions that are performed to support a specific operational level of an enterprise.
In addition, the IEC standard also defines an equipment hierarchy that distinguishes in which physical grouping and at which organizational level a piece of equipment is being used.
Level F2 and below are integrated using the information 157451- and exchanges managed by Level F3 activities, applications, processes, resources, and functions. Examples of Level F3 manufacturing operations management activities include production, maintenance, product quality testing, and material handling. The next level, Level F3, is comprised of the manufacturing operations management activities.
The equipment groupings are also organized by the physical extent of the associated set of activities. A class Area at Level R3 may consist of one or more work centers whose operational nature differs by industry. Equipment hierarchy within an enterprise per IECEnterprise-control system 15754-1.
Functional hierarchy per IECEnterprise-control system integration Operations capability AREA Analysis In the pharmaceutical, food processing and beverage industries, the work center is called a process cell while in the oil and chemical processing industries, a work center is called a production unit.
For the automotive and machining industries, a production line is the work center. In the material handling industries, an example of a work center is a storage zone. Data collection Execution Fig. In this proposed integration scheme, each level within an application hierarchy of an enterprise is denoted either by a resource or a functional level.
A UML class diagram illustrating this composition is shown in Figure 4.

For each application, a set of resources are used to conduct the related processes and to perform the information exchanges. In the proposed scheme given in this paper, the ISO integration framework intended for Level F2 is extended to cover the other levels in an application hierarchy. Further, each type of component integration model consists of a set of UML diagrams to represent both the static and dynamic relationships among the various resources, processes, 155745-1 information exchanges.
For example, a UML sequence diagram is used to represent the transfers of material and information among the devices, equipment, and personnel involved in the process under control.
At the transfer points, the types and number of required interfaces are identified. The selected settings of the interfaces that match the application requirements are expressed in terms isl interoperability profiles, where the templates for the profiles are XML schemas Rec-XML, The integration requirements posed by the manufacturing process include many aspects, such as, the quantities, qualities, sources, destinations, and transfer rates of the items in the flows.
Other aspects, such as, the cost, safety, security, and environmental compatibility to realize the flows are also essential in forming the integration requirements. An integration model of a manufacturing application consists of several aspects – a set of processes with associated sets of resources that perform a set of Manufacturing Application These constraints also relate to the sequence and timing of the information exchanges among the resources.
In Figure 4, the Aggregation relationship is further constrained by the Integration Requirements class.
Resource interoperability profile template per ISOApplication integration framework 4. The collection of the configuration settings for all the required interfaces of a particular resource is captured in an interoperability profile corresponding to the type of resource. ISO defines the standard templates for constructing different types of interoperability profiles. All templates have a common structure, i. A template has an optional integrity signature element to verify the header and body elements in a profile.
For each set of manufacturing resources associated with a particular process, a corresponding set of resource interoperability profiles delineates the full set of interfaces and associated settings to support a particular process. The coordination of the resources to enable the manufacturing process execution izo captured in terms of the information structures exchanged and the sequence and timing of these information exchanges among the resources. References 15754-1 specifications or standards that describe the types of resource interfaces used in performing the exchanges, the information structures, and the sequences of exchanges required for process coordination are captured in an information exchange interoperability profile.
In ISOa template for an information exchange interoperability profile, similar to Figure 5, is also defined. The interoperability of the two processes is determined by the interoperability of their respective resources and the associated information exchanges used to perform inter-process 157445-1. The combination of the set of interoperability profiles for all the resources and the set of interoperability profiles for all the isi exchanges needed to support the required flows of a particular manufacturing process is defined in ISO as a process interoperability profile.
The additional profiles for each process may include either additional interface types or configuration settings needed to support the complete set of cross-process flows. These resource and information exchange profiles can be distinguished by the 157455-1 of the enumerated interfaces, i.
When the IEC activity 15475-1 framework is extended 15745–1 Level F2, the processes associated with the crossapplication flows are modeled in terms of generic activities – move, make, test, and fixalong with a set of information structures and associated sequences of information exchanges, similar to Figure 2.
At Level F2, each integrated application will have a set of intra-process and inter-process interoperability profiles. The interoperability of all the processes within an application, determines the degree of integration within such application.
Following this scheme, the IEC operations management activities at Level 15754-1 are grouped into a set of processes which are further organized into a set of applications. By extending the ISO integration framework to model Level F3 applications, resource interoperability profiles are constructed for other types of resources, such as, mainframe computing units, local and wide area networks, manufacturing operations management personnel, and Level F3 software.
Similarly, each F3 application ixo an associated set of intra-process and inter-process ISO interoperability profiles that support cross-process flows among the F3 applications.
This set of process interoperability profiles is an extended form of an ISO application interoperability profile. In the steps leading to the construction of an application interoperability profile, several component integration models are generated, including those that show the roles of the resources, the directions of, sio of, and timings of the transfers of materials, energy, and information for both intra-process and inter-process flows.
The integration of applications within the F1 and F4 levels, are also denoted in terms of extended ISO interoperability profiles associated with activities and resources, at these levels, modeled using an extended IEC scheme.
In particular, a set of interprocess interoperability profiles represent the integration of Level F3 to Level F2 applications. Another set of profiles is used to denote integration of Level F2 to Level F1 applications.
The scope of the ISO application integration framework standard is concerned with manufacturing applications on the plant floor, situated at Levels F2 and below, within an application hierarchy. The scope of the IEC enterprise-control system integration scheme is concerned with the activities and the information structures at Level F3.
The Asset Health Assessment application interoperability In this paper, these two integration schemes are extended and combined to integrate applications either within a particular level or at different levels of an application hierarchy. By using harmonized UML-based integration models for the applications, processes, resources and activities at the various IEC levels within the functional and the resource hierarchies in an enterprise, one can use a common set of interoperability templates to describe the suite of profiles that enumerate the set of interfaces required to achieve interoperability and integration within a manufacturing application hierarchy.
Integration within and across levels within an application hierarchy At Level F1, a Condition Monitoring and Diagnostics application is composed of the following processes — Condition Monitor, Data Manipulation and Data Acquisition. For instance, the interfaces required to support the cross-process flows between a Health Assessment process of the Asset Health Assessment application and a Condition Monitor process of the Condition Monitoring and Diagnostics application are listed in their respective inter-process interoperability profiles.

W3C, Cambridge, Massachusetts, U. Each profile supports not only the interoperability of the processes within an application and but also their interoperability with the other processes in the other applications at various levels of the hierarchy.
In this scheme, the likelihood of interoperability of applications in an application hierarchy is ascertained by comparing their associated application interoperability is. Interoperability profiles expressed in XML can be compared in terms of their contents and structures. Applications with matching profiles indicate their consistent use of compatible interfaces types. Each resource interoperability profile in every process interoperability profile must be matched by a corresponding set of proposed resources intended to meet the requirements of an application hierarchy.
