Each enterprise is consist of different factories and every factory is comprised of shops also shops include cells. In each of these levels there are different Information systems modeling Approaches:•cell : O-O, Entity relation ship , functional modeling•Shop: Multi agent system or holonic manufacturing system•Factory: capability modeling•Enterprise: competency modeling

CapabilityCapability, is defined as the ability to execute a specified course of action.Capabilities refer to the corporation’s ability to exploit its resources. On the other view consist of activity and knowledge of resource. They consist of a series of business processes and routines that manage the interaction among its resources. For example, a company’ s marketing capability can be based, among other things, on the interaction among its manpower (marketing specialists), technology (computer hardware and software) and financial resources.

Competency

Competency is the information of resources and corresponding activities as well as the knowledge about how these resources and activities could be effectively, efficiently and economically used.A competency is a cross-functional integration and coordination of capabilities. In a multi-business corporation, competencies are a set of skills and know-hows housed in an enterprise. They result from interfaces and integration among the enterprise’s functional capabilities. For example, a particular enterprise may possess the competency of developing successful new products. Such a competency may be the consequence of integrating marketing capabilities, R&D capabilities and production capabilities.

The hierarchy system

Core competencies is the highest level in the hierarchy. They result from the interaction between different competencies. A core competency is a collection of competencies that are widespread in the corporation. Core competencies are skills and areas of knowledge that are shared across business units and result from the integration and harmonization of enterprises. Detailed modeling of the enterprise’s resources, capabilities and competencies will result in a better understanding of the enterprise. Such in depth understanding can lead to a better match between external opportunities and internal strengths because once the corporation knows its areas of strength, it can search the external environment to identify possible ways of better exploiting those strengths.

Based on the figure proposed by javidan(1995), the distinction between competency and capability is that capability is not multi disciplinary so we use capability in the factory level like manufacturing capability , design capability and so on, but at the enterprise level which is a multi disciplinary area we use competency .

Product model• Ever increasing global competition requires that products be produced more quickly, more

economically, and with more custom tailoring according to the customers’ wishes. Companies operating in a heavily networked business environment must be able to make product changes and find required information quickly.

• The product information (data) model is a concept model that analyses information on the product and its relationship with other pieces of information by describing them formally and carefully. A product model – a general product structure for a certain individual product –contains information on an individual product, recorded and arranged according to the product information (data) model. The product model contains all the product-related information during its life cycle.

• The changed physical properties or subsections of the product are called variants. Only a generic structure, containing the possible variants, is created during the product development process. Individual products are formed only during the order-delivery process, when the actual physical products are created and manufactured, and delivered to customers.

• Several commercial applications are available for the management of product data or product information and for the system development and system integration of data transfer extensions within and between organizations. They are based on the methods of numerous standards such as XML (Extended Markup Language) or STEP.

STEP, Standard for the Exchange of Product Model Data

• STEP is an international standard, based on the idea of product models, for representing standard product data. The central idea of STEP is to make the transfer of product data possible between various departments within companies, and between separate companies, organizations, and separate users, with different software applications, over the whole life cycle of the product. With STEP, the data transfer takes place through a standard-type neutral -in other words commercially independent- product model, and standardized file formats, programming interfaces and application protocols.

• The objective of the standard is to make possible the connection, into a functional totality, of:

– Computer aided design (CAD – Computer Aided Design) �– Computer aided work and task design (CAPP – Computer Aided Process Planning) �– Computer aided manufacturing (CAM – Computer Aided Manufacturing)�

• In other words, the aim is to provide companies with the preconditions for actual integrated production (CIM – Computer Integrated Manufacturing).

Capability Models for a Factory

Using the proposed capability model different capability models can be demonstrated. e.g. manufacturing capability model

Manufacturing Capability ModelThe manufacturing model is an information model that describes the manufacturing capability of an enterprise.

A manufacturing data model (MDM) defines the data structure that should be able tosupport the construction of a manufacturing model, which can consistently represent themanufacturing capability information of a facility.

A manufacturing capability model (MCM) is an information model which defines the dataflow structure, that can consistently represent the manufacturing capability information of a facility.
