20、Annex B (informative) Economic View in CIM system architecture B.l General B.l.l Introduction For entrepreneurs and business managers, confidence in advanced CI M technology depends upon the realization of a return on investment projected from design phase activities of both new system implementatio

21、ns and system up-grades and re-organizationshtegrations. Since both tangible and intangible benefits must be considered, evaluating the return is a difficult problem. An essential aspect of any mechanism to resolve the problem is the ability to evaluate different alternatives using models of existin

22、g and proposed system architectures in a manner that connects functionality with economic consequence so that design trade-off decisions are possible. In particular, the evaluation of intangible benefits is often a barrier to Computer Integrated Manufacturing investments. An Economic View presents m

23、odel content relative to economic decisions. It draws upon existing model content and established analytical methods to inform decision makers. The view is most critical early in the life cycle when the majority of economic commitments are encountered and late in the life cycle when economic perform

24、ance is measured. B.1.2 Support for enterprise managers As guidance for enterprise managers, the Economic View can help them to: a) predict the influences of system integration on the enterprise, b) evaluate necessary investment and possible benefits, c) make decisions and improve their correctness,

25、 and d) monitor the implementation process and application of the integrated system. B.1.3 Support for enterprise model developers and analyzers As guidance for model developers and analyzers, the Economic View helps them to: a) describe the economic elements, b) understand relationships between the

26、se elements and other components in an integrated system, c) describe economic relationships among enterprise strategic targets, the framework of the integrated system and its components, and d) identify economic benefits of enterprise re-organization. 2 O IS0 2005 - All rights reserved IS0 15704:20

27、00/Amd.l:2005(E) B.1.4 Support for system developers As guidance for the system developers, the Economic View provides: a) methods to evaluate economic consequences of system function modifications during the system development, and b) scoping of software tool use for economic modeling and analysis.

28、 B.2 Framework for Economic View In system implementation/integration projects, the goals and corresponding demands of the project target are reflected in the demands of the economic characteristics. Their economic implications/influences on the system are realized through the integration strategy a

29、nd the technology project. The Economic View establishes the relations between the economic target and the engineering project. It describes economic elements, influence factors and scalar indices manifested in the integrated system and their relationships that allow the determination of their impac

30、ts on the economic targets in the system integration project. These indices, factors, and elements are constructs and their properties taken from or derived from the four mandatory model-content views (4.2.1 O) In an integrated system, the Economic View consists of a grouping of models, which is use

31、d to describe economic components and their relationships. Many methods, e.g., graphical, mathematical, and even descriptive ones, may describe economic components. In order to improve the compatibility and assure the successful operation of an enterprise, a three-layer framework is constructed, exp

32、ressed in graphic form, based on enterprise modeling methods and reference models in the general enterprise reference architecture, as shown in Figure BI. The three layers in the Framework for Economic View (Indices, Factors, Elements) possess different economic attributes and the relationships amon

33、g layers have different attributes as well. The framework establishes the relationships between layers of detail from the top level strategic targets of an enterprise to the bottom basic economic elements with intervening indices and factors. To correctly establish the relationships among different

34、layers, both clustering and classification methods should be used to gather information from the generic and partial model pool for the applicable life cycle phases and then classify the information to establish the particular trees and relationships. Early in the life-cycle, economic targets (ET) a

35、nd constraints are established, e.g., return on investment, and pricing levels. Relative to this domain identification and concept definition, sets of economic indices (I,) bearing on the targets and constraints are arranged and analytic methods are chosen with increasing levels of detail exposed as

36、 the life cycle progresses. At the factors layer, process related cost factors are derived from the decomposition of process models into activities (fp). At this layer other economic factors result from the analytical breakdown of expected value that can be both tangible and intangible (fA). All of

37、the indices have both tangible and intangible factors. Even the most tangible indices, cost (ic) and time (IT) may have intangible factor influences that need to be taken into consideration. The explicit intangible factors, service (Is) and environment (IE) may have tangible factors as well, e.g., r

38、esponse time, pollution rate, etc. Tangible factors have diverse forms and representation. They can be expressed in mathematical equations (fE), matrices, tables (fT), boxes in graphical models, etc. In Figure B.1, the design phase is shown with greater elaboration using a tree of decomposed indices

39、, process factors (fp) depicted as a process model fragment, analytical factors (fA) depicted as hierarchy models, equation factors (fE) depicted as a formula, and table factors (fT) depicted as a data table. For factors, the element layer identifies the basic economic elements that comprise the var

40、iables in the mathematical equations (eE), the entries in the matrices and tables (eT), the activities (such as an activity box, e.g., in the lowest level IDEF3 model, (eA), etc., from which the factor cost or value are derived. These elements are usually simple attribute values characterized as ind

41、ivisible, and can be used to measure, monitor, or control the related factors. In general the elements are properties of resources used to value and cost an activity. Economic indices, factors, and elements can be of generic types collected as a pool of constructs for use at the various layers. Thes

42、e generic types can be formed into partial models of indices and factors to be used as an aide for populating a particular economic view through specialization. O IS0 2005 -All rights reserved 3 IS0 15704:2000/Amd.l:2005(E) Analysis methods vary by layer with, for example, tree hierarchy analysis te

43、chniques appropriate at the Indices layer, and process structure model simulation, hierarchy analysis, physics formulas, fit and interpolation methods at the Factor layer. These analysis methods collect data and support the decision optimization of the enterprise. Optimization results can be imposed

44、 on attributes to realize the enterprise strategy and improve its competitive ability. Two iterations of optimization and control exist - the target decomposition from the top down at Requirements, followed by system analysis from the bottom up at Design occurs early in the life cycle and then the s

45、ystem implementation from the top down at Implementation and the system monitor and control from the bottom up at Operation occurs later in the life cycle. The first iteration results in the roll-up of economic valuations for comparison against the targets and constraints. The second iteration provi

46、des measures of economic performance. Such methods can assure the realization of the enterprise target, the fundamental information collection and analysis, the rationalized target fulfillment and the system monitoring. Implementation of the framework should be supported by correct methodology, rich

47、 engineering practices and advanced theories and methods of system integration. Initiatives in concurrent engineering, cell technologies, and total quality management may be coupled with capital and labor investment for economic benefit. The analysis and evaluation of different implementation altern

48、atives of CIMS can be performed using the Economic View. The selection of the best alternative from many opportunities to implement system integration and the improvement of the enterprise competency is achieved as a result of specific modeling methods.
