6. Manufacturing System Design
Many of the CIM design principles are formulated around the process function and information function aspects of the system (layers
2 and 4 of the multilayer model in Figs and 3-19). Guidelines are proposed for optimal functional relationships. The physical aspects of the process and control layers (layers I and 5) can then be viewed as real-world constraints that must be incorporated into the functional design.
Figure 3-20 illustrates a functional flowchart corresponding to layer 2 of the multilayer model. The manufacturing operations include
a computer-aided design (CAD) capability that is linked to a CIM cility. The facility consists of a variety of equipment units and'""'· ·· " that provide the necessary material transformation process.One of more or less obvious issues in facility design is to decide how various processing stations can be linked most effectively

7. Manufacturing Layer Design
Another, even more serial, approach to system design is indicated in Fig As indicated here, the design process begins with the func­ tional model of layer 2, constraints from layer l, and a set of specified inputs. The results of the layer 2 design are then fed into evaluations associated with layers 4 and 5, and a process of iteration results. The initial functional studies are simplified to emphasize the product flow and process functions within the manufacturing facility. All other as­ pects of the design are considered following this initial development. The advantage of this approach is the simplification that results. The disadvantage is that in producing this degree of serial development, a large number of iterations may have to be performed in order to begin to converge on an optimum solution.

9. Manufacturing Layer Design
This sequence of tasks leads to descriptions of alternative manufacturing system configurations that are appropriate for the combined product lines.
The products that are being considered are used as input to define the alternative manufacturing configurations.
In turn, the configuration descriptions depend on the manufacturing equipment that is available (or can be produced) and on the application of CIM design principles and reference models.
The next sequence of tasks leads to descriptions of alternative manufacturing system configurations that are appropriate for the com­ bined product lines. As shown in Fig.4-5b, the products that are being considered are used as input to defi ne the alternative manufacturing configurations. In turn, the configuration descriptions depend on the manufacturing equipment that is available (or can be produced) and on the application of CIM design principles and reference models. A num­ ber of computer modeling techniques can be applied to enhance the
description of these configurations.

10. Manufacturing Layer Design
The final activities require evaluation of the configurations and selection of the best system design, using a series of selection screens.
configuration must be evaluated in terms of the strategies to be used for product design and manufacturing and for the design-manufacturing interface.
A financial evaluation is then necessary to establish the costs associated with performance of each system alternative, while the or­ganizational evaluation is necessary to define the advantages and dis­ advantages that will be experienced in trying to achieve operations with each system alternative.
Finally, having passed through these screens, the evaluation process can be completed, and an implementation plan can be selected.

11. Manufacturing Layer Design
This sequence initiates the design, evaluation, and learning ac­tivities that must take place. Once these tasks have been completed.
It is necessary to start all over again and iterate through the cycle on a continuing basis.
Once an implementation plan is selected, the iteration can be used to learn from each stage of the experience.

12. Manufacturing Layer Design
The objective here is to apply the conceptual foundation devel­oped in earlier chapters to the creation of an operational approach for the planning and design of computer-integrated manufacturing systems.
The approach taken is to develop a step-by-step method that can guide the design process in general.
