|DELMIA Product and Resource Planning supports the complex task of manufacturing process planning in two methodically structured steps:|
- Determination of the process concept, which - based on the process graph - describes the processes as well as the process sequence and properties required for manufacturing the product.
- The outline and optimization of the manufacturing concept, which also describes in graphic form (symbol layout) the resources required for manufacturing the product, both qualitatively and quantitatively, and links them with the processes.
Within the process graph, the planner first determines the necessary (value added) manufacturing or installation steps and their required sequence for manufacturing the product. The processes are displayed as rectangles and their sequence by directional connecting arrows.
A series of processes can also be defined as a fixed, unalterable priority relation, which results for example from the geometry-oriented installation follow-up inspection and simulation with DPM for Assembly. The DELMIA PPR Hub is the integrating basis for all DELMIA products that specify or use the process (priority) graph.
The processes are linked to the elements of the product structure using the Drag & Drop function, which is shown in the DELMIA PPR Navigator. In this way, a variant code that may be available is transferred from the product node to the process. The linking of product and process is inherited in the subsequent actualization stages of planning (resources in the manufacturing concept or manufacturing layout).
Technical and classifying attributes are available for describing the process properties and can be completed and adapted in any way you like within the framework of the configuration. Execution times can be stored both as an estimated value and as an analyzed value of the processes. Here you can gain access to the standardized analysis procedures used worldwide and to the time components which they define (company-specific process standards) using the integrated DELMIA Standard Time Measurement.
Proven processes and procedural results can also be saved as reusable templates and are available from the library to be used in all planning procedures as a modifiable template or fixed standard.
While the process concept provides answers about the processes as well as the process sequence and properties required for manufacturing the product, the manufacturing concept answers the question as to which resources machinery, tools, logistic aids and the human work force are used to realize the processes in the factory. Non-value-added activities are also typically recorded here as part of the planning - such as transport and testing procedures which are unavoidable for the successful execution and perpetuation of production and which incur costs.
The manufacturing concept graph can be automatically derived from the process graph as an initial outline. This results in a 1:1 allocation of processes and resources (work stations), which can be quickly and easily changed using a variety of convenient editing functions. You can use this method, for example, to plan new product-specific manufacturing plants scheduled for construction.
The resources of an existing manufacturing concept graph can also be linked individually to any of the various processes available in the PPR structure. This can be done directly using the Drag & Drop function. According to this principle, the manufacture of new products is planned using existing plants (typically workshop manufacturing ).
The resources are represented in the manufacturing concept graph by type-specific symbols, which can be freely configured according to type, quantity and shape. Different colored connecting lines or directional arrows are used to represent links (such as worker to machine) and material flow.
All of the important information such as process and performance times, information for media use and all directly calculable preparation and operating costs can be stored in the resources.
The analysis functions assigned to the manufacturing concept show the current level of utilization of resources at all times according to the planning state, the amount of human labor and the total costs being incurred for the preparation and operation of the future manufacturing process. In this way, the planner can continuously monitor the costs of product manufacturing over which he has some control. Based on this analysis, he can compare alternative manufacturing concepts with regard to economic indicators.
The analysis is based on a number of so-called premises. They consist of boundaries and standards, which include time-related planned quantities for product and manufacturing, target costs, working time or shift model and technical requirements of the manufacturing location.
If the DELMIA Layout Planning product is available, a three-dimensional preliminary layout outline can be generated from the manufacturing concept graph, which can later be further edited interactively. When generating the layout, specific components from the system elements library or form-describing macros should already have been assigned to the resource symbols in the manufacturing concept graph. Each resource symbol can even be linked to a 3D macro from the very start. (Feasible within the scope of the system configuration.)
In a similar way, if DELMIA Quest is available (with PPR hub integration), the manufacturing concept graph can be transferred into a Quest model capable of simulation. Thus, the layout of resources, which up until this point was only static (machines, transport and buffer capacity), can also be dynamically checked, analyzed and optimized that is, including the effects of any faults that may have occurred.
Both the process and manufacturing concepts can be structured for better manageability. This can be accomplished either by sub-dividing into groups or by creating a hierarchical structure of subordinate graphs.
DELMIA Process and Resource Planning stores all data in the DELMIA PPR hub. In this way, the created information is also visible and can be queried in the PPR Navigator under the specific process or resource node . And vice versa, the processes and resources created in the Navigator are also displayed in the process graph or in the manufacturing concept graph and can be inserted into the process at that point by the planner.
