The quick consuming of products and the strong competition
between producers caused to increase the complexity of products, so
the digital factory became a need between design and producing
actually to achieve a production system with a shorter ti
me and
optimal design and parameters without engineering modifications.
This research offering a reference model basing on a complete
framework between the engineering applications to build a
computational model with a single core based on the integration
between three dimensions modeling and automation of application
for digital factory concept, to optimize the design of achieving the
ideal execution of actual production system. Where we achieved the
control of three-dimensional computer model according to process
automation exactly as in actual through integrating tools, where the
percentage of exact between the real factory and digital factory was
83% by using the time of process as the main factor for comparison
in this evaluation.
