Cloud computing is changing the way industries and enterprises run their businesses. Cloud manufacturing is emerging as an approach to transform the traditional manufacturing business model, while helping the manufacturer to align production efficiency with its business strategy, and creating intelligent factory networks that enable collaboration across the whole enterprise. Many production planning and control problems are essentially optimization problems, where the objective is to develop a plan that meets the demand at minimum cost or maximum profit. Because the underlying optimization problem will vary in the different business and operation phases, it is important to think about optimization in a dynamic mechanism and in a number of interlinked sub-problems at the same time.Cloud manufacturing has the potential to offer decision support as a service and medium of communication in production planning and control. To solve these problems and produce collaboration across the supply chain, this paper provides an overview of the state of the art in cloud manufacturing and presents a model of cloud-based production planning and production system for sheet metal processing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
