Ontology for cloud manufacturing based Product Lifecycle Management

Abstract

The manufacturing environment has become increasingly competitive in the past few years, and product development is getting even more complex. The agility of an information system is a way to manage this complexity, and cloud technologies enable the sharing of tools and information in a new way. In particular, in the field of Product Lifecycle Management, a review of the literature demonstrates that there are technical issues that limit the efficient collaboration between the various stakeholders along the product lifecycle. Cloud manufacturing is a new concept that enables the virtualization of manufacturing resources and capabilities and provides them as a service. Therefore it offers new prospects for usage and collaboration in the extended enterprise, and along the product lifecycle. For instance, it helps to manage variations in production demand, by providing a large set of potential manufacturing resources on demand. However, to share the resources within the cloud manufacturing environment, a unification model of the domain information is required, to which any provider and/or user of cloud manufacturing must conform in order to dialog with the other CM stakeholders. This study provides an ontological model of the cloud manufacturing domain in order to support information exchange between the cloud manufacturing resources. The concepts of the proposed ontology are based on a literature review of models of cloud and models of manufacturing. The detailed ontology is then validated using the OntoClean methodology and within its implementation in an industrial scenario.

From data to big data in production research: the past and future trends

“…The adoption of cloud manufacturing can benefit the production processes in several aspects, including the ease of information exchange among multiple parties in the production process (Talhi et al 2017), sharing of manufacturing resources and smart distributed scheduling (He and Xu 2015;. From an economic aspect, cloud manufacturing also offers companies flexibility of scaling up and down their production costs because of the 'pay-as-you-go' business models (Xu 2012).…”

An Artificial Intelligent based System to Automate Decision Making in Assembly Solution Design

“…Thanks to all those cited potentialities, Ontologies are used in different domains, namely: the supply chain management [18 -20], the Product Lifecycle Management [20,21], the collaborative Product Development and Simultaneous engineering [22]. Actually, in the context of industrial product design phase, many works have been developed as examples:…”

Multi-Granularity Modeling and Aggregation of Design Resources in Cloud Manufacturing

“…Due to the powerful resource expression ability and the advantage in the aspect of semantic matching, ontology modeling technology [45] has become the mainstream method for resource modeling. According to the requirement of multi-granularity DR modeling, a kind of DR universal ontology modeling method is created, with which all kinds of resource ontology model are generated.…”
