This paper proposes a distributed manufacturing scheduling framework at the shop floor level. The shop floor is modeled as a collection of multiple workcells, each of which is modeled as a flexible manufacturing system. The framework consists of a distributed shop floor control structure, dynamic distributed scheduling algorithms, multi-agent system modeling of workcell, and service oriented in...

Very large database systems require distributed storage for expansibility and high throughput, which means that they need distributed search structures for fast and eecient access to the data. In a highly parallel distributed search structure, parts of the index must be replicated to avoid serialization bottlenecks. Designing distributed and replicated search structures is made diicult by the c...

Wireless Sensor Networks (WSNs) consist of many wireless sensor nodes for collecting and sensing information. Distributed Ledger Technologies (DLTs) such as Blockchain allow organizations to store share data in a decentralized, immutable, secure way through network distributed peer-to-peer users or computers. The application DLT the Internet Things (IoT) can improve efficiency information trans...

the aim of this study is to analyze the impact of industrial structure of clusters on entrepreneurship in business clusters (case study: valuable metals and precious stones of isfahan's clusters). the relevant population is isfahan clusters of valuable metals and precious stones. number of population is over than 300enterprises. according to the formula of sampling structural equation mode...

the alien polychaetes are widely distributed in the whole mediterranean sea as well as in theegyptian waters. the objective of this study is to highlight the distribution and abundance of the alienpolychaetes along the alexandria coast, their contribution to the total polychaete community and the changesthey caused in the community structure. through monthly sampling polychaetes were collected ...
