Construction System

In Industry 4.0, a network of enterprises and factories is constructed collaboratively and dynamically according to the cyber physical system (CPS) paradigm. It is necessary to build smart supply chains according to this concept. A network of component enterprises in a supply chain would be modeled as a virtual supply chain in the cyber world. From the viewpoint of Industry 4.0, virtualizing a supply chain is the foundation for constructing a CPS for a supply chain. The virtualization of a supply chain makes it easier for companies to study their integrating and expanding opportunities. By using this CPS, comprehensive and autonomous optimization of the supply chain can be achieved. This virtual supply chain can be used to simulate the planning phase with negotiation, as well as the production phase. In this paper, instead of specific mathematical modeling for each supply chain, a general configuration method of a virtual supply chain is proposed. The configuration method of a supply chain model is proposed as a virtual supply chain using enterprise e-catalogues. A virtual supply chain is constructed as a multi-agent system, which is connections of software agents that are automatically created from each selected enterprise model in the e-catalogues. Three types of component enterprise models are provided: manufacturer model, part/material supplier model, and retailer model. Modeling templates for these three types of enterprises are prepared, and each template is a nominal model in terms of enterprise’s behavior. Specific component-enterprise models are prepared by filling the appropriate template. Each component enterprise agent is implemented using the enterprise model selected from the catalogues. Manufacturer, retailer, and supplier e-catalogues, as well as an automatic construction system of a virtual supply chain, are implemented. Methods for developing templates for the manufacturer, retailer and supplier were provided, and the construction system for specific enterprise models (as e-catalogues) is implemented as a trial.

Mortise And Tenon

Chinese ancient architectures are valuable culture heritages for human beings, and most of these ancient architectures are timber structures.[ Since most of the survived ancient architectures were built long time ago and suffered all kinds of nature disasters, their structures were damaged severely, and needed to be effectively reinforced and repaired. As the key element of Huizhou culture, Hui-style architecture is the representative of Chinese ancient architectures. Based on Hui-style architectures current damage situations, this paper studies the strengthen methods and current study situations of the timber structure of the ancient architectures from beam, column, mortise and tenon joint, corbel bracket, retaining structure and other aspects. It also studies the shortage of the traditional reinforcement methods, and discusses the usage of the new reinforcement material CFRP in the timber structure of the ancient architecture. In the end, the writer believes that finding sufficient methods to ensure the reinforcement effect, overcoming the shortage of the traditional reinforcement method, as well as ensuring the original appearance of the components when carry out the reinforcement, is the direction of the reinforcement study of Hui-style architecture in the future.

Walls of corridors and chambers in the Neolithic dolmens of Portugal and Spain were constructed using megalithic slabs or masonry. When constructed with slabs, the slabs were arranged using two very different construction systems, based either on placement of an orthostat or on imbrication of the slabs. Although generally dolmens are described with orthostats, on the Iberian Peninsula are most often constructed using imbricated slabs. The walls of orthostatic and masonry dolmens are lintelled structures. The walls of imbricated slab dolmens, however, are unique structures without later representation. Temporally, the orthostatic dolmens represent the earliest construction system, followed by those of imbricated slabs and finally those of masonry. This evolution can be explained in terms of the capacities of the selfsupporting walls and simplification of the construction processes.
