An Efficient IT Energy-Saving Approach Based on Cloud Computing for Networked Green Manufacturing

Networked manufacturing technology has provided an effective approach to integrating manufacturing resources over Internet. However, a vast number of resources involving networks, computing, and storage resulted in ever increasing energy consumption. This paper proposed an IT energy-saving approach based on Cloud Computing for networked green manufacturing.

Then the paper discussed the dynamically-scalable resource utilization mechanism for networked manufacturing. The approach can provide effective support for manufacturing resource virtualization and deliver a variety of services to distributed manufacturing enterprises. Moreover, IT resources of network, computing, and storage can be shared concurrently and scheduled dynamically that are adaptive to practical resource demand of collaborative manufacturing tasks. Thus, a great amount of IT resources can achieve high efficient utilization in networked manufacturing and result in reduced energy consumption to benefit green manufacturing.

Research on the Measurement Method of Flexibility of Resource Service Composition in Cloud Manufacturing

In order to overcome the bottlenecks of traditional network manufacturing, a new service-oriented networked manufacturing model, i.e. the cloud manufacturing (CMfg), was proposed recently. As an effective method for the realization of the added value of manufacturing resource, resource service composition (RSC) plays an important role in the implementation of CMfg. In view of the issue of dynamic changes occurred during RSC in CMfg, this paper presents the concept of flexibility of RSC as well as the idea of optimal-selection of RSC based on flexibility, which can enable RSC to have the ability to adapt to the dynamic changes. Meantime, the measurement method of flexibility of RSC is investigated. The optimal-selection of RSC based on flexibility can be achieved through quantitative evaluation of flexibility.

Research on Compression Methods for ASCII STL File

Two new types of ASCII format STL file are presented under lossless data compression and lossy implicit data compression respectively. In these new format file, a vertex with three coordinates which has degree n is stored only once rather than n times and three vertexes of a facet are saved by their indexes instead of by their three coordinates (x, y, z). As a result, the storage space of the vertex reduces to about 1/3 of its original space. It is very convenience for the file transmitting of network manufacturing. Moreover, the reading, writing and pretreatment time of data file are shortened greatly because of the decreasing of the file length.

Setting manufacturing strategy for a company's international manufacturing network

Manufacturing strategy is a plan for moving a company from where it is to where it wants to be. Determining the best manufacturing strategy is not easy because of the wide range of choices and constraints a company faces. Manufacturing strategy frameworks or models are helpful because they identify the objects that comprise manufacturing strategy and organise these objects into a structure that enables a company to understand and use the objects to develop strategy. This paper examines a company's international manufacturing network. It identifies and examines six manufacturing strategy objects (generic international strategies, manufacturing networks, network manufacturing outputs, network levers, network capability, and factory types), linkages between objects, and the manufacturing strategy framework that follows from these objects and linkages. Then the paper applies the framework to the manufacturing networks of three companies in the global steel industry: Arcelor (Luxembourg), Mittal (India), and Dofasco (Canada).

Collaborative Manufacturing Unit Selection Using a Sorting Adaptive Genetic Algorithm in Networked Environment

In order to solve the collaborative manufacturing unit (CMU) selection problem in the networked cooperative manufacturing environment, a sorting adaptive genetic algorithm is proposed. To obtain the optimal executive manufacturing process, the objective function is constructed considering manufacturing cost and product load rate of candidate CMUs under time-sequence constraint. The embedded subtask scheduling procedure in sorting adaptive genetic algorithm is used to ascertain the penalty cost for the tardiness of the task. Finally, a case study is implemented to verify the feasibility of the proposed approach. The results show that the proposed model and algorithm can obtain satisfactory solutions.
