In order to solve the problem of information islands in the process of hull block manufacture, which affecting the information transfer between different department and work unit, An integrated model of BOM multi-view is used. Based on the whole process of hull block manufacture, the transformation rules are summed up 2 categories and a total of 12 types in the integrated model of BOM multi-view....
RoHS2 takes effect in EU Member States from 2 January 2013 and is a CE Marking Directive. RoHS2 requires Manufacturers to follow the procedures in Module A of Decision 768/2008/EC which prescribe the conformity assessment procedures that Manufacturers must carry out and the technical documentation they must draw up to demonstrate that their products are RoHS compliant. Many companies already have...
In view of the dynamic changes in a supply chain network and the significance of order fulfillment processes (OFPs) for the successful implementation of supply chain management, this paper puts forward an accountability-based methodology for companies to reengineer OFPs while considering both external and internal changes. In the methodology the accountability centered approach and the simulation...
The paper attempts to present the big picture of lean consisting of thought process behind lean rather than just a smaller view concentrated on lean tools only. Importance of five elements of lean is discussed to appreciate the synergetic effect of each element on others, towards making an organization lean. Further, a case study on lean manufacturing implementation experience of an Indian manufacturing...
Topology and weights are closely related in weighted complex networks and this is reflected in their modular structure. We present a complex parts network model based on weighted complex network theory that the nodes are parts of the product, the edges are engineering change transfer relations of the parts, the node weights express the complexity of the parts and the edge weights express the connection...
The competitiveness of an enterprise depends not only on its internal performance to produce products and services but also on its ability to seamlessly interoperate with other enterprises. External and internal collaborative work needs more interoperable solutions. How to enhance interoperability between stakeholders and improve efficiency of supply chain management is the key issue that needs to...
Work on the construction site is known to be inefficient due to workers spending much time waiting for materials, transporting materials and from frequent interruptions of tasks. Studies on the construction site typically use statistical measures to analyse the sampled data about work and such measures, while very useful, can overlook important features of the data. In this paper we apply a previously...
The construction industry has been facing a paradigm shift to (i) increase; productivity, efficiency, infrastructure value, quality and sustainability, (ii) reduce; lifecycle costs, lead times and duplications, via effective collaboration and communication of stakeholders in construction projects. Digital construction is a political initiative to address low productivity in the sector. This seeks...
In order to realization electronic parts product appearance quality detection control, one kind of processor based on the intelligent knowledge automatic extraction and system intelligence modeling was presented. In the processor, wavelet-fuzzy technique and neural network technique are combined. Uses the fuzzy wavelet extraction image feature, and wavelet function is used as fuzzy membership function...
Optical communication systems based on dense wavelength division multiplexing (DWDM) would benefit from the ability to adjust the operating wavelength of a laser transmitter. Previous attempts, including thermal adjustment, etalon based wavelength locking, and various types of optical frequency and phase locked loops such as the Pound-Drever-Hall technique suffer from weaknesses including sensitivity...
