- A system paradigm is an abstract representation of the system; it is thesystem architecture that determines the types and numbers of the components andtheir relations in operation and interaction of the system. Its selection relies oncustomers’ requirements and manufacturing environment. Many system paradigmshave been proposed. However, most of them are based on an assumption that thelife-cycle and boundary of a system can be defined based on the customers’requirements. Since sustainability becomes essential to today’s manufacturingsystems, a new concern is how to evolve existing paradigms to meet new chal-lenges. The objectives of this chapter are, therefore, to examine the manufacturingrequirements in a wider scope, to revisit existing paradigms to clarify the limi-tations and bottlenecks, and eventually to identify future research directionstowards sustainable manufacturing. Within the context, this chapter focuses moreon Reconfigurable and Cloud manufacturing system paradigms, and highlights thefuture endeavors towards better sustainability.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- The successful design and application of a large and complex manufacturing system relies not only on the maturity of its fundamental design, but also on the technologies for seamless integration and coordination of system components, since a large manufacturing or logistic system often adopts a decentralised control architecture to manage its complexity. System components are usually distributed; their behaviours are enacted locally and autonomously. The control objective at the system-level is achieved by the executions of the sub-objectives at the component level, subjected to the condition that the controls of the sub-systems have to be coordinated via effective communication. In developing algorithms for communication and coordination of a networked distributed system, algorithm verification is complicated and trivial, due to the invisible information system. In this chapter, we propose to use the conventional simulation tool, Deneb/QUEST, for modelling and visualisation of the coordinating behaviours. Its vivid graphical environment can be a great assistance in accelerating software debugging and verification and in reducing the time for software development. General architecture of a networked distribute system is introduced, the system components are analysed, and the correspondences between these components and QUEST elements are established. A case study for the verification of ring extrema determination (RED) algorithm is used as an example to illustrate the general procedure and the feasibility of the proposed approach.

- Eutectic high-entropy alloys (EHEAs), as a subclass of high-entropy alloys (HEAs), exhibit various excellent mechanical, physical, and anti-corrosion properties as well as excellent castability, which are becoming one of the research frontiers in the metal alloy field. EHEAs combine nicely the unique advantages of eutectic alloys and HEAs, with in-situ formed composite structure containing multi-principal components during the solidification process. Since the first report of EHEAs in 2014, plenty of investigations have been made on the topic, resulting in dozens of promising candidate EHEAs for future applications. In this chapter, the recent research advances in EHEAs were summarized, to comprehensively present the historical development, current situation, and future aspects of EHEAs. The concept of EHEAs was firstly introduced, which was proposed based on the special solidification microstructure of eutectic alloys. The excellent mechanical performance in directly cast EHEAs inspired rapid developments on this topic. Then, several alloy design methods were introduced, for the efficient prediction of new EHEA systems. Meanwhile, the deformation behavior and mechanisms have been thoroughly investigated for a mechanistic understanding of the superior mechanical properties of EHEAs, and they were summarized here. Finally, the potential applications and future developments of EHEAs were suggested as a concluding remark.

Simulation of urban rail operations : Models and calibration methodology

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- SimMETRO is a microscopic, dynamic, stochastic simulator of urban rail operations (METRO), specifically designed for service performance analysis, and the evaluation of operations and strategies for a real-time control of subway systems. SimMETRO employs a detailed representation of the network, rolling stock, signal control, demand, schedule and dispatching. In particular, the various sources of stochasticity in operations are explicitly captured. This chapter presents approaches for the calibration of model parameters and input (such as dynamic arrival and alighting rates), and a case study illustrates the applicability of the model and the proposed calibration methodology. After calibration, the RMSE of block run times (relative to actual times as reported by the train detection system) was reduced by 60% as compared to the default values. The calibrated demand was in good agreement with recent counts of arrival rates at the stations.
