Independent Cycle Time Assignment for Min-max Systems

引用

International Journal of Automation and computing 2010年第2期7卷 254-260页

作者： Wen-De Chen Yue-Gang Tao hong-nian Yu Academy of Mathematics and Systems Science Chinese Academy of Sciences Beijing 100190 PRC Department of Mathematics Zhengzhou University Henan 450001 PRC Institute of Automation Chinese Academy of Sciences Beijing 100190 PRC Faculty of Computing Engineering and Technology Staffordshire University Stafford ST16 9DG UK

A variety of problems in digital circuits, computer networks, automated manufacturing plants, etc., can be modeled as min-max systems. The cycle time is an important performance metric of such systems. In this paper, we focus on the cycle time assignment of minimax systems which corresponds to the pole assignment problem in traditional linear control systems. For the min- max system with max-plus inputs and outputs, we show that the cycle time can be assigned disjointedly by a state feedback, if and only if the system is reachable. Furthermore, a necessary and sufficient condition for the cycle time to be assigned independently by a state feedback is given. The methods are constructive, and some numerical examples are given to illustrate how the methods work in practice.

An Efficient Frontier for Sum Deviation JIT Sequencing Problem in Mixed-model Systems via Apportionment

引用

International Journal of Automation and computing 2012年第1期9卷 87-97页

作者： Tanka Nath Dhamala Gyan Bahadur Thapa hong-nian Yu Central Department of Mathematics Institute of Science and Technology Tribhuvan University Nepal Department of Mathematics Pulchowk Campus Institute of Engineering Tribhuvan University Nepal Faculty of Computing Engineering and Technology Staffordshire University Stafford UK

In this paper, the sum deviation just-in-time （JIT） sequencing problem in mixed-model production systems is studied relating with the discrete apportionment problem together with their respective mathematical formulations. The assignment formulation for the first problem is briefly discussed followed by the existence of JIT cyclic sequences. Presenting the concise discussion on divisor methods for the discrete apportionment problem, we have proposed two mean-based divisor functions for this problem claiming that they are better than the existing divisors; hence, we found a better bound for the JIT sequencing problem. The linkage of both the problems is characterized in terms of similar type of objective functions. The problems are shown equivalent via suitable transformations and similar properties. The joint approaches for the two problems are discussed in terms of global and local deviations proposing equitably efficient solution.

A Comparison of Mamdani and Sugeno Fuzzy Based Packet Scheduler for MANET with a Realistic Wireless Propagation Model

引用

International Journal of Automation and computing 2015年第1期12卷 1-13页

作者： Oche Alexander Egaji Alison Griffiths Mohammad S.Hasan hong-nian Yu Faculty of Computing Engineering and Sciences Staffordshire University Faculty of Science and Technology Bournemouth UniversityFern Barrow Pool Dorset UK

The mobile nature of the nodes in a wireless mobile ad-hoc network(MANET) and the error prone link connectivity between nodes pose many challenges. These include frequent route changes, high packet loss, etc. Such problems increase the end-toend delay and decrease the throughput. This paper proposes two adaptive priority packet scheduling algorithms for MANET based on Mamdani and Sugeno fuzzy inference system. The fuzzy systems consist of three input variables: data rate, signal-to-noise ratio(SNR) and queue size. The fuzzy decision system has been optimised to improve its efficiency. Both fuzzy systems were verified using the Matlab fuzzy toolbox and the performance of both algorithms were evaluated using the riverbed modeler(formally known as OPNET modeler). The results were compared to an existing fuzzy scheduler under various network loads, for constant-bit-rate(CBR) and variable-bit-rate(VBR) traffic. The measuring metrics which form the basis for performance evaluation are end-to-end delay, throughput and packet delivery ratio. The proposed Mamdani and Sugeno scheduler perform better than the existing scheduler for CBR traffic. The end-to-end delay for Mamdani and Sugeno scheduler was reduced by an average of 52 % and 54 %, *** performance of the throughput and packet delivery ratio for CBR traffic are very similar to the existing scheduler because of the characteristic of the traffic. The network was also at full capacity. The proposed schedulers also showed a better performance for VBR traffic. The end-to-end delay was reduced by an average of 38 % and 52 %, respectively. Both the throughput and packet delivery ratio(PDR) increased by an average of 53 % and 47 %, respectively. The Mamdani scheduler is more computationally complex than the Sugeno scheduler, even though they both showed similar network performance. Thus, the Sugeno scheduler is more suitable for real-time applications.

Ar-Ar Dating of Baimazhai Nickel-Copper-(PGE) Sulphide Deposit and Its Significance, Southeast Yunnan Province, China

引用

Journal of China University of Mining and Technology 2006年第2期16卷 200-205页

作者： ZHANG Xue-shu QIN De-xian Franco Pirajno nian hong Department of Geological Science Kunming University of Science and Technology Kunming Yunnan 650093 China Yunnan Non-ferrous Metals Geological Bureau Kunming Yunnan 650051 China Geological Survey of Western Australia 100 Plain Street WA 6004 Australia

The Baimazhai Ni-Cu- (PGE) sulphide deposit in southeast Yunnan Province is hosted in mafic-ultramafic intrusions associated with the Permian Emeishan large igneous province. The deposit, one of several in the province, exhibits field and petrographic features suggestive of post-magmatic modification. The mafic-ultramafic intrusions that host the Baimazhai sulphide ores show near-pervasive to pervasive hydrothermal alteration, with the sulphides be- ing spatially associated with hydrothermal minerals such as biotite, amphibole and chlorite. This intimate association suggests that the sulphide ores were subjected to deformational and hydrothermal redistribution and textural changes resulting in disseminated and brecciated ores. Geochemically the Baimazhai sulphide ores are enriched in Cu, Pd and Au which, according to published studies, reflects the action of hydrothermal fluids. Interestingly, Ar-Ar age data yielded plateau ages of about 160-170 Ma, which also supports the modification features of the sulfide ores.

International Journal of Automation and computing 2019年第1期16卷 52-64页

作者： Shang-Lian Peng Ci-Jian Liu Jia He hong-nian Yu Fan Li College of Computer Science and Technology Chengdu University of Information Technology The Southwest Jiaotong University(SWJTU)-Leeds Joint School Southwest Jiaotong University School of Computer Science and Network Security Dongguan University of Technology Faculty of Science and Technology Bournemouth University

Radio frequency identification(RFID) enabled retail store management needs workflow optimization to facilitate real-time decision making. In this paper, complex event processing(CEP) based RFID-enabled retail store management is studied, particularly focusing on automated shelf replenishment decisions. We define different types of event queries to describe retailer store workflow action over the RFID data streams on multiple tagging levels(e.g., item level and container level). Non-deterministic finite automata(NFA)based evaluation models are used to detect event patterns. To manage pattern match results in the process of event detection, optimization algorithm is applied in the event model to share event detection results. A simulated RFID-enabled retail store is used to verify the effectiveness of the method, experiment results show that the algorithm is effective and could optimize retail store management workflow.
