Mature landfill leachate, containing high concentration of nitrogen, and low ratio of C/N, is difficult for biological treatment .In this paper, the leachate treatment of Jiangmen Landfill Site was studied. There is new requirement of the Standard for Pollution control on the Landfill Site (GB16889-2008) of effluent TN concentration, after the processes of "SBR-Fenton-BAF". Two-stage BAF was carried out in the pilot plant study to improve the old treatment processes. The influent of this pilot was the effluent of Fenton process with TN concentration was 120∼200 mg • L-1. The efficiency of various carbon source for nitrogen removal was of the following order: methanol> glucose>sucrose .By the conditions of influent added with methanol as external carbon source and HRT was 7h, TN concentration of the effluent was less than 40 mg • L-1, reach to the new discharge standards after treatment. © 2011 IEEE.

Dynamic job rescheduling using RFID technology

International Journal of Internet Manufacturing and Services 2011年第1期3卷 42-58页

Dynamic job shop scheduling/rescheduling is a frequently occurring and highly relevant problem in practice. However, in the past, due to being short of the real-time manufacturing information derived from the bottom-level manufacturing spots, the scheduling solutions produced by the traditional job shop scheduling systems are always unable to satisfy the practical requirements well. Therefore, in this research, a dynamic job rescheduling approach is proposed in which radio frequency identification (RFID) technology is utilised to acquire the real-time manufacturing information produced at the manufacturing spots and a dynamic rescheduling mathematical model is established to deal with the four types of uncertain events frequently occurring in job shop production. Endeavouring to resolve the dynamic scheduling mathematical model effectively and efficiently, a hybrid genetic algorithm (GA) by integrating hill-climbing search method is introduced. A prototype system of RFID-based dynamic job rescheduling is developed and the numerical case studies are carried out for verifying the feasibility and validity.© 2011 Inderscience Enterprises Ltd.

A Single-Item Uncapacitated Lot-Sizing Problem with Remanufacturing and Outsourcing

Procedia engineering 2011年 15卷 5170-5178页

This paper addresses the single-item, dynamic lot-sizing problem for systems with remanufacturing and outsourcing. Therein, demand and return amounts are deterministic over a finite planning horizon. Demand may be satisfied by the manufacturing of new items, remanufactured items, or outsourcing, but it cannot be backlogged. The objective of this study is to determine the lot sizes for manufacturing, remanufacturing, and outsourcing that minimise the total cost, which consists of the holding costs for returns and manufactured/remanufactured products, setup costs, and outsourcing costs. The problems addressed in this paper are an extension of those addressed by Richter et al. (2000,and 2001), Teunter et al. (2006), and Aksen et al. (2003). In this paper, the separate setup costs scheme is considered, we propose a dynamic programming approach to derive the optimal solution in the case of large quantities of returned product. The complexity of this dynamic programming approach is O ( T 2 ), wherein T is the number of periods in the planning horizon.

In this paper, we examine the knowledge transfer process on community networks by analyzing the average knowledge level as a function of the agent's absorptive capacity. It is found that the average knowledge level decreases with the increment of inner-community links and the decreases of intercommunity links when we keep the total links (including innercommunity and inter-community links) constant. It is also shown that as for inner-community (inter-community) links unvaried, the increment of inter-community (inner-community) will promote average knowledge level. © 2010 IEEE.

In this work, scheduling problems with resource allocation and past-sequence-dependent (p-s-d) setup times are considered. Under these settings, the actual job processing times are dependent on the amount of resource allocated and the setup times are proportionate to the length of the already processed jobs. The objective function is a combination of the total completion time and the total resource consumption. In addition, the machine may need maintenance to improve its production efficiency, so the maintenance is also integrated. The optimal job sequence, the optimal amount of resource allocated to each job, and the optimal maintenance position are determined jointly. It is shown that the problem under study is polynomial time solvable.

In view of the problems existing in the prediction methods of coal and gas outburst, a method for prediction of coal and gas outburst based on multi-agent information fusion is proposed. In the method, considering the measured data relevant to many influence factors, a multi-agent information fusion model for rapid, dynamic and accurate prediction of coal and gas outburst is given, Dempster-Shafer (D-S) evidence theory is used to reduce the uncertainty and improve the accuracy in the prediction of coal and gas outburst. The results show that the proposed method has high accuracy, which is a practical method to predict coal and gas outburst. © 2010 IEEE.

Nano-TiO2 immobilized on multi-walled carbon nanotubes (MWCNTs) has been successfully prepared via sol-gel method, with an hydrochloric acid as the catalyst. The as-prepared composites were characterized by X-ray diffraction, transmission electron microscopy. It clearly showed that MWCNTs were covered with well dispersed nano-TiO2 particles. The results obtained from the visible light photocatalytic removing of methylene blue indicated that the microstructures of MWCNTs enhanced the photocatalytic activity of nano-TiO2 particles. By using MWCNTs as the supports, the phase transformation from anatase to rutile could be controlled effectively, which remarkably improved the efficiency of the photocatalytic activity during the visible light region. © 2010 IEEE.
