“…Second, to focus on the main research issues related to the effect of interchangeable design confronted in remanufacturing processing, this paper does not consider how the proposed mathematical formulation for product design can be integrated with product development technologies. However, Rashid et al [48] and Rashid et al [49] suggest that the product development technologies, particularly real-time optimization and economic control of production processes, can illustrate the improvement in economic performance under product design. As such, future researchers can extend models of this paper to address how the proposed mathematical formulation for product design can be integrated with product development technologies, such as real-time optimization and economic control of production processes.…”

Traditional wisdom suggests that the interchangeable design in process system engineering, such as modularity or commonality design, can lower the manufacturing cost and act as a revenue driver. Moreover, the interchangeable design will be efficient in both assembling for new production and disassembling for remanufacturing. As such, interchangeable design confronted remanufacturing processing often involves a balance of revenue from cost drivers and cannibalization effects from remanufacturing. Therefore, this paper studies how the original equipment manufacturers’ (OEMs’) interchangeable design impacts the remanufacturing decisions, as well as the economy and environment. Specifically, we develop two theoretical models, in which an OEM makes a strategic choice relating to design interchangeability when the remanufacturing operations are undertaken by itself (Model O) or outsourced to third-party remanufacturers (Model T). This study finds that, although the optimal level of interchangeability related to the product design in Model T is lower than that in Model O, the optimal quantity of remanufactured products in the latter scenario is always higher. This suggests that remanufacturing outsourcing deters the OEM’s strategic choice on design interchangeability, which may be consistent with the fact that Lexmark makes its products less interchangeable to avoid remanufacturing from third-party remanufacturers (TPRs). Conversely, although the OEM is always less likely to outsource its remanufacturing operations to independent remanufacturers, remanufacturing outsourcing may be more beneficial for the environment, industry, and society. These key insights on the environmental groups or agencies suggest that remanufacturing outsourcing may be more beneficial for the environment, industry, and society and depends on the OEMs’ attitudes towards its profitability loss. Furthermore, to eliminate the above contrasting effects between the OEMs’ profitability and other issues, two possible remedies, including a revenue-sharing contract and subsidy-incentive mechanism, are provided to achieve a “win-win” situation.

“…Thus, the precise diagnosis of incipient faults is a popular and difficult problem in the field of fault diagnosis. To solve this problem, domestic and foreign scholars have conducted some exploratory studies, mainly modeling and analyzing incipient faults based on analytical models, knowledge and data‐driven models 9,10 .

In order to overcome the shortcomings of concealed early fault features of rolling bearings which can not be better recognized and the accuracy of early fault diagnosis is not high enough, a novel collaborative diagnosis method is presented combing with variational modal decomposition (VMD) and stochastic configuration network (SCN) for incipient faults of rolling bearing. First, decomposing the original signal by VMD, and then extracting peak-to-peak of intrinsic mode function component from each fault, and calculating sample entropy of peak-to-peak to construct characteristic sample of fault. Second, based on VMD composition, proposing an incipient fault diagnosis method which is named SCN. Finally, compared with other classification methods, the results show that the proposed collaborative method is effective and advantageous.

“…The PTA production process was a typical heterogeneous azeotropic distillation system; the steady-state PTA simulation production process [10][11][12] was demonstrated elsewhere. However, among the variables of multiphase azeotropic distillation [13,14], the coupling was serious, characterized 2 of 16 by parameter sensitivity, multistability, nonlinearity [15][16][17], and, usually, nonconvergence, thereby greatly increasing the difficulty of control; some predictive control models were applied to solve these problems [18,19]. The importance of dynamic performance analysis of the HAc dehydration process was increasingly obvious.…”

In this study, a solvent dehydration column of purified terephthalic acid (PTA) plant was used as the research object. Based on a dynamic model of the solvent dehydration column, a dynamic sensitivity analysis of the key parameters was carried out using Aspen Dynamics. After the dynamic model reached stability, the reflux rate, methyl acetate concentration, and reflux temperature of the solvent dehydration column were adjusted and the changes of the key separation indexes under the corresponding disturbance were analyzed. According to the analysis results, a sensitive plate temperature controller was added to carry out the dynamic sensitivity analysis. In addition, the acetic acid (HAc) concentration of the bottom of the column was found to be unstable in the dynamic sensitivity analysis. Considering the HAc concentration controller of the column bottom, two control strategies were designed. By analyzing the dynamic response of the feed flow disturbance under different control strategies, a more suitable control strategy under different conditions was obtained. From this, a reasonable method could be derived to design the control strategy, thereby providing a theoretical basis for further real-time optimization and advanced control of solvent dehydration in a PTA plant.
