  • Ordering policy for two-phase deteriorating inventory system with changing deterioration rate

    The models of inventory replenishment policies for the deterioration items have been widely studied, and in most of the deterministic models, the in- transit deteriorating loss is not considered. But in operation management practice, transportation time is the major portion of the lead time, and the extent of spoilage of the fresh items is also influenced by the length of shipping time. The impact of in-transit deterioration loss to the optimal replenishment policy for deteriorating goods was studied. Firstly a in-transit and on-hand two-phase inventory model with different deterioration rate was established, then it was proved that there exists unique optimal order cycle to minimize the relevant annual cost, and the optimal order cycle is do affected by the length of transportation time and the deterioration rate in- transit. Finally, numerical examples were conducted to illustrate the effectiveness of the proposed model.

  • A deterioration diagnosis method for Li-ion battery using a transient characteristic and development of an automatic diagnosis circuit

    A deterioration diagnosis method for a Li-ion battery using its transient characteristic is proposed in this paper. The terminal voltage of the battery sharply increases at the beginning of the charging and gradually increases. The terminal voltage suddenly decreases at the end of the charging and decreases toward its internal voltage. The transient characteristic can be explained by the response of the internal impedance of the Li-ion battery. The internal impedance has a close relation to the deterioration of the battery. The proposed method in this paper diagnoses the deterioration using the integration of the difference between the terminal voltage and the internal voltage of the battery after a charging. The integrated voltage depends on both the deterioration and the temperature of the battery. The integrated voltage is corrected for the deterioration estimation of the Li-ion battery. This proposed method is practical because it requires no information except the terminal voltage of the battery and ambience temperature. A diagnosis equipment using a microcomputer has been developed in this paper. The circuit is realized a diagnosis system in low cost because the computational load for the diagnosis is light.

  • Scheduling with Job Dependent Learning Effect and Ergonomic Risk Deterioration

    In this study, new types of deterioration related to ergonomic risk factors in machine scheduling problem are investigated. By the ergonomic risk, we mean that the employees are exposed to risk of work related musculoskeletal disorders (WMSD) for the reasons of repetitive activities. Rapid The Upper Limp Assessment (RULA) was used to assess the WMSD risks. We accepted that the deterioration and the processing time are related to the ergonomic risks. Given that the learning effect is ignored and the RULA score value is equal to zero, the actual processing time is equal to the basic processing time. As the level of ergonomic risk increases, processing time is prolonged. In this study, makespan minimization on single machine scheduling problems were handled. Job dependent learning effect and ergonomic risk deterioration is included to assignment problem model. Ergonomic risks are designed as a composite risk index in the assignment problem model. The composite risk index means that effects of all the technical activities within the shift carried out are until the end of the shift. Designed assignment problem models are solved with the help of LINGO. In this study, it has been shown that the scheduling problems that are handled with composite risk-indexed deterioration and work-dependent learning effects remain solvable.

  • Development of a circuit for a deterioration diagnosis of Li-Ion battery using FFT by FPGA

    This paper presents a deterioration diagnosis circuit for Lithium ion (Li-ion) batteries using a Field Programmable Gate Array (FPGA). The terminal voltage of any Li-ion battery rapidly increases at the end of the discharging, and gradually converges to the internal voltage. The internal impedance of the battery can be obtained from the transient characteristics. The internal impedance has a close relationship with deterioration of the battery. The developed circuit diagnoses the deterioration using the frequency characteristics of the internal impedance. The internal impedance is obtained from the frequency responses converted from the transient waveforms in a time domain by Fast Fourier Transform (FFT). The developed circuit allows a quick deterioration diagnosis during operation only by measuring the battery voltage and current. The developed circuit is achieved using common devices and estimates the lifetime of the battery without using expensive measuring equipment.

  • A deterioration diagnosis method for Lithium-ion battery based on phase characteristics of internal impedance

    A deterioration diagnosis method for a Lithium-ion battery based on a phase characteristic of its internal impedance is proposed in this paper. The phase characteristic of the internal impedance is obtained from transient voltage and current waveforms of the battery by DLT (Discrete Laplace Transform). The maximum phase is increased by the deterioration. Since the phase characteristic heavily depends on temperature, a correction method is proposed to diagnose the deterioration of the battery. The proposed battery diagnostic method is independent from a contact resistance having high dependence of the implementation of the battery. The deterioration rate can be estimated from the transient voltage waveform during the operation of the battery-driven equipment. Since non-linear calculation is excluded from the proposed method, the method realizes a diagnosis system at low cost.

  • Local Inter-foil Insulation Deterioration Diagnosis and Simulation of RIP Bushing Based on FDS Method

    Resin-impregnated paper (RIP) bushings have been widely used in power system, however failure caused by local inter-foil insulation deterioration has occurred from time to time, which has seriously affected the safe and stable operation of substations. Due to the damaging effect of partial discharge, the resistance of local inter-foil insulation will gradually decrease, and breakdown may even occur. To study the phenomenon of local inter-foil insulation deterioration of RIP bushing, a test platform is established for 72.5kV RIP transformer bushings, and corresponding frequency-domain dielectric spectroscopy(FDS) test is conducted at room temperature. It is found that the FDS curve of bushing with inter-foil insulation deterioration and breakdown is significantly shifted compared to the normal one. In addition, due to the obvious development process of local inter-foil insulation deterioration of RIP bushings, a simulation model is established in this paper, and the method of changing the local electrical conductivity of local inter-foil insulation material is used to characterize the degree of insulation deterioration, and corresponding FDS response curves are obtained. The results show that with the development of the deterioration of local inter-foil insulation, the C-f and tant5-f curves have obvious transitional processes. In the initial and middle stage of insulation deterioration, the FDS method has higher diagnostic effectiveness than the traditional power frequency dielectric loss method. This article can provide a basic theoretical reference for the on-site diagnosis of local inter-foil insulation deterioration of RIP bushings.

  • Effect of insulator configuration on ageing deterioration of polymer insulators

    According to our accelerated ageing test results of 275-kV full scale insulator strings coated with the same silicone rubber, conventional porcelain long-rod insulators showed better anti-ageing performance compared with transmission line polymer insulators. As the reason for such results two factors are considered. One is difference in core diameter, and the other is difference in shed shape. In order to clarify the reason for such results, we started comparative accelerated ageing tests on five different specimens, coated with the same room temperature vulcanized silicone rubber, with almost the same shed shapes but three different core diameters and with almost the same core diameters but three different shed shapes. As of 380 cycles of accelerated ageing test, any discernible deterioration was not observed on any specimens, although partial discharges had been observed at the energized end core surface of the transmission line polymer insulator after 200 cycles. It takes so long to get any significant deterioration by the accelerated ageing test. Since it is considered that the main cause of surface deterioration of polymer insulators is partial discharges, we investigated the partial discharge inception voltages of these specimens under contaminated and wet conditions. The transmission line polymer insulator showed the lowest partial discharge inception voltage. Very large ratio of shed to core diameter is considered to be the cause of easy occurrence of partial discharges due to concentrated voltages allotted at the core surfaces. We prepared three specimens to improve the voltage distribution of the transmission line polymer insulator and evaluated. Promising results were obtained.

  • Analysis of deterioration by partial discharge of XLPE using GCMS and FTIR

    Deterioration of polymeric dielectrics by partial discharge (PD) might occur at defects in an insulation layer. To elucidate the mechanism of deterioration by PD, measurements were conducted of the gas components produced during deterioration and the substances created on the surface of cross-linked polyethylene (XLPE) samples subjected to PD. Gas component measurements were performed using an experimental apparatus including GC-MS. Results of gas analyses showed that carbon dioxide (CO<sub>2</sub>) was produced when the XLPE sample is subjected to the PD in a N<sub>2</sub>+O<sub>2</sub> gas atmosphere. The amount of generated CO<sub>2</sub> was confirmed to increase concomitantly with the period of voltage application. The FTIR spectroscopic analysis of substances on the surface of deteriorated XLPE revealed carbonyl compounds on the surface of the deteriorated samples. The deterioration was suppressed when a phenolic antioxidant was added: 44-thiobis-3methyl-6tert butyl phenol. The process of deterioration by PD and the effect of the antioxidant on the deterioration by PD were also discussed.

  • On-line deterioration prediction residual life evaluation of rotating equipment based on vibration measurement

    In this paper, an on-line deterioration prediction method and residual life evaluation are proposed for maintenance of rotating equipment. Status of the rotating equipment is inspected by vibration measurement and a mathematical model for the deterioration of the equipment is derived in order to predict future condition of the rotating equipment. For the construction of the deterioration model, outliers in the vibration data caused by measurement errors and so on are eliminated in order to improve accuracy of the deterioration model. Residual life of the rotating equipment is evaluated from the deterioration prediction by using the deterioration model. The effectiveness of the proposed deterioration prediction method and residual life evaluation are assured by actual data of rotating equipment in thermal power plants.
