Probe on Network-based Collaborative Maintenance Model for After-sales Equipment

In order to make equipment run safely, economically and continuously, some new maintenance models were put forward to improve the equipment after-sale maintenance service, such as E-maintenance, third-party maintenance, etc. To certain extent, the models solved the problem of the distance between the manufacturer and customer and the dispersion of the maintenance technologies, however, those resources are still widely distributed and do not collaborate efficiently. In this paper, a network-based collaborative maintenance service model was proposed for after-sales equipment to solve the problem of maintenance resources integration. Concretely, equipment designers, maintainers, spare parts suppliers and maintenance experts were grouped together to establish dynamic alliance. The leader of the alliance is the manufacturer under guaranty period or equipment user exceeding the guaranty period. The process of maintenance service was divided into three stages which are fault diagnosis, maintenance decision and maintenance implementation. The sub-alliances were established to carry out maintenance work at each stage. In addition, the business process of network-based collaborative maintenance was analyzed and collaborative business system for equipment＇s after-sales collaborative maintenance service was designed. In the end, an informational economics model of network-based collaborative maintenance was established to demonstrate the effectiveness of this maintenance model.

Effects of Reneging, Server Breakdowns and Vacation on a Batch Arrival Single Server Queueing System with Three Fluctuating Modes of Service

This article examines the effects of reneging, server breakdown and server vacation on the various states of the batch arrivals queueing system with single server providing service to customers in three fluctuating modes. In this queueing system, any batch arrival joins the queue if the server is busy or on vacation or under repair. However, if the server is free, one customer from the arriving batch joins the service immediately while others join the queue. In case of server breakdown, the customer whose service is interrupted returns back to the head of the queue. As soon as the server has is repaired, the server attends to the customer in mode 1. For this queueing system, customers that are impatient due to breakdown and server vacation may renege (leave the queue without getting service). Due to fluctuating modes of service delivery, the system may provide service with complete or reduced efficiency. Consequently, we construct the mathematical model and derive the probability generating functions of the steady state probabilities of several states of the system including the steady state queue size distribution. Further, we discuss some particular cases of the proposed queueing model. We present numerical examples in order to demonstrate the effects of server vacation and reneging on the various states of the system. The study revealed that an increase in reneging and a decrease in server vacation results in a decrease in server utilization and an increase in server’s idle time provided rates of server breakdown and repair completion are constant. In addition, the probability of server vacation, the probability of system is under repair and the probabilities that the server provides service in three fluctuating modes decreases due to an increase in reneging and a decrease in vacation completion rates.

Effect of precise nursing service mode on postoperative urinary incontinence prevention in patients with prostate disease

BACKGROUND Patients with benign prostatic disease often experience detrusor morphological changes and dysfunction.In severe cases,it leads to bladder detrusor dysfunction,resulting in dysuria,frequent urination,urgent urination,incomplete urination,and other symptoms including renal function injury.An operation to restore normal urination function and to control postoperative complications,as far as possible,is the most common method for benign prostatic disease.AIM To observe the effect of precise nursing service mode on postoperative urinary incontinence prevention in patients with prostate disease.METHODS In total,130 patients diagnosed with benign prostatic disease,from January 2018 to June 2021,in our hospital,were selected and divided into observation and control groups according to their treatment options.Sixty-five cases in the control group were given routine nursing mode intervention and 65 cases in the observation group received precise nursing service mode intervention.The intervention with the observation group included psychological counseling about negative emotions,pelvic floor exercises,and post-hospital discharge care.The complications of the two groups were counted,and the general postoperative conditions of the two groups were recorded.The urinary flow dynamics indexes of the two groups were detected,and differences in clinical international prostate system score(IPSS)and urinary incontinence quality of life questionnaire(I-QOL)scores were evaluated.RESULTS Postoperative exhaust time(18.65±3.23 h and 24.63±4.51 h),the time of indwelling catheter(4.85±1.08 d and 5.63±1.24 d),and hospitalization time(8.78±2.03 d and 10.23±2.28 d)in the observation group were lower than in the control group.The difference was statistically significant(P<0.05).After the operation,the maximum urinary flow rate(Qmax)increased(P<0.05),the residual urine volume(RUV)decreased(P<0.05),and the maximum closed urethral pressure(MUCP)was not statistically significant(P>0.05)compared to pre-operation.The Qmax of the observation group was higher than that of the control group,while the RUV was lower than that of the control group.There was no significant difference in MUCP between the observation and control groups(P>0.05).The I-QOL score of the two groups improved(P<0.05),and the IPSS decreased(P<0.05).After the operation,the I-QOL score of the observation group was higher than that of the control group,and the IPSS was lower than that of the control group(P<0.05).There were no significant differences in the incidence of urethral injury(1.54%and 3.08%),bladder spasm(0.00%and 1.54%),and secondary bleeding(1.54%and 4.62)between the observation and control groups(P>0.05).CONCLUSION The precise nursing service mode can reduce the incidence of postoperative urinary incontinence in patients with prostate disease,thus improving postoperative urodynamics and rehabilitation,and quality of life.

The Sensitivity of Model Results to Specification of Network-Based Level of Service Attributes: An Application of a Mixed Logit Model to Trave Mode Choice

The need for travel demand models is growing worldwide. Obtaining reasonably accurate level of service (LOS) attributes of different travel modes such as travel time and cost representing the performance of transportation system is not a trivial task, especially in growing cities of developing countries. This study investigates the sensitivity of results of a travel mode choice model to different specifications of network-based LOS attributes using a mixed logit model. The study also looks at the possibilities of correcting some of the inaccuracies in network-based LOS attributes. Further, the study also explores the effects of different specifications of LOS data on implied values of time and aggregation forecasting. The findings indicate that the implied values of time are very sensitive to specification of data and model implying that utmost care must be taken if the purpose of the model is to estimate values of time. Models estimated on all specifications of LOS-data perform well in prediction, likely suggesting that the extra expense on developing a more detailed and accurate network models so as to derive more precise LOS attributes is unnecessary for impact analyses of some policies.

The service provision mode will be more open, diversified, and individualized.

Research on the Selection of Supply Chain Marketing Models Based on E-commerce Service Levels

Based on the game theory,the service sensitivity coefficient is introduced to construct four marketing game models,which include a single flagship store,a single self-operated store,a direct sales-flagship store,and a direct sales-self-operated store,in combination with numerical analysis methods to analyze manufacturers and e-commerce platforms in different situations.The study found that the service levels affected the profit of each entity in the supply chain.The service levels of self-operated stores were higher than those of the flagship stores,and the opening of direct sales channels had a stimulating effect on the service levels of e-commerce platforms to a certain extent.In consideration of the service levels and the ability to build direct sales channels,the direct sales-flagship store marketing model is the best choice for manufacturers whereas e-commerce platforms are more inclined to open self-operated stores.However,the opening of manufacturers'direct sales channels is not necessarily beneficial to e-commerce platforms.

A tour-based analysis of travel mode choice accounting for regional transit service

The aim of this work is to explore the impact of regional transit service on tour-based commuter travel behavior by using the Bayesian hierarchical multinomial logit model, accounting for the spatial heterogeneity of the people living in the same area.With two indicators, accessibility and connectivity measured at the zone level, the regional transit service is captured and then related to the travel mode choice behavior. The sample data are selected from Washington-Baltimore Household Travel Survey in 2007,including all the trips from home to workplace in morning hours in Baltimore city. Traditional multinomial logit model using Bayesian approach is also estimated. A comparison of the two different models shows that ignoring the spatial context can lead to a misspecification of the effects of the regional transit service on travel behavior. The results reveal that improving transit service at regional level can be effective in reducing auto use for commuters after controlling for socio-demographics and travel-related factors.This work provides insights for interpreting tour-based commuter travel behavior by using recently developed methodological approaches. The results of this work will be helpful for engineers, urban planners, and transit operators to decide the needs to improve regional transit service and spatial location efficiently.
