In order to explore the factors affecting users’ behaviors in a free-floating bike sharing (FFBS) system China, survey was conducted Jiangsu province, China 2017, and travel characteristics of FFBS users were analyzed. A binary logistic model applied quantify impact various variables regarding residents’ usage preference based on 30401 valid questionnaires. The findings show that (1) mainly used for short-distance cities, especially commuting schooling, time period coincided with rush-hour...

This paper presents a closed queuing network model to address bike queues in bike-sharing systems with finite docks. The tackles issues of spillover and user attrition due fully occupied docks shortages at stations. objective is determine throughput rates other performance metrics for these systems. To overcome computational challenges, we propose an approximation algorithm based on the developed model. Our analysis reveals intrinsic properties docks: (i) effective system rate increases...

SUMMARY Emergency evacuation in congested urban networks can be influenced by uncertain background travel demands, but this issue has not been fully investigated. In study, links are prepared for exclusive use evacuees. Under assumption, an integrated model is proposed determining flows on emergency routes and traffic signals at intersections the presence of demands. The problem formulated as a bi‐objective bi‐level programming based concept robust optimization. It assumed that demands...

In this work, a comprehensive three-dimensional numerical model was developed to simulate the coal-fired chemical looping combustion (CLC) process using ilmenite as oxygen carrier in pressurized circulating fluidized bed (CFB) fuel reactor. Both gas–solid flow and reactions were considered. The contain steam gasification of coal subsequent reduction intermediate products with carrier. This predicted main features complex behaviors from velocity voidage profiles. concentrations components,...

Corporate Environment Management (CEM) is one of the most critical areas for encouraging truck fleets to adopt green logistics activities under serious situation energy security and emission pressures. However, CEM has not been widely adopted in road freight transportation industry China yet. This paper describes practices identifies factors which will have significant effect on adoption fleets. A research framework was developed based theory institutional economics, used describe concept...

This study focuses on the route selection problem of multimodal transportation: When facing a shortage containers, transport plan must be designed for freight forwarders that realizes optimal balance between transportation time and cost. is complicated by two important characteristics: (1) The use containers related to routes, they interact with each other; (2) Different types should used in different ranges modes transportation. To solve this problem, we establish multi-objective...

Purpose: With the rapid expansion in use of intelligent voice assistants (IVAs) people's daily lives, how to improve users' continuous intention is crucial for sustainable development technology. Utilizing stimulus-organism-response (S-O-R) framework, we propose a theoretical model examine three dimensions interactivity (ie, two-way communication, responsiveness, perceived control) impact individuals' affective reactions psychological ownership, subjective well-being) and continuance IVAs...

This paper aims to design a robust waste cooking oil- (WCO-) for-biodiesel supply chain under WCO and price as well biodiesel demand uncertainties, so improve biorefineries’ ability cope with the poor environment. A regional is firstly introduced based on biggest WCO-for-biodiesel company in Changzhou, Jiangsu province, it comprises three components: supplier, biorefinery, zone. And then mixed integer linear model multiple objectives (economic, environmental, social objectives) proposed for...

Free-floating bike sharing (FFBS) is an innovative mode of bicycle operation that has grown rapidly in China. This paper studies the attitude and travel behavior free-floating Nanjing. Questionnaires were sent by field survey. Investigators go on streets, subway stations, shopping malls, campus to distribute questionnaires. A total 700 questionnaires issued, data from 453 users analyzed. The questionnaire analyzed find out attraction for citizens Nanjing, including time distance...

Biofuel production in China suffers from many uncertainties due to concerns about the government’s support policy and supply of biofuel raw material. Predicting is critical development this energy industry. Depending on biofuel’s characteristics, we improve prediction precision conventional method by creating a dynamic fuzzy grey–Markov model. Our model divides random time series decomposition into change trend sequence fluctuation sequence. It comprises two improvements. We overcome problem...

In situ gasification chemical looping combustion (iG-CLC) is a promising coal technology for implementing CO2 capture with low energy penalty. A novel iG-CLC cold experimental system was developed in the authors' previous work (Ind. Eng. Chem. Res. 2013, 52, 14208). It mainly consists of high-flux circulating fluidized bed (HFCFB) riser as fuel reactor and cross-flow moving air reactor. As an extension that work, this study, we further optimized by redesignung to enhance carrying capacity...

Carpooling, as an emerging travel mode, has not yet been paid sufficient attention despite its merits of convenience, cost-efficiency, and sustainability. The studies carpooling, especially on the factors influencing are inadequate. To tackle this problem, what how influence travelers' mode choice studied with a practical trial. Based qualitative survey, we found that time, cost, safety, punctuality, comfort, social contact, identity promotion potential factors. Then stated preference (SP)...

Experimental studies on flow patterns and transitions were carried out in a visible multiple-spouted bed. The bed combines three spouted cells, each with cross-section of 100 × 30 mm, cell has an independent spout nozzle 10 mm width. Polypropylene beads density 900 kg/m3 mean diameter 2.8 used as materials. Six distinct patterns, i.e., fixed (FB), internal jet (IJ), bubble (IJB), single spouting (SS), multi-spouting (MS), slugging (IJS), determined the basis criteria well schematic diagrams...

The analysis of factors influencing urban rail transit (URT) passenger flow is often a precondition for establishing prediction models. Much past has focused on correlation and does not draw research causal mechanisms. In this paper, novel inference method based transfer information entropy (TIE) proposed to determine the causality between influence factor URT flow. As comparison, matrix coefficient (RV2 coefficient) used analyze correlation. Taking system in Xi'an, Shaanxi, China, as an...
