Passenger satisfaction is extremely important for the success of a public transportation system. Many studies have shown that passenger satisfaction strongly depends on the time they have to wait at the bus stop (waiting time) to get on a bus. To be specific, user satisfaction drops faster as the waiting time increases. Therefore, service providers want to provide a bus to the waiting passengers within a threshold to keep them satisfied. It is a two-pronged problem: (a) to satisfy more passengers the transport planner may increase the frequency of the buses, and (b) in turn, the increased frequency may impact …

Beyond Service Education: Impacting The Human Experience With Sustained Training Utilizing The Experience Model Of Communication, Jennifer S. Packard, Rebecca A. Brustad, Jane M. Hoplin, Sheila K. Stevens

Patient Experience Journal

Patients scheduling or checking in for medical appointments often share with frontline employees’ details of their stories, including their worries, prior negative experiences, and hopes. These interactions require employees to not only complete their task, but also to be mindfully present, picking up on important social cues and showing appropriate emotional congruence and empathic understanding. Based on a review of recorded patient calls, a gap was identified in the communication skills of desk and scheduling staff at this large academic medical center, and a sustained training program was created to fill this gap. The training is centered on an evolving …

Towards A Novel Tournament Scheduling Algorithm And Statistical Measure Of Team Equity In Large Scale Forensic Tournaments, Mark Kokoska Oct 2020

Towards A Novel Tournament Scheduling Algorithm And Statistical Measure Of Team Equity In Large Scale Forensic Tournaments, Mark Kokoska

Proceedings of the National Developmental Conference on Individual Events

Business items raised at recent national forensics tournaments regarding scheduling seem to be based around issues of an increased number of competitors and a trend for some schools to have a disproportionate amount of competitors in a single event. This paper examines the stated goals in scheduling a tournament as a device that measures the ability of competitors. Stemming from these goals, this paper proposes a novel random scheduling algorithm capable of scheduling a large number of competitors in an individual event. After implementing this algorithm, its performance is measured in relation to its ability to schedule a tournament comparable …

Online Traffic Signal Control Through Sample-Based Constrained Optimization, Srishti Dhamija, Alolika Gon, Pradeep Varakantham, William Yeoh

Research Collection School Of Computing and Information Systems

Traffic congestion reduces productivity of individuals by increasing time spent in traffic and also increases pollution. To reduce traffic congestion by better handling dynamic traffic patterns, recent work has focused on online traffic signal control. Typically, the objective in traffic signal control is to minimize expected delay over all vehicles given the uncertainty associated with the vehicle turn movements at intersections. In order to ensure responsiveness in decision making, a typical approach is to compute a schedule that minimizes the delay for the expected scenario of vehicle movements instead of minimizing expected delay over the feasible vehicle movement scenarios. Such …

Cross-docking is considered as a method to manage and control the inventory flow, which is essential in the context of supply chain management. This paper studies the integration of the vehicle routing problem with cross-docking, namely VRPCD which has been extensively studied due to its ability to reducethe overall costs occurring in a supply chain network. Given a fleet of homogeneous vehicles for delivering a single type of product from suppliers to customers through a cross-dock facility, the objective of VRPCD is to determine the number of vehicles used and the corresponding vehicle routes, such that the vehicleoperational and transportation …


Secondary Student Schedule Changes: Accountability Issues In School Counseling Program Management, Tarrell Awe, Agahe Portman, Susannah Wood, Anna Vivianni Apr 2020

Secondary Student Schedule Changes: Accountability Issues In School Counseling Program Management, Tarrell Awe, Agahe Portman, Susannah Wood, Anna Vivianni

Journal of Counseling Research and Practice

Descriptive data collected on student schedule changes have been missing in the literature. School counselors agree the task of changing schedules is overwhelming, but there is no measure indicating the extent of time and attention devoted to schedule changes. The purpose of this article is to present data gathered during the crucial schedule change period just prior to the beginning of a new academic term. The findings may provide an incentive for school counselors to begin collecting data related to scheduling and establish concrete measures for providing information for dissemination to school district decision makers.

Training Student Workers For Cross-Departmental Success In An Academic Library: A New Model, Kindra Becker-Redd, Kirsten Lee, Caroline Skelton

Library Staff Publications

Many academic libraries rely on a student workforce for everyday operations, interacting with patrons, and assistance with larger projects. Training these students for such multifaceted and customer-service-focused positions can be a challenge. This article traces an overhaul of training procedures made during the transition to a centralized, services desk workflow. All aspects of training a large student workforce, from planning and presentation to assessment, are outlined. Interactive group sessions and peer-to-peer reinforcement of procedures have proven to be most effective in training student workers for varied roles in an academic library.

Channel Autocorrelation-Based Dynamic Slot Scheduling For Body Area Networks, Hongyun Zhang, Farzad Safaei, Le Chung Tran Jan 2018

Channel Autocorrelation-Based Dynamic Slot Scheduling For Body Area Networks, Hongyun Zhang, Farzad Safaei, Le Chung Tran

Faculty of Engineering and Information Sciences - Papers: Part B

As a promising technology in the context of m-health and e-medical, wireless body area networks (WBANs) have a stringent requirement in terms of transmission reliability. Meanwhile, the wireless channel in WBANs is prone to deep fading due to multiple reasons, such as shadowing by the body, reflection, diffraction, and interference. To meet the challenge in transmission reliability, the dynamic slot scheduling (DSS) methods have attracted considerable interest in recent years. DSS method does not require extra hardware or software overhead on the sensor side. Instead, the hub optimizes the time-division multiple access slots by selecting the best permutation at the …

Cross-Elasticities In Frequencies And Ridership For Urban Local Routes, Joseph Totten, David Levinson Sep 2016

Cross-Elasticities In Frequencies And Ridership For Urban Local Routes, Joseph Totten, David Levinson

Journal of Public Transportation

Observational data from the Minneapolis-Saint Paul region’s Metro Transit were analyzed to determine the effects of service levels on ridership levels at different intervals. The research compares changes in service levels and ridership in several service intervals and includes elasticities and cross elasticities, or the influence that these service levels have on different service intervals’ ridership. These cross-elasticities were found to have little effect during the week; however, weekend ridership was found to be influenced by rush-hour and overnight frequencies.

On Transformation Of Query Scheduling Strategies In Distributed And Heterogeneous Database Systems, Janusz R. Getta, - Handoko

Faculty of Engineering and Information Sciences - Papers: Part A

This work considers a problem of optimal query processing in heterogeneous and distributed database systems. A global query sub- mitted at a local site is decomposed into a number of queries processed at the remote sites. The partial results returned by the queries are in- tegrated at a local site. The paper addresses a problem of an optimal scheduling of queries that minimizes time spend on data integration of the partial results into the final answer. A global data model defined in this work provides a unified view of the heterogeneous data structures located at the remote sites and a …


An Effective Asexual Genetic Algorithm For Solving The Job Shop Scheduling Problem, Mehrdad Amirghasemi, Reza R. Zamani Jan 2015

An Effective Asexual Genetic Algorithm For Solving The Job Shop Scheduling Problem, Mehrdad Amirghasemi, Reza R. Zamani

Faculty of Engineering and Information Sciences - Papers: Part A

All rights reserved. Abstract By using the notion of elite pool, this paper presents an effective asexual genetic algorithm for solving the job shop scheduling problem. Based on mutation operations, the algorithm selectively picks the solution with the highest quality from the pool and after its modification, it can replace the solution with the lowest quality with such a modified solution. The elite pool is initially filled with a number of non-delay schedules, and then, in each iteration, the best solution of the elite pool is removed and mutated in a biased fashion through running a limited tabu search procedure. …

Faculty of Engineering and Information Sciences - Papers: Part A

In this paper, a stochastic multiobjective framework is proposed for a day-ahead short-term Hydro Thermal Self-Scheduling (HTSS) problem for joint energy and reserve markets. An efficient linear formulations are introduced in this paper to deal with the nonlinearity of original problem due to the dynamic ramp rate limits, prohibited operating zones, operating services of thermal plants, multi-head power discharge characteristics of hydro generating units and spillage of reservoirs. Besides, system uncertainties including the generating units' contingencies and price uncertainty are explicitly considered in the stochastic market clearing scheme. For the stochastic modeling of probable multiobjective optimization scenarios, a lattice Monte …


Rural Pediatric Primary Care Practice Patterns As A Result Of An On-Site Behavioral Health Consultant: A Retrospective Analysis, Kayla D. Mccarter May 2014

Rural Pediatric Primary Care Practice Patterns As A Result Of An On-Site Behavioral Health Consultant: A Retrospective Analysis, Kayla D. Mccarter

Undergraduate Honors Theses

Nationally, it has been estimated that 10 to 21% of children with psychosocial concerns are seen in primary care settings (Jellinek et al., 1999; McInerny, Szilagyi, Childs, Wasserman & Kelleher, 2000; Palermo et al., 2002). Often, however, children go undiagnosed with/treated for psychosocial concerns in pediatric primary care due to lack of physician time and poor referral rates to mental health providers. Evaluations of integrated care models, in which a behavioral health consultant is present in primary care practices, has shown to increase the availability of mental health services (Stancin, Perrin, & Ramirez, 2009). Using extant data from patient records …

The paper further elaborates on the …


Using A Mobile Device To Deliver Visual Schedules To Young Children With Autism, Leslie Nelson Aug 2013

Using A Mobile Device To Deliver Visual Schedules To Young Children With Autism, Leslie Nelson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Young children with autism spectrum disorder (ASD) frequently display an inability to self-regulate (use materials appropriately and refrain from self-stimulatory behavior) and self-monitor (complete each step in a task before continuing to the next step) their behavior and therefore experience a great deal of failure within their respective school and home environments and frequently end up receiving instruction in restrictive, self-contained classrooms. Visual schedules have been used to help students with ASD self-regulate their behaviors in academic and community settings (NPDC, 2010; NSR, 2009). The purpose of this study was to determine whether high-tech visual schedules increase the self-regulation and …


Rationalizing Creativity—Rationalizing Public Service: Is Scheduling Management Fit For The Digital Era?, Ann-Marie Murray May 2013

Rationalizing Creativity—Rationalizing Public Service: Is Scheduling Management Fit For The Digital Era?, Ann-Marie Murray

Articles

In public broadcast organizations across Europe, scheduling has been transformed from a marginal, administrative activity to a highly strategic management tool (Hellman, 1999; Hujanen, 2002; Meier, 2003;Ytreberg, 2000) Ellis (2000)described it as “the locus of power in television,” organizing production and managing budgets (p. 26). The role of scheduling in public broadcast organizations today reflects the demands of increasing competition and political pressure for efficiency and accountability. However, new challenges have emerged in the transition from public service broadcasting to public service media (PSM). PSM providers must redefine their mission for the digital era and find …


Integrating Iterative Crossover Capability In Orthogonal Neighborhoods For Scheduling Resource-Constrained Projects, Reza Zamani Jan 2013

Integrating Iterative Crossover Capability In Orthogonal Neighborhoods For Scheduling Resource-Constrained Projects, Reza Zamani

Faculty of Engineering and Information Sciences - Papers: Part A

An effective hybrid evolutionary search method is presented which integrates a genetic algorithm with a local search. Whereas its genetic algorithm improves the solutions obtained by its local search, its local search component utilizes a synergy between two neighborhood schemes in diversifying the pool used by the genetic algorithm. Through the integration of these two searches, the crossover operators further enhance the solutions that are initially local optimal for both neighborhood schemes; and the employed local search provides fresh solutions for the pool whenever needed. The joint endeavor of its local search mechanism and its genetic algorithm component has made …

Mip-Based Stochastic Security-Constrained Daily Hydrothermal Generation Scheduling, J Aghaei, M Karami, K M. Muttaqi, A Ahmadi, H A. Shayanfar

Faculty of Engineering and Information Sciences - Papers: Part A

This paper presents the application of a mixedinteger programming (MIP) approach for solving stochastic security-constrained daily hydrothermal generation scheduling (SCDHGS). Power system uncertainties including generating units and branch contingencies and load uncertainty are explicitly considered in the stochastic programming of SCDHGS. The roulette wheel mechanism and lattice Monte Carlo simulation (LMCS) are first employed for random scenario generation wherein the stochastic SCDHGS procedure is converted into its respective deterministic equivalents (scenarios). Then, the generating units are scheduled through MIP over the set of deterministic scenarios for the purpose of minimizing the cost of supplying energy and ancillary services over the …


Fairness And Capacity Analysis Of Opportunistic Feedback Protocol With Proportional Fair Or Maximum Throughput Scheduling, Hang Li, Qinghua Guo, Licai Fang, Defeng (David) Huang Jan 2012

Fairness And Capacity Analysis Of Opportunistic Feedback Protocol With Proportional Fair Or Maximum Throughput Scheduling, Hang Li, Qinghua Guo, Licai Fang, Defeng (David) Huang

Faculty of Engineering and Information Sciences - Papers: Part A

An opportunistic feedback protocol with maximum throughput (MT) scheduling has been proposed in the literature to achieve multiuser diversity for the downlink transmission of a wireless system, and its system capacity has been analyzed with the assumption that the received signal-to-noise ratios (SNRs) for the users are independent and identically distributed. In this paper, fairness and capacity performances of the opportunistic feedback protocol are analyzed for SNRs with independent but not necessarily identical distributions. In addition to MT scheduling, we also analyze the fairness and capacity performances for proportional fair (PF) scheduling. Compared with MT scheduling, numerical results demonstrate that …

Optimization Models And Approximate Algorithms For The Aerial Refueling Scheduling And Rescheduling Problems, Sezgin Kaplan Apr 2011

Optimization Models And Approximate Algorithms For The Aerial Refueling Scheduling And Rescheduling Problems, Sezgin Kaplan

Engineering Management & Systems Engineering Theses & Dissertations

The Aerial Refueling Scheduling Problem (ARSP) can be defined as determining the refueling completion times for fighter aircrafts (jobs) on multiple tankers (machines) to minimize the total weighted tardiness. ARSP can be modeled as a parallel machine scheduling with release times and due date-to-deadline window. ARSP assumes that the jobs have different release times, due dates, and due date-to-deadline windows between the refueling due date and a deadline to return without refueling. The Aerial Refueling Rescheduling Problem (ARRP), on the other hand, can be defined as updating the existing AR schedule after being disrupted by job related events including the …
