Creating Capacity To Accommodate Additional Cardiac Catheterization Procedures, Kristin Anthony

Operations Transformation

Patient access to diagnostic outpatient (OP) cardiac catheterization is limited by a perceived lack of capacity. Outpatient cardiac cath pts flow through the ACU for pre/post procedure care. Current schedule limits pts that may be scheduled through the ACU to two OP procedures/day. Cardiologists request the ability to schedule beyond the two procedures/day allowed. Significant variation in pre/postoperative care orders exist amongst cardiologists resulting in variability in length of stay. Cardiac procedures are booked either as 60/90/120 minutes – Epic case averaging technology is not active in the cath lab. As a result, the case minutes in the cath lab …

Organizational Methods Of Reducing Burnout: The Impact Of Self-Rostering On Work-Life-Integration, Cory Authement

MSN Capstone Projects

With burnout being at an all-time high, organizations must find new ways to prioritize staff wellbeing and promote work-life balance. According to the Emergency Nurses Association (ENA) turnover in emergency departments ranges from 15-30% within the first year of nursing, and 43% within the first three years (Roncallo et al., 2020). These turnover rates cost a 300-bed facility approximately four million dollars in annual expenditure (Hesse, 2016). This level of loss and expenditure is unsustainable for the future of nursing and diverts resources away from our patients.

In recent studies, it was shown that burnout leads to difficulties for nurses …

Multitasking Scheduling With Shared Processing, Bin Fu, Yumei Huo, Hairong Zhao

Computer Science Faculty Publications and Presentations

Recently, the problem of multitasking scheduling has raised a lot of interest in the service industries. Hall et al. (Discrete Applied Mathematics, 2016) proposed a shared processing multitasking scheduling model which allows a team to continue to work on the primary tasks while processing the routinely scheduled activities as they occur. With a team being modeled as a single machine, the processing sharing of the machine is achieved by allocating a fraction of the processing capacity to routine jobs and the remaining fraction, which we denote as sharing ratio, to the primary jobs. In this paper, we generalize this model …

Improving Opportunities For Students By Creating Pathways For Taking Art, Denise Hingst

Master's Theses & Capstone Projects

According to research, art education has gone through a decline, causing a lack of opportunities for students to experience the development of creativity in the general classroom. These opportunities for students in the schools in this study become even harder at the secondary level. With these small schools, it falls on the leadership of the administration to solve the scheduling dilemma for all the students. A school improvement plan is put into place to help increase the pathways for taking art by extending the day at one of the schools and changing the schedules to better help both schools work …

Dynamic Scheduling With Uncertain Job Types, Zuo-Jun Max Shen, Jingui Xie, Zhichao Zheng, Han Zhou

Research Collection Lee Kong Chian School Of Business

Uncertain job types can arise as a result of predictive or diagnostic inaccuracy in healthcare or repair service systems and unknown preferences in matching service systems. In this paper, we study systems with multiple types of jobs, in which type information is imperfect and will be updated dynamically. Each job has a prior probability of belonging to a certain type which may be predicted by data, models, or experts. A job can only be processed by the right machine, and a job assigned to the wrong machine must be rescheduled. More information is learned from the mismatch, and job type …

A Data-Driven Approach For Scheduling Bus Services Subject To Demand Constraints, Brahmanage Janaka Chathuranga Thilakarathna, Thivya Kandappu, Baihua Zheng

Research Collection School Of Computing and Information Systems

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 …

Streaming Approximation Scheme For Minimizing Total Completion Time On Parallel Machines Subject To Varying Processing Capacity, Bin Fu, Yumei Huo, Hairong Zhao

Computer Science Faculty Publications and Presentations

We study the problem of minimizing total completion time on parallel machines subject to varying processing capacity. In this paper, we develop an approximation scheme for the problem under the data stream model where the input data is massive and cannot fit into memory and thus can only be scanned a few times. Our algorithm can compute an approximate value of the optimal total completion time in one pass and output the schedule with the approximate value in two passes.

Reinforcement Learning Approach To Solve Dynamic Bi-Objective Police Patrol Dispatching And Rescheduling Problem, Waldy Joe, Hoong Chuin Lau, Jonathan Pan

Research Collection School Of Computing and Information Systems

Police patrol aims to fulfill two main objectives namely to project presence and to respond to incidents in a timely manner. Incidents happen dynamically and can disrupt the initially-planned patrol schedules. The key decisions to be made will be which patrol agent to be dispatched to respond to an incident and subsequently how to adapt the patrol schedules in response to such dynamically-occurring incidents whilst still fulfilling both objectives; which sometimes can be conflicting. In this paper, we define this real-world problem as a Dynamic Bi-Objective Police Patrol Dispatching and Rescheduling Problem and propose a solution approach that combines Deep …

Hybrid Tabu Search Algorithm For Unrelated Parallel Machine Scheduling In Semiconductor Fabs With Setup Times, Job Release, And Expired Times, Changyu Chen, Madhi Fathi, Marzieh Khakifirooz, Kan Wu

Research Collection School Of Computing and Information Systems

This research is motivated by a scheduling problem arising in the ion implantation process of wafer fabrication. The ion implementation scheduling problem is modeled as an unrelated parallel machine scheduling (UPMS) problem with sequence-dependent setup times that are subject to job release time and expiration time of allowing a job to be processed on a specific machine, defined as: R|rj,eij,STsd|Cmax. The objective is first to maximize the number of processed jobs, then minimize the maximum completion time (makespan), and finally minimize the maximum completion times of the non-bottleneck machines. A mixed-integer programming (MIP) model is proposed as a solution approach …
