In this paper we present an integrated nurse staffing and scheduling system for analyzing nurse workforce management policies. A mixed-integer linear programming nurse staffing model is used to determine aggregate labor requirements for a 6-month planning horizon. Subsequently, a mixed-integer linear programming model is used to disaggregate the nurse staffing plan into 2-week labor schedules. ...
This paper compares data envelopment analysis (DEA) and ratio analysis as alternative tools for assessing the performance of organisational units such as bank branches and schools. Such units typically use one or more resources to secure one or more outputs, the inputs and/or outputs being possibly incommensurate. The assessment of District Health Authorities in England on the provision of perinatal...
When a coronary care unit becomes full, an existing patient will be transferred out of intensive care and into a general medical or surgical ward in order to make room for the next arrival. The patient transferred may have suffered a heart attack and still be at risk whilst the next patient admitted may subsequently be diagnosed to have nothing more serious than indigestion. Queueing theory is used...
The purpose of quality management in hospitals is to establish a system that measures and manages patient care in a way that provides the optimal care for all patients. This study empirically explores the relationship between hospital quality management and service quality performance for a sample of US community hospitals using a path analytic model. The research reveals strong relationships between...
In this paper, an Erlang-based stochastic model for patient flow is presented. The model is proposed as an effective tool to obtain analytic results for the stochastic process of patient flow in a health care environment. Through the use of two previously published examples, it is shown that the stochastic model can be developed quickly, is not computationally intensive and provides a good representation...
Elective surgery management typically deals with a queue of patients that have to be scheduled for surgery within a certain time frame, considering both medical and economic constraints. In order to prevent the patient queue and waiting times from growing, surgery management has to decide whether to temporarily increase patient throughput at the regional hospital or have some patients scheduled for...
The Balanced Scorecard (BSC) methodology focuses on major critical issues of modern business organisations: the effective measurement of corporate performance and the evaluation of the successful implementation of corporate strategy. Despite the increased adoption of the BSC methodology by numerous business organisations during the last decade, limited case studies concern non-profit organisations...
This paper examines a single machine scheduling problem of minimizing the maximum scheduling cost that is nondecreasing with job completion time. Job release dates and precedence constraints are considered. We assume that each job can be processed exactly once without preemption. This is a classical scheduling problem, and is specifically useful in the scheduling of medical treatments. We develop...
Motivated by a proposal of the local authority for improving the existing healthcare system in the Parana State in Brazil, this article presents an optimization-based model for developing a better system for patients by aggregating various health services offered in the municipalities of Parana into some microregions. The problem is formulated as a multi-objective partitioning of the nodes of an undirected...
This paper addresses a real-life public patient transportation problem derived from the Hong Kong Hospital Authority (HKHA), which provides ambulance transportation services for disabled and elderly patients from one location to another. We model the problem as a multi-trip dial-a-ride problem (MTDARP), which requires designing several routes for each ambulance. A route is a sequence of locations,...
