Quality cost in bus operations based on activity-based costing

The study of service quality and its implication for transport contracts has several approaches in research and practical applications, where the main emphasis is the consideration of quality from the user's point of view, thus obtaining a customer satisfaction index as a measurement of the overall quality with no further implications for service providers. The main aim of this paper is to estimate the real economic impact of improving quality attributes for a bus operator. An application of the activity-based costing methodology is developed for a bus contract in Madrid, using quality data from surveys together with economic and performance information, and focusing on headway as a quality variable. Results show the consistency and practicality of this methodology, overcoming simplifications from traditional procedures. This method is a powerful tool in quality-based contracting as well as for effective investment in transport quality under poverty funding constraints

Caracterización y análisis del coste de mejora de la calidad de servicio en transporte urbano en autobús, basado en la metodología ABC (activity based costing)

El estudio de la calidad de servicio en transporte público ha tenido distintos enfoques, tanto en la investigación como en sus aplicaciones prácticas, tales como el desarrollo del método SERVQUAL, los proyectos QUATTRO y EQUIP de la Comisión Europea, el Transit Capacity and Quality of Service Manual y finalmente el estándar EN 13816, siendo la consideración principal la calidad desde el punto de vista del usuario, es decir, la calidad percibida, cuyo objetivo en la práctica trata de obtener un Índice de Satisfacción del Cliente como medida de la calidad global. Esta aproximación deja de lado aspectos tanto sobre calidad suministrada como sobre los suministradores del servicio, las administraciones y los operadores, particularmente en cuanto a las implicaciones económicas. El objetivo principal de la presente tesis es la estimación del impacto económico real de la mejora de atributos de calidad para un operador de autobús urbano. En el capítulo 2, se lleva a cabo un análisis del estado del arte sobre el estudio de la calidad, tanto de los métodos de estudio, como de su aplicación al campo de transporte público, y, específicamente, del estudio de costes. En los capítulos 3 y 4 se propone la aplicación de la metodología ABC (Activity Based Costing) para el caso de un contrato de servicio de transporte público en autobús en la Comunidad de Madrid, concretamente la conexión de Tres Cantos. Para ello se utilizan datos de encuestas de calidad esperada y percibida por los usuarios, junto con información económica y de actividad, así como entrevistas a personal de la empresa, conformando todo ello una metodología compacta de investigación y análisis. Los resultados de las encuestas y los análisis posteriores identificaron la frecuencia de servicio, la puntualidad de los autobuses y la seguridad de la conducción como las tres variables mas importantes desde el punto de vista del usuario, y ha sido en referencia a estas tres variables sobre las que se ha desarrollado la aplicación del método ABC contenida en el capítulo 5. Los resultados descritos en el capítulo 6 muestran la consistencia y la aplicabilidad de esta metodología, superando las simplificaciones de los procedimientos tradicionales contables. En cuanto a los resultados obtenidos, se ha comprobado que una aproximación tradicional basada en costes por kilometro puede llegar a sobrevalorar los costes asociados a mejoras de calidad hasta tres veces los costes calculados según el método ABC. Finalmente en el capítulo 7 se recogen las principales conclusiones y se apuntan algunas líneas futuras de investigación basadas en mejoras sobre la aplicación y transferibilidad de los resultados. The study of service quality and its implication for transport contracts has several approaches in research and practical applications, such as the development of the SERVQUAL method, the UE QUATTRO and EQUIP research projects, the Transit Capacity and Quality of Service Manual and finally the EN 13816 standard. In all cases the main stream is the consideration of quality from the user’s point of view, thus obtaining a Customer Satisfaction Index as a measurement of the overall service quality. This approach ignores quality consequences for transport providers, authorities and operators, particularly economic implications. The main target of this thesis is to estimate the real economic impact of improving quality attributes for a bus operator. Chapter 2 includes a thorough analysis of the state of the art of general methodologies on service quality, their applications for public transport, and particularly for quality costing. In chapters 3 and 4, the Activity Based Costing (ABC) methodology is proposed for a suburban bus contract in Madrid, Tres Cantos. Perceived and expected quality surveys are used together with economic and performance information, as well as interviews with key staff from the operator. The whole set of surveys, interviews and ABC methodology puts together a comprehensive approach for analysis and research. Surveys and subsequent analysis shows service headway, punctuality and safety as the three most important service attributes from the user’s point of view. The proposed methodology has been applied to these three variables, as described in chapter 5. Results obtained in chapter 6 show the consistency and practicality of this methodology, overcoming simplifications from traditional accounting procedures. According to the latter, a calculation of costs based on mileage can overvalue quality improvements up to three times the results following ABC methodology. Finally, in chapter 7, the main conclusions are highlighted and some future research is suggested in terms of application improvements as well as results transferability.

A implementação do modelo activity-based costing numa instituição de ensino superior: o caso do Instituto Politécnico de Leiria

As instituições de ensino superior estão obrigadas pelo Plano Oficial de Contabilidade Pública para o sector da educação (POC-Educação) a adotar a integração da contabilidade orçamental com a contabilidade patrimonial e a contabilidade analítica. O facto de o POC-Educação referenciar a contabilidade analítica como um instrumento indispensável à gestão das organizações de ensino superior, na medida em que apoia os gestores no controlo das atividades desenvolvidas e no processo de tomada de decisões, associado à motivação obtida com a minha experiência profissional, integrado na Direção de Serviços Financeiros, de uma instituição de ensino superior, foi o ponto de partida para este projeto, subordinado ao tema “A implementação do modelo Activity-Based Costing numa instituição do ensino superior: o caso do Instituto Politécnico de Leiria” com o qual se pretende aferir a aplicabilidade dos princípios que sustentam o Activity-Based Costing (ABC) como instrumento de gestão numa instituição do ensino superior. Várias técnicas poderiam ser utilizadas para a concretização deste trabalho, no entanto quer pela contemporaneidade do conceito quer pelas características da instituição objeto de estudo foi decidido testar a metodologia ABC que apresenta benefícios na distribuição dos custos indiretos e comuns pelos objetos de custeio, face aos sistemas de custeio tradicionais. Considerando a dimensão do Instituto Politécnico de Leiria, e aproveitando os benefícios da sua estrutura organizacional, optamos por aplicar a metodologia apenas a parte da organização, no caso em concreto à Direção de Serviços Informáticos. Os resultados apresentados permitem concluir que os fundamentos que estão na base do modelo ABC podem ser aplicados a diversos serviços da instituição do ensino superior objeto de análise.

Apuramento de custos por utente nos cuidados de saúde primários

RESUMO - Introdução: A ausência de um plano de contabilidade analítica para os Cuidados de Saúde Primários é um problema para a realização da contabilidade interna, fundamental para a gestão de qualquer instituição de saúde. Sem linhas orientadoras para a uniformização dos critérios de imputação e distribuição dos custos/proveitos, torna-se complicado obter dados analíticos para que haja um controlo de gestão mais eficaz, que permita a utilização dos recursos de uma forma eficiente e racional, melhorando a qualidade da prestação de cuidados aos utentes. Objectivo: O presente projecto de investigação tem como principal objectivo apurar o custo por utente nos Cuidados de Saúde Primários. Metodologia: Foi construída uma metodologia de apuramento de custos com base no método Time-Driven Activity-Based Costing. O custo foi imputado a cada utente utilizando os seguintes costs drivers: tempo de realização da consulta e a produção realizada para a imputação dos custos com o pessoal médico; produção realizada para a imputação dos outros custos com o pessoal e dos custos indirectos variáveis; número total de utentes inscritos para a imputação dos custos indirectos fixos. Resultados: O custo total apurado foi 2.980.745,10€. O número médio de consultas é de 3,17 consultas por utente inscrito e de 4,72 consultas por utente utilizador. O custo médio por utente é de 195,76€. O custo médio por utente do género feminino é de 232,41€. O custo médio por utente do género masculino é de 154,80€. As rubricas com mais peso no custo total por utente são os medicamentos (40,32%), custo com pessoal médico (22,87%) e MCDT (17,18%). Conclusão: Na implementação de um sistema de apuramentos de custos por utente, é fulcral que existam sistemas de informação eficientes que permitam o registo dos cuidados prestados ao utente pelos vários níveis de prestação de cuidados. É importante também que a gestão não utilize apenas os resultados apurados como uma ferramenta de controlo de custos, devendo ser potenciada a sua utilização para a criação de valor ao utente.

Activity-based life cycle costing model for cost estimation and monitoring – Case: manned and autonomous dry bulk carrier

Recent developments in automation, robotics and artificial intelligence have given a push to a wider usage of these technologies in recent years, and nowadays, driverless transport systems are already state-of-the-art on certain legs of transportation. This has given a push for the maritime industry to join the advancement. The case organisation, AAWA initiative, is a joint industry-academia research consortium with the objective of developing readiness for the first commercial autonomous solutions, exploiting state-of-the-art autonomous and remote technology. The initiative develops both autonomous and remote operation technology for navigation, machinery, and all on-board operating systems. The aim of this study is to develop a model with which to estimate and forecast the operational costs, and thus enable comparisons between manned and autonomous cargo vessels. The building process of the model is also described and discussed. Furthermore, the model’s aim is to track and identify the critical success factors of the chosen ship design, and to enable monitoring and tracking of the incurred operational costs as the life cycle of the vessel progresses. The study adopts the constructive research approach, as the aim is to develop a construct to meet the needs of a case organisation. Data has been collected through discussions and meeting with consortium members and researchers, as well as through written and internal communications material. The model itself is built using activity-based life cycle costing, which enables both realistic cost estimation and forecasting, as well as the identification of critical success factors due to the process-orientation adopted from activity-based costing and the statistical nature of Monte Carlo simulation techniques. As the model was able to meet the multiple aims set for it, and the case organisation was satisfied with it, it could be argued that activity-based life cycle costing is the method with which to conduct cost estimation and forecasting in the case of autonomous cargo vessels. The model was able to perform the cost analysis and forecasting, as well as to trace the critical success factors. Later on, it also enabled, albeit hypothetically, monitoring and tracking of the incurred costs. By collecting costs this way, it was argued that the activity-based LCC model is able facilitate learning from and continuous improvement of the autonomous vessel. As with the building process of the model, an individual approach was chosen, while still using the implementation and model building steps presented in existing literature. This was due to two factors: the nature of the model and – perhaps even more importantly – the nature of the case organisation. Furthermore, the loosely organised network structure means that knowing the case organisation and its aims is of great importance when conducting a constructive research.

Desenvolvimento de um modelo integrado so Activity-Based Management (ABM) para análise de eficácia em serviços de emergência

A gestão assistencial, cada vez mais, assume a responsabilidade integral do desempenho dos serviços e/ou unidades hospitalares, passando a responder não somente pelo desempenho assistencial como também pelo econômico. Em conseqüência, há maior compreensão do processo e dos recursos consumidos. Assim, os indicadores assistenciais (tempo médio de permanência, taxas de infecção, taxas de óbito) passam a ser as causas mais óbvias e verdadeiramente afins para explicar e revestir os valores econômicos. Todavia, ela necessita de um modelo administrativo que a norteie, possibilitando assim, um gerenciamento sistematizado, científico e qualificado, que atinja as metas traçadas, refletidas nos indicadores de resultado da qualidade assistencial e econômica. Este trabalho teve como objetivo desenvolver um modelo integrado ao Activity-Based Management (ABM) para melhor analisar a eficácia em Serviços de Emergência, buscando através do mapeamento dos processos e custeio das principais atividades, propor o gerenciamento dos Protocolos Clínicos e das Intervenções Terapêuticas - Therapeutic lntervention Scoring System (TISS) pelo método ABM. O desenvolvimento do modelo deu-se em duas etapas: I°) Identificação dos principais serviços prestados e mapeamento dos processos e principais atividades do Plantão Médico do Hospital Mãe de Deus, Porto Alegre -RS; 2°) Desdobramento da análise de Eficiência e Eficácia através de um sistema de informações, onde as entradas consideradas foram os processos, subprocessos e atividades mapeadas e custeadas pelo método Activity- Based Costing (ABe); os processadores foram os protocolos clínicos (ABM estratégico), as rotinas, o TISS e a estatística descritiva (ABM operacional); resultando na saída do sistema a análise da Eficácia (qualidade, tempo e custo) gerando relatórios da Eficácia Assistencial. Considerando-se que na saúde, mesmo contando com a utilização dos melhores recursos e tempos hábeis, existe a probabilidade de desfechos insatisfatórios, o modelo assumiu que para análise da qualidade, a avaliação está embasada num todo, onde se somam basicamente o tempo ideal preconizado para cada situação e a expectativa da utilização otimizada dos recursos (mão-de-obra, materiais, medicamentos, exames e equipamentos). Para análise dos tempos, considerou-se as evidências da obtenção de melhores resultados clínicos. Assim sendo, toda vez que os tempos forem além do preconizado pelos protocolos e rotinas, haverá ineficácia no processo, pois os objetivos assistenciais dos desfechos clínicos serão perturbados. E por fim, na análise dos custos, foram considerados ao mesmo tempo o meio e o fim da quantificação de ociosidade ou desperdício e da qualidade assistencial respectivamente. Fazer as coisas que devem ser feitas, com qualidade a custo menor, proporciona perspectivas de eficácia ao encontro dos objetivos da organização. Como resultados, pode-se constatar que os protocolos clínicos e as intervenções pelo TISS integrados ao ABM e com o uso da estatística descritiva, muito embora não sejam fórmulas rígidas a serem seguidas, mostraram indiscutivelmente a eficácia e a eficiência do processos assistencial, respeitadas as variabilidades de condutas e utilização de recursos explicáveis pela diversidade das doenças.

The Implications of Activity Based Funding for Emergency Departments : A Comprehensive Literature Review

Executive Summary Emergency Departments (EDs) locally, nationally and internationally are becoming increasingly busy. Within this context, it can be challenging to deliver a health service that is safe, of high quality and cost-effective. Whilst various models are described within the literature that aim to measure ED ‘work’ or ‘activity’, they are often not linked to a measure of costs to provide such activity. It is important for hospital and ED managers to understand and apply this link so that optimal staffing and financial resourcing can be justifiably sought. This research is timely given that Australia has moved towards a national Activity Based Funding (ABF) model for ED activity. ABF is believed to increase transparency of care and fairness (i.e. equal work receives equal pay). ABF involves a person-, performance- or activity-based payment system, and thus a move away from historical “block payment” models that do not incentivise efficiency and quality. The aim of the Statewide Workforce and Activity-Based Funding Modelling Project in Queensland Emergency Departments (SWAMPED) is to identify and describe best practice Emergency Department (ED) workforce models within the current context of ED funding that operates under an ABF model. The study is comprised of five distinct phases. This monograph (Phase 1) comprises a systematic review of the literature that was completed in June 2013. The remaining phases include a detailed survey of Queensland hospital EDs’ resource levels, activity and operational models of care, development of new resource models, development of a user-friendly modelling interface for ED mangers, and production of a final report that identifies policy implications. The anticipated deliverable outcome of this research is the development of an ABF based Emergency Workforce Modelling Tool that will enable ED managers to profile both their workforce and operational models of care. Additionally, the tool will assist with the ability to more accurately inform adequate staffing numbers required in the future, inform planning of expected expenditures and be used for standardisation and benchmarking across similar EDs. Summary of the Findings Within the remit of this review of the literature, the main findings include: 1. EDs are becoming busier and more congested Rising demand, barriers to ED throughput and transitions of care all contribute to ED congestion. In addition requests by organisational managers and the community require continued broadening of the scope of services required of the ED and further increases in demand. As the population live longer with more lifestyle diseases their propensity to require ED care continues to grow. 2. Various models of care within EDs exist Models often vary to account for site specific characteritics to suit staffing profile, ED geographical location (e.g. metropolitan or rural site), and patient demographic profile (e.g. paediatrics, older persons, ethnicity). Existing and new models implemented within EDs often depend on the target outcome requiring change. Generally this is focussed on addressing issues at the input, throughput or output areas of the ED. Even with models targeting similar demographic or illness, the structure and process elements underpinning the model can vary, which can impact on outcomes and variance to the patient and carer experience between and within EDs. Major models of care to manage throughput inefficiencies include: A. Workforce Models of Care focus on the appropriate level of staffing for a given workload to provide prompt, timely and clinically effective patient care within an emergency care setting. The studies reviewed suggest that the early involvement of senior medical decision maker and/or specialised nursing roles such as Emergency Nurse Practitioners and Clinical Initiatives Nurse, primary contact or extended scope Allied Health Practitioners can facilitate patient flow and improve key indicators such as length of stay and reducing the number of those who did not wait to be seen amongst others. B. Operational Models of Care within EDs focus on mechanisms for streaming (e.g. fast-tracking) or otherwise grouping patient care based on acuity and complexity to assist with minimising any throughput inefficiencies. While studies support the positive impact of these models in general, it appears that they are most effective when they are adequately resourced. 3. Various methods of measuring ED activity exist Measuring ED activity requires careful consideration of models of care and staffing profile. Measuring activity requires the ability to account for factors including: patient census, acuity, LOS, intensity of intervention, department skill-mix plus an adjustment for non-patient care time. 4. Gaps in the literature Continued ED growth calls for new and innovative care delivery models that are safe, clinically effective and cost effective. New roles and stand-alone service delivery models are often evaluated in isolation without considering the global and economic impact on staffing profiles. Whilst various models of accounting for and measuring health care activity exist, costing studies and cost effectiveness studies are lacking for EDs making accurate and reliable assessments of care models difficult. There is a necessity to further understand, refine and account for measures of ED complexity that define a workload upon which resources and appropriate staffing determinations can be made into the future. There is also a need for continued monitoring and comprehensive evaluation of newly implemented workforce modelling tools. This research acknowledges those gaps and aims to: • Undertake a comprehensive and integrated whole of department workforce profiling exercise relative to resources in the context of ABF. • Inform workforce requirements based on traditional quantitative markers (e.g. volume and acuity) combined with qualitative elements of ED models of care; • Develop a comprehensive and validated workforce calculation tool that can be used to better inform or at least guide workforce requirements in a more transparent manner.

VisArchive: a time and relevance based visual interface for searching, browsing, and exploring project archives

Background Project archives are becoming increasingly large and complex. On construction projects in particular, the increasing amount of information and the increasing complexity of its structure make searching and exploring information in the project archive challenging and time-consuming. Methods This research investigates a query-driven approach that represents new forms of contextual information to help users understand the set of documents resulting from queries of construction project archives. Specifically, this research extends query-driven interface research by representing three types of contextual information: (1) the temporal context is represented in the form of a timeline to show when each document was created; (2) the search-relevance context shows exactly which of the entered keywords matched each document; and (3) the usage context shows which project participants have accessed or modified a file. Results We implemented and tested these ideas within a prototype query-driven interface we call VisArchive. VisArchive employs a combination of multi-scale and multi-dimensional timelines, color-coded stacked bar charts, additional supporting visual cues and filters to support searching and exploring historical project archives. The timeline-based interface integrates three interactive timelines as focus + context visualizations. Conclusions The feasibility of using these visual design principles is tested in two types of project archives: searching construction project archives of an educational building project and tracking of software defects in the Mozilla Thunderbird project. These case studies demonstrate the applicability, usefulness and generality of the design principles implemented.

Leisure-time physical activity, health related functioning and retirement : a prospective cohort study among middle-aged employees

Physical inactivity has become a major threat to public health worldwide. The Finnish health and welfare policies emphasize that the working population should maintain good health and functioning until their normal retirement age and remain in good health and independence later in life. Health behaviours like physical activity potentially play an important role in reaching this target as physical activity contributes to better physical fitness and to reduced risk of major chronic diseases. The aim of this study was to examine first whether the volume and intensity of leisure-time physical activity impacts on subsequent physical health functioning, sickness absence and disability retirement. The second aim was to examine changes in leisure-time physical activity of moderate and vigorous intensity after transition to retirement. This study is part of the ongoing Helsinki Health Study. The baseline data were collected by questionnaires in 2000 - 02 among the employees of the City of Helsinki aged 40 to 60. The follow-up survey data were collected in 2007. Data on sickness absence were obtained from the employer s (City of Helsinki) sickness absence registers and pension data were obtained from the Finnish Centre for Pensions. Leisure-time physical activity was measured in four grades of intensity and classified according to physical activity recommendations considering both the volume and intensity of physical activity. Statistical techniques including analysis of covariance, logistic regression, Cox proportional hazards models and Poisson regression were used. Employees who were vigorously active during leisure time especially had better physical health functioning than those physically inactive. High physical activity in particular contributed to the maintenance of good physical health functioning. High physical activity also reduced the risk of subsequent sickness absences as well as the risk of all-cause disability retirement and retirement due to musculoskeletal and mental causes. Among those transferred to old-age retirement moderate-intensity leisure-time physical activity increased on average by more than half an hour per week and in addition the occurrence of physical inactivity reduced. Such changes were not observed among those remained employed and those transferred to disability retirement. This prospective cohort study provided novel results on the effects of leisure-time physical activity on health related functioning and changes in leisure-time physical activity after retirement. Although the benefits of moderate-intensity physical activity for health are well known these results suggest the importance of vigorous physical activity for subsequent health related functioning. Thus vigorous physical activity to enhance fitness should be given more emphasis from a public health perspective. In addition, physical activity should be encouraged among those who are about to retire.

Physiological modelling for improved reliability in silhouette-driven gradient-based hand tracking

We present a gradient-based motion capture system that robustly tracks a human hand, based on abstracted visual information - silhouettes. Despite the ambiguity in the visual data and despite the vulnerability of gradient-based methods in the face of such ambiguity, we minimise problems related to misfit by using a model of the hand's physiology, which is entirely non-visual, subject-invariant, and assumed to be known a priori. By modelling seven distinct aspects of the hand's physiology we derive prior densities which are incorporated into the tracking system within a Bayesian framework. We demonstrate how the posterior is formed, and how our formulation leads to the extraction of the maximum a posteriori estimate using a gradient-based search. Our results demonstrate an enormous improvement in tracking precision and reliability, while also achieving near real-time performance. © 2009 IEEE.
