Estuda a problema do dimensionamento de lote em sistemas de produção intermitente, considerando os diferentes estágios do fluxo de materiais em uma empresa incluindo compra, produção e distribuição. Apresenta diversos modelos de mínimo custo, baseados em pressupostos faz como: operação em condições ideais (modelo clássico); existência ou não de descontos de compra; abastecimento instantâneo ou contínuo; existência ou não de restrições na disponibilidade de recursos; demanda determinística ou probabilística; existência ou não de permissão de faltas; itens isolados, itens múltiplos ou agregados de itens; estágio início ou estágios múltiplos; etc.

Gestão de estoques: uma proposta de reposição contínua para material médico hospitalar e medicamentos em um hospital universitário federal do estado do Rio Grande do Norte

The inventory management in hospitals is of paramount importance, since the supply materials and drugs interruption can cause irreparable damage to human lives while excess inventories involves immobilization of capital. Hospitals should use techniques of inventory management to perform replenishment in shorter and shorter intervals, in order to reduce inventories and fixed assets and meet citizens requirements properly. The inventory management can be an even bigger problem for public hospitals, which have restrictions on the use of resources and decisionmaking structure more bureaucratized. Currently the University Hospital Onofre Lopes (HUOL) uses a periodic replacement policy for hospital medical supplies and medicines, which involves one moment surplus stock replenishment, the next out of stock items. This study aims to propose a system for continuous replenishment through order point for inventory of medical supplies and medicines to the hospital HUOL. Therefore, a literature review of Federal University Hospitals Management, Logistics, Inventory Management and Replenishment System in Hospitals was performed, emphasizing the demand forecast, classification or ABC curve and order point system. And also, policies of inventory management and the current proposal were described, dealing with profile of the mentioned institution, the current policy of inventory management and simulation for continuous replenishment order point. For the simulation, the sample consisted of 102 and 44 items of medical and hospital drugs, respectively, selected using the ABC classification of inventory, prioritizing items of Class A, which contains the most relevant items in added value, representing 80 % of the financial value in 2012 fiscal year. Considering that it is a public organization, subject to the laws, we performed two simulations: the first, following the signs for inventory management of Instruction No. 205 (IN 205 ), from Secretary of Public Administration of the Presidency ( SEDAP / PR ), and the second, based on the literature specializing in inventory management hospital. The results of two simulations were compared to the current policy of replenishment system. Among these results are: an indication that the system for continuous replenishment reorder point based on IN 205 provides lower levels of safety stock and maximum stock, enables a 17% reduction in the amount spent for the full replenishment of inventories, in other words, decreasing capital assets, as well as reduction in stock quantity, also the simulation made from the literature has indicated parameters that prevent the application of this technique to all items of the sample. Hence, a change in inventory management of HUOL, with the application of the continuous replenishment according to IN 205, provides a significant reduction in acquisition costs of medical and hospital medicine

Análise doprojeto de expansãode um armazém por meio da elaboração de um layout e análise de investimento: estudo de caso em uma fábrica do setor alimentício

The proper management of materials storage is essential to supply the needs of production and reduce the inventory costs. Moreover, an effective layout contributes to improve the productivity and reduce the operational costs of a warehouse. This way, the purpose of this study was: to propose an expansion project to the warehouse of a factory in the food sector, suggesting a layout that best fit their needs and to verify its economic feasibility. To achieve this goal, it was applied methods such as ABC curve, spaghetti diagram and concepts of economics engineering to the analysis of investment in the project. The results showed that the second layout model was better than the first, supporting the storage capacity required by the company and presenting an internal movement more efficient. However, with the investment analysis, it was found that it was not feasible, given the conditions of the company, investing in the expansion of the warehouse

Displays also a calculation for the minimum value of stock and replacement of an item in inventory and an analysis of the conditions of the warehouse layout. As a result, knowledge is acquired and a revised system of inventory management of the institution was proposed

Proposta de melhoria do layout de um armazém de vidros automotivos

This work was based on a case study of improvement of the warehouse layout of a multinational automotive glass sector, located in the State of Sao Paulo. The aim was to propose a layout template to be more effective and besides optimizing production would also promote an increase in warehouse packaging capacity for metal containers containing glasses, thus reducing operating costs. To achieve the desired purpose, it was developed two layout proposals and to this end inventory management tools have been used, such as ABC curve and the Spaghetti Diagram, and other concepts of Packaging Engineering and Logistics. By the end of this work, it was obtained as a result, a project in which it was possible to rearrange the packages according the demand, and the developed changes became the most efficient layout both in storage capacity as well as in the internal drive

Comportamiento biológico y farmacocinético de dos formulaciones comerciales de ivermectina 3,15% en bovinos

Resumen Se realizó una prueba de establo para evaluar la eficacia residual de ivermectina 3,15% y los niveles plasmáticos en animales tratados con Ivomec GOLD® y con una formulación genérica frente a desafíos larvarios de Rhipicephalus (B.) microplus. En ambas formulaciones la eficacia residual presentó una gran dispersión en los días sin caída de garrapatas teleoginas post tratamiento. Descontando el ciclo parasitario la residualidad se presentó en un rango de 35 a 63 días. El análisis estadístico de los resultados de ambas formulaciones estudiadas a través de la mediana, demostró una residualidad de 52 días frente a larvas infestantes de R. (B) microplus. Los parámetros farmacocinéticos presentaron valores medios de: área bajo la curva (ABC) 1795±188 y 1351±118, picos plasmáticos (Tmax) a los 13,4±4,1 y 15,0±3,6 días post inoculación con concentración máxima (Cmax) de 65,4±1,5 y 41,1±0,3 ppb para la formulación de Ivomec GOLD® y la genérica respectivamente. Concentraciones inferiores a 10 ppb pueden representar el umbral por debajo del cual se logró desarrollar el ciclo parasitario hasta obtener garrapatas teleoginas. Los resultados obtenidos permitirán tener un mejor conocimiento para evaluar el comportamiento de las formulaciones en pruebas de establo y de campo tanto en el estudio de la eficacia, la residualidad y en el tiempo de espera para la faena.

Evolução do sistema de custos baseados em atividades: um estudo exploratório da utilização da metodologia de ABC ao longo do tempo

Muito tem se escrito desde o surgimento da Metodologia de Custeio Baseado em AtividadesABC como técnica alternativa aos modelos contábeis de custeio. A seu respeito diversos autores buscaram exaltar suas vantagens, sugeriram aplicações variadas, inclusive em apoio a outras ferramentas de gestão e revelaram segredos para realizar implantar essa técnica com sucesso. Visto que são passados mais de 10 anos de implantações dessa técnica em diversas empresas no Brasil e considerando-se a existência de uma curva de aprendizagem em relação ao uso e aplicações da metodologia, muito pouco se falou sobre o que aconteceu depois de uma implantação de sucesso. O que houve depois que os primeiros resultados apareceram, depois que as informações de custos se incorporaram no dia-a-dia das empresas, o que se criou a partir do uso da metodologia? A proposta desse trabalho é portanto explorar a realidade das empresas que implementaram o ABC e ver como a técnica evoluiu. Assim busca-se responder a questões como quais aplicações são realmente colocadas em prática e que tipo de lições os usuários com mais de três anos de uso aprenderam no dia-a-dia. As respostas encontradas passaram pela definição e classificação de sete diferentes categorias para as aplicações sugeridas para a metodologia. Posteriormente, através dos dados da pesquisa de campo foi possível a identificação daquelas categorias com maior grau de utilização. Os dados da pesquisa também revelaram as tendências no uso da metodologia e confirmaram a existência de um processo de amadurecimento no uso da metodologia, bem como as variáveis influentes nesse processo.

The key lessons learnt from producing the ABC programme Talking Heads a talk show/documentary hybrid in a fast turnaround environment

The following exegesis will detail the key advantages and disadvantages of combining a traditional talk show genre with a linear documentary format using a small production team and a limited budget in a fast turnaround weekly environment. It will deal with the Australian Broadcasting Corporation series Talking Heads, broadcast weekly in the early evening schedule for the network at 18.30 with the presenter Peter Thompson. As Executive Producer for the programme at its inception I was responsible for setting it up for the ABC in Brisbane, a role that included selecting most of the team to work on the series and commissioning the music, titles and all other aspects required to bring the show to the screen. What emerged when producing this generic hybrid will be examined at length, including: „h The talk show/documentary hybrid format needs longer than 26¡¦30¡¨ to be entirely successful. „h The type of presenter ideally suited to the talk show/documentary format requires someone who is genuinely interested in their guests and flexible enough to maintain the format against tangential odds. „h The use of illustrative footage shot in a documentary style narrative improves the talk show format. iv „h The fast turnaround of the talk show/documentary hybrid puts tremendous pressure on the time frames for archive research and copyright clearance and therefore needs to be well-resourced. „h In a fast turnaround talk show/documentary format the field components are advantageous but require very low shooting ratios to be sustainable. „h An intimate set works best for a talk show hybrid like this. Also submitted are two DVDs of recordings of programmes I produced and directed from the first and third series. These are for consideration in the practical component of this project and reflect the changes that I made to the series.

Measuring the success of ABC training in South Africa: A case study in the production of Western Liberal broadcast news values

In 1993 the Australian Broadcasting Corporation was contracted by the Australian Government to assist in the reshaping of the South African Broadcasting Corporation from a state-run broadcaster to a respected and trusted national broadcaster for all people in the newly democratic South Africa. Broadcast journalism training was identified by ABC consultant Bob Wurth as possibly the greatest need for SABC Radio. This thesis examines the ABC's role in South Africa and the effectiveness of its radio journalism training project considering the organisational, structural, cultural and political constraints of the SABC. This thesis will show through interviews and participant observation the difficulties in achieving the production of Western Liberal journalism values at the SABC within the time constraints set by the project funded by the Australian Government and the particular South African morays.

Public service broadcasting, creative industries and innovation infrastructure : the case of ABC's Pool

The proliferation of media services enabled by digital technologies poses a serious challenge to public service broadcasting rationales based on media scarcity. Looking to the past and future, we articulate an important role that the Australian Broadcasting Corporation (ABC) might play in the digital age. We argue that historically the ABC has acted beyond its institutional broadcasting remit to facilitate cultural development and, drawing on the example of Pool (an online community of creative practitioners established and maintained by the ABC), point to a key role it might play in fostering network innovation in what are now conceptualised as the creative industries.

Simple as ABC? An examination of Activity Based Costing (ABC) Implementation in Fiji

We review the level of Activity Based Costing (ABC) in Fiji in this article. This exercise is important in furthering our understanding of the use of ABC in Fiji. ABC is a popular costing system and strategic tool for organizations in developed countries (Chenhall and Langfield-Smith 1998). However, little is known about the benefits and challenges of implementing ABC in developing countries. Such an understanding could stimulate discussion on the development or modification of ABC to suit developing country circumstances. The article also has a practical objective in informing and education organizations in Fiji regarding the benefits and challenges of ABC implementation in Fiji and also provides practical suggestions for improving and easing the implementation of ABC.

Extending the ABC's public service remit through ABC Pool

Historically, the public service broadcaster (PSB) acted beyond its institutional broadcasting remit by initiating and facilitating activities to support cultural infrastructure and national identity (Wilson, Hutchinson and Shea 2010). The recent focus to develop new content delivery platforms and services (Debrett 2010) signifies a semantic shift from the PSB to the public service media (PSM) organisation. The Australian PSM organisation, the Australian Broadcasting Corporation (ABC) has moved beyond the era of ‘online’ publishing to incorporate Web 2.0 technologies to foster new relationships with the audience (Walker 2009) and engage in production activities with participatory cultures (Jenkins 2006). This shift presents opportunities and challenges to traditional media production, the existing editorial policies and governance models, and raises questions around the value of PSM experimental and innovative activities. Further, the incorporation of information communication technologies and participatory cultures challenge the core values of ‘public service’ within PSM. This paper examines ABC Pool (abc.net.au/pool) as a means of extending the ABC’s public service remit by incorporating participatory cultures into the production and governance models of the corporation and critically analyses the public value of such innovative experiments.

Importing Wikipedia principles into the cultural institution of a public service broadcaster : the case of ABC Pool

Web 2.0 technologies have mobilised collaborative peer production and participatory cultures for online content creation. However, not all online communities engaging in these activities are independently facilitated and often operate within the auspices of the cultural institutions that develop and resource them. Borrowing from the principles of Wikipedia that supports collaborative online content creation and online community, ABC Pool (abc.net.au/pool) is one such institutional online community operating with the support of the Australian Public Service Broadcaster (PSB), the Australian Broadcasting Corporation (ABC). This paper explores the collaborative, creative, and governance activities of an institutional online community and how the role of the community manager is an intermediary within these arrangements.

The cultural impact of institutional remix : the formalisation of textual reappropriation within the ABC

In 2009, Mark Deuze proposed an updated approach to media studies to incorporate ‘media life’, a concept he suggests addresses the invisibleness of ubiquitous media. Media life provides a useful lens for researchers to understand the human condition in media and not with media. At a similar time, public service media (PSM) strategies have aligned audience participation with the so‐called Reithian trinity which suggest the PSB should inform, educate and entertain while performing its core values of public service broadcasting (Enli 2008). Remix within the PSM institution relies on audience participation, employing ‘the people formerly known as the audience’ (Rosen 2006) as cultural artifact producers, and draws on their experience from within the media. Remix as a practice then enables us to examine the shift of the core PSM values by understanding how audience participation, informed by a human condition mobilised from our existence of being in media and not merely with media. However, remix within PSM challenges the once elitist construction of meaning models with an egalitarian approach towards socially reappropriated texts, questioning its affect on the cultural landscape. This paper draws on three years of ethnographic data from within the Australian Broadcasting Corporation (ABC), exploring the remix culture of ABC Pool. ABC Pool operates under a Creative Commons licensing regime to enable remix practice under the auspices of the ABC. ABC Pool users provide a useful group of remix practitioners to examine as they had access to a vast ABC archival collection and were invited to remix those cultural artefacts, often adding cultural and fiscal value. This paper maintains a focus on the audience participation within PSM through remix culture by applying media dependency theory to remix as cultural practice and calls to expand and update the societal representation within the ABC.
