Intermediate storage system optimization is an essential aspect which this report tends to look upon and putting effort on improving operating efficiency then reducing the capital cost of batch/ semi-continuous or flow production process by looking at the extent of estimating the figures of boxes that are made to be in the intermediate storage system through evaluations. Additionally, intermediate storage can reduce the effects of process parameter variations, such as recipe inaccuracies and operator errors, in which process operations are particularly visible. In a channel of operations, where there are many amount of shift that are inevitable to pass through in order to complete production process to get a finished product. Hence, longer operating horizon, process variations must include a measurable parameter, either shorter or longer to avoid failure of meeting product specification and limitation of meeting end users specification. Intermediate storage system as a back-up function in case of some sudden failure within the production line In this thesis, it is notable to make an amendment, as a way of knowing the accuracy of boxes of bearing work-piece that will be maintaining a certain intermediate storage system to feed the next shift of workstation in a continuous process with accurate or known estimated number of work-piece in a role, until the final product is been made. Hence, in this research, there are many theory that were adopted to give a clear view of what will be obtainable in the whole research both in empirical finding to have a definite result. To achieve the above goal this thesis followed a steps to fulfil its objective. Steps 1 and 2 were to know the strategic plans as well as operating methods through theory also, to know the production line balancing to have a view of time measured through the theory. Step 3 and 4 adoptions of theory and empirical finding to calculate, productivity through the source of cycle time, as well as facility plan and to give analysis of intermediate storage system, in optimization of production line to make a work flow achievable at the end, to meet the customers demand.

Det traditionella perspektivet i hälso- och sjukvården behöver förändras, från en levererad produkt till co-production mellan sjukvårdspersonal och patienter. Patienter som drabbas av en höftfraktur lider vanligen av hög smärta och innan transport till sjukhus krävs bedömning och smärtlindring av ambulanspersonal. Lokalt inom ambulanssjukvård är det däremot inte utvärderat om patienten är involverad i bedömning och behandling enligt co-production. Motsvarande är inte heller kvaliteten av den medicinska riktlinjen för höftfrakturer systematiskt utvärderad lokalt. Målet med detta förbättringsarbete var att mäta och öka journalförda smärtskattningar samt att möjliggöra en reviderad version av den medicinska riktlinjen med ökad kvalitet. Förbättringsåtgärder skapades utifrån hörnstensmodellen. En kvalitativ studie undersökte personalens uppfattningar av förbättringsarbetet för co-production i vården. Intervjuer med personal i fokusgrupper analyserades med en deskriptiv ansats och med ramverket co-production cycle. Resultatet visar på en signifikant ökning av journalförd smärtskattning och en ökad kvalitet av den medicinska riktlinjen. Studien visar på en motivation att fråga, snarare än att anta nivån av patienternas smärta. Slutsatsen är att det är möjligt att mäta medicinska riktlinjers kvalitet och därmed deras förbättring. Genom att visualisera det journalförda vårdarbetet, jämlikt hörnstensmodellen, skapas en motivation till förändring gentemot co-production i vården. / The traditional perspective of healthcare needs transformation, from a delivered product to a co-produced service between healthcare professionals and patients. When a patient sustains a hip fracture it is often characterized with severe pain and requires an ambulance for assessment and pain relief before transportation to a hospital. However, in context of the ambulance service it is not evaluated if the patient is involved and co-produces in the assessment and treatment. Neither is the quality of the medical guideline for treatment of hip fracture systematically evaluated in the local context. The aim of this improvement work was to measure and increase the documented pain assessment, as well to measure the quality of the medical guideline so it can be revised with an improved quality. Interventions was formed using the cornerstone model as a framework. A qualitative study was performed to analyse effects of the improvement work experienced by the personnel for co-producing care with patients. Focus groups interviews with the personnel was conducted using a descriptive approach and the co-production cycle as framework. The results show a significant increase in the documentation of the pain assessments and an increased quality in the medical guideline. The study shows a motivation to ask, rather than assume patient’s pain assessment. In conclusion it is possible to measure the quality of a medical guideline and therefore so is improvement. Visualising documented care to the personnel in accordance with the cornerstone model, creates a motivation for change towards co-producing care.

One of the objectives of disaggregation in hierarchical production planning is to minimize the setup costs incurred when changing production from one family to another. In this research, the setup costs are reduced by determining a production schedule that minimizes the number of setups during the planning horizon. Previous solutions to the disaggregation problem have considered discrete-time, and more recently continuous-time formulations. This research extends the continuous time disaggregation approach by incorporating production schedules allowing backorder. A mathematical formulation and a solution algorithm are presented and the computational complexity and convergence properties of the algorithm are discussed. Experimental results, using both deterministic and stochastic demand patterns, which demonstrate the efficacies of the solution approach are provided.

The first experiment was performed at the end of the first production cycle, in the period from 50 a 66 weeks of age and the second with birds in the period from 74 to 90 weeks of age. In both experiments, 150 layers Shaver Brow laying hens, distributed in a completely randomized design, with five treatments (digestible lysine levels: 0.79, 0.82, 0.85, 0.8 and 0.91%), six replications and five birds for experimental unit. The experimental period lasted 16 weeks and it was divided in four periods of collection of the eggs, being each one corresponding to 28 days. The parameters evaluates were the productive performance (production, mass and egg´ weight), of the intake consumption (feed and lysine), of the feed conversion (mass and egg dozen), egg components (albumen, yolk and shell), of the egg quality (albumen and yolk index, Haugh units and egg shell specific quality). In the first experiment, the productive performance, the feed intake, the feeds conversions, the components percentage, egg quality and yolk index were not influenced (P>0.05) by the levels of digestible lysine, except for the lysine intake which show a linear response (P<0.05) with increase in the digestible lysine levels. For the albumen index and Haugh units, the LRP model (Linear Response Plateau) adjusted better to the data, estimating at 0.832% and 0.883 % of the lysine digestible, respectively. In the second experiment, was observed a linear increase (P<0.05) of lysine intake increased as the level of dietary lysine and quadratic effect (P<0.05) of the yolk percentages, estimating the level of 0,837% digestible lysine for the lowest percentage of yolk. Variables such as performance, consumption, feed conversion, components percents and egg quality had not shown significant differences (P>0.05). Based on productive parameters that were not influenced by levels of lysine diets in both experiments, suggested the level of 0.79% of lysine, for brow-egg laying hens in the period from 50 to 66 weeks and 74 to 90 weeks of age / Foram conduzidos dois experimentos com o objetivo de determinar a exigência nutricional de lisina digestível para poedeiras semipesadas. O primeiro experimento foi realizado ao final do primeiro ciclo de produção, no período de 50 a 66 semanas de idade e o segundo com aves no período de 74 a 90 semanas de idade. Em ambos os experimentos, foram utilizadas 150 poedeiras semipesadas da linhagem Shaver Brow, distribuídas em um delineamento inteiramente casualizado (DIC) contendo cinco tratamentos (níveis de lisina digestível: 0,79; 0,82; 0,85; 0,88 e 0,91%), seis repetições e cinco aves por unidade experimental. Cada período experimental teve duração de 16 semanas, subdividido em quatro períodos de coleta dos ovos, sendo cada um correspondente a 28 dias. Foram avaliados os parâmetros de desempenho (produção, peso e massa de ovos), de consumo (ração e lisina), de conversão alimentar (dúzia e massa de ovos), de componentes dos ovos (porcentagem de gema, de casca e de albúmen) e de qualidade interna e externa dos ovos (índice de gema e de albúmen, unidade Haugh e gravidade específica). No primeiro experimento, o consumo de ração, as conversões alimentares, os percentuais dos componentes, a qualidade externa e o índice de gema dos ovos não foram influenciados (P>0,05) pelos níveis de lisina digestível, com exceção para consumo de lisina que aumentou linearmente (P<0,05) conforme aumentou o nível deste aminoácido na ração. Para o índice de albúmen e unidade Haugh, o modelo LRP (Linear Response Plateau) melhor se ajustou aos dados, estimando em 0,832% e 0,883% de lisina digestível, respectivamente. No segundo experimento, observou-se aumento linear (P<0,05) sobre o consumo de lisina conforme aumentou o nível deste aminoácido na ração e efeito quadrático (P<0,05) sobre a porcentagem de gema, estimando-se o nível de 0,837% de lisina digestível para menor valor desta variável. Os parâmetros de desempenho, consumo, conversão alimentar, porcentagens dos componentes, qualidade interna e externa não apresentaram diferenças significativas (P>0,05). Com base nos parâmetros produtivos que não foram influenciados pelos níveis de lisina das rações em ambos os experimentos é sugerido o nível de 0,79% de lisina digestível, para poedeiras semipesadas nos períodos de 50 a 66 semanas e de 74 a 90 semanas de idade

The constant needs for the reduction of companies operational costs has transformed Inventory into a targeted source for this end by upper management. The high investment value that it represents for organizations, aside from the immediate contribution to cash flow, when it is reduced, allows inventory to be a source of strategic advantage. The objective of this study is to understand the behavior of independent variables such as production cycletime or lead-time, daily demand rate of finished product and the interval between production orders and their effects on the determination of an inventory policy. The study is performed in a manufacturing company that produces intermittent, repetitive small batches and a large variety of products. Cash flow techniques are applied to detail the production processes and respective planning. The historical data of mentioned variables refer to the period from January 2000 to February 2002. These data are used to develop the calculations of safety stock and average and maximum stock from the viewpoint of the management approach in Replenishment Point and Periodically Review. The real application of the data available from the company is studied to calculate the inventory policy. It is concluded that, in spite of the adoption of a sophisticated mechanism of production planning and a strong culture of measurements by the company, the statistical data of fundamental variables are not utilized systematically to determine the inventory policy. This fact confirms the thesis that inventory reductions, in general, are circumstantial and is not supported by fundamental techniques. / A constante necessidade de redução dos custos operacionais das empresas tem transformado o Inventário em fonte preferencial, para este fim, pela alta administração. O alto valor de investimento que ele representa para as organizações, além da contribuição imediata no fluxo de caixa, quando da sua redução, faz com que o inventário seja uma fonte de vantagem competitiva.O objetivo deste estudo é compreender o comportamento das variáveis independentes como tempo de ciclo da produção ou lead-time, taxa diária de demanda do item de produto acabado e tempo de intervalo entre ordens de produção, e os seus efeitos no cálculo de uma política de inventário.O estudo é realizado em uma empresa de manufatura de produção intermitente repetitiva em lotes de pequenas quantidades e grande variedade de produtos.Técnicas de fluxo de valor são aplicadas para detalhamento dos processos de produção e do seu respectivo planejamento. Os dados históricos das variáveis mencionadas referem-se ao período de janeiro de 2000 a fevereiro de 2002. Com estes dados, desenvolvem-se os cálculos de estoque de segurança, estoque médio e máximo,sob a óptica das abordagens de gerenciamento por Ponto de Reposição e Revisão Periódica. Analisa-se a real aplicação dos dados disponíveis na empresa, para o cálculo da política de inventário. Conclui-se que apesar de ser adotado mecanismo sofisticado de planejamento de produção e haver uma forte cultura de medições por parte da empresa, os dados estatísticos das variáveis fundamentais não são utilizados de forma sistemática para o cálculo da política de inventário. Este fato confirma a tese de que as reduções de inventário, de uma maneira geral, são circunstanciais e não sustentadas por fundamentos técnicos.
