Produktionsstrategi för Heavy Factory : En effektiv produktionsmix som genererar 20 000 produktionstimmar / Production strategy for Heavy Factory : An efficient mix of production that generates 20 000 production hoursLarsen, Andreas January 2016 (has links)
Syftet med detta arbete har varit att ta fram förslag på hur utnyttjandegraden för de maskiner som används till bearbetning av Yankee-detaljer kan höjas, där arbetet har utförts på avdelningen för produktionsutveckling på Valmet AB i Karlstad. Målet med arbetet har varit att identifiera en eller flera produkter av de som idag produceras för externa kunder som skulle vara lämplig att produktionssätta för bearbetning i maskinverkstaden för tillverkning av Yankee-cylindrar. Målet har också varit att presentera en effektiv produktionsmix i maskinverkstaden som med den utvalda produkten genererar 20 000 produktionstimmar i de viktigaste maskinerna. Arbetet genomfördes med en kvalitativ ansats där intervjuer, observationer och litteraturstudier användes för att samla in data. Sekundärdata samlades in från olika databaser på Valmet. Tidigt skapades en projektplan som gav struktur till arbetet och en uppföljning av arbetet ägde rum med pulsmöten veckovis på Valmet. En utredning genomfördes över lämpliga produkter att produktionssätta för bearbetning. Efter val av produkt analyserades olika scenarier för att bestämma en produktionsmix som så effektivt som möjligt genererar 20 000 produktionstimmar. Den framtagna produktionsmixen visade sig generera en del problem vad gäller tillgängliga resurser, PIA, flödet och tillgänglig yta i maskinverkstaden. Med hjälp av Lean-filosofin har sju åtgärder tagits fram som ska leda till att en effektiv produktionsmix uppnås. Införandet av åtgärderna har delats in i tre steg där steg ett (1) anses som nödvändigt att införa för att kunna uppnå produktionsmixen medan steg två och tre är viktiga för flödeseffektiviteten och därmed för att kunna uppnå en effektiv produktionsmix. Resultatet av arbetet visar på att utnyttjandegraden av de viktigaste maskinerna i maskinverkstaden kan höjas genom en produktionssättning för bearbetning av produkten V164. Eftersom produkten tillverkas för vindkraftindustrin kan en produktionssättning för bearbetning även innebära en mindre känslighet för svängningar på marknaden för mjukpappersmaskiner och därmed generera en jämnare arbetsbelastning. / The aim of this work has been to develop proposals on how the utilization rate of the machines used for the processing of Yankee details can be increased. The work has been carried out at the Department of Production engineering at Valmet AB in Karlstad. The objective of the work was to identify one or more products, currently produced for external customers, which are suitable for a production launch for processing in the machine shop for manufacturing of Yankee cylinders. The objective has also been to present an efficient mix of production in the machine shop that with the selected product generates 20,000 production hours in the main machines. The work was carried out with a qualitative approach where interviews, observations and literature reviews were used to collect data. Secondary data were collected from different databases at Valmet. An early created project plan gave structure to the work and follow-up work took place with pulse meetings weekly at Valmet. An investigation was conducted of suitable products for a production launch for processing. After selecting the product various scenarios was analyzed to determine a mix of production that most efficient generate 20,000 production hours. The designed production mix appeared to generate some problems in terms of available resources, WIP, flow and available space in the machine shop. With the help of the Lean philosophy seven measures has been developed that will lead to an efficient mix of production is achieved. The introduction of measures has been divided into three steps. Step one (1) is considered necessary to impose in order to achieve the production mix, while step two and three are important for flow efficiency and thereby to achieve an efficient mix of production. The results of the work show that the utilization rate of the most important machines in the machine shop can be raised through a production launch for processing of the product V164. Thus the product is manufactured for the wind power industry, a production launch for processing also mean less sensitivity to fluctuations in the market for tissue paper machines and thereby a more even workload can be generated.

Large System Transformation within Healthcare Organizations utilizing Lean Deployment StrategiesHagg, Heather 11 December 2013 (has links)
"Multiple U.S. healthcare organizations have been recognized as successful in enterprise-level transformation to create healthcare delivery systems that are safe, effective, patient-centered, timely, efficient and equitable. Many of these organizations have specifically cited the development, deployment and integration of enterprise-level deployment of Lean Management Systems as key to their transformational efforts. Given the intense national interest in improving quality, efficiency and efficacy of healthcare delivery systems, a greater understanding of the strategies utilized by these organizations was required in order to provide an understanding of the mechanisms that drive successful, sustained, enterprise-level transformation. We conducted a realist review of large system transformation utilizing enterprise-level Lean Deployment methods within healthcare organizations. Synthesis and analysis of the results from this review indicate that there are five primary strategies associated with successful healthcare-based Lean deployments: Respect for People; Strategic Alignment; Strategic Deployment; Large Scale System Improvement Efforts; and Small-Scale, Local Improvement Efforts. Additional findings from this review indicate that the applications of the specific mechanisms with these strategies are emergent within multiple transitional phases spanning 6-8 years. To supplement the findings from the realist review, a series of dynamic hypotheses and system dynamics model was created in order to explore how the mechanisms and context interact to drive phase transitions within healthcare-based enterprise-level Lean deployments. The results from this model indicate that no steady state initial conditions exist that support sustained enterprise-level transformation and that the emergent nature of these deployments is necessary to overcome constraints related to the organizational capacity and capability. Additionally, we investigate the design and deployment of enterprise-level Lean programs in order to increase rate of success and decrease deployment cycles. "
