Balansering och tidsoptimering av materialsatsning till F12-monteringen på Parker PMDE Trollhättan / Balancing and time optimization of kitting to the F12-assembly department at Parker PMDE Trollhättan

Asad, Ahmed, Sallander, Rikard January 2016 (has links)
I industriföretag används managementverktyg för att utveckla och effektivisera verksamheten så att ledtider och slöseri reduceras i samtliga processer. Parker PMDE Trollhättan tillverkar hydraulikmaskiner. Sedan 90-talet har Parker bedrivit verksamhetsutveckling enligt management principer i Lean Production. Ett nästa steg i Parkers ständiga förbättringsarbete var att undersöka möjligheter att utveckla en materialsatsningsavdelning så att en person kan förse monteringen med material tillräckligt snabbt utan att extra resurser behöver tillsättas. I dagsläget råder det obalans gentemot takttider i monteringen och det tar längre tid för satsningen att plocka ihop fyra satser än vad det tar för monteringen att förbruka dessa satser.Målet med examensarbetet var att ta fram förbättringsförslag där en person får förutsättningar att plocka ihop material till montering av fyra hydraulikmaskiner på mindre än 16 minuter. Delmålen var att göra en kartläggning av tider och arbetsmoment vid satsningen. Avgränsningarna i projektet var att inte undersöka processer utanför satsningen. Examensarbetet utformades efter DMAIC-metodiken, som är en projektmodell för faktabaserad problemlösning och tydlig struktur. Metoderna som användes vid insamling av data var observationer och analys av videoinspelat material som utfördes i programvaran AviX Method. Videoinspelningarna kategoriserades som olika aktiviteter i satsningsprocessen där gång, plock, scannertid, förmontering och övrig tid var de största kategorierna. Arbetsmoment identifierades som var tidskrävande och ej tillförde värde i processen. Mätningarna låg till grund för generering av lösningsförslagen.Baserat på ovanstående resultat och med hjälp av brainstorming genererades lösningsförslag tillsammans med produktionstekniker och materialhanterare. De lösningsförslag som uppfyllde målet med projektet att plocka en 4-sats under 16 minuter var pick by voice, pick by light, ringscanner och flytt av kilpress. Pick by voice anses vara lösningen som företaget bör införa eftersom den reducerar plocktid, scannertid och är ett flexibelt system. Ytterligare två lösningsförslag togs fram som inte uppfyllde målet men uppfattas som värda för företaget att utreda vidare utifrån Lean Production och ergonomiska skäl. De lösningsförslagen som inte uppfyllde målen bestod av en förändring av plockrundan och införande av en magnetlyft. / In industries, the management tools of Lean Production are used to develop and streamline operations in a way to reduce waste and lead times in all processes. Parker PMDE in Trollhättan manufactures hydraulic machines. Since the 90´s, Parker has pursued business development under the management principles of Lean Production. One of the next steps in Parkers continuous improvement was to explore opportunities to develop a kitting department so that a worker could provide the assembly with the material quickly without surplus resources. In the current situation, there is an imbalance from the kitting station towards the tact times in the assembly station because it takes longer at the kitting station to pick materials for four hydraulic machines, than it takes for the assembly station to consume these kits of materials.The aim of the thesis was to develop suggestions for improvement where a worker could perform the kitting process in less than 16 minutes. The interim objectives were to do a survey of the times and activities within the kitting process. The boundaries of the project was not to examine processes outside the kitting station. The project was designed according to DMAIC methodology, which is a project model for fact-based problem solving and clear structure. The methods used in the data collection were observation and analysis of video footage applying the software called AviX Method. Video recordings were categorized as different activities in the kitting process such as transport, picking, scanner time, pre-assembly and uncategorized time. Activities that were time consuming and did not add value to the process were identified. These data measures were the basis for the solution proposals.Based on these results and using brainstorming, solution proposals were generated together with the engineers and material handlers. The solution proposals that met the objective of the project of picking a 4-set of materials in 16 minutes were: Pick by voice, Pick-by-light, Ring Scanner and Relocation of one pre-assembly operation. Pick by voice is considered to be the most appropriate solution for the company since it reduces picking times, scanning times and is a flexible system. Two more proposed solutions were developed that did not meet the objective of the project, but are considered worth investigating further based on Lean Production and ergonomic reasons. These proposed solutions consisted of changing the picking route and the installation of a magnetic lift.

Evaluating Different Last Mile Logistics Solutions : A case study of SF Express

Ding, Zhe January 2014 (has links)
Compared to the highly developed logistics industry in USA, the Chinese logistics industry is still underdeveloped because of poor infrastructure and ineffective management capability. In terms of these realities, the most important bottleneck of the Chinese logistics industry is the last mile delivery problem, which holds the highest cost in the whole logistics process. To find ways to solve the problems with last mile delivery has become significant and urgent for Chinese logistics service providers. The purpose of the study is to deepen and enrich the knowledge on last mile logistics in China. This is carried out with the help of the case companies SF Express and Property Management Company together with an investigation of last mile delivery alternatives in China. Related to the research question, a case study was carried out focusing on one business process. The data collection methods used include: interview, telephone or email contact, and survey. Intelligent locker and the pick-up delivery solution could solve last mile logistics problems by different ways, especially with specific limitations in Chinese market. These delivery alternatives are highly possible to be adopted and generalized by different logistics service providers in China if not concerned about the cost or density of orders. The current business mode of supermarket in China cannot fulfill the demand from an overwhelming number of customers. Costs for both pick-up stations are acceptable, and the cost is a positive factor for pick-up station mode. The higher density of orders, the higher possibility of different time-window may require, and high competitive advantage of intelligent locker can be achieved. The high density of orders for intelligent locker is a positive factor. The cost for intelligent locker is a very negative factor, which seriously limits the popularization of this delivery alternative. Keywords: Last mile logistics, Intelligent locker, Pick-up station, Delivery alternatives

EQUINE PREANTRAL FOLLICLES: ULTRASOUND-GUIDED BIOPSY PICK-UP METHOD TO HARVEST OVARIAN TISSUE FOR IN VITRO PROCESSING, EVALUATION AND CULTURE

Haag, Keith 01 May 2012 (has links)
The mammalian ovary contains a vast reserve of oocytes, most of which are enclosed within preantral follicles. A Biopsy Pick-Up (BPU) method was tested to determine the feasibility of retrieving preantral follicles from mare ovaries in vivo. BPU fragments were collected from 5 to 21 yr old mares during the breeding season and processed using a tissue chopper, submitted to histological analysis or submitted to in vitro culture for 1 or 7 days. In conclusion, the BPU method is a reliable way to repeatedly harvest large numbers of viable, morphologically normal preantral follicles from living mares without affecting ovarian function or general reproductive health. Additionally, equine preantral follicles undergo development and growth when submitted to in vitro culture in α-MEM for 7 days, with some follicles maintaining morphological normality throughout. These technologies could be used in the future to enable the use of numerous oocytes present within the equine ovary to preserve genetic material or for large-scale embryo production.

Dórea, Marcus Dantas 30 March 2012 (has links)
Made available in DSpace on 2016-08-29T15:37:23Z (GMT). No. of bitstreams: 1 tese_5660_DISSERTAÇÃO - MARCUS DÓREA.pdf: 959070 bytes, checksum: b826fbc0dc1185e5661f7622a98c7491 (MD5) Previous issue date: 2012-03-30 / Objetivou-se com este estudo avaliar a taxa de folículos residuais pós-aspiração de folículos ovarianos de 8 e 12 mm de diâmetro, por meio da avaliação dos fatores endócrinos, analisando a interferência destas estruturas no desenvolvimento normal da dinâmica de crescimento. Foram selecionadas vacas da raça Holandesa (N=13) não lactantes e com dois ciclos estrais normais consecutivos; estas foram tratadas com 500mg de cloprostenol sódico (Sincrocio®) e 3 mg de norgestomet (Crestar®) (D0), 2 mg de benzoato de estradiol (Sincrodiol®) (D1), após a emergência da onda folicular foram distribuídas aleatoriamente em dois tratamentos caracterizados pela ausência ou presença de implantes de norgestomet, cada tratamento dividido em dois grupos: presença do implante e folículo de 8 mm (G1), ausência do implante e folículo de 8 mm (G2), presença do implante e folículo de 12 mm (G3) e ausência do implante e folículo de 12 mm (G4). O monitoramento ultrassonográfico (Esaote Pie Medical®) foi realizado duas vezes ao dia com intervalo de 12 horas. Os folículos ovarianos foram aspirados com 8 e 12mm e avaliados quanto à presença do resíduo ao processo de aspiração, quando residual, eram aspirados novamente. Os dados de dinâmica de crescimento folicular, perfil hormonal do plasma sanguíneo e do fluído folicular foram verificados quanto à distribuição normal, pelo teste de Shapiro-Wilk e comparadas nos diferentes tratamentos pelo teste t de student. Os dados de perfil de esteroidogênico dos folículos aspirados em diferentes diâmetros foram analisados pelo SAS GLM procedure para o principal efeito de tratamento e as comparações foram feitas pelo teste F. O nível de significância adotado foi de 5%. O tratamento com progestágeno não afetou o crescimento folicular. A taxa de folículo residual foi de 74.6%. O tratamento com progestágeno não afetou (P>0.05) o percentual de folículos residuais, independente do diâmetro do folículo, no entanto, o efeito do diâmetro folicular aproximou a significância estatística (P=0.07). Os folículos residuais cresceram cerca de 5 mm ao dia. Dos folículos residuais aproximadamente 65% se tornaram folículos ativos, 12% folículos luteinizados e 23% folículos inativos. Conclui-se que a presença de folículos residuais ocorre na maioria dos folículos aspirados com maior frequência em 12 mm e grande parte ativos e com elevada concentração de estradiol.

Teorema de Pick e teorema espacial tipo-Pick: demonstraÃÃes e aplicaÃÃes no ensino mÃdio / Pick's theorem and spatial theorem type-Pick: demonstrations and applications in high school

Paulo de Oliveira Meneses 18 June 2016 (has links)
CoordenaÃÃo de AperfeÃoamento de Pessoal de NÃvel Superior / Estudos mostram que o desempenho do aluno em MatemÃtica nÃo à satisfatÃrio, pois apenas uma pequena parcela desses alunos tem os conhecimentos necessÃrios para prosseguir nos estudos. O presente trabalho visa criar ferramentas que possam auxiliar e melhorar as prÃticas em sala de aula, mais precisamente nos estudos de Geometria. Apresentaremos o Teorema de Pick, que visa calcular a Ãrea de um polÃgono simples usando contagem, analisando os pontos do bordo e do interior da figura em uma rede fixada, tornando-se uma ferramenta de uso simples e poderosa para a compreensÃo do estudo de Ãreas. Logo em seguida, mostraremos o Teorema de Reeve que, de modo anÃlogo a Pick, calcula o volume de um poliedro convexo contando os seus pontos de rede, trabalhando em uma rede secundÃria de pontos Z3n, realizando um elo entre Geometria e contagem. / Studies show that the performance of students in Mathematics is not satisfactory, since only a small portion of these students has the knowledge needed to pursue studies. The present work aims to create tools that can assist and improve classroom practices, more precisely in the studies of Geometry. We will present by counting Pick's Theorem, which calculates the area of a simple polygon by counting the points of the boundary and of the interior of the figure on a fixed lattice, making it a powerful tool of simple use for the understanding of the study of areas. Then we will present Reeve's Theorem that, similarly to Pick's, calculates the volume of a convex polyhedron by counting their lattice points, working on a secondary lattice of points Z3n, making a link between Geometry and counting.
