The purpose of this work is to evaluate how a docking station can be more future proof, environmentally friendly and satisfy the customers’ needs more. The docking station in focus of this project is owned by LVI, and used with one of their cameras MagniLink S. When comparing the results of the new docking station and the current docking station, the new docking station is more future proof, environmentally friendly and satisfies the customers’ needs more. In the end it is established that following steps should be followed during the development of a docking station: -          Make sure that the cables are reliably fastened into the docking station and that the connectors can handle the docking force. -          Design to use more material with lower environmental impact and ensure that the material fulfils the product requirements and objectives. Use as small amount of material as possible. -          Prioritize the customers’ expressed and unexpressed needs as one of the highest priorities during the development process.

This thesis project is about designing and developing an already existing testing device for a new invented Doctor Blade. A doctor blade is a blade used for creping tissue paper of a rotating cylinder, Yankee Cylinder. The old testing device was incomplete in a way that a rotating cylinder was missing, hence the tested blade is not loaded properly. The old testing device already contained the doctor blade holding device and the pulling device (pulling the creping blade). These two devices are transferred to the new testing device without any redesign within them. The adding of a rotating cylinder/roller required some new redesign regarding the testing device. The main beam (beam carrying all elements) is replaced with a larger one in order to fit the roller and is elongated in order to run longer tests. The new beam has a larger cross section in order to minimize the risk of bending. The main beam is supplied with five small beams, welded onto it, three for attaching the holding device and two for attaching the roller. The dimensions of these small beams are chosen in order to put the roller on the right position according to the creping blade. An electric motor is added to the new testing device in order to drive the roller with a chain. This required two sprockets, one for the motor and one for the roller shaft. The sprockets are chosen with a pitch diameter ratio matching the gearing required. FMEA-analysis is done on the whole design where five failure modes were chosen to be included, bending of the main beam and motor beam, screw joints of the same beams and sprocket-chain mechanism. Some FEM-analysis was required in order to detect the bending of the beams and measuring the loading on the screw joints. The screw joint loading achieved from the FEM-analysis is used for the theoretical screw joint calculations. The FMEA-analysis implied that four of the analyzed failure modes have acceptably low risk factor and dos not require any further actions. However one received a high risk factor, the chain-sprocket mechanism, the risk of clamping fingers. This is solved by adding a protecting house/shell made of sheet metal. Measurements were done on the old and the new testing device regarding the required force for pulling the creping blade and the pressure distribution between the creping blade and the beam (and roller in the new testing device). The improvement of the pulling force values is rather due to the new designed doctor blade than due to the new testing device. The new testing device is however more appropriate than the old one hence the added roller and the tests shows that it is functional as well. / Projektet handlar om design och utveckling av en redan existerande testrigg för ett nyuppfunnet kräppningsblad. Ett kräppningsblad är det bladet som just kräpper av papper från en roterande cylinder, s.k. Yankee Cylinder. Den gamla testriggen var inte komplett och saknade en roterande cylinder, därav kräppningsbladet belastades inte ordentligt. Den gamla testriggen innehöll redan en hållaranordning för kräppningsbladet och en dragstation (som drar kräppningsbladet). Dessa två delar förflyttades till den nya testriggen utan några korrigeringar. Tillägget av en roterande cylinder/vals krävde ny design för den nya testriggen. Huvudbalken (balken som bar alla delar) ersattes av en större balk för att den nya valsen ska få plats. Nya balken är även längre i syfte att kunna köra längre tester. Tvärsnittsarean hos den nya balken är större i syfte att minimera risken för böjning. Fem små balkar är fastsvetsade i den nya huvudbalken, tre för fästning av hållaranordningen och två för fästning av valsen. Placeringen av dessa fem balkar valdes i syfte att placera valsen i rätt position enligt kräppningsbladet. En elektrisk motor tillfördes till den nya testriggen i syfte att driva valsen med en kedja. Detta krävde två nya kugghjul, en för motorn och en för valsaxeln. Delningsdiametern för de två kugghjulen valdes med en viss kvot som motsvarar den utväxlingen som krävs. FMEA-analys utfördes på hela testriggen dör fem olika haveriorsaker inkluderades, böjning av huvudbalken och motorbalken, skruvförbanden på dessa två balkar och till sist kugghjul-kedja mekanismen. FEM-analys krävdes för beräkningar av böjningen på balkarne och för belastningen på skruvförbanden. Belastningen på skruvförbanden uppnåd från FEM-analysen användes senare i de teoretiska beräkningarna av skruvförbanden. FMEA-analysen angav att fyra av de fem analyserade haveriorsakerna har accepterad låg riskfaktor och kräver inga åtgärder. Dock så visade det sig att en haveriorsak fick en för hög risk faktor, kugghjul-kedja mekanismen, risken att klämma fingrar.Detta problem löstes med hjälp av att designa ett skyddshus /skal av plåt. Mätningar gjordes på den gamla och den nya testriggen på dragkrafter och tryckfördelning mellan kräppningsblad och balk (vals i den nya testriggen). Förbättringen av värden på dragkrafterna beror mer av det nydesignade kräppningsbladet än av den nya testriggen. Hursomhelst är den nya testriggen lämpligare än den gamla med tanke på tillförseln av valsen och dessutom så visar testerna att den är funktionell.

Master´s thesis deals with the identification and evaluation of mistakes on the production line and their prevention. For the purpose I chose FMEA method. Theoretical part contains description of kinds of FMEA and their application. In the following part description and analysis of current state of production process of the product at NORMA Czech, s.r.o. was made. All important information were recorded to FMEA forms and finally measures for the most critical failures were designed.

This diploma thesis deals with the risk associated with fish production. Selected risks are further taken into account. The risks are further described and addressed using the FMEA matrix. The thesis contains a mathematical model that solves the optimal population of the pond in order to maximize profits. The model includes fixed input parameters, which includes the price of hatchery material and the market price of fish. Furthermore, the model contains random input parameters that are limited by the intervals and includes the growth coefficient and the size of the population in the pond. The optimization model is based on simulated data, which are based on real data and statistically determined estimates. The used data are processed into tables in MS Excel for better visualization. GAMS software is used for software implementation of the model.

The diploma thesis deals with analysis and assessment of risks in testing laboratories, where the work with risks is an unrecognized area. A part of the thesis defines risks according to standard revision 17025:2017. Subsequently, these risks are processed by selected methods, which are used for qualitative and quantitative evaluation. Risks determination in the thesis is based on methods Risk Matrix, Failure Modes & Effects Analysis (FMEA) and Bow Tie Analysis. Introducing possibilities and patterns of described methods to testing laboratories is the main aim of the thesis, this could be a way to increase their chance to get a new accreditation.

This Thesis deals with creating system for controlling risks based on critical analysis for chosen company. The company is called Vinařství Kovář and it's owned by Mr Miroslav Kovář, who is a wine producer. The first part of the Thesis is focusing on theory of controlling risks. The second part analyses current state of the company, it's risks and evaluation of the risks. The assessment of the risk is done by doing an FMEA analysis. This helps to find the most severe risks which are then eliminated with set actions. The last part of the Thesis contains suggestions of controlling the risks for the company to prevent or minimalise potential risks.
