Resumen

The performance of production cell for motorcycle engine parts is critical for the competitive capacity of motorcycle products. In order to meet the maximum beneficial result with minimum cost, simulation approach is applied to find the best improvement scheme of the production cell. Performance indicators including rate of comprehensive utilization of equipment and rate of utilization of workers are established. Two different production schemes are analyzed based on work study. Flexsim simulation software was used to simulate and evaluate the schemes. The comparative simulation results show that simulation provides an effective way to find the best improvement scheme by evaluating overall performance of the production cell, instead of partial performance evaluation by traditional work study methods.

Resumen

Abstract Nowadays there are commercial tools and academic solutions that support and contribute to Virtual Commissioning (VC). However, the main obstacle which hinders the broader application of VC in practice is the modeling time and effort required to create a proper simulation model. The modeling is also separated from the current project development lifecycle. This paper presents a semi-automatic method to transform the 3D geometry model of a production cell into a simulation-enabled virtual representation (i. e., a high fidelity simulation model of the cell). The geometry is combined with dynamic behavior which is a behavior description modeled intuitively based on VDI 2860. The entire method is embedded into a virtual commissioning workflow and is exemplified by a production cell with conveyors. Several commercial modeling and simulation tools are used and combined in the workflow to demonstrate the applicability. The presented methodology bases on AutomationML.

Resumen

In this paper, we have discussed on the performance of the knowledge sharing for the multiple robot system which is equipped with the advanced telecommunication devices. This has enabled the mobile robots to perform advanced communication. We propose the utilization of the knowledge sharing robot system at manufacturing scenes, and demonstrate the performance by a simplified simulation. Applying this knowledge sharing system, which helps to improve the balance of the line, the improvement of the productivity and quality was observed. Consequently, the cost reduction and improvement of the efficiency shall be expected by introducing more sophisticated algorithm of knowledge sharing and distribution.

Resumen

Relatively high cost of energy produced by solar cells prevents them from being used widely. One of the ways to address this problem is to create new, cost efficient solar cell production technologies. This presentation analyzes how, by applying self-formation principles it is possible to decrease number of photolithography processes used in high efficiency solar cell production, thus significantly reducing the cost of solar cell itself. All known planar technologies can be described based on self-formation principles; new microchip and integrated circuit technologies were created using self-formation as well. It is therefore natural to extend self-formation to solar cell technology. This presentation provides specific aspects of self-formation simulation as related to solar-cell technology. The object of the simulation is a cross-section of solar cell in two-dimensional Euclidean space and it.s evolution over time. Such kind of solar cell approximation simplifies the model, yet keeps all essential characteristics of the solar cell. The cross-section contains geometrical figures which approximate objects in the solar cell. Each figure is assigned with an integer parameter, approximating physical material. According to self-formation principles, evolution of each figure depends only on geometrical configuration of the figure itself, the parameter and interaction rules. Interaction rules define change of neighbouring points and approximate technological processes (etching, oxidation, coating etc). Combination of such processes enables construction of required solar cell configuration, with only minimum use of photolithography processes. Self-formation is simulated by two-dimensional 8-neighbour cellular automata based mechanism.

Resumen

Control software plays an important role in industrial automation. Several domainspecific languages for control software implementation were designed and accepted in industry. Structured Text (ST)[1] is one of these languages. It is standardized by IEC 61131-3 standard and designed for programmable logic controllers. In this thesis two implementations of control software were developed: Java implementation as a reference model, and ST implementation as a test scenario for ST to C compiler. The functionality of both implementations was compared using the simulation model. It was concluded that resulting ST control software provides the same functionality as its reference model.

Resumen

This final thesis was performed at Ecole Nationale Supériure D’Arts et Métiers (ENSAM) in Lille, France. The aim of the thesis has been to use two different simulation tools to analyse an existing production cell with focus on industrial engineering. The possible use and the usability of the simulation tools are also studied. The models built for simulation have been used to gather data about the cell. After analyse and discussion about the data we came to the following conclusions. The bottleneck in the cell is the Stäubli. A cheap and simple way to improve the cell is by adding new decision points (sensors) to it. The most efficient location of the new decision points is before and after the Stäubli. The production rate reaches its maximum rate for both settings with eight pallets. If the improvements are implemented then there is no reason to change the speed of the conveyor. With basic settings the speed can be increased for better productivity. The most efficient production type for short setup times is single, for both settings. Delmia is useful for visual representation. It’s also useful for measurements of time and distance since the accuracy is very high. Delmia is useful as common platform when to discuss and explain thoughts and ideas about a project. Flow simulation in Quest provides a great understanding of the production and the behaviour of the cell. It is very easy to get data in and out of the program and to compare results and impacts of changes.

Resumen

Purpose:The primary purpose of the current thesis is to develop a virtual model using discrete event simulation (DES), which aims at supporting the decision-making process regarding automation solution proposals for SMEs. Method:The research approach is positivism, and it considers quantitative and empirical information. A literature search is conducted to generate a base for obtaining the theory required for the current report to answer the research questions. This search included the trace of relevant and reviewed topics regarding automation, discrete event simulation, and production lines. Then, a scenario simulation is designed and studied based on empiric knowledge and how automation would affect it, followed by a collection of information from the simulation iterations. Findings& Analysis: Two scenarios are presented. One with a fully manually operated assembly line consisting of only human operators and a second scenario, a semi-automated assembly line that includes some robots in specific areas doing specific operations. The two scenarios are simulated to check to what extend the KPI’s and parameters improved between each scenario. The experiment result concludes that by introducing automation elements in the production line, there is an increase in the overall efficiency, throughput rate, and a considerable gap against humans in WIP. Conclusions and recommendations: The results obtained from the experimentation in discrete event simulation software and study from previous research show that discrete event simulation has a significant contribution when considering a decision-making tool's role. Since it allows to understand and study the specific scenario by imitation and try different solutions in the same production system, it also allows studying several indicators from the scenarios to be checked to what extent they could be improved. Delimitations: The current thesis includes several delimitations. First, it focuses only on an operational level. Also, this study consists of a specific type of product with many variants, and finally, there are only two scenarios studied: a fully manual scenario and a semi-automated scenario with the presence of robots.

Resumen

Volvo is continually updating and replacing their equipment and want to investigate the possibility to shorten the time it takes to implement changes and shorten the time in commissioning projects. The use of an emulation model of a production cell can shorten the commissioning time since the equipment and sequence of the cell can be thoroughly tested before implementation. Volvo also wants to investigate the possibility to validate equipment using emulation. The main objectives are to find an emulation software that suits Volvo’s needs and build an emulation model of an actual production cell at Volvo called G750. A literature review was performed in which the authors gained knowledge about virtual commissioning, simulation and emulation and the usage of these. A market survey was conducted in order to find emulation software that could handle Volvo’s complex production equipment consisting of ABB robots and Siemens PLC. A method for building emulation models of existing production equipment was found during the literature review. The software used to build the emulation model was Simumatik3D. Other software used to make the model as realistic as possible includes RobotStudio, WinCC and PLCSIM. The emulation model handles approximately 350 inputs and outputs. When the emulation model was finished experiments were conducted in order to answer research questions and to reach the main objectives. The experiments validate that the emulation model is representative of the real production cell regarding programming, fail scenarios and movement.

Resumen

This master thesis is the last part of the master program Production Engineering and Management at the Royal Institute of Technology, KTH, in Stockholm. The thesis is conducted at Exeger Operations AB, in short Exeger. The company is in an expansion phase and wants to prepare for future production expansion. Thus, a simulation capability to test future production scenarios was desirable. The problem definition was defined by the company together with the authors and led to a literature study within simulation, TPS and Lean manufacturing. Following the literature study, a current state map was produced to achieve sufficient understanding of the production flow at the company. A simulation model was then built. The model was used to test three different ”what-if” scenarios. Buy or Optimize, Future ratio 3:1:1 and Buy or SMED. The authors’ findings in the Buy or Optimize scenario suggest that optimizing the process time in the printers is far better, from multiple perspectives, than investing in new machinery. A 3:1:1 ratio of printers, sinter 1 and assembly station was developed using the simulation model to achieve leveled production flow of these specific processes. Lastly, conducting a SMED on the sinter 1 machine, the setup-,and wait-times achieved a theoretical reduction up to 75 % by altering the SOP and allocating additional preparatory space, in accordance with Lean philosophy. This change would offer the same improvement to a full-scale production as investing in a new sinter 1 according to the simulation model. Future work may consist of Layout Planning and adopting the simulation model to new prerequisites.

Resumen

The aim of this thesis was to describe how a manual assembly process of polycarbonate sheets for heat exchangers can be automated with an industrial robot. The objectives were to design suitable robot cell concepts and simulate them to describe how the automated process could be done and to present which machines and equipment that could be used. Additionally, productivity rates and investment costs was to be calculated.The project started with a situation assessment and a literature review. Experts and suppliers of robotic equipment were consulted, and the results served as a basis for the concept generation process. Several concept ideas were evaluated, and three ideas using adhesive for the assembly were chosen for further studies and simulation. Existing products and machines were used in the designs when possible. By modeling and simulating the cells in simulation software, feasible cell designs was created, and cycle times were measured.The three proposed solutions all utilize an industrial robot, a vacuum gripper and adhesive as the assembly method. Two of the concepts has the robot attending different adhesive dispensing machines; one gantry and one conveyor. In the third concept, the robot applies the adhesive. The cell design that achieved the lowest cycle time in the simulations was the conveyor concept, with a cycle time of 21 seconds per sheet. The conclusion of the study is that investing in a robot cell would increase productivity.
Syftet med detta arbete var att designa en robotcell anpassad för tillverkning av värmeväxlarpaket i moduler. Målet var att besvara hur tillverkningen av värmeväxlare kan automatiseras samt vilken robot och övriga verktyg och maskiner som kan användas. Vidare skulle den möjliga produktionstakten och investeringskostnaden för designförslagen beräknas. Arbetet inleddes med en nulägesanalys och en litteraturstudie. Ett flertal experter och leverantörer inom automationsområdet konsulterades. Resultaten från detta låg till grund för en konceptgenereringsprocess i vilken ett flertal designidéer togs fram. Tre av dessa designförslag valdes ut för vidare studier och simulering. Genom att modellera och simulera robotcellerna kunde de utformas realistiskt och möjliga cykeltider beräknas. De tre designförslagen använder alla en robotarm, ett vakuumgripdon samt lim som metod för monteringen. Två av koncepten består av en medelstor robotarm som betjänar en limappliceringsmaskin. I ena konceptet är det en kartesisk robot med limbord som används för limappliceringen, i det andra är det ett transportband som för plastskivan under ett antal limpistoler. Det tredje designförslaget låter en större robot, utrustad med verktygsväxlare, utföra alla moment i processen genom att den byter verktyg mellan vakuumgripdon och limpistol. Det koncept som uppnådde den lägsta cykeltiden i simuleringarna var lösningen med rullbandet, med en cykeltid på 21 sekunder per skiva. Studiens slutsats är att en investering i en robotcell skulle leda till ökad produktivitet jämfört med manuell produktion.

Resumen

In line with the company-wide CS09 project being carried out at Volvo CE Components, Cell 14 will have changes in terms of distribution of machines and parts routing to meet the lean manufacturing goals established. These changes are of course dependant on future production volumes, as well as lot sizing and material handling considerations.

In this context, an important emphasis is given to the awareness of the performance measures that support decision making in these production development projects. By using simulation as a confirmation tool, it is possible to re-assess these measures by testing the impact of changes in complex situations, in line with the lean manufacturing principles.

The aim of the project is to develop a discrete event simulation model following the methodology proposed by Banks et al (1999). A model of Cell 14 will be built using the software Technomatix Plant Simulation ® which is used by the Company and the results from the simulation study will be analyzed.

Resumen

Over the past two decades, Lean Production has begun to replace traditional manufacturing techniques around the world, mainly due to the success of the Toyota Motor Company. One key to Toyota's success that many American companies have not been able to emulate is the transformation of their suppliers to the lean philosophy. This lack of supplier transformation in America is due to a variety of reasons including differences in supplier proximity, supplier relationships, supplier performance levels, and the ordering policies used for supplied parts. The focus of this research is analyzing the impact of ordering policies for supplied parts of a manufacturing cell utilizing Lean Production techniques. This thesis presents a simulation analysis of a multi-stage, lean manufacturing cell that produces a family of products. The analysis investigates how the ordering policy for supplied parts affects the performance of the cell under conditions of demand variability and imperfect supplier performance. The ordering policies evaluated are a periodic-review inventory control policy (s, S) and two kanban policies. The performance of the cell is measured by the flowtime of the product through the cell, the on-time-delivery to their customer, the number of products shipped each week, the amount of work-in-process inventory in the cell, the approximate percentage of time the cell was stocked out, and the average supplied part inventory levels for the cell. Using this simulation model, an experimental analysis is conducted using an augmented central composite design. Then, a multivariate analysis is performed on the results of the experiments. The results obtained from this study suggest that the preferred ordering policy for supplied parts is the (s, S) inventory policy for most levels of the other three factors and most of the performance measures. This policy, however, results in increased levels of supplied part inventory, which is the primary reason for the high performance for most response variables. This increased inventory is in direct conflict with the emphasis on inventory and waste reduction, one of the key principles of Lean Production. Furthermore, the inflated kanban policy tends to perform well at high levels of supplier on-time delivery and low levels of customer demand variability. These results are consistent with the proper conditions under which to implement Lean Production: good supplier performance and level customer demand. Thus, while the (s, S) inventory policy may be advantageous as a company begins transitioning to Lean Production, the inflated kanban policy may be preferable once the company has established good supplier performance and level customer demand.

Resumen

Pyrolysis of hydrogen sulfide has been studied for the treatment of hydrogen sulfide with simultaneous production of hydrogen and sulfur. This novel treatment method has been studied experimentally to provide fundamental information on the overall kinetic parameters. Numerical simulation of thermal pyrolysis of hydrogen sulfide is studied and the results obtained from the modified detailed chemical reaction mechanism are validated with the experimental data. The simulation results agreed favorably well with the experimental data for all examined temperatures up to 1473K. The thermal pyrolysis of hydrogen sulfide has been studied at residence times of 0.4 to 1.5 seconds and at temperatures of 1273–1473K. Experiments and simulations were also conducted using hydrogen sulfide diluted with 95% nitrogen using a heated quartz plug flow reactor to avoid any catalytic effects and excessive build of sulfur during experimentation. Numerically plug flow type reactor model was used to simulate the hydrogen sulfide thermal pyrolysis. The available mechanism in the literature provided poor match with the experimental data at temperatures higher than 1273 K. A modified mechanism is proposed and validated with our experimental data. Both simulations and experimental results showed increased conversion of H2S to hydrogen at increased temperatures. The increase in temperature reduced the residence time required to reach a steady asymptotic equilibrium value. Based on the qualitative agreement between simulations and experimental data under the investigated conditions, the reaction pathways as well as the most dominant reactions on hydrogen sulfide thermal pyrolysis are also presented. These results assist our efforts in the development of new technologies for hydrogen sulfide treatment.

Resumen

Anaerobic Digestion is a biological process that takes place naturally when microorganisms break down organic matter in the absence of oxygen. In an enclosed chamber, controlled anaerobic digestion of organic matter produces biogas which is predominantly methane. The produced methane then can be directly used for rural cooking; or after certain conditioning, can be used in onsite power generation, heating homes or as vehicular fuel. Besides, food waste is increasingly becoming a major problem in every society imposing serious economic and environmental concerns. For this reason, many contemporary researches are emphasizing in finding sustainable solutions to recycle and produce energy from such waste. In this context, this paper aims to study and optimize the production of biogas from food waste (rice). For the experiment, an existing wet digestion biogas plant installed in Islamic University of Technology was used. The food waste (rice) for the research was collected from the cafeteria of Islamic University of Technology. Furthermore, a process simulation was performed by PROII software to estimate the methane production rate. Eventually, the simulated and experimental results were compared. The duration of the study period was 120 days. The experimental results showed that an average specific gas production of 14.4 kg-mol/hr can be obtained for 0.05 kg-mol/hr of starch loading rate. In case of the simulated results, the gas production was found to be 19.82 kg-mol/hr for the same loading rate of starch. The percentage of methane and CO2 obtained in the biogas plant was 69% and 29% respectively.

Resumen

Hydrogen fuel cell technology is currently capable of providing adequate power for a wide range of stationary and mobile applications. Nonetheless, the sustainability of this technology rests upon the production of hydrogen from renewable resources. Among the techniques under current study, the chemical reforming of alcohols and other bio-hydrocarbon fuels, appears to offer great promise. In the so called autothermal reforming process, a suitable combination of total and partial oxidation supports hydrogen production from ethanol with no external addition of energy required. Furthermore, the autothermal reforming process conducted in a well insulated reactor, produces temperatures that promote additional hydrogen production through the endothermic steam reforming and the water-gas shift reactions, which may be catalyzed or uncatalyzed, with the added benefit of lowered carbon monoxide concentrations. In this study, an adiabatic ethanol reforming reactor was simulated assuming the reactants to be air (21% O2 and 79% N2) and ethanol (C2H5OH) and the products to be H2O, CO2, CO and H2, with all constituents taken to be in the gaseous state. The air was introduced uniformly through a ring around the side of the reactor and the gaseous ethanol was injected into the center of one end, with products withdrawn from the center of the opposite end, to create an axisymmetric flow field. The gas flows within the reactor were assumed to be turbulent, and the chemical kinetics of a simple four reaction system was assumed to be controlled by turbulent mixing processes. Air and fuel flow rates into the reactor were varied to obtain six different levels of oxidation (air-fuel ratios) while maintaining the same total gaseous mass flow out of the reactor. The numerical results for the reacting flow show that hydrogen production is maximized when the air-fuel ratio on a mass basis is held at approximately 2.8. These findings are in qualitative agreement with observations from previous experimental studies.

Resumen

A dynamic autothermal methane reformer model has been developed and tested for the production of a hydrogen- and carbon monoxide-rich syngas. This study looks at potential advantages and disadvantages of an autothermal reformer, both operating in stand-alone mode and in conjunction with a high temperature fuel cell stack. The model uses a conservation of moles as the fundamental continuity relationship, and applies basic energy conservation equations to simulate both the gas and the catalyst bed energies. Chemical kinetic expressions using empirical constants for the Arrhenius rate terms that describe steam reformation of methane and partial oxidation of methane are simultaneously solved to provide an accurate picture of the reaction dynamics. This paper presents dynamic responses of reformer outlet temperature, hydrogen mole fraction, reaction rates and methane conversion to the perturbation of the reformer inlet variables of steam-to-carbon ratio, oxygen-to-carbon ratio and inlet gas temperature. Also explored is the concept of catalyst “light-off,” where there is found to be a lower temperature limit above which catalyst activity is substantially increased.

Resumen

La géothermie de faible profondeur avec des pompes à chaleur correspond à l’état actuel de la technique et est déjà largement répandue en Suisse. Au sein du futur système énergétique, la géothermie de moyenne à grande profondeur (1 à 6 km) devrait également jouer un rôle important, notamment en matière de fourniture de chaleur pour les bâtiments et les process industriels. Cette forme d’utilisation de la chaleur géothermique nécessite un sous-sol bien perméable, permettant à un fluide – généralement de l’eau – d’engranger la chaleur naturellement présente dans la roche et de la transporter jusqu’à la surface. Dans les roches sédimentaires, cette condition est généralement vérifiée du fait de la structure naturelle, tandis que dans les granites et les gneiss la perméabilité doit être générée artificiellement par injection d’eau. La chaleur ainsi récupérée augmente au fur et à mesure de la profondeur de forage : la température souterraine atteint environ 40°C à 1 km de profondeur et environ 100°C à 3 km de profondeur. Pour entraîner une turbine à vapeur en vue de produire de l’électricité, des températures supérieures à 100°C sont nécessaires. Étant donné que cela implique de forer à des profondeurs de 3 à 6 km, le risque de sismicité induite augmente en conséquence. Le sous-sol peut également servir à stocker de la chaleur ou des gaz, par exemple de l’hydrogène ou du méthane, ou encore à enfouir de façon permanente du CO2. À cet effet, les mêmes exigences que pour l’extraction de chaleur doivent être vérifiées et le réservoir doit en outre être surmonté d’une couche étanche, empêchant le gaz de s’échapper. Le projet conjoint « Énergie hydroélectrique et géothermique » du PNR « Énergie » était avant tout consacré à la question de savoir où en Suisse trouver des couches de sol appropriées, répondant de manière optimale aux exigences des différentes utilisations. Un deuxième grand axe de recherche concernait les mesures visant à réduire la sismicité induite par les forages profonds et les dommages aux structures qui en résultent. Par ailleurs, des modèles et des simulations ont été élaborés dans le but de mieux comprendre les processus souterrains qui interviennent dans la mise en œuvre et l’exploitation des ressources géothermiques. En résumé, les résultats de recherche montrent que la Suisse jouit de bonnes conditions pour l’utilisation de la géothermie de moyenne profondeur (1-3 km), tant pour le parc de bâtiments que pour les processus industriels. L’optimisme est également de mise en ce qui concerne le stockage saisonnier de chaleur et de gaz. Le potentiel de stockage définitif de CO2 dans des quantités pertinentes s’avère en revanche plutôt limité. Concernant la production d’électricité à partir de la chaleur issue de la géothermie profonde (> 3 km), il n’existe pas encore de certitude définitive quant à l’importance du potentiel économiquement exploitable du sous-sol. Des installations de démonstration exploitées industriellement sont absolument nécessaires à cet égard, afin de renforcer l’acceptation par la population et les investisseurs.
