Timing analysis for ADAS Architectures

TNO is the world leader in truck platooning technology. This technology allows a group of trucks to become linked to each other, using data transmitted over radio communication, forming a virtual “vehicle train” driven by the front vehicle driver only (the other drivers become passengers).

The technology that enables truck platooning is called Cooperative Adaptive Cruise Control (CACC). To guarantee correct CACC it is important to accurately derive the data transmission latencies between trucks. The latency calculations should take into account not only the radio communication delays, but also the delays introduced by the data flowing from one component of the truck hardware platform to another. In this assignment, you will contribute to development of a systematic methodology to ascertain the worst-case-scenario end-to-end latencies together with its statistics, in a way that is modular and captures the shared resources interactions.

The assignment will give you the opportunity to get acquainted with real-life ADAS architectures, work in a dynamic environment on automated driving functions at TNO Helmond and to link the practical and theoretical aspects of timing analysis of ADAS architectures.

We want to investigate the impact of reconfiguration of the print head of a printer on productivity and quality. Stringent productivity targets force engineers to look at ways to improve productivity, without losing (too much) product quality. Reconfigurations during operation generally improve quality, but cost time and hence, productivity. On-line reconfiguration of a print head can sometimes be avoided by tolerating small deviations from the optimal configuration within an acceptable working range for a particular product.

In this assignment you will model the quality versus productivity trade-off that emerges from the scheduling freedom of the print head range. The first step is to model the quality and productivity depending on reconfiguration strategies, and define and study the trade-off space. The second step is to find the optimal trade-offs and scheduling strategies that lead to these trade-offs, for given specification ranges and sequences of sheets and their media types.

Modeling of Oce production printers as manufacturing systems

In this assignment we look at modeling the paper path of a large-scale production printer as a manufacturing system and optimizing the sheet schedules. Such a printer prints thousands of duplex images per day (e.g. books for Amazon), transaction printing (bank statements) on different media. The paper path of the printer is large enough to fit up to 100 sheets at the same time. As these sheets are to be printed on the front and the back by the same print head, the sheets printed once should be efficiently interleaved with unprinted sheets. The media and size of the paper may influence the minimum time between subsequent sheets at the print head, and the return loop needs to operate within a minimum and maximum speed.

To investigate the large-scale production printer in terms of timing and productivity, we propose to use a mathematical model that allows automated analysis and optimization of the manufacturing system. Recently, we have developed a formal modeling approach to model manufacturing systems. In this assignment, you will investigate the application of this approach to create a behavioral model of the large-scale production printer. This model needs to capture the timing aspects, and in which order, and when, the printer can execute certain tasks. This model can then be used to optimize the printing sequence. If certain aspects of the production printer cannot be captured using the current modeling approach, or cannot be analyzed with existing analysis methods, the approach needs to be extended.

Modeling component tolerances for paper path designs

The aim of this project is to include the tolerances of (transportation) components such as pinches, switches and belts into an existing optimization model. The model optimizes the paper path lengths and timing profiles for particular sequences of sheets through a direct transcription model. In this assignment you will extend the model by taking into account imperfections, and create a model that propagates the positional errors/skew to optimize timing profiles for sheets.

Performance Optimization by Playing Games

In this assignment you will look at performance optimization of production systems using game theory, the mathematical theory that deals with modeling of conflict and cooperation between intelligent rational decision-makers. Game theory is an active research area that has applications in many fields, such as economics, logic, psychology, computer science, and electrical engineer- ing. Game theory can also be used to optimize the performance of systems in an unpredictable or uncontrollable environment. In this case, the system controller is modeled as a player, and the environment is modeled as its opponent player. Synthesizing an optimal controller corresponds to finding a winning strategy for the controller player in terms of the game. There are games that can optimize for throughput, or try to prevent that unsafe system states are ever reached.

In this assignment, you will investigate existing games, and develop new games if needed, that can be used for performance analysis and optimization of systems. Because systems are often optimized for multiple criteria, and need to adhere to certain requirements, multi-objective optimization under constraints is part of the assignment. For instance, finding all controllers that satisfy a throughput bound, and then find the best one in terms of minimal latency and maximal energy efficiency.

Modeling and analysis of the workflow around wide format roll-to-roll Oce printers

In this assignment we look at modeling and analysis of the workflow around wide format roll- to-roll printers. Such a printer prints large images (posters, banners, etc) on different media. The operators have to change rolls (when a roll is empty or another media type is needed), to fill ink (ink handling can be done during print), and remove waste. Furthermore, the operator may have to perform preprocessing and offline postprocessing (for example laminating) on specific jobs. To some extent, the operator can reorder print jobs. To investigate the workflow in terms of timing and productivity, we propose to use a mathematical model that allows automated analysis and optimization of the workflow.

Visualization and analysis of data caching

Many embedded systems are data intensive. Examples include the video processing system in an interventional X-ray machine, and the processing of image data in the datapath of high-end printers. Often, these systems are implemented, at least partially, in software which runs on multi-core embedded platforms. Furthermore, there are strict performance requirements, e.g., on the throughput of the system. Clearly, the software implementation has significant impact on the system performance. One key aspect in these data-intensive systems is how the software implementation uses the hardware data caches. An actual assessment whether cache usage can be optimized and what its system-level performance benefits are, however, is difficult because it requires the user to gather detailed information from several sources through specialized tools (e.g., Intel VTune), and to manually combine information for the final interpretation. The goal of this assignment is to provide an integrated approach to the above-sketched problem based on execution traces of the system.

Multi-core Datapath Contention Modelling

The datapath is a central part of printers and copiers and is responsible for the image processing that is necessary to produce output of required quality. A key performance indicator of the datapath is its performance, typically expressed as throughput in processed image-data per minute. The operations in the datapath are data-intensive and are often implemented in software on multi-core embedded platforms. The programming can thus have a significant effect on the performance through its use of the data caches. Currently performance offered by platform components rapidly increases. The graduation assignment is to analyze and optimize the image processing in print datapaths for multi-core platforms shared with other software components, under the constraint that the image processing performance may not decrease, in order to guarantee sufficient throughput for the printer.

Productivity printer performance modeling

Assignment: Create and enhance models for predicting the performance of the production printers of Canon Océ. For all kinds of print shop optimization, such as workload planning, it is necessary to have a fast and accurate estimation of how much time a print job will need to execute. This problem is quite difficult due to the complex layout of the printer and the non-trivial scheduling problem.
