Discrete Event Simulation of Cabinet Assembly at ABB Robotics and Discrete Automation

Sammanfattning: Planning of the optimised production system is an intricate task. The reason behind this is changing demand, variations, and other disturbances. The main purpose of this study the current performance in the existing production system and provide recommendations for optimising the production in order to accommodate a new product. Since, the addition of new products may lead to bottlenecks in the flow which affects the output performance. The bottlenecks would lead to ineffective results, while tying up the capital in the production downstream as inventory gets stagnated in the assembly lines. The performance evaluation is a tedious process however, the study probes into the use of flow simulation tool to analyse the production performance. In this thesis work, Discrete Event Simulation (DES) is utilised as a tool to examine the performance of the production systems and to determine the cost consuming areas. To achieve that, the production system is replicated as a functional model into the DES system with the appropriate logics and parameters, with the thorough understanding of the existing workflows. To supplement it, the data from the orders, resources, and parts are charted.In the later part, production flow is analysed with the additions of determined improvisations to understand the impact on the output. Later, investigations are performed to identify the challenges and applicable changes required to meet future output. As an outcome, the production system is restructured and optimised, thus getting an overview of the future production set up as a digital factory layout.
