Computer aided factory layout planning (CAFLAP)Kobliha, Bohumil Augustin January 1988 (has links)
This Thesis addresses Factory Layout Problems, and reviews and evaluates the available layout techniques. Manufacturing as a system has been studied and reclassified for factory layout: space demands and spatial relationships have been considered as main principles of Factory Layout Planning. This forms a basis for the introduction of a new, more efficient Factory Layout Planning Methodology, denoted as SPACE MANAGEMENT. A new COMPUTER AIDED FACTORY LAYOUT PLANNING system is formulated as a tool for: - preparing 3-D templates of Work Station Modules and Equipment Modules; - drawing a requested interior of an industrial hall/bay in 3-D; - positioning any 'objects1 (spaces), via manual interactive programs i n 3-D; - automatic positioning of work stations and equipment in the bay, in 'technological' order (in 3-D), using an automatic positioning program, with a facility for: collision course finding(with objects within the bay), manual override for corrections, and finding an optimum size (width) of the bay. The resulting layout scene can be observed from any required Position and distance. The system includes a set of auxiliary programs for Manual Feeding of lines of work stations in 'technological' order and for basic capacity calculations. CAFLAP also opens a new way of economic evaluation of Projects and alternatives. CAFLAP is implemented in FORTRAN 77 and uses the Computer Graphics System PICASO.

Hur fabriksflöden kan visualiseras med hjälp av Unreal EngineBergström, Emmy, Lundberg, Robert January 2023 (has links)
Virtual Reality (VR) is a tool with great potential and is under constant development for use in new fields. The project Fabriksvisualisering (Factory Visualization), has within the digital factory field, developed a tool for companies to build their factories in Unreal Engine (UE) and VR. The tool gives companies the opportunity to test their factory layouts, before implementing in the real world, to avoid costly mistakes. The following report examines possibilities for users to simulate and visualize their factory workflows as a part of the project Fabriksvisualisering. To achieve this, different solutions for visualizing the flow of products, staff and vehicles have been explored. User tests were carried out to test how an effect from UE can be used to visualize a flow of products in VR. The result gives users the opportunity to experience the interactions with factory workflows and visualize how they flow in VR. The project resulted in two options that visualizes product flow and four options that visualizes workflow. Out of these six solutions, three were chosen and implemented to the project Fabriksvisualisering. These solutions are based on the construction of splines and include both alternatives for product flows and one alternative for workflows. The selection was based on functionality, user-friendliness and how realistic the outcome is. The result gives users the opportunity to experience the interactions with factory workflows and visualize how they flow in VR. The conclusion is that there are several ways to visualize four out of seven factory workflows. The flows that are possible to visualize are material handling of raw materials, semi-finished and finished products, as well as the transportation and movements of workforce. This can be visualized with the help of AI, a robot system within UE, the construction of splines and Niagara systems connected to splines.
