Workplace layout design: a study of information exchange in virtual manufacturing

Abstract [en]

The concept of Virtual Manufacturing (VM) covers a wide scope of computerised manufacturing techniques, e.g. flow simulations and off-line programming. The tools can be from simple Excel sheets to complex specialist tools. The department of virtual manufacturing at Volvo Trucks develops methods to utilise these techniques in the best way. One important part in the future manufacturing of a truck is the surrounding industrial environment, the workplace layout design, that is the focus in this master thesis work. The goal is to find a well functional method of work regarding workplace layout design (WLD) that includes the surrounding layout, products, fixtures and tools. This means that data of different formats must be utilised in one software since the best layout and product software at the moment differs (FactoryCAD and Catia V5). An investigation of neutral formats has been made to solve the conversion question. Besides these technical studies are also examinations made over who will use the WLD in the future and what amount of responsibility shall be put on the users. This is made through interviews with people affected by the WLD, study of the required analysis possibilities and of what software shall be used in which purpose. The result of the master thesis work is that the digital mock-up tools are better suited to handle workplace layout design than FactoryCAD. But the methodology of the solution implies that the fundamental layouts are made in FactoryCAD and includes plant items, such as floors, walls and pillars and other factory items that are difficult to move, e.g. electric, water and ventilation piping. After the layout is imported to a digital mock-up tool (DMU Navigator) can the rest of the workplace be furnished, that is, the workplace layout will be made and stored in DMU Navigator. The method engineers are the one that will be the most frequent user of the WLD methodology. They will make the final design of the station and keep it updated. When more complex analysis is needed, e.g. ergonomic simulations, will a specialists be summoned. A number of interviews were made with Volvo Trucks employees that are involved in the virtual manufacturing development. The reason was to get a better understanding of the knowledge and attitude of the surrounding Volvo Trucks employees in the area. Interviews were also made with VM responsible at Volvo Cars, Volvo Powertrain and SAAB Automobiles, in order to get ideas about how good organisations that support virtual manufacturing work may look like. These interview series gives another view of the virtual manufacturing tool than the one of the department of VM. The Volvo Trucks employee sees that the visualisation possibilities are most interesting in the VM use and the interview with companies outside the Volvo Trucks shows the big problem of introducing these tools in the rest of the organisation. A conclusion of the interviews is that the introduction of the VM tools will take place and must take the time it needs, but will never take place without stresses and guidance from the persons in charge.
