Abstract
The planning of new factories, as well as the re-planning of existing factories, has become more frequent due to increasingly changing business requirements, as for example shorter product life cycles and Industry 4.0. A higher number of involved planners and the resulting high amount of planning information strongly require coordination. In this context, the importance of Building Information Modeling (BIM) in factory planning rises as it provides a method of integrated building planning and planning validation by means of 3D software and object-oriented modelling. However, despite the use of BIM, there are still major interface problems in factory planning that cannot be solved by the still manual plausibility checks of non-geometrical planning information. To enable automatic checking of planning results, thereby improving the BIM-based factory planning process, machine-readable explication of the parametric dependencies are required between different planning fields such as production planning and building planning. The goal of this paper is to show parametric and thus non-geometric dependencies that exist between the sub-models of BIM-based factory planning in such a way that software agents can automatically evaluate this design information. Within the planning interface between production planning and building planning, the paper focusses on the particular exchange between the planning of the manufacturing system and the planning of a cutting fluid pump. With the involvement of domain experts from factory planning, systems engineering and production engineering, we as the authors have managed to develop a coherent system of block diagrams, constraint diagrams and parametric diagrams that explicate the focused interface in a machine-readable manner. We believe our accomplishments are an essential element for completely automated planning validation in BIM-based factory planning and general object-oriented modelling in the future.
Highlights
The time and cost pressure of factory planning projects has considerably increased in recent years
[5] Structural and engine components of airplanes are produced by accurate manufacturing processes along with the applicable infeed of cutting fluid—the pump of which and all feed pipes are planned by the MEP planner or by a planning department of the pump supplier
The objective of the research study was to establish machinereadable parametric connections between manufacturing planning and MEP planning with a focus on cutting fluid in order to solve the problem of manually checking planning parameters in Building Information Modelling (BIM)-based factory planning
Summary
The time and cost pressure of factory planning projects has considerably increased in recent years. This can be explained by shorter product life cycles and the rising number of involved stakeholders in factory planning projects. Production Engineering (2021) 15:57–67 additional field of manufacturing systems planning. The number of planners rises, and the planning focus is shifted away from the building as the foremost goal of factory planning is the value-adding process. The planning of the factory and its value-adding processes directly depend on the product and the effort required to produce it. [5] Structural and engine components of airplanes are produced by accurate manufacturing processes along with the applicable infeed of cutting fluid—the pump of which and all feed pipes are planned by the MEP planner or by a planning department of the pump supplier. According to our experience, this task is often commissioned to MEP planners who carry out all pipeline and duct planning
