Facility Layout in Horizontal Cylindrical Space Based on Adaptive Gradient Descent Algorithm

FLP(Facility layout problem) is a common problem in engineering field. The past research tend to focus on the two-dimensional space and a small amount of three-dimensional box space as well as vertical cylinder space. The FLP in horizontal cylinder space is less researched. Lots of FLP of box space and vertical cylinder space can transform to FLP of two-dimensional space easily, however, the FLP of horizontal cylinder space need design special calculation method of overlap constraint and boundary constraint. This paper designed the calculation method of overlap constraint and boundary constraint, used adaptive gradient descent algorithm with heuristic strategy to optimize the facility layout in horizontal cylinder space. On this basis, added symmetry constraint, absolute height constraint and relative distance constraint to close to the real engineering demand. The experiment results confirm the feasible of proposed scheme.
