To improve research efficiency of engineering problems, Surrogate model has gained its popularity in replacing real engineering model. This paper proposes a kind of Global Sequential Sampling Algorithm (GSSA) based on surrogate model. With the process of iteration, GSSA can sample both in unexplored region and large-error region, then iteratively update the samples. OLHS is used as initial sampling...
Assembly Sequence Planning (ASP) is a NP-hard combinatorial problem. In order to reduce computational complexity, this paper proposes a novel assembly sequence planning approach based on Graduated NonConvexity and Concavity Procedure (GNCPP), a general optimization framework which approximately solve the combinatorial optimization problems defined on the set of partial permutation matrices. The mathematical...
Facility layout problem which deals with the placement of facilities in the plant area is one of the most critical problems in manufacturing systems design. However the facility layout problem is one of the combinatorial optimization and nondeterministic polynomial complete problems, and obtaining an optimal solution for the large-sized facility layout problem in reasonable computational time using...
