However, the global B-spline approximation, which is simply reduced to Bezier approximation of any degree p with C0 continuity, has led to the use of B-spline basis of high order in order to achieve high accuracy. The need for B-spline bases of high order in the global method would be more prominent in domains of large dimension. For the increased collocation points, it may also lead to the ill-conditioning problem. In this study, overlapping domain decomposition of multiplicative Schwarz algorithm is combined with the global method. Our objective is two-fold that improving the accuracy with the combination technique, and also investigating influence of the combination technique to the employed B-spline basis orders with respect to the obtained accuracy. It was shown that the combination method produced higher accuracy with the B-spline basis of much lower order than that needed in implementation of the initial method. Hence, the approximation stability of the B-spline collocation method was also increased. {\^A}{\copyright} IOP Publishing Ltd 2013.}, issn = {17426588}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-84876832081&doi=10.1088\%2f1742-6596\%2f423\%2f1\%2f012012&partnerID=40&md5=777071f6ebbf85de25a179786314c3a9}, author = {Hidayat, M.
