The effectiveness of a proposed method to solve the design problem (a modified dual-affine scaling variant of Karmarkar's (1989) algorithm and an approximation scheme) is illustrated through several design examples.journal article10.1109/78.7353002-s2.0-0032304680https://www.scopus.com/inward/record.uri?eid=2-s2.0-0032304680&doi=10.1109%2f78.735300&partnerID=40&md5=90b0fe794fc1ee40300ee08acf20547b
