This method aims to reduce the sort of parts for cutting the manufacturing cost and for improving specifications of parts. Two linear mathematical programming models are proposed for standardizing the parts. One model aims at cutting cost half without causing any degradation of mechanical specifications of parts. The other model aims at doubling mechanical specifications of parts below the acceptable manufacturing cost. These models are formulated in 0-1 integer programming forms. The integer programming model shows which part is common to other parts. An example is shown to demonstrate the use of the developed method. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=DongLiu kn-aut-sei=Dong kn-aut-mei=Liu aut-affil-num=1 ORCID= en-aut-name=KajiharaYasuhiro en-aut-sei=Kajihara en-aut-mei=Yasuhiro kn-aut-name=īN kn-aut-sei=ī kn-aut-mei=N aut-affil-num=2 ORCID= en-aut-name=OsakiHirokazu en-aut-sei=Osaki en-aut-mei=Hirokazu kn-aut-name=åčhę kn-aut-sei=åč kn-aut-mei=hę aut-affil-num=3 ORCID= en-aut-name=MunesawaYoshiomi en-aut-sei=Munesawa en-aut-mei=Yoshiomi kn-aut-name=@āVĮb kn-aut-sei=@āV kn-aut-mei=Įb aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=Department of Mechanical Engineering affil-num=2 en-affil= kn-affil=Department of Mechanical Engineering affil-num=3 en-affil= kn-affil=Department of Mechanical Engineering affil-num=4 en-affil= kn-affil=Department of Mechanical Engineering END
