Cost estimation model for building projects using case-based reasoning

The case-based reasoning (CBR) method can be an effective means of utilizing knowledge gained from past experiences to estimate cost in construction. It has also been observed that CBR can enhance the accuracy of construction cost estimates. However, there are challenges related to the process of retrieving knowledge and information that still need to be addressed. One challenge is the computation of similarity and another is the assignment of the attribute weight values. To address these challenges, this paper develops a CBR cost estimate model for building projects using a Euclidean distance concept and genetic algorithms. Consequently, it was found that this model can enhance the accuracy of cost estimation and act as a basis for further research on the fundamentals of the case-based reasoning method.Koo CW, 2010, INT J STRATEG PROP M, V14, P121, DOI 10.3846/ijspm.2010.10Qian Z, 2009, EUR T ELECTR POWER, V19, P518, DOI 10.1002/etep.240Chou JS, 2009, EXPERT SYST APPL, V36, P2947, DOI 10.1016/j.eswa.2008.01.025*KOR I CONSTR TECH, 2009, CONSTR COST IND JULDussart C, 2008, J EVAL CLIN PRACT, V14, P718, DOI 10.1111/j.1365-2753.2008.01071.xDogan SZ, 2008, J CONSTR ENG M ASCE, V134, P146, DOI 10.1061/(ASCE)0733-9364(2008)134:2(146)Dikmen I, 2007, AUTOMAT CONSTR, V17, P30, DOI 10.1016/j.autcon.2007.02.009Ryu HG, 2007, J COMPUT CIVIL ENG, V21, P410, DOI 10.1016/(ASCE)0887-3801(2007)21:6(410)An SH, 2007, BUILD ENVIRON, V42, P2573, DOI 10.1016/j.buildenv.2006.06.007Huang MJ, 2007, EXPERT SYST APPL, V32, P856, DOI 10.1016/j.eswa.2006.01.038JRADE A, 2007, J ARCHITECTURAL ENG, V13, P205, DOI DOI 10.1061/(ASCE)1076-0431(2007)13:4(205)ZHUANG ZY, 2007, EUR J OPER RES, V195, P662Ahn H, 2006, EXPERT SYST, V23, P290Dogan SZ, 2006, J CONSTR ENG M ASCE, V132, P1092, DOI 10.1061/(ASCE)0733-9364(2006)132:10(1092)Chua DKH, 2006, J COMPUT CIVIL ENG, V20, P339, DOI 10.1061/(ASCE)0887-3801(2006)20:5(339)Ozorhon B, 2006, J CONSTR ENG M ASCE, V132, P940, DOI 10.1061/(ASCE)0733-9364(2006)132:9(940)Goh YM, 2010, J CONSTR ENG M ASCE, V136, P170, DOI 10.1061/(ASCE)CO.1943-7862.0000116Koo C, 2010, CAN J CIVIL ENG, V37, P739, DOI 10.1139/L10-007Funk P, 2006, COMPUT INTELL-US, V22, P238Park YJ, 2006, EXPERT SYST, V23, P2GOLDBERG DE, 2006, GENETIC ALGORITHMS SYI J, 2006, KOREAN J CONSTRUCTIO, V79, P128Han SG, 2005, EXPERT SYST APPL, V29, P573, DOI 10.1016/j.eswa.2005.04.026PAL SK, 2004, FDN SOFT CASE BASEDSun B, 2003, EXPERT SYST, V20, P92Morcous G, 2002, J COMPUT CIVIL ENG, V16, P104, DOI 10.1061/(ASCE)0887-3801(2002)16:2(104)Perner P, 2002, ENG APPL ARTIF INTEL, V15, P193KARSHENAS S, 2002, C COMP CIVIL ENG, P113, DOI DOI 10.1061/40652(2003)10STIFF JB, 2002, PERSUASIVE COMMUNICABurkhard HD, 2001, FUND INFORM, V47, P201Oberlender GD, 2001, J CONSTR ENG M ASCE, V127, P173Chua DKH, 2001, J CONSTR ENG M ASCE, V127, P35HENDRICKSON C, 2000, PROJECT MANAGEMENT C, V2ARDITI D, 1999, COMPUTER AIDED CIVIL, V14, P393, DOI DOI 10.1111/0885-9507.00157Liao TW, 1998, APPL ARTIF INTELL, V12, P267ELLSWORTH RK, 1998, COST ENG, V40, P27TAH JHM, 1998, ENG CONSTRUCTION ARC, V5, P327YAU NJ, 1998, COMPUT-AIDED CIV INF, V13, P143KRAFT DH, 1997, ADV FUZZY SYSTEMS AP, V7, P155LOPES HS, 1997, ADV FUZZY SYSTEMS AP, V7, P193MITCHELL TM, 1997, MACHINE LEARNINGSEELEY IH, 1997, QUANTITY SURVEYING PWATSON I, 1997, APPL CASE BASED REASSMITH AJ, 1995, ESTIMATING TENDERINGAAMODT A, 1994, AI COMMUN, V7, P35KOLODNER J, 1993, CASE BASED REASONING
