Modeling Spare Parts Demands Forecast under Two-Dimensional Preventive Maintenance Policy ×÷Õß:Hu, QW (Hu, Qiwei)[ 1 ] ; Bai, YS (Bai, Yongsheng)[ 1 ] ; Zhao, JM (Zhao, Jianmin)[ 1 ] ; Cao, WB (Cao, Wenbin)[ 1 ] MATHEMATICAL PROBLEMS IN ENGINEERING ÎÄÏ׺Å: 728241 DOI: 10.1155/2015/728241 ³ö°æÄê: 2015 ²é¿´ÆÚ¿¯ÐÅÏ¢ ÕªÒª In maintenance practice, there is such a situation where the spare parts replacement should be carried out at the scheduling time of calendar or usage for whichever comes first. The issue of two-dimensional preventive maintenance usually was not addressed by traditional methods, and at present, few studies were focused on this very topic. Based on these considerations, this paper presented the two-dimensional preventive policy where replacements of spare parts are based on both calendar time and usage time. A novel model was developed to forecast spare parts demands under two-dimensional preventive maintenance policy, and a discrete algorithm was presented for solving the mathematical model. A case study was given to demonstrate its applicability and validity, and it was showed that the presented model can be used to forecast spare parts demands as well as to optimize spare parts and preventive maintenance jointly. ¹Ø¼ü´Ê KeyWords Plus:ITEM INVENTORY SYSTEM; JOINT OPTIMIZATION; WARRANTY COST; TIME SCALES; USAGE RATE; REPAIR; REPLACEMENT; LEVEL ×÷ÕßÐÅÏ¢ ͨѶ×÷ÕßµØÖ·: Hu, QW (ͨѶ×÷Õß) Mech Engn Coll, Dept Engn Management, Shijiazhuang 050003, Peoples R China. µØÖ·: [ 1 ] Mech Engn Coll, Dept Engn Management, Shijiazhuang 050003, Peoples R China µç×ÓÓʼþµØÖ·:h_q_w@sina.com ³ö°æÉÌ HINDAWI PUBLISHING CORPORATION, 410 PARK AVENUE, 15TH FLOOR, #287 PMB, NEW YORK, NY 10022 USA Àà±ð / ·ÖÀà Ñо¿·½Ïò:Engineering; Mathematics Web of Science Àà±ð:Engineering, Multidisciplinary; Mathematics, Interdisciplinary Applications ÎÄÏ×ÐÅÏ¢ ÎÄÏ×ÀàÐÍ:Article ÓïÖÖ:English Èë²ØºÅ: WOS:000350579100001 ISSN: 1024-123X eISSN: 1563-5147 ÆÚ¿¯ÐÅÏ¢ Impact Factor (Ó°ÏìÒò×Ó): Journal Citation Reports® ÆäËûÐÅÏ¢ IDS ºÅ: CC7WM Web of Science ºËÐĺϼ¯ÖÐµÄ "ÒýÓõIJο¼ÎÄÏ×": 33 Web of Science ºËÐĺϼ¯ÖÐµÄ "±»ÒýƵ´Î": 0 |
