Computerization of spin plan and determination of labour norm at ring frame considering the net loss recovery through piecing up the broken ends of yarn

Abstract

Bangladesh IS one of the lest developed countries llnd its textile sector has been declared as "thrust sector" for industrial development. Creation of necessary backward linkage by establishing sophisticated spinning mill is the precondition to achieve the economic goals through developing the Textile Sector. End down or end breakage is one of the major problems that reduces production and increases labour cost of spinning mills. End breakage is an unavoidable phenomena during spinning and accordingly a number of manpower is engaged to eliminate end breakage by piecing up the broken ends. The number of side(s) to be allocated per tenter (labour) at any end breakage rate has been introduced in spin plan (determination of optimal number of machines and accessories in all sections of spinning mi 11) • Spin plan is an essential but laborious and time consuming task. To overcome the constraints a computeri:;:ed method has been developed for spin plan which requires least time to provide almost all required features. A table has been prepared under the title "Ring Production Table (RPT)"' containing some essential techno-managerial indexes and instantaneous vivid features of ring production data and also shows among others (interalia) the optimal labour norm against the ring frames, revenue generation per day etc.
