Scheduling Based Decision Support System Design for Determining the Number of Setup Workers Under SMED Environment

Abstract

<title>Abstract</title> <p>In industrial manufacturing systems, high profit achievement aim considers financial performance under the use of scarce resources and limiting wastes require a systematic approach lean method. Inventory cost, idle time cost, material cost, rework cost rise with large-lot production and work pieces. Achieving economic lot requires setup activity effect. Setup activity effect consists of setup activity time. Setup activity time is production time of previous setup activity exact product to successive setup activity exact product. Manufacturing difficulties of many enterprises push them to demand lean manufacturing tools and develop new ways. Cellular manufacturing, Value stream mapping (VSM), Total productive maintenance (TPM) and Single minute exchange of dies (SMED) are vital lean manufacturing tools to separate Non-value added activities (NVA) and Value added activities (VA), and eliminate wastes. Many studies examined the first four lean manufacturing tool. In this study, scheduling of set-up tasks on SMED environment proposes to examine lead time reduction, lean production method and scheduling setup tasks of setup activity. Continuous improvement encourages setup workers and operators to involve frequent improvement. In the case of yarn processing, setup activity and setup task of machine assigned for jobs to reduce raw material and processing time waste.</p>
