Abstract

As competition among industries increases in terms of quality, price, and flexibility, there is a need for industries to apply new advanced manufacturing philosophies, such as Lean Manufacturing (LM), for operational excellence in today's dynamic market. Manufacturing industries in Tanzania are now thinking of applying LM tools such as value stream mapping (VSM) to detect and eliminate waste in their production processes for improvements in their operations and the contribution of the manufacturing sector to the Gross Domestic Product (GDP) of the country, which stands at 8% as of date. This study applied VSM for one rice milling industry as a case study of food industries to identify nonvalue-added and value-added activities. The study comprised three phases, which were data collection from the industry, analysis of data, and mapping of actual and future state maps using the EdrawMax software version 10.5.0. Future state maps indicated that there would be significant improvements in the reduction of lead time by 44.3%, cycle time increase by 5%, increase in employee performance indicator from 88.3% to 91.7%, increase in quantitative production indicator from 82.8% to 90.5%, and increment of income generated after the elimination of identified activities which do not add value in their production operations. The study is beneficial for manufacturing owners and practitioners as it highlights how organizations can improve operational efficiency in terms of time reduction and an increase in income using VSM. The study recommends that the owners and practitioners of Tanzanian manufacturing industries and other developing countries should conduct VSM for each production process of their operations to improve the efficiency of their organizations and the contribution of the sector to the economy of the country.

提高发展中国家的制造业效率:坦桑尼亚碾米厂价值流映射案例研究
随着行业之间在质量、价格和灵活性方面的竞争加剧,行业需要应用新的先进制造理念,如精益制造(LM),以在当今动态的市场中实现卓越运营。坦桑尼亚的制造业目前正在考虑应用价值流图(VSM)等LM工具来检测和消除生产过程中的浪费,以改善其运营,并提高制造业对该国国内生产总值(GDP)的贡献,目前该国GDP为8%。本研究将VSM应用于一个碾米业作为食品行业的案例研究,以识别非增值和增值活动。该研究包括三个阶段,即从行业收集数据,分析数据,以及使用EdrawMax软件版本10.5.0绘制实际和未来的州地图。未来的状态图表明,交货时间减少44.3%,周期时间增加5%,员工绩效指标从88.3%增加到91.7%,定量生产指标从82.8%增加到90.5%,以及消除已确定的不增加生产价值的活动后产生的收入增加。该研究对制造业主和从业者是有益的,因为它强调了组织如何使用VSM在减少时间和增加收入方面提高运营效率。该研究建议坦桑尼亚和其他发展中国家制造业的所有者和从业人员对其业务的每个生产过程进行VSM,以提高其组织的效率和该部门对国家经济的贡献。
