Dynamic Buffer Management for Raw Material Supply in the Footwear Industry

Abstract

In this paper, the application of inventory buffers is proposed as a management tool for the supply of raw material in the footwear industry. This allows to increase competitiveness and a significant decrease in investment in materials stored in the warehouses. This technique based on the holistic view will achieve the global optimum of the system giving importance to factors that prevent success of companies. In this sense, it is identified that the market demand is the systemś constraint for the development of the master production schedule. Considering this, it is necessary to concentrate all the materials in the central warehouse to establish an optimum inventory levels or buffers. Using a technique of colors materials ordering program is regularly reviewed through dynamic buffer management. As a result, the model improves the way how inventory of materials in the footwear industries is managed for resupply. Giving a priority to the materials low in stock. This generates 18,7 % of annual saving in inventory costs.  Index Terms-raw materials consumption, lead time, buffer, bill of materials, supply chain, priority

Dynamic TOC-based approach for planning and control of accessories in MTO environments

“…Leng & Yuxia [25] introduced three inventory control policies based on the DBM and used a simulation approach to compare them to the (s,S,T) policy. Reyes & Alvarez [26] proposed a model to manage the inventory by DBM. They used a technique of colours materials reviewed by DBM.…”

“…Constraints (24) and (25) show the service level of accessories considering the results of ABC analysis. Constraint (26) indicates the minimum value of net inventory to start production. Constraints (27) and (28) are as controlled constraints and M is a big number.…”

Dynamic bottleneck elimination in mattress manufacturing line using theory of constraints

“…Besides that determining the amount of buffer stocks are out of the scope of this study. On the other hand there are works such as Reyes et al (2015) which have been studied the sensitivity of buffer stock amount using TOC methodology.…”

Improved critical chain buffer management framework considering resource costs and schedule stability

“…The main advantages of CC/BM include its overall integration of activity durations, precedence relations and resource constraints, its explicit protection against stochastic variations under uncertainty by the use of aggregated time buffers and a set of reasonable control guidelines based on buffer monitoring (Trietsch and Baker 2012;Khemakhem and Chtourou 2013;Wang et al 2014;Zhang et al 2015b). Meanwhile, CC/BM has found its way towards practical applications in production systems in the manufacturing and service industries (Umble and Umble 2006;Kuo et al 2009;Reyes et al 2016).…”
