However, lean operations depend on level scheduling and the growing need to accommodate variety and demand uncertainty has resulted in the emergence of the concept of agility. This paper explores the role of inventory and capacity in accommodating such variation and identiï ¬ es how TRIZ separation principles and TOC tools may be combined in the†¦show more content†¦More recently lean manufacturing (Womack et al., 1990) and lean thinking (Womack and Jones, 1996) have demonstrated the broad potential of the elimination of waste in improving business performance. The emphasis on waste elimination is closely associated with reduced inventory and one of the key concepts is enforced problem solving, which is very effectively portrayed by the ubiquitous ship and rocks analogy. In the analogy as the inventory (water level) is lowered, the sources o f waste (the rocks) are exposed in the form of late delivery, poor quality conformance, long set-ups, unreliable processes, etc. The elimination of these sources of waste and unevenness enables the inventory to be lowered further without impeding material ï ¬â€šow (the ship). The JIT management system was found to simultaneously improve customer service and efï ¬ ciency by focus- ing on eliminating variation in the system and enabling ï ¬â€šow. Through set-up time reduction, statistical process control, supplier development, total productive maintenance, etc., sources of variation internal to the supply chain were progressively reduced, so reducing the need for the inventory previously used to protect the ï ¬â€šow. For this design of delivery system to work well it is also necessary to stabilize the overall output rate and so decouple the effect of market demand variation. This is commonly achieved by what is termed ‘level scheduling’ and someShow MoreRelatedLean The Lean Supply Chain Management1552 Words   |  7 PagesLean Management Approach In modern day world, organizations are facing a myriad of challenges. They are facing increasing and continually changing demands by customers, keen and knowledgeable competitors who seize every opportunity that comes their way, and a reduction of the resource base owing to increase spending.

Supply chain management focuses on managing the supply chain in an effort to improve the quality and time it requires to manufacture a product. In addition to implementing supply chain management, a helpful lean production practice called Just-in-time can be used to remove any waste present along the supply chain. The marriage of lean production and supply chain management creates lean supply chain management, which provides a much leaner and more economical supply chain forRead MoreSupply Chain Management And Lean Manufacturing1789 Words   |  8 Pages Supply Chain Management and Lean Manufacturing and its Influence on Operational Performance. ABSTRACT The first paper develops its idea based on previous research that was carried out by Frohlich and Westbrook that distinguishes the influence being played by supply chain integration on the performance of certain firms. This paper provides an overview of how manufacturing firms arbitrate the relationship their supply chain integration and its respective business performance.

When you have a complex supply chain, supplier evaluation and reduction is a great step that can be taken towards having a lean supply chain. Supplier evaluation and reduction is a continuous process within organizations and forms part of the pre-qualification step within the supply chain management process, although in many organizations it includes the participation and input of other departments and stakeholders. Most organizations experienced in collecting supplier evaluation information preferRea d MoreAgile and Lean Supply Chain Management1719 Words   |  7 Pagesvolatile marketplace. Leagile is the combination of the lean and agile paradigms within a total supply chain strategy by positioning the decoupling point so as to best suit the need for responding to a volatile demand downstream yet providing level scheduling upstream from the marketplace. The decoupling point separates the part of the organisation (supply chain) oriented towards customer orders from the part of the organisation (supply chain) based on planning.
