Build-to-order was once the only way in which products were made, but limited the market to only the rich buyers. Mass production contributed to a wider access to products, however with losses in individuality. Finally, mass customization aimed at holding out the promise of both, and “lean” concepts helped to (partly) make it a reality. However, the world has changed significantly since the first introduction of “lean” – especially in the most recent years. European companies are facing a growing international competition in volume markets due to the increasing economical and technical emancipation of low labour cost countries. While multinational enterprises are shifting their manufacturing activities to Far East to keep competitive in terms of costs, small and medium sized companies often have to leave their traditional market segments and retreat into niches. However, smaller production lot sizes and the increasing complexity of product programmes require innovative manufacturing strategies. According to several studies and empirical proves, less than 0,5% of a company’s production lead time is value adding, the bigger part of it is dedicated to waiting, handling and internal transport. This paper presents a new approach for the design of lean manufacturing support systems in make-to-order production systems that have to deal with a huge variety of product types and with high variations in demand. A special focus is given to the design of manual material handling and transport (MMHT) solutions. With the help of axiomatic design principles, a tree of design parameters is derived and translated into generally applicable design rules. With the help of a practical example from make-to-order industry, the validity of the methodology is illustrated.

Production is the main thing in a manufacturing industry. Production activity would work well if the flow pattern of the material in the production floor smoothly. Better transfer of material will speed up the completion of a product. Intense competition in the manufacturing industry forced the industry to make the material flow to be short. This can be done by resetting the engine layout in such a way. Industry Furniture X as one of the furniture industry in the city of Palembang that manufacture products based on the make to order. The product has so many variations of high material flow and higher material handling costs. The distance between the machines far enough too play a role in the cost of material handling.The layout of the fractal method can produce a short distance between the machine and more flexible to address the varying conditions of the product. This method will form fractals that have the same ability to make the production process, in which fractal is formed of two pieces, each of which consists of 9 pieces of machinery . In the proposed layout is formed , the machines were experiencing engine displacement is 1A , 1B , 1C , 2B , 3B , 4 , 5 , 6A , 6B , 7 ,8A, 8B, 10A, and 10B. This method was successful in reducing the material displacement distance during research periode of 58,125 meter or 6.251% and the cost of material movement during research periode Rp 27.971,9375 and during one year Rp 559.438,75 or 3,066 %.

Purpose – Workload control (WLC) is a Production Planning and Control concept of particular relevance to small and medium sized make-to-order companies. Despite the simplicity of its core principles, few successful implementations have been reported, and both understanding and awareness of the concept amongst practitioners is limited. The authors describe a rare successful implementation of WLC in which elements of the concept were embedded in a company to support both customer enquiry management and order release. The purpose of this paper is to focus on the implementation process itself rather than the impact on performance. Design/methodology/approach – A particularly novel aspect of the case is that the implementation was practitioner (rather than researcher) led. A manager chose to read up on and implement the concept, creating a strong in-house commitment to the initiative. The researchers played a facilitating role, e.g. intervening where necessary to answer questions and advise. A factory visit/tour and interview were also conducted post implementation to reflect on the process. Findings – The authors identify the elements of WLC implemented by the practitioner and how they were refined to meet company requirements, with implications for improving the alignment between theory and practice. The paper also informs the implementation process, for example, by highlighting the importance of managerial championing for implementation success and how WLC can be implemented based on a reasonably simple Excel© spreadsheet. Research limitations/implications – More empirical evidence is required to assess the generality of some of the adaptations made by the practitioner; and to collect longitudinal quantitative evidence on the performance of WLC over time. Simulations could also be conducted to confirm the effectiveness of adaptations observed in the study. Practical implications – The case has implications for the process of implementing WLC and may provoke a rethink in terms of the range of companies for which the concept is thought to be appropriate – the case described is of a larger, higher volume company than most previous WLC implementations. Originality/value – A rare case of a successful implementation of WLC at both the customer enquiry management and order release levels; the only practitioner-led implementation of WLC reported in the literature to date.
