Abstract [en]

Abstract Together with reuse and material recycling, remanufacturing has emerged as a sustainable approach for used products. Remanufacturing is more complex than manufacturing, due to the uncertainties in material and information flows inside the remanufacturing facility and along the product life-cycle. Therefore, some remanufacturers intend to use lean production principles and philosophies to deal with this complexity and to improve their operations. The aim of this paper is to identify reasons for possible material and information flow uncertainties and develop lean-inspired solution at a German engine remanufacturer. The empirical data were collected via a Material and Information Flow Analysis workshop. The reasons for missing, late, defective and non-available spare parts as well as disrupted, uneven, chaotic and inaccessible information flows are identified. Finally, a lean pull Kanban reordering system is suggested and recognized to be a proper solution to remanufacturing complexity.

Abstract [en]

Remanufacturing is an environmentally sound material recovery option which is essential to compete for sustainable manufacturing. The aim with remanufacturing at a majority of companies is to prolong physical product performance by delivering the same or betterthan-original product quality. In general, remanufacturing is an industrial process that brings used products back to useful life by requiring less effort than is demanded by the initial production process. Consequently, from a product life-cycle perspective, remanufacturing generates great product value.

Remanufacturers lag behind manufacturers since they often face complex and unpredictable material and information flows. Based on a review of remanufacturing research, remanufacturing challenges in material and information flows can be classified into three groups: insufficient product quality, long and unstable process lead times, and an unpredictable level of inventory. While some remanufacturing researchers state that manufacturing and remanufacturing are significantly different, they have more in common than many other processes operations. Therefore, to sustain competitive remanufacturing, companies investigate an opportunity for improvement through the employment of lean production that generates significant benefits for manufacturers.

In order to investigate the potential to address remanufacturing challenges by lean production, a Minimum time for material and information flow analysis (MiniMifa) method was developed. This method originates from the value stream mapping (VSM) method, broadly practiced to bring lean to manufacturing companies. The focus of MiniMifa was to collect empirical data on the identified groups of remanufacturing challenges from the remanufacturing perspective, and to provide a basis for the development of improvements originating from lean principles.

Lean production was selected for this research due to its system perspective on material and information flows. Among the defined lean principles in remanufacturing, a pull principle was investigated at the case companies. The suggested principle demonstrated a reduction in lead time, followed by improvements in inventory level and product quality. However, in order to become lean, remanufacturers have to overcome three levels of lean remanufacturing challenges: external and internal challenges as well as lean wastes.

Finally, this research reduces the gap between academia and industry by contributing with a possible solution to the identified remanufacturing challenges in material and information flows.
