Methodical approach to increase productivity and reduce lead time in assembly and production-logistic processes

The introduced methodical approach connects Value Stream Mapping (VSM) and Methods-Time Measurement (MTM) and offers new distinct advantages to reduce lead time and increase productivity based on lean principles and standardised processes. The mutually aligned design and improvement of assembly and (production) logistic processes takes either the workplaces, their surroundings and the supply areas as well as the overall value chain into account. The identification and exploitation of productivity potentials is realised by the joint application of VSM and MTM focussing the (work) methods, the performance and the utilisation of the processes (the dimensions of productivity). ples, benefits and the procedure of application are described in the paper. A practical example highlights the redesign of assembly workplaces and the redesign of (production) logistic processes to reduce inventory/lead time using logistical and ergonomic aspects specially applying MTM logistic process elements.
