An integrated Model Proposal for the Selection of Lean Manufacturing Techniques

To survive in the harsh competitive environment, in addition to the efficient use of production resources, it is also important to reduce the wastes by identifying the reasons of wastes within the enterprise. The wastes that may be encountered in the lean manufacturing philosophy are collected under the heading of 7 wastes and called 7 Muda (overproduction, stock, inter-process movements, waiting, excessive processing, human-errors, in-process movements). In this study, a model proposal was introduced for an enterprise operating in Ankara which intends working in the framework of lean production, which aims to simplify production in its operation and wants to get rid of unnecessary activities. First of all; this study, which is accompanied by an expert who has knowledge about the internal dynamics of the business, prioritized waste items which will be used with the aim of simplifying the production of the business. Then to be used in lean production studies it has been decided to define the lean production techniques to be used in determining the root causes of these waste (Value Stream Map, Genchi Genbetsu, 7 Quality Tools etc). For this two-stage integrated approach, the fuzzy AHP and the ELECTRE method were employed.
