Statistical control of mutual exchange of details (tenon -mortise ) from beechwood, in some of manufacturing factories of chairs in region of Ferizaj

Abstract

Like every manufacturing industry, the wood industry also faces with many challenges. For responding to these challenges, companies need to improve constantly the quality of their products, by using scientific analysis and putting them into use. This study presents statistical process control of the elements of tenon and mortise, based on data analysis, obtained from production. Based on data processing, the conclusions are given by regarding the possibility of cooperation of companies and their mutual exchange. The regular application of control charts, reduces defects and production costs, and keeps open possibilities for collaboration between enterprises, by exchanging certain parts (concrete case “parts of furniture from wood”). The aim of the study, are the possibilities of mutual exchange of parts produced at different factories and the possibility of collecting these elements in a certain place, where could be conducted only the joining process. The subject of the study were three different companies for the production of chairs, in region of Ferizaj, which use the same raw material, but use different types of machinery.
