Análise de como puxar a produção em canteiros repetitivos planejados com linha de balanço

Abstract

Lean construction and line of balance programming are well established practices among leading construction companies. However, pull mechanisms, one of the major concepts that might associate line of balance to lean concepts, are not dealt with by academic literature on site programming of works. Pull concentrates in material supply according to examples that were found in the lean construction literature review. As construction sites do not have an assembly line to make it straightforward to establish pulling mechanisms, from suceeding activities to the preceeding ones, there is a need to emulate a production chain through the use of line of balance. This research work present different examples of line of balance programmes of work that would allow the determination of activities that might be pulled and the ones that necessarily must be pushed. Buffers between activities play a central role in determining the percentage of activities that preferably might be conducted according to the pull lean principle. Results are presented through the use of an Excel spreadsheet what allows to illustrate major findings in graphical terms.
