A stochastic model to determine the elements of production cycle time in textile industry in Serbia

Abstract

This paper presents a model for the stochastic determination of the elements of production cycle time is proposed and experimentally verified in this survey. The originality of the model is reflected in the idea of using a work sampling model to monitor the production cycle, as one of the most significant indicators of production effectiveness and efficiency, instead of applying classical methods. Based on experimental investigations in this paper has been proved that in the practice of small and medium-sized enterprises with serial production it is possible to design and apply a very simple but accurate enough stochastic model to determine the elements of working cycle time and in this way optimize the duration of production cycle time. Proposed stochastic model uses mean value calculations to establish control limits on 3 standard deviations for the individual elements of working time and thus to master the process. It is proposed that further investigations should focus on the application and testing of the model in other types of production, for example, assembly and the like and also at the problem of reducing the elements of transport time. The model was applied and involved a larger number of Serbian enterprises. The results obtained for two characteristic textile enterprises will be presented in this paper.
