Modelling Dynamic Production Systems with a Special Focus on Dynamic Bottlenecks
نویسنده
چکیده
Bottlenecks play the key role in determining overall performance of manufacturing systems. Improving the performance of bottlenecks may lead to low inventory, appropriate utilization, short lead time and low schedule deviation. Therefore, consideration of bottlenecks is of prime importance at all levels of decision-making in production management practice (e.g. Production Planning and Control) and even in decision-making for strategic investments (e.g. process improving projects, new facility purchases, etc). Although bottlenecks have been a subject of study for more than ten years, current work still produces promising results; especially new and enhanced features for bottleneck-oriented Production Planning and Control methods are still required. The bottlenecks of a system may vary from different perspectives. From the view of logistical objectives in manufacturing, bottlenecks are categorised into inventory, utilization, lead time and schedule deviation bottlenecks. In terms of research subjects, bottlenecks can also be classified into resource, order and product bottleneck. Based on the bottleneck appearance cycle, we can categorize bottlenecks into static and dynamic bottlenecks. From the point of view of production logistics, several shortcomings of conventional bottleneck research have been pointed out.

Rapid urban growth is resulting into increase in travel demand and private vehicle ownership in urban areas. In the present scenario the existing infrastructure has failed to match the demand that leads to traffic congestion, vehicular pollution and accidents. With traffic congestion augmentation on the road, delay of commuters has increased and reliability of road network has decreased. Four s...

This study aimed at presenting a method for formulating optimal production, repair and replacement policies. The system was based on the production rate of defective parts and machine repairs and then was set up to optimize maintenance activities and related costs. The machine is either repaired or replaced. The machine is changed completely in the replacement process, but the productio...

This paper deals with the problem of optimizing two-stage structure decision making units (DMUs) where the activity and the performance of two-stage DMU in one period effect on its efficiency in the next period. To evaluate such systems the effect of activities in one period on ones in the next term must be considered. To do so, we propose a dynamic DEA approach to measure the performance of su...

Bottlenecks, as the key ingredients for improving the performances of the production networks, have been profoundly studied. However, the major definitions of bottlenecks are derived in terms of the throughput and based on the Theory of Constraints (TOC). Moreover, before the specific measures can be applied on them, it is not straightforward to localise dynamic bottlenecks due to their complex...
