Nowadays, by successful application of on time production concept in other concepts like production management and storage, the need to complete the processing of jobs in their delivery time is considered a key issue in industrial environments. Unrelated parallel machines scheduling is a general mood of classic problems of parallel machines. In some of the applications of unrelated parallel mac...

The fourth industrial revolution is paving the way for Industrial Internet of Things applications where large number wireless nodes, equipped with sensors and actuators, monitor production cycle goods. This paper proposes analyses LoRaIN, a network architecture MAC-layer protocol thought on-demand monitoring machines. Our proprietary system an energy-efficient, reliable scalable solution, built...

In this paper, a new mathematical model for the problem of job scheduling in virtual manufacturing cells (VMC) is presented to minimizing the completion time of all jobs. Sequence dependent setup times of machines is considered and lot-streaming is possible. In Virtual manufacturing cells, each job has a different processing path and there is a set of machines for processing each operation. The...

The present investigation deals with a machine repair problem consisting of cold and warm standby machines. The machines are subject to breakdown and are repaired by the permanent repairman operating under N-policy. There is provision of one additional removable repairman who is called upon when the work load of failed machines crosses a certain threshold level and is removed as soon as the wor...

Abstract As a starting point in equipment manufacturing, sawing plays an important role industrial production. Intelligent manufacturing is carrier of intelligent technologies. Due to the backwardness technology, comprehensive performance equipments China obviously different from that foreign countries. State art advanced investigated along with technical bottleneck machine tool and new scheme ...

The authors outlined a model to examine the modern printing machines’ unexpected breakdowns. They had been analysing the different downtimes for years. The results of the researches help to organize the pro-active maintenance at the graphic arts industry.
