Improving customer satisfaction is important in order to create a good relationship between a company and its customers which will give benefit to both sides. One way to accomplish it is by conducting quality improvement. Quality improvement has a strong relationship with the customer satisfaction, so it is an important issue in manufacturing. This paper discusses an optimization model to allocate...
We need energy resources to assure performance of mechatronic systems. The performance assurance is of major importance in present systems since it leads to high availability and capability. It also helps to reduce failure occurrence. In the article we want to find the up state time of Li-ion batteries. Results are related to influence of the operating environment at different climatic levels. We...
This paper proposes a state space model to describe multivariate autocorrelated zero-inflated count series. The model extends the classical zero-inflated Poisson distribution into multivariate cases but is able to impose different zero inflations on different dimensions. Combing the zero inflation with the log-normal mixture of independent Poisson distribution, this model allows for flexible cross-correlations...
Failure boundaries are always far away from the center of the design space of variables for low failure probability problems. In order to make full use of samples, a partitioning method of experimental levels is proposed for improving general design of experiments in this paper. The method is implemented by non-uniformly partitioning experimental levels according to the probability density function...
In equipment joint support, support tasks generated by different equipment share the resource of the support sites. Compared to conventional support system, more categories of support objects leads to a sharp increase in the number and randomness of support tasks. This makes the progress of some support activities affected by the resource occupation of other activities. In other words, the availability...
