Sentence examples for machine service rate from inspiring English sources

We have developed a stochastic CMS model that considers the arrival rate of parts into cells and machine service rate as uncertain parameters.

This paper presents a non-linear mixed integer programming model to design cellular manufacturing systems which assumes that the arrival rate of parts into cells and machine service rate are stochastic parameters and described by exponential distribution.

Fardis et al. (2013) examined the CF problem considering that the arrival rate of parts into cells and machine service rate are stochastic parameters, which have described by an exponential distribution.

This paper proposes a mathematical programming approach to construct the membership function of the performance measure of the machine interference system with the machine breakdown rate and the service rate being fuzzy numbers.

( mu_{j} ) mean service rate for machine j (mean number of customers served per unit time by machine j).

They assumed parts as customers and machines as servers, in which the arrival rate of parts and service rate of machines were identified by the exponential distribution.

λ i   Mean arrival rate for part i.  μ j   Mean service rate for machine j.

hfill &lambda_{text{d}} :,{text{Degraded failure rate of machines}}.hfill &mu_{i} : {text{ Mean service rate of }}i{th} (i = 1,,2 ) {text{ server}} hfill &alpha_{i} : {text{ The life time of }}i{th} (i = 1,,2 ) {text{server}}.hfill &beta_{i} :,{text{Repair rate of }}i{th} (i = 1,, 2 ) {text{server}}.hfill end{aligned}.

In this section, a stochastic cellular manufacturing system problem will be formulated as a queue system, which considers parts and machines as customers and servers with the arrival and service rate of λ and μ, respectively.

In a steady system, to avoid infinite growth of queue, the service rate must be greater than the arrival rate, so the utilization factor (probability of being busy) of each machine will be less than 1.

The effects of the failure rates of operating machines (λ, λ d), the failure rate of spares, service rates (µ, µ a) of the repairmen and the number of operating machines (M) have been examined on various performance measures such as the expectation E(n) and variance Var(n) of the number of failed machines in the system, throughput and the expected total cost E{TC} incurred on the system.
