Sentence examples for pm activities from inspiring English sources
This study deals with the problem of scheduling jobs and preventive maintenance (PM) activities in production workshops jointly in order to reduce failure occurrence.
PM activities can be planned at fixed periods (time-based PM) or in response to a signal provided from a machine's captor after anomaly detection (condition-based PM).
In the fixed policies, PM activities are performing exactly pre-specified time intervals while in the conservative policies, whenever production and PM activities have overlap the production operation is postponed and PM activities are conducted first (Jolai et al. 2009).
This study, adopt the modelling framework proposed by Kim et al. (2004) to model the effect of PM activities.
Manufacturers should only perform PM actions when the cost savings of warranty servicing exceeds the additional cost incurred by performing PM activities.
Usually, a PM activities involve a set of maintenance tasks, such as, cleaning, systematic inspection, lubricating, adjusting and calibrating, replacing different components, etc. (Ben Mabrouk et al. 2016).
The colocalization of receptors for Pg and its activators restricts plasmin (Pm) activity to specific sites and serves to promote fibrinolysis and local Pg activation.
v j : Virtual remaining life after performing the jth PM activity.
Therefore, the virtual remaining life after performing the jth PM activity, i.e. RLj, is then given by v_{j} = v_{j - 1} + delta (m)({text{RL}}_{j} - {text{RL}}_{j - 1} ), (2 where m is the level of PM effort, and δ(m), m = 0, 1, …, M, is the remaining life increment factor of PM with effort m.
More specifically, if m = 0, then v j = RL j, j ≥ 1, which means that the item is restored to as bad as old (ABAO);if m = M, the item is restored back to as good as new (AGAN); while in a more general case m ∈ (0, M), the item is partially restored, i.e. the PM activity is imperfect.
Upon interaction with airway cells, PM can elicit oxidative stress through alternative pathways; therefore, this assay can account for only a fraction of in vivo PM activity.
