A real options approach for joint overhaul and replacement strategies with mean reverting prices
No full textDue to its significant impact on economic performance, an effective equipment overhaul and replacement strategy is a key aspect of physical asset management in capital-intensive industries, such as the mining industry. Classical approaches suggest periodic interventions based on the physical condition of the equipment, considering factors such as availability and operational costs. These fixed models generally ignore two important aspects: first, the flexibility of the decision to overhaul or replace, which may be re-evaluated within a given period, and second, the uncertainty around economic factors that may affect future maintenance decisions, such as the product price. This work improves on classical models by considering the effect of integrated price uncertainty in the definition of joint overhaul and replacement strategy, using a real options approach and a mean reversion binomial model to represent the uncertainty in price. More specifically, we develop a real options model and use a backwards recursion algorithm to determine an optimal intervention policy that maximizes expected profits. We then present a numerical study of the mining industry to validate the effectiveness of the proposed methodology. Results show that the option-based decision model economically outperforms the classical periodic strategy approach from with net present value increments ranging from 36.8 to 8.6%, according to the number of periods in the maintenance cycle, offering evidence that a new approach to equipment overhaul and replacement strategy is needed

Pádraig Mac a Liondain: bard bhí i stát ins an chrích seo
No full textÓ cheantar an Fheadha i ndeisceart Ard Mhacha don bhfile Pádraig Mac a Liondain. Is féidir dataí a bheatha a bheachtú a bhuíochas ar fhile eile ón Fheadh a bhí comhaimseartha leis, Fearghas Mac an Bheatha (fl. 1700), agus a bhuíochas fós ar ghearrchuntas beathaisnéise le Nioclás Ó Cearnaigh (c. 1802–c. 1865) ina dhiaidh sin in ARÉ LS 23 N 33. Ina thuireamh in ómós dá charaid dar tús ‘A sheanchríoch Fáil, is gnách gach léan ort’, is mar seo a chuir Mac an Bheatha é: Seacht gcéad déag an ré a dheachtaím daoibh, is triocha ina dhiaidh an réim go beacht is trí, ó theacht Mhic Dé dár saoradh go ceart is trí mhí, go Pádraig a dhul a dh’éag, mo léan, san feart faoi liag. Is é ‘an feart’ a ainmnítear in áit eile sa tuireamh céanna ná Cill an Chreagáin in aice le baile Chrois Mhic Lionnáin, Co. Ard Mhacha. D’áitigh Nioclás Ó Cearnaigh gur cailleadh Mac a Liondain ‘in April 1733 in the 68th year of his age’, más fíor, rud a fhágfadh gur timpeall na bliana 1665 a rugadh é.Peer-review status unspecifiedCheckdate as researcher profile gives different book title and publication date?
