Under the basic assumption that both the nearly completely decomposable Markov modulated fluid model and the unperturbed fluid models are positive recurrent, we show that the stationary density of the level can be expanded as convergent power series of the aggregated stationary densities. We go further in the analysis by assuming that one or more of the unperturbed fluid queues is not necessarily positive recurrent. We provide numerical illustration.<\/jats:p>","DOI":"10.1137\/21m1395387","type":"journal-article","created":{"date-parts":[[2022,3,7]],"date-time":"2022-03-07T10:44:08Z","timestamp":1646649848000},"page":"377-404","source":"Crossref","is-referenced-by-count":3,"title":["Singularly Perturbed Markov Modulated Fluid Queues"],"prefix":"10.1137","volume":"43","author":[{"given":"Sarah","family":"Dendievel","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guy","family":"Latouche","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuanyuan","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yingchun","family":"Tang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"351","published-online":{"date-parts":[[2022,3,7]]},"reference":[{"key":"atypb1","unstructured":"L.
