Afinite capacity, finite source, Markovian queueing model with despondent arrivals, retainment of reneged customers and controllable arrival rates is considered. Using this model, a steady-state solution and system characteristics can be obtained. The measures of effectiveness of the queueing model are also derived. Numerical results are given for better understanding and relevant conclusion is presented.

1‐Oxa‐4‐thiaspiro[4.4]nonan‐2‐one (1a) and/or 1‐oxa‐4‐thiaspiro[4.5] decan‐2‐one (1b) were reacted with aniline and/or p‐chloroaniline to afford the corresponding spirothiazolidinones (2a–d). Reaction of 2a–d with chalcones gave 2‐(α – paracylbenzyl)‐4‐aryl‐1‐thia‐4‐azaspiro[4.4]nonan‐3‐one and 2‐(α‐aracylbenzyl)‐4‐aryl‐1‐thia‐4‐azaspiro[4.5]decan‐3‐one (3a–p) respectively. Compounds 3a–p were reacted with acetic anhydride and perchloric acid to yield the spiropyrano[2,3‐d]thiazol[4]ium perchlorate derivatives 4a–p. The structures of the synthesized compounds were elucidated by elemental and spectroscopic (IR and 1H‐NMR) analysis. All the prepared compounds were tested for their antimicrobial activities in comparison with tetracyclic as a reference compound.
