When system operators face excess demand, they can either add capacity or adapt their management techniques to deal with their limited resources\u2014this article considers the latter. We examine system configuration options and the resultant effects on customer service levels in a simulated dial-up modem pool operation. Specifically, we look at a single pool operation and examine the effects of imposing time limits in a seriously overloaded system. We analyze the results on several key customer service measures. The results show that imposing these limits will have a distinct, nonlinear impact on these measures. Customer productivity and actual system load are shown to have major impacts on the performance measures. Interactions between several system and environmental parameters are also discussed.<\/p>","DOI":"10.4018\/jisss.2010093003","type":"journal-article","created":{"date-parts":[[2010,4,16]],"date-time":"2010-04-16T14:50:12Z","timestamp":1271429412000},"page":"26-48","source":"Crossref","is-referenced-by-count":0,"title":["Connect Time Limits and Performance Measures in a Dial-Up Modem Pool System"],"prefix":"10.4018","volume":"2","author":[{"given":"Paul F.","family":"Schikora","sequence":"first","affiliation":[{"name":"Indiana State University, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael R.","family":"Godfrey","sequence":"additional","affiliation":[{"name":"University of Wisconsin Oshkosh, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brian D.","family":"Neureuther","sequence":"additional","affiliation":[{"name":"State University of New York - College at Plattsburgh, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2432","reference":[{"key":"jisss.2010093003-0","doi-asserted-by":"publisher","DOI":"10.1016\/j.cam.2007.12.016"},{"key":"jisss.2010093003-1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejor.2007.05.035"},{"key":"jisss.2010093003-2","unstructured":"Auckland, J.
