For over 20 years, activity scanning has been sup planted by the three-phase approach, which combines elements of both event scheduling and activity scanning. The three-phase approach is presented and discussed against the world view char acteristics developed by Hooper.\n                  <\/jats:p>","DOI":"10.1177\/003754978604700505","type":"journal-article","created":{"date-parts":[[2007,3,4]],"date-time":"2007-03-04T20:53:41Z","timestamp":1173041621000},"page":"208-210","source":"Crossref","is-referenced-by-count":16,"title":["The three-phase approach: A comment on \"strategy-related characteristics of discrete-event languages and models\""],"prefix":"10.1177","volume":"47","author":[{"given":"Robert M.","family":"O'Keefe","sequence":"first","affiliation":[{"name":"Department of Computer Science Virginia Polytechnic Institute and State University Blacksburg, Virginia 24061"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1986,11,1]]},"reference":[{"key":"atypb1","volume-title":"Discrete-Event System Simulation","author":"Banks, J.","year":"1984"},{"key":"atypb2","volume-title":"Pilot GSP IV Manual.
