The original PFM is shown to perform well, finding a true best feasible solution with a higher probability than other competitors even when constraints are tight or near-tight. However, PFM applies simple budget allocation rules (e.g., assigning an equal number of additional observations) to solutions sampled at each search iteration and uses a rather complicated penalty sequence with several user-specified parameters. In this article, we propose an improved version of PFM, namely IPFM, which can combine the PFM with any simulation budget allocation procedure that satisfies some conditions within a general DOvS framework. We present a version of a simulation budget allocation procedure useful for IPFM and introduce a new penalty sequence, namely PS\n            <jats:sub>2<\/jats:sub>\n            <jats:sup>+<\/jats:sup>\n            , which is simpler than the original penalty sequence yet holds convergence properties within IPFM with better finite-sample performances. Asymptotic convergence properties of IPFM with PS\n            <jats:sub>2<\/jats:sub>\n            <jats:sup>+<\/jats:sup>\n            are proved. Our numerical results show that the proposed method greatly improves both efficiency and accuracy compared to the original PFM.\n          <\/jats:p>","DOI":"10.1145\/3465333","type":"journal-article","created":{"date-parts":[[2021,8,16]],"date-time":"2021-08-16T21:36:46Z","timestamp":1629149806000},"page":"1-26","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Improved Penalty Function with Memory for Stochastically Constrained Optimization via Simulation"],"prefix":"10.1145","volume":"31","author":[{"given":"Jungmin","family":"Han","sequence":"first","affiliation":[{"name":"Hanyang University, Seongdong-gu, Seoul, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seong-Hee","family":"Kim","sequence":"additional","affiliation":[{"name":"Georgia Institute of Technology, Atlanta, GA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chuljin","family":"Park","sequence":"additional","affiliation":[{"name":"Hanyang University, Seongdong-gu, Seoul, South Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2021,8,16]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1145\/352222.352225"},{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1287\/ijoc.1080.0309"},{"volume-title":"Stochastic Simulation Optimization: An Optimal Computing Budget Allocation.
