Warranties are very\nwidespread and serve many purposes, including protection for producer,\nseller, and consumer. They are used as signals of quality and\nas elements of marketing strategies. In this study we review the notion\nof an online convex optimization algorithm and its variations,\nand apply it in warranty context. We introduce a class of profit functions,\nwhich are functions of warranty, and use it to formulate the\nproblem of maximizing the company's profit over time as an online\nconvex optimization problem. We use this formulation to present an\napproach to setting the warranty based on an online algorithm with\nlow regret. Under a dynamic environment, this algorithm provides\na warranty strategy for the company that maximises its profit over\ntime.<\/jats:p>","DOI":"10.1155\/2009\/414507","type":"journal-article","created":{"date-parts":[[2009,4,16]],"date-time":"2009-04-16T06:36:07Z","timestamp":1239863767000},"page":"1-14","source":"Crossref","is-referenced-by-count":0,"title":["Warranty Optimization in a Dynamic Environment"],"prefix":"10.1080","volume":"2009","author":[{"given":"Nedialko B.","family":"Dimitrov","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering, University of Texas at Austin, 1 University Station C2200, Austin, TX 78712, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefanka","family":"Chukova","sequence":"additional","affiliation":[{"name":"School of Mathematics, Victoria University of Wellington, P.O.
