According to Pontryagin’s maximum principle, optimal solutions are concatenations of singular and bang arcs and exhibit the chattering or <jats:italic>Fuller</jats:italic> phenomenon, which is problematic for applications. To avoid chattering, we introduce a reduced model which is still biologically relevant and retains the important structural features of the original problem. Using a combination of analytical and numerical methods, we show that the singular arc is dominant in the studied DOCPs and exhibits the <jats:italic>turnpike</jats:italic> property. This property is further used in order to design simple and realistic suboptimal control strategies.</jats:p>"}]},{"status":"public","user_id":"477","volume":189,"_id":"45640","publisher":"Springer","quality_controlled":"1","project":[{"name":"SFB 901 - A3: SFB 901 - Der Markt für Services: Anreize, Algorithmen, Implementation (Subproject A3)","_id":"7","grant_number":"160364472"},{"grant_number":"160364472","_id":"1","name":"SFB 901: SFB 901: On-The-Fly Computing - Individualisierte IT-Dienstleistungen in dynamischen Märkten "},{"name":"SFB 901 - A: SFB 901 - Project Area A","_id":"2"}],"citation":{"mla":"Hoof, Simon. “Dynamic Monopolistic Competition.” <i>Journal of Optimization Theory and Applications</i>, vol. 189, no. 2, Springer, 2021.","bibtex":"@article{Hoof_2021, title={Dynamic Monopolistic Competition}, volume={189}, number={2}, journal={Journal of Optimization Theory and Applications}, publisher={Springer}, author={Hoof, Simon}, year={2021} }","ama":"Hoof S.

The analysis is restricted to bounded quantity and price paths that fulfill the necessary conditions for an open-loop Nash equilibrium. I show that there exists a symmetric steady state and that its stability depends on the degree of product differentiation. When moving from complements to perfect substitutes, the steady state is either a locally asymptotically unstable (spiral) source, a stable (spiral) sink or a saddle point. I further apply the Hopf bifurcation theorem and prove the existence of limit cycles, when passing from a stable to an unstable steady state. Lastly, I provide a numerical example and show that there exists a stable limit cycle."}],"publication":"Journal of Optimization Theory and Applications","issue":"2","type":"journal_article","department":[{"_id":"205"},{"_id":"475"}],"date_created":"2023-06-15T14:05:25Z"},{"language":[{"iso":"eng"}],"doi":"10.1007/s10957-015-0857-y","publication_identifier":{"issn":["0022-3239","1573-2878"]},"author":[{"first_name":"Rashed","last_name":"Khanjani Shiraz","full_name":"Khanjani Shiraz, Rashed"},{"id":"31858","last_name":"Tavana","first_name":"Madjid","full_name":"Tavana, Madjid"},{"last_name":"Di Caprio","first_name":"Debora","full_name":"Di Caprio, Debora"},{"full_name":"Fukuyama, Hirofumi","first_name":"Hirofumi","last_name":"Fukuyama"}],"title":"Solving Geometric Programming Problems with Normal, Linear and Zigzag Uncertainty Distributions","year":"2016","intvolume":"       170","publication_status":"published","date_updated":"2024-05-11T11:52:17Z","date_created":"2024-05-11T11:25:18Z","department":[{"_id":"277"}],"type":"journal_article","publication":"Journal of Optimization Theory and Applications","issue":"1","publisher":"Springer Science and Business Media LLC","_id":"54166","page":"243-265","volume":170,"user_id":"51811","status":"public","citation":{"mla":"Khanjani Shiraz, Rashed, et al. “Solving Geometric Programming Problems with Normal, Linear and Zigzag Uncertainty Distributions.” <i>Journal of Optimization Theory and Applications</i>, vol. 170, no. 1, Springer Science and Business Media LLC, 2016, pp. 243–65, doi:<a href=\"https://doi.org/10.1007/s10957-015-0857-y\">10.1007/s10957-015-0857-y</a>.","ama":"Khanjani Shiraz R, Tavana M, Di Caprio D, Fukuyama H.
