Strategic behavior and social optimization in markovian vacation queues the case of heterogeneous customers
European Journal of Operational Research, 2012Co-Authors: Pengfei Guo, Refael HassinAbstract:Abstract We consider a single server queueing system in which service shuts down when no customers are present, and is resumed when the queue length reaches a given critical length. We assume customers are heterogeneous on delay sensitivity and analyze customers’ Strategic Response to this mechanism and compare it to the overall optimal behavior. We provide algorithms to compute the equilibrium arrival rates and also derive the monotonicity of equilibrium and optimal arrival rates. We show that there may exist multiple equilibria in such a system and the optimal arrival rate may be larger or smaller than the decentralized equilibrium one.

Strategic behavior and social optimization in markovian vacation queues
Operations Research, 2011Co-Authors: Pengfei Guo, Refael HassinAbstract:We consider a single server queueing system in which service shuts down when there are no customers present and is resumed only when the queue length reaches a given critical length. We analyze the Strategic Response of customers to this mechanism and compare it to the overall optimal behavior, with and without information on delay. The results are significantly different from those obtained when the server is continuously available. We show that there may exist multiple equilibria in such a system and the optimal arrival rate may be greater or smaller than that of the decentralized equilibrium. Finally, the critical length is taken as a decision variable, and the optimal operations policy is discussed by taking Strategic customers into consideration.

explorative versus exploitative business model change the cognitive antecedents of firm level Responses to disruptive innovation
Social Science Research Network, 2015Co-Authors: Oleksiy Osiyevskyy, Jim DewaldAbstract:We develop a typology of incumbent adaptations to emerging disruptive business model innovations, based on two generic strategies: (i) explorative adoption of a disruptive business model, (ii) exploitative strengthening of the existing business model. We derive and test hypotheses concerning the cognitive antecedents of managerial intentions to embrace each of the two adaptation strategies. The results from our study of the real estate brokerage industry show that the explorative intentions are driven by opportunity perception, perceived performance-reducing threat, and risk experience. Exploitative intentions are negatively associated with perceived critical threat and industry tenure, and positively associated with risk experience. We contribute to the literature on disruptive business models by combining prior research into a definable framework, and by testing the cognitive influences on Strategic Response.

Leadership and early Strategic Response to the SARS-CoV- 2 pandemic at a COVID-19 designated hospital in South Africa
'South African Medical Association NPC', 2020Co-Authors: Parker A., Karamchand S., Schrueder N., Lahri S., Rabie H., Aucamp A., Abrahams R., Ciapparelli P., Erasmus D. S., Cotton M. F.Abstract:CITATION: Parker, A. et al. 2020. Leadership and early Strategic Response to the SARS-CoV- 2 pandemic at a COVID-19 designated hospital in South Africa. South African Medical Journal, 110(6), doi:10.7196/SAMJ.2020v110i6.14809.The original publication is available at http://www.samj.org.zaWhile many countries are preparing to face the COVID-19 pandemic, the reported cases in Africa remain low. With a high burden of both communicable and non-communicable disease and a resource-constrained public healthcare system, sub-Saharan Africa is preparing for the coming crisis as best it can. We describe our early Response as a designated COVID-19 provincial hospital in Cape Town, South Africa (SA).While the first cases reported were related to international travel, at the time of writing there was evidence of early community spread. The SA government announced a countrywide lockdown from midnight 26 March 2020 to midnight 30 April 2020 to stem the pandemic and save lives. However, many questions remain on how the COVID-19 threat will unfold in SA, given the significant informal sector overcrowding and poverty in our communities. There is no doubt that leadership and teamwork at all levels is critical in influencing outcomes.http://www.samj.org.za/index.php/samj/article/view/12912Publisher's versio
