We consider the simultaneous seat-inventory control of a set of parallel flights between a common origin and destination with dynamic customer choice among the flights. We formulate the problem as an extension of the classic multiperiod, single-flight " block demand " revenue management model. The resulting Markov decision process is quite complex, owing to(More)
We develop a Markov decision process formulation of a dynamic pricing problem for multiple substitutable flights between the same origin and destination, taking into account customer choice among the flights. The model is rendered computationally intractable for exact solution by its multi-dimensional state and action spaces, so we develop and analyze(More)
BACKGROUND As one of the most populous metropolitan areas in the Pearl River Delta of South China, Shenzhen attracts millions of migrant workers annually. The objectives of this study were to compare health needs, self-reported health and healthcare utilisation of insured and uninsured migrant workers in Shenzhen, China, where a new health insurance scheme(More)
In recent years, the fractional derivative has been recognized as a powerful modeling methodology. Based on the wildly applications in engineering and sciences such as physics, mechanics, chemistry, economics and biology, research on fractional order systems is active and extensive around the world. The objective of this special issue is to report and(More)
in recent years, yet few papers provide effective computational approaches to solve the problem. We consider a resource decomposition approach to solve the problem and investigate the performance of the approach in a computational study. We compare the performance of the approach to three alternative approaches: static pricing, static bid-price control, and(More)
BACKGROUND Providing good quality primary health care to all inhabitants is one of the Chinese Government's health care objectives. However, information is scarce regarding the difference in quality of primary health care delivered to migrants and local residents respectively. This study aimed to compare patients' perceptions of quality of primary health(More)
OBJECTIVE To assess changes in the quality of primary care in two megacities following the introduction of health system reforms in China. METHODS We conducted multistage stratified random face-to-face surveys of patients visiting community health centres in Shanghai in 2011 and 2013, and Shenzhen in 2012 and 2013. Quality of primary care was measured(More)

Proof of Lemma 1. We first prove part 1. If β = 0, then h(θ, β) = 0 for all θ. Hence 0 is the unique fixed point. In the remainder of the proof, we consider the case β > 0. To establish the existence of a fixed point, observe that h(·, β) is continuous and 0 ≤ h(·, β) ≤ 1, so h(·, β) must have at least one fixed point θ on [0, 1]. We have assumed that c >(More)
