This work empirically assesses the degree to which inventory decisions made by entrepreneurs and small businesses are informed by the logic underlying the newsvendor or base stock model and are influenced by the decision-maker’s risk profile. We used a weband email-based survey, combined with a telephone follow-up to elicit risk profiles, obtaining 51 usable responses. Our findings suggest that...

This paper is concerned with dynamic control of stochastic processing networks. Specifically, it follows the so called “heavy traffic approach,” where a Brownian approximating model is formulated, an associated Brownian optimal control problem is solved, the solution of which is then used to define an implementable policy for the original system. A major challenge is the step of policy translat...

Most advanced nations today are witnessing a peace-time public debt surge that match post World War levels. This raises concerns about fiscal financing and liquidation of the stock of debt specially in the face of changing demographics. United Kingdom being one of the advanced nations with a high level of public debt and an aging population is facing similar issues of fiscal financing. This pap...

Fair Queuing was invented to ensure that every flow gets its fair share of the total bandwidth. Efficient Fair Queuing Using Deficit Round-Robin, DRR, proposed by Shreedhar and Varghese [1], reduces the work to process each packet from O(log(n)) to O(1). DRR was also extended to accommodate latency-critical flows. DRR+ uses a timer to police each latency-critical flow, and was shown to have a l...

Broadcasts of Insurance Institute for Highway Safety high-speed automotive crash tests on NBC’s Dateline do not affect either market shares or stock prices. However, injury claims within a market class are highly correlated with crash test ratings. Inattention to the tests may be a consequence of the manner in which the crash tests have been presented and because the crashworthiness of the U.S....

This article focus on the behaviour of a multi-product batch production line with fixed capacity which is scheduled according to inaccurate inventories (IRI). We assume an unlimited supply of raw materials and a constant demand for the different finished goods. The ordering policy of this production line is based on a (Q,R) continuous review, lost-sales inventory model and on given priority for...

OBJECTIVES Scalp acupuncture (SA) is a commonly used therapeutic approach for primary intracerebral hemorrhage (ICH) in Traditional Chinese Medicine (TCM), but the efficacy and safety of SA therapy are still undetermined. The aim of this study is to systematically evaluate the efficacy and safety of SA therapy for the treatment of acute hypertensive ICH. METHODS Literature reports with random...

Buyang Huanwu Decoction (BHD) is a well-known traditional Chinese herbal prescription for treating stroke-induced disability. The objective of this study was to evaluate the efficacy and safety of BHD for acute ischemic stroke. A systematic literature search was performed in 6 databases until February 2012. Randomized controlled clinical trials (RCTs) that evaluate efficacy and safety of BHD fo...
