In most stochastic inventory models, such as continuous review models and periodic review models, it has been assumed that the stockout period during a cycle is small enough to be neglected so that the average number of cycles per year can be approximated as D/Q, where D is the average annual demand and Q is the order quantity. This assumption makes the problem more tactable, but it should not ...

Self measurement of blood pressure was introduced in the 1930s and is now practised by almost 10% of the general population of the United Kingdom. Because blood pressure monitors are now readily available and cheap (as little as £10; €11.8; $15), self monitoring is likely to increase—in theUnitedStates andEurope up to two thirds of people with hypertension self monitor. At present we have insuf...

The main goal of evidence‐based neonatology synopsis is to inform and alert neonatal practitioners of the latest advances in neonatal literature. Our reviews focus on high quality, practice changing original research articles, and systematic reviews. These articles are summarized and presented with a commentary of a clinical expert. Commentators are selected by the editorial team and invited to...

the real world is full of uncertainties and parameters such as demand cannot be determined exactly. in this case, using crisp (exact) values and statistical methods due to absence of sufficient information, seems unwise. so in this paper, an approach is presented for using fuzzy numbers in continues review policy related decision-making. in this supply chain, there are two enterprises, a and b ...

background: in medical research, dichotomisation of continuous variables is a widespread use approach. however, it has been argued that dichotomisation might be waste of information. the aim of this paper is to review the main methods to dichotomise continuous data, to address practical issues around dichotomisation methods, and to investigate whether dichotomisation is always a bad idea. metho...
