This paper considers a biobjective transportation problem with various fuzzy objective functions coefficients. Fuzzy coefficients can be of different types such as triangular, trapezoidal, (semi) $L-R$, or flat (semi) $L-R$ fuzzy numbers. First, we convert the problem to a parametric interval biobjective transportation problem using $gamma$-cuts of fuzzy coefficients. Then, we consider a fix $g...

Consider the network from [1, Fig. 3b]: A B a. Assume the network grows as described in [1, Fig. 3b], by duplication of a gene (node) chosen uniformly at random. For the nodes marked A and B, respectively, compute the expected number of connections a random descendant has after a single duplication step, i.e. when the network has grown to seven nodes. The three possible topologies we can have a...

in this paper,  a heuristic algorithm is proposed in order to solve a nonlinear lexicography goal programming (nlgp) by using an efficient initial point. some numerical experiments showed that the search quality by the proposed heuristic in a multiple objectives problem depends on the initial point features, so in the proposed approach the initial point is retrieved by data envelopment analysis...

vations from each of p genes. In [1] it is assumed that i , j = arg max{|β̂ij |} can be computed in time O(1) (it is also assumed that the inner products for updating the β̂ values can be computed in time O(1), but this is actually possible by using the fact that 〈Yk T , Y ∗ i − ηβ̂ijYj〉 = 〈Yk T , Y ∗ I 〉 − ηβ̂ij〈Yk T , Yi〉). This makes some sense, as the algorithm is implemented in Matlab and buil...

An efficient optimum solution is presented for a real-life employee daysoff scheduling problem with a three-week cycle. Over a given work cycle, each worker is given 14 successive workdays and 7 successive off days. This three-week days-off timetable is referred to as the (14, 21) schedule. Given different labor demands for each day of the week, the primary objective is to minimize the number o...

Recent healthcare legislation, financial pressures, and regulatory oversight have increased the need to create improved mechanisms for performance measurement, quality management tracking, and outcomesbased research. The Anesthesia Quality Institute (AQI) has established the National Anesthesia Clinical Outcomes Registry (NACOR) to support these requirements for a wide-range of customers includ...
