A heuristic evaluation ‎ model is proposed for assessing the usability of Top 10 Iraq university websites. ‎This based on 3 hierarchies website criteria levels. The top hierarchy level consists five categories: design and layout, learnability, content, performance, errors. In middle 18 subcategories, in bottom 44 elements were described. utilized both automated tools observation methods. To val...

vehicle routing problem (vrp) is one of the major problems in the transportation and distribution planning. in the most previous studies, the objective of vrp models was distance and vehicle related costs. however in many industrial cases along with routing distance, vehicle loading amount is a factor of cost function. in this paper, we formulate a mixed integer non-linear programming (minlp) m...

In hybrid flow shop scheduling problem (HFS) with unrelated parallel machines, a set of n jobs are processed on k machines. A mixed integer linear programming (MILP) model for the HFS scheduling problems with unrelated parallel machines has been proposed to minimize the maximum completion time (makespan). Since the problem is shown to be NP-complete, it is necessary to use heuristic methods to ...

One of the most common methods in natural family planning, the "temperature method", usually is based on a rule of thumb (due to the WHO) in order to determine the moment of temperature rise. We will replace that that fuzzy rule by a clear "yes" or "no" using a statistical method, the Sequential Probability Ratio Tests (SPRT). The resulting simple algorithm is able to detect the rise of tempera...

The reliability-based heuristic search methods for maximum likelihood decoding (MLD) generate test error patterns (or, equivalently, candidate codewords) according to their heuristic values. Test error patterns are stored in lists and its space complexity is crucially large for MLD of long block codes. Based on the decoding algorithms both of Battail and Fang and of its generalized version sugg...

The solutions used to solve bi-level congestion pricing problems are usually based on heuristic network optimization methods which may not be able to find the best solution for these type of problems. The application of meta-heuristic methods can be seen as viable alternative solutions but so far, it has not received enough attention by researchers in this field. Therefore, the objective of thi...
