The distribution or delivery process is one factor that affect customer satisfaction as the goal of supply chain. In order for chain to be competitive in competition, time an important manage, so it could provide high service level value. One affects center location. A strategic location would facilitate and speed up process. This research discusses model determining made at right amount by ana...

The edge dominating set (EDS) and edge cover (EC) problems are classical graph covering problems in which one seeks a minimum cost collection of edges which covers the edges or vertices, respectively, of a graph. We consider the generalized partial cover version of these problems, in which failing to cover an edge, in the EDS case, or vertex, in the EC case, induces a penalty. The objective is ...

The design of nature reserves is becoming, more and more, a crucial task for ensuring the conservation endangered wildlife. In order to guarantee preservation species general ecological functioning, designed must typically verify series spatial requirements. Among required characteristics, practitioners researchers have pointed out two aspects: (i) connectivity, so as avoid fragmentation, (ii) ...

The problem of maximal hub covering as a challenging problem in operation research. Transportation programming seeks to find an optimal location of a set of hubs to reach maximum flow in a network. Since the main structure's parameters of the problem such as origin-destination flows, costs and travel time, change periodically in the real world applications, new issues arise in handling it. In t...

Three windshear/microburst detection algorithms are used operationally at the Hong Kong International Airport. Their performance is studied in present article by assuming availability of complete set meteorological data from numerical weather prediction model output. Only selected tropical cyclone cases considered. The evaluated using pilot reports windshear. It turns out that glide path scan w...
