Abstract Marine container terminals play a significant role for international trade networks and global market. To cope with the rapid steady growth of seaborne market, marine terminal operators must address operational challenges appropriate analytical methods to meet needs The berth allocation scheduling problem is one important decisions faced by during operations planning. optimization sche...

in this paper, the energy efficient resource allocation in noma-based heterogeneous cellular network(hcn) systems is investigated. since energy consumption and its limitations is one of the important challenges in fifth generation of cellular networks (5g), we propose a resource allocation problem which allocates power and subcarriers to multiple users to achieve the best system energy efficien...

Let X be a Hilbert bimodule over a C∗-algebra A and OX = A⋊X Z. Using a finite section method we construct a sequence of completely positive contractions factoring through matrix algebras over A which act on sξs ∗ η as Schur multipliers converging to the identity. This shows immediately that for a finitely generated X the algebra OX inherits any standard approximation property such as nuclearit...

facility location-allocation models are used in a widespread variety of applications to determine the number of required facility along with the relevant allocation process. in this paper, a new mathematical model for the capacitated multi-facility location-allocation problem with probabilistic customer's locations and fuzzy customer’s demands under the hurwicz criterion is proposed. ...

The main objective of this research is to analyze the current situation Beirut Container Terminal. proposed methodology mimic terminal operations using a simulation model ARENA software in order identify causes queueing occurring at berth allocation. Field was conducted and both qualitative quantitate data were collected interviews, on–site observations, online vessel tracking. A base developed...

Ports are key factors in international trade, and new port terminals quite costly time consuming to build. Therefore, it is necessary optimize existing infrastructure achieve sustainability logistics. This problem more complex multi-client terminals, where quay shared among terminal operators who often have conflicting interests. Moreover, the berth allocation liquid bulk implies demanding rest...

the task of optimally assigning military ordinance to enemy targets, often termed weapon target allocation (wta) problem, has become a major focus of modern military thought where a cost effective allocation is required without degrading the required kill performance. the paper presents three main weapon allocation techniques namely uniform weapon allocation, first-in-first weapon allocation an...
