Firms acquire network capacity from multiple suppliers which offer different Quality of Service (QoS) levels. After acquisition, day-to-day operations such as video conferencing, voice over IP and data applications are allocated between these acquired capacities by considering QoS requirement of each operation. In optimal allocation scheme, it is generally assumed each operation has to be place...

In this paper, we proposed the fuzzy multi-job and multi-company workers assignment problem with penalty. Our purpose is obtaining the optimal solution the assignment problem, where n jobs are assigned to m workers (m>n), each job must be assigned to one and only one worker and each worker could be received one job or do not receive any job. Furthermore, there are k company where each worker be...

We present a general theory of exact penalty functions with vectorial (multidimensional) parameter for optimization problems in infinite dimensional spaces. In comparison the scalar case, use parameters provides much more flexibility, allows one to adaptively and independently take into account violation each constraint during an process, often leads better overall performance method using func...

although our religious doctrines have given special importance to the execution of legal punishments and penalties for their conventional outcomes, the execution of legal punishments or their suspension in the age of occultation of the infallible imam (a.s.) has been one of the controversial issues in jurisprudence, to the extent that it has created two conflicting fronts; one, a group of disti...

We consider a convex optimization problem on linearly constrained cones in a Euclidean Jordan algebra. The cost function consists of a quadratic cost term plus a penalty function. A damped Newton algorithm is proposed for minimization. Quadratic convergence to the global minimum is shown using an explicit step-size selection.

 In recent years, mobile networks have faced with the increase of traffic demand. By emerging mobile applications and cloud computing, Mobile Cloud Computing (MCC) has been introduced. In this research, we focus on the 4th and 5th generation of mobile networks. Data Centers (DCs) are connected to each other by high-speed links in order to minimize delay and energy consumption. By considering a ...

today’s energy reauiraments have produced an increase in drilling activities all around the world. among this situation is the fact that all the operators are trying to minimize cost without reduction in quality. so, they are looking for new types of contracts between all drilling companies, contractors and suppliers until that with make agreement between them have successful operations. in thi...

In this paper we consider the scheduling problem with machine cost and rejection penalties. For this problem, we are given a sequence of independent jobs, each being characterized by its processing time (size) and its penalty. No machine is initially provided, and when a job is revealed the algorithm has the option to purchase new machines. Right when a new job arrives, we have the following ch...

We consider the indirect covering subtree problem (Kim et al., 1996). The input is an edge weighted tree graph along with customers located at the nodes. Each customer is associated with a radius and a penalty. The goal is to locate a tree-shaped facility such that the sum of setup and penalty cost is minimized. The setup cost equals the sum of edge lengths taken by the facility and the penalty...
