Multivariate process adjustment in the presence of fixed adjustment costs is investigated in this paper. A fixed adjustment cost leads to a trade-off between adjusting a process continuously and allowing the process to drift until a bound is violated. The problem of determining the best bounded adjustment policy and the optimal bounded adjustment parameter is addressed. Although the univariate ...

This paper provides a study concerning IT value substance in IT-based industries. The applied method is a partial adjustment valuation approach, expressing that the real output is part of the preferred output. Thus, there should be a coefficient between both, which shakes the relationship in between, called a speed of adjustment. To examine the method, this theory experimented six Indonesian IT...

We consider the bandwidth optimization problem in a Generalized Processor Sharing (GPS) server to minimize the total bandwidth such that QoS requirements for each class queue are satisfied. Our previous optimization algorithm [6] requires rather long optimization time to solve the problem. We propose a new optimization algorithm based on weight vector adjustment. Numerical results show that the...

We present an optimal model based on utility functions and pricing for downlink radio resource allocation in code division multiple access (CDMA) systems. The aim of this model is to achieve the throughput maximization via dynamic price adjustment. Due to the existence of action delays, we give globally asymptotical stability results using Lyapunov-Razumikhin arguments for rate and price evolve...

Climate change threatens economic and environmental stability requires immediate action to prevent counteract its impacts. As large investments are already going into mitigation efforts, it is crucial know how best allocate them in time among the alternatives. In this work, we tackle problem using optimal control methods obtain temporal profiles of their allocation either clean energy developme...

Resource-constrained project scheduling with activity pre-emption assumes that activities are allowed to be interrupted and restarted later in the schedule at no extra cost. In the current paper, we extend this pre-emptive scheduling problem with setup times between activity interruptions and the possibility to fast track pre-emptive subparts of activities. The contribution of the paper is twof...

In the network function virtualization environment, dynamic changes in traffic will lead to of service chain resource demand, which entails timely adjustment configuration. At present, most researches solve this problem through virtual migration and link rerouting, there exist some problems such as long interruption time, excessive operation cost high penalty. This paper proposes a method confi...
