This study considers a multi-class network resource in a competitive market where each user endowed with an initial budget will purchase bandwidth from each class of the network resource to maximise its utility function. The authors use revenue as the utility function for the service provider, and enhance Kelly’s utility function by including delay as the quality of service (QoS) parameter for ...

This paper proposes a global cumulative constraint for cyclic scheduling problems. In cyclic scheduling a project graph is periodically re-executed on a set of limited capacity resources. The objective is to find an assignment of start times to activities such that the feasible repetition period λ is minimized. Cyclic scheduling is an effective method to maximally exploit available resources by...

The gap in automation between MIP/SAT solvers and those for constraint programming and constraint-based local search hinders experimentation and adoption of these technologies and slows down scientific progress. This paper addresses this important issue: It shows how effective local search procedures can be automatically synthesized from models expressed in a rich constraint language. The synth...

Several approaches for cross-layer design, e.g., coordinating the traditionally separated layers in wireless networks, have been proposed. However, protocols that are close to achieving the performance bounds are still lacking. We propose three distributed algorithms for joint congestion control and resource allocation in networks with variable capacities subject to a global resource constraint...

Language is a hallmark of intelligence, and endowing computers with the ability to analyze and generate languagea field of research known as Natural Language Processing (NLP)has been the dream of Artificial Intelligence (AI). In this paper we give a perspective of NLP from the point of view of ambiguity processing and computing under resource constraint. Language is fraught with ambiguity at al...

Resource (power and bandwidth) allocation is an important issue in orthogonal frequency division multiple access (OFDMA) systems. For multicell systems, the interference across different cells makes the optimization of resource allocation difficult. For finite systems, a constraint on the rise over thermal (ROT) is placed to alleviate the intercell interference. A hybrid scheme with equal recei...

We propose a transformation-based scheduling algorithm for the problemgiven a loop construct, a target initiation interval and a set of resource constraints, schedule the loop in a pipelined fashion such that the iteration time of executing an iteration of the loop is minimized. The iteration time is an important quality measure of a data path design because it affects both storage and control ...

We study joint rate control and resource allocation with a packet collision constraint that maximizes the total utility of secondary users in cognitive radio networks. We formulate and decouple the original optimization problem into separable subproblems and then develop an algorithm that converges to optimal rate control and resource allocation. The proposed algorithm can operate on different ...

Project scheduling is the next step once project planning completed. This requires knowledge and depth of activities, dependencies between activities and, duration activities. Creating designing a realistic schedule biggest challenges manager faces. There are some common problems that can be impact towards delay or performance: Assigning Resource Constraint, Managing Unknown Change Estimating T...

Time constraints resource usage object selection and condition e ect causal constraints are handled as an integral part of the overall system structure by treating specialised constraint management as supporting the core decision making components in the architecture A close coupling of planning and time or resource scheduling is therefore possible within a system employing an activity based pl...
