Cloud computing is a flexible computing model where resources are allocated and deal located dynamically. The dynamic nature of allocating resources provide scope for optimizing the resources utilization. However the key challenge is to optimize the resource utilization without impacting the applications. In this context we argue that knowing the usage (behavior) of applications is important and using...
The supply chain system consists of one supplier and one retailer. When demand function and cost were disrupted simultaneously, how the disruptions effect the supply chain was discussed, and the disruption management decisions of individuals were analyzed. The optimal strategies that supply chain replied to the disruptions were proposed, and an improved revenue sharing contract was presented under...
Resource pools are collections of computational resources which can be shared by different applications. The goal with that is to accommodate the workload of each application, by splitting the total amount of resources in the pool among them. In this sense, utility functions have been pointed as the main tool for enabling self-optimizing behaviour in such pools. The goal with that is to allow resources...
The supply chain system consists of one supplier and multiple retailers. When demand function and cost were disrupted simultaneously, how the disruptions effect the supply chain was discussed, and the disruption management decisions of individuals were analyzed. The optimal strategies that supply chain replied to the disruptions were proposed, and an improved revenue sharing contract was presented...
Based on dimensional analysis theory, the criterion equation of the flow of polymer solution through separate layer injection allocation of cylindrical cavity with a nozzle and a jet target is established; the viscosity loss regression formulae of the flow of polymer solution through separate layer injection allocation of cylindrical cavity with a nozzle and a jet target are obtained through regression...
Loops are predominant in computer programs. Data dependencies in loops dictate their execution time. An algorithm to execute loops in parallel based on the preordering of data in is presented in this paper. This algorithm can be applied to chip multiprocessors. The algorithm performs a fair share allocation of the loops to the available processors. Data accessed for loops accessed in a processor are...
Resource allocation is an important issue in cognitive radio systems. It can be done by carrying out negotiation among secondary users. However, significant overhead may be incurred by the negotiation since the negotiation needs to be done frequently due to the rapid change of primary users' activity. In this paper, a channel selection scheme without negotiation is considered for multi-user and multi-channel...
This paper addresses the cyclic multi-hoist scheduling problem. The problem arises in automated electroplating lines where multiple hoists are operating on a shared track. The considered processing sequences may be different from the location sequence of the tanks and may contain loops, i.e. multiple usages of single tanks within a sequence. In addition the electroplating line may be equipped with...
In the military conflict, the defending side may suffer threats from different attackers at the same time. This kind of situation is called campaign between single-kind arms and multi-kind arms in this article. By introducing the campaign superiority parameter(CSP), the optimal military strength allocation problem is studied for campaign between single-kind arms and multi-kind arms. Firstly, the general...
The purpose of this paper is to investigate the coordination problem of a three-level supply chain which consisted of a manufacturer, a distributor and a retailer. Using a quantity discount contract and a revenue sharing contract, we derived conditions under which the three-level supply chain can be coordinated so that the maximal potential profit is realized. By adjusting the parameters of the contracts,...
Resource sharing on the Internet is becoming increasingly pervasive. Recently, there is growing interest in distributed systems such as peer-to-peer and grid, with efforts being directed towards resource allocation strategies that incentivize users to share resources. While combinatorial auctions can perform multiple resource type allocations, it is computationally a NP-complete problem. Thus, allocation...
Many applications of existing grid systems are usually deployed on grid nodes in a static manner. Grid computing nodes with highly demanded applications deployed on are always busy; while the others are idle. If these applications could be dynamically deployed on idle nodes, the system performance would be greatly improved. However, the overhead (e.g., package download) caused by dynamic deployment...
With the background of the mechanism design of the present e-Auction and of multi-object auction, the paper offers such a design of a special sequential second-price sealed-bid auction of 2 differentiated objects, which is steadily transferring the auctioneers' private information into common knowledge step by step.,analyzing and comparing the bidders' preferred bidding and the auctioneers' expectant...
Convex optimization has been widely used to model bandwidth allocation policies among TCP flows in the Internet. When the offered load is less than capacity, stochastic stability of networks using such policies has been established for exponentially distributed file sizes. The problem has remained open for general file size distributions, which is very relevant as it is well known that Internet file...
Mechanisms for allocation of one or many goods to a number of agents are proposed in this paper. The goal is to propose mechanisms in a general setting where the goods might be divisible or indivisible. A mechanism in the Groves class that is dominant strategy incentive compatible and almost budget balanced is obtained. In the case of one or more indivisible goods, the proposed mechanisms fall back...
This paper and the presentation will compare emissions trading scheme in the European Union and the recently established Regional Greenhouse Gas Initiative in the US, looking at their similarities and differences, as well as results that are available so far. In addition, the paper investigates effects that emissions constraints may have on market clearing prices in electricity markets. The analysis...
The current art in optimal combinatorial auctions is limited to handling the case of single units of multiple items, with each bidder bidding on exactly one bundle (single minded bidders). This paper extends the current art by proposing an optimal auction for procuring multiple units of multiple items when the bidders are single minded. We develop a procurement auction that minimizes the cost of procurement...
In this paper, we consider an emerging scenario in sponsored Web search auctions where ad networks would be involved as intermediaries between a search engine and its advertisers. In this context, we address the problem of the ad network identifying a bid profile that makes the sponsored search auction attractive to the registered bidders. Given (1) the valuation of the advertisers competing for sponsored...
Resource allocation in grid environment is a complex undertaking due to the heterogeneity and dynamic nature aroused by wide area sharing. To address the heterogeneous and computationally intractable problem of resource allocation optimization in grid, this paper presents an allocation algorithm for parallel tasks based on particle swarm optimization. The heterogeneity of grid user is tackled by introducing...
In this paper, we focus on proactive radio resource management schemes that retain the quality of the individual connections by pre-reserving the needed resources in a cellular network. We propose a new scheme, which improves older proactive solutions. Typically, in such solutions an improvement in call dropping probability negatively impacts new call blocking probability. We improve this framework...
