It is assumed tha...

On-demand computing ability and efficient service delivery are the major benefits of cloud systems. The limitation in resource availability single data centers causes extraction additional resources from providers group. federation scheme dynamically increases response to requests. dynamic increase count leads excessive energy consumption, maximum cost, carbon footprints emission. Hence, reduct...

This paper investigates the decision making of firms with two different objectives – profit maximization and sales maximization, and compares their responses when encountering a higher per unit production cost or if per unit tax is imposed. The discussion in this paper is a follow up of Li and Yao [1], except in this case, a more comprehensive literature review is provided, and a very restricte...

Simulations have been conducted for two purposes, namely, (1) to validate our analytical results (Theorems 1 and 2); (2) and to find more effective queueing disciplines which increase the net profit of a service provider. In Table 1, we show our simulation results by using the same parameters in Figures 1–10. For each λ = 6.05, 6.15, ..., 6.95, we trace the behavior of an M/M/m queueing system ...

This paper examines the problem of how to design incentive-compatible mechanisms in environments in which the agents’private information evolves stochastically over time and in which decisions have to be made in each period. The environments we consider are fairly general in that the agents’ types are allowed to evolve in a non-Markov way, decisions are allowed to a¤ect the type distributions a...

Online Social Networks (OSNs) attract billions of users to share information and communicate where viral marketing has emerged as a new way to promote the sales of products. An OSN provider is often hired by an advertiser to conduct viral marketing campaigns. The OSN provider generates revenue from the commission paid by the advertiser which is determined by the spread of its product informatio...

This paper concerns with a mathematical model considering customer satisfaction requirements in a supply chain. The model tradeoffs the supply chain ability to fulfill the customers’ requirements and the limited budget in a variety of production phases. The decisions made here help to determine the profit provider price and economic quantity while the effective supplier and priori requireme...

In this paper, we present an accurate and fast algorithm for maximizing profits through buffer size optimization for production lines. We consider both buffer space cost and average inventory cost with distinct cost coefficients for different buffers, and we include a nonlinear production rate constraint. To solve the problem, a corresponding unconstrained problem is introduced and a nonlinear ...

This paper presents an optimal method and a heuristic approach which aims at maximizing the profit when responding to a set of customer enquiries under limited capacity. The model takes into consideration the quantity of available-to-promise (ATP) which measures the capability to fill customer orders, along with enquiry quantity and product price. The optimal method and the heuristic approach a...

N P-hard problem as a total distance minimization problem. Natural extension of the notorious traveling salesperson problem (TSP) with… Delivery vehicles (homogeneous or heterogeneous fleet) have a limited capacity. One or more nodes in the graph (single depot vs. multi-depots) are designated as origins of routes. Each route should emanate from such an origin node. The rest of the nodes are ide...
