Mobile Crowdsourcing, which uses a crowd of workers to complete computer-complexity tasks, has become more and popular. How maximize the total profit, is difference between task utility worker costs, key design goal in such crowdsourcing system. However, this problem extremely hard because even offline situation, been proved be NP-hard. In online we need consider not only future unknown arrival...

we developed an inventory model for decaying items with selling price dependent demand in inflationary environment. deterioration rate is taken as two parameter weibull distribution. shortages in inventory are allowed with partial backlogging. backlogging rate is taken as exponential decreasing function of time. profit maximization technique is used in this study.

We study the design of pricing mechanisms and auctions when the mechanism designer does not know the distribution of buyers’ values. Instead the mechanism designer receives a set of samples from this distribution and his goal is to use the sample to design a pricing mechanism or auction with high expected profit. We provide generalization guarantees which bound the difference between average pr...

In a diffusion model of an enterprise with variable scale, conditions are given for the maximization of ‘profit’ (expected total discounted withdrawals) to lead to bankruptcy almost surely. The optimal withdrawal policy is an ‘overflow policy’: the withdrawal rate is zero if the asset level is below a ‘barrier’, and equal to the maximum rate if the asset level is at least equal to the barrier. ...

This paper addresses the problem of profit maximization of a power plant by utilizing three different fuel systems in an optimal manner. Pontryagin’s maximum principle is used to derive properties of the optimal control strategy. These properties give rise to a switching function. Subsequently, certain heuristics are introduced and used in combination with discrete optimization to obtain an ini...

The existing Web service management solutions are almost exclusively focused on optimization of technical QoS metrics (e.g., availability). However, financial (e.g., profit) and other business value metrics (e.g., customer satisfaction) are more important than technical QoS metrics. We discuss the challenges of business value modeling and maximization in autonomic (e.g., self-healing) Web servi...
