Cost-Sharing Approximations for h+
نویسندگان
چکیده
Relaxations based on (either complete or partial) ignoring delete effects of the actions provide the basis for some seminal classical planning heuristics. However, the palette of the conceptual tools exploited by these heuristics remains rather limited. We study a framework for approximating the optimal cost solutions for problems with no delete effects that bridges between certain works on heuristic search for probabilistic reasoning and classical planning. In particular, this framework generalizes some previously known, as well as suggests some novel, tools for heuristic estimates for Strips planning.

متن کاملA New Approach for Accurate Pricing of Reactive Power and Its Application to Cost Allocation in Deregulated Electricity Markets
Reactive power management plays an essential role in the secure operation of the power system as an ancillary service. Although in electricity markets, the particular attention is paid to active power, the reactive power also plays an important on total generation costs of electricity. On the other hand, as it is mainly confined to local consumption, to avoid market power and maintain the se...
متن کاملIncentive mechanism based on cooperative advertising for cost information sharing in a supply chain with competing retailers
This paper proposes a new motivation for information sharing in a decentralized channel consisting of a single manufacturer and two competing retailers. The manufacturer provides a common product to the retailers at the same wholesale price. Both retailers add their own values to the product and distribute it to consumers. Factors such as retail prices, values added to the product, and local ad...

The members of a chain always try to find new ways in order to raise their profit. Hence we intend to study two different scenarios in a single item two-echelon green supply chain including two manufacturers and one retailer to study the effects of two effective contracts on members’ profit. Two scenarios are discussed and in first one, first manufacturer proposes quantity discount contract to ...
متن کاملElectric-vehicle car-sharing in one-way car-sharing systems considering depreciation costs of vehicles and chargers
In recent years, car-sharing systems have been announced as a way to increase mobility and to decrease the number of single-occupant vehicles, congestion, and air pollution in many parts of the world. This study presents a linear programming model to optimize one-way car-sharing systems for electric cars considering the depreciation costs of chargers and vehicles as well as relocation cost of v...
