We consider a problem faced by an airline that operates a number of parallel flights to transport cargo between a particular origin to destination pair. The airline can sell its cargo capacity either through allotment contracts or on the spot market, where customers exhibit choice behavior between different flights. The goal is to simultaneously select allotment contracts among available bids a...

System operators in the electricity industry are required to procure reserve capacity to deal with unanticipated outages, demand shocks, and transmission constraints. One traditional method of procuring reserves is through a separate capacity auction with two-part bids. We analyze an alternative scheme whereby reserves are procured through the energy market using only energy bids, and capacity ...

This paper demonstrates a method to how reserve capacity and cost allocation could be determined in a pool-based and disaggregated market model. The method considers both the spinning reserve and interruptible loads as the operating reserve services. In the proposed market, generators and consumers (including participation of interruptible loads) submit offers and bids to the independent system...

the revenue management concept and techniques are applied to model the coordination of supply chain elements. the fundamental premise of this approach is synchronization of a group of business entities consist-ing of a manufacturer and multiple suppliers to achieve an optimal supply chain capacity plans. the output of the supply chain can be various products and thus it is measured in terms of ...

We study a dynamic procurement environment with capacity constraints where contractors may re-sell part of the work in the subcontracting market. The ability to subcontract is a prevalent feature of many procurement auction markets but its analysis is absent from the literature. We find that this omission has important consequences, since the ability to subcontract has a substantial and nontriv...

We present a new edge-to-edge management technique, called Ping Trunking, that can provide soft service guarantees to aggregated traffic. A Ping trunk is an aggregate traffic stream that flows between two nodes in a network at a rate dynamically determined by a Vegas-like congestion control mechanism. A management connection associated to each trunk is in charge of regulating the user data tran...

the main objective of this descriptive research was to determinate the components related to an expansion of marketing of flowers and ornamental plants. the statistical population of the study consisted of all floriculturists (4920) in tehran, markazi, gilan, khozestan, and razavi-khorasan provinces as well as extension experts. a sample of 234 floriculturists was selected by use of “cluster pr...

A forward reliability market is presented. The market coordinates new entry through the forward procurement of reliability options—physical capacity bundled with a financial option to supply energy above a strike price. The market assures adequate generating resources and prices capacity from the bids of competitive new entry in an annual auction. Efficient performance incentives are maintained...

to measure an unbiased farm-specific efficiency of individual dairy farmers, a shadow-price profit frontier adjusted for market distortion was applied to a sample of 860 iranian small intensive dairy farms surveyed in 2005-2006. this measure was then compared with that of unadjusted measure that assumes undistorted market. a multiple general linear model (glm) technique was applied to the data ...
