Many solutions to cost-sensitive classification (and regression) rely on some or all of the following assumptions: we have complete knowledge about the cost context at training time, we can easily re-train whenever the cost context changes, and we have technique-specific methods (such as cost-sensitive decision trees) that can take advantage of that information. In this paper we address the pro...

This article analyses the conflict between trade values and other values ('trade and ... problems'), such as environmental protection, labour rights or free competition, as It Is addressed by the principal legal devices available to address such conflicts ('trade-off devices') In the dispute resolution context In the European Union, the GATT/World Trade Organization system and In the United Sta...

Every project manager deals with various challenges, and almost all tasks have backup plans to ensure efficient success. Therefore, it is essential manage resources, notably in terms of time, cost, quality, environmental impact, this needs be thoroughly shown. As a result, the adaptive selection slime mold algorithm (ASSMA) proposed for repetitive projects due multiple concurrent instances. It ...

Along with the increased use of water resources, some large conservancy projects began construction to address power supply shortages and control flooding drainage. As investment grows, cycles lengthen, external environmental impacts become bigger, civil engineering project management becomes more complex. The real aim hydraulic-structure model is manage ways delivering on time while maintainin...

A model is developed to minimize the life cycle cost of a system providing availability of services from a constellation of satellites. The model consists of a cost model, and a performance model. The cost model includes the cost of purchasing and maintaining an inventory of satellites and launch vehicles, launch operations, and on orbit operations. The performance model evaluates the availabil...

in the case of hazardous materials management, selected routes for carrying hazardous materials (i.e.,hazmat) have significant effects on locating hazmat distribution centers. since, risk and cost are usuallyconsidered as two main attributes to determine the best routes, optimized locations are sequentially outlineddepending on selected routes. in the present paper, two different approaches of ...

the aim of this empirical study is to explore the trade-off model and pecking order model of capital structure. the investigation is performed using panel data procedures for a sample of 76 firms listed in tehran stock exchange during 2007-2010.the study employs ols regression model in examining the capital structure of firms in iran. the study employs variables reflecting differing theoretical...

This paper draws attention to project trade-offs significance in project management and critically reviews the current state of the knowledge on the elements to be considered and the methods to resolve trade-off decisions. Traditionally the elements to be considered in trade-offs are mainly limited to time and cost and to some extent quality or risk or the well-known Project Triangle. The trade...

This paper develops an economic lot-sizing production model for deteriorating items with time dependent quadratic demand and delay in payments under two levels of trade credit policy. The trade credit policy adopted here is a two-level trade credit policy in which the supplier offers the retailer a permissible delay period M, and the retailer in turn provides customers a permissible delay perio...
