This paper tries to incorporate both Chung and Huang (2003b) and Huang and Chung (2003) to develop the buyer’s inventory model. That is, we want to investigate the buyer’s optimal cycle time and optimal payment time under supplier’s trade credit policy and cash discount policy. Mathematical models have been derived for obtaining the optimal cycle time and optimal payment time for item under sup...

The decade prior to the Great Recession saw a boom in global trade, including a rapid rise in commodity prices, trade volumes, and, consequently, in the cost of transporting goods around the world. At the same time currencies of commodityexporting currencies appreciated, boosting the carry trade profits in foreign exchange markets. The onset of the Global Recession led to a sharp reversal in al...

In this paper, we study the effect of insulating and non-insulating cost allocations on internal trade in a model of incomplete information. From the perspective of firm-wide profit, the allocation scheme that results in the least amount of rationing (forgone profitable trade) is the optimal one. If one thinks of internal trade as a form of cooperation, one might expect non-insulating allocatio...

In pre-industrial Europe, rising productivity both in agriculture and in industry depended on the expansion of trade, and the expansion of trade depended in turn on the reduction of trading costs. An important component of trading costs—for some goods the most important—was the cost of transportation. This had two elements: the cost of predation and the cost of carriage. This paper examines the...

In project scheduling, it is feasible to reduce the duration of a project by allocating additional resources to its activities. However, crashing the project schedule will impose additional costs. Numerous research has focused on optimizing the trade-off between time and cost to achieve a set of non-dominated solutions. However, the majority of the research on time-cost trade-off problem develo...

Security critical systems development needs to integrate both project and product risks assessment into the development. Such systems need to balance time to market constraints, cost demands, functional requirement, as well as security requirements. This advocate the use of techniques that support costeffective and risk-driven development. The aspect-oriented risk-driven development (AORDD) fra...

Real time artificial intelligence (AI) systems are required to respond within a given deadline, or have optimal response times. While some researchers have addressed the issue of planning under deadline constraints, there has been very little research towards optimizing the response time of problem-solving methods. The costs for a response consists of the cost to plan for a solution and the cos...

in this paper, we describe our implementation of an interior point algorithm for large scale systems. first we identify system with small and medium methods convex optimization, then we use interior point method for identification. finally we offer an interior point method that uses nonlinear cost function and see that we achieve a good trade-off between error and cpu time. actually, in this pa...
