A comprehensive thermodynamic study of a multigeneration system, based on a heat recovery unit, an organic Rankine cycle (ORC), an ejector refrigeration cycle, a domestic water heater and a proton exchange membrane (PEM) electrolyzer, for residential applications is undertaken to produce multiple commodities, in terms of power, heating, cooling and hydrogen.
Meanwhile, small errors of multiple commodities demonstrate that models in this paper works in multiple commodities.
This paper addresses a multi-stage and multi-period supply chain network design problem in which multiple commodities should be produced through different subsequent levels of manufacturing processes.
Commodity index funds -- new speculative vehicles that allowed fund managers to bet on "baskets" of multiple commodities all at once -- jumped in popularity, growing from $15 billion in 2003 to $200 billion in 2008, according to a 2009 report by the Senate Subcommittee on Investigations.
This problem occurs in many contexts where multiple commodities (e.g. flow demands) share the same resources, such as transportation problems, bandwidth allocation problems, and flow scheduling problems.
However, some of the HS-codes, even in the six-digit category, integrate multiple commodities, including instances where, among the many commodities, only one contains the metal(s) in question.
The results of our analysis can provide guidance to investigators when forming hypotheses about contaminated food sources during outbreak investigations, and in suggesting the likely contaminated ingredient in outbreaks associated with foods containing ingredients from multiple commodities.
Xstrata said in its statement that a "combination would create a premier portfolio of operations diversified across multiple commodities and geographies".
In this paper, we introduce a Green Intermodal Service Network Design Problem with Travel Time Uncertainty (GISND-TTU) for combined offline intermodal routing decisions of multiple commodities.
The vehicles can deliver any set of commodities and multiple visits to a customer are allowed only if the customer requests multiple commodities.
In this paper, we study a supply chain network design problem which consists of one external supplier, a set of potential distribution centers, and a set of retailers, each of which is faced with uncertain demands for multiple commodities.
