The lift-gas allocation problem with pressure-drop constraints and well-separator routing is a mixed-integer nonlinear program considerably hard to solve. To this end, a mixed-integer linear programming formulation was developed by multidimensional piecewiselinearization of pressure drop functions using standard (CC) and logarithmic (Log) aggregated models. These models were compared by means o...

the task of optimally assigning military ordinance to enemy targets, often termed weapon target allocation (wta) problem, has become a major focus of modern military thought where a cost effective allocation is required without degrading the required kill performance. the paper presents three main weapon allocation techniques namely uniform weapon allocation, first-in-first weapon allocation an...

OBJECTIVE Almost every country in the developed world has a domiciliary oxygen program. Whether recipients meet program criteria has not been rigorously studied. DESIGN Cross-sectional survey. PARTICIPANTS Two hundred thirty-seven patients receiving domiciliary oxygen in the Ontario Ministry of Health Home Oxygen Program (HOP). METHODS A respiratory therapist visited the patients' homes a...

Natural gas is a main source of energy in Iran, and optimal allocation to different sectors crucial, based on realities, geopolitical considerations, national security concerns. In this paper, multi-objective goal programming model developed study the resource various consumption sectors, including household business, industry, petrochemical power plants, injection oil fields, export from Iran ...

The CPM has proven to be helpful only when the project deadline is not fixed and the resources are not constrained by either availability or time. Resource-constrained scheduling arises as a result of problems with the availability of resources. It is necessary to apply the availability of resources into a scheduling process for this reason. The objective of this paper is to present an optimal ...

Energy conservation and greenhouse gas (GHG) abatement have been included in the national development strategy of China, however, the rigidity in command-and-control, absence of market-mechanism and arbitrariness in assignment of abatement burden across regions have caused unnecessary losses in both economic efficiency and social equity. In this paper, we established an Inter-Regional CGE model...

This paper examines the effects of emissions allowances allocation schemes on the extent of the GHG (greenhouse gas) leakage and the contract shuffling. Two allocation methods, grandfathering and the output-based method, are considered. Whereas grandfathering separates future allowances allocation from today’s decisions, the output-based approach links the future awarded allowances to today’s o...
