Such steps would mean cutting emissions of climate-altering gases by 80% by 2050; and the prospect of that, says Exxon, lies outside "the reasonably-likely-to-occur range of planning assumptions".
A variety of planning assumptions are assessed in this framework, including the developments of power generation, gas supply, together with the growth in load.
A number of assumptions in planning this study were not realized (Table S4 in Additional file 1).
According to Gurnani (1985) and Chung and Kim (1989), the assumption of infinite planning horizon is not realistic due to several reasons such as variation of inventory costs, change in product specifications and designs, technological changes, etc.
The heuristics for modeling included keeping the objective in mind, keeping a list of assumptions, planning for sensitivity analyses, keeping things simple without oversimplifying, and several others.
The reason for the lack of a significant effect appears to be due to the treatment difference being smaller than planned and in the opposite direction to what was anticipated rather than an incorrect assumption of SD at planning.
Nor does our technique require an assumption of restricted plan length or make-span.
Based on DC power flow, the assumptions of the planning model are [27]: (1) Neglect the resistance of transmission lines because the resistance is considerably less than the reactance in high voltage transmission networks.
Both the Greek government and its European and IMF rescuers admit that the country has no hope of tapping private capital markets in 2012, a central assumption of the original plan.
The consistent assumption of people making plans with me is that, since I am a writer and work from home and they have firm adult schedules, I will be available at the times they need.
But under the assumptions of the plan's supporters, that would require a global emissions reduction of almost 80%, a goal impossible both economically and politically.
