SID-02324: Risk Adjusted NPV Task Priority Manager

Status:	Asked	TWiki version:	6.0.2	Perl version:	v5.22.1
Category:	CategoryPlugins	Server OS:		Last update:	8 years ago

I need to manage a group of projects within an organization, prioritizing resources to tasks by their contribution to maximizing the organization's net present value (adjusted for risk). Yeah, I know: No one does it this way. I don't care. It's the right way to manage projects. I have to program it myself.

One of the capabilities I need, in order to implement it, is to have, for each task, a (NPV, Risk) pair where the NPV (not adjusted for risk) is calculated from the NPVs of the tasks that depend on it (chained until you get to the end point -- such as projected sales profit stream).

This involves what might be thought of as a wikisheet construct -- something that I haven't seen implemented outside my own work on MediaWiki. As a 63 year old Perl hack from way back, I take a dim view of all these PHP kids playing on my lawn, but I do admit to installing MediaWiki so that I could implement a macroengineering model for energy and the environment for a guy that co-founded the Energy Information Administration.

It used some MediaWiki features and modules such that, for each input or calculated quantity, I could write a wiki page documenting the quantity such as citations, the formula, etc. These pages would grab calculated values from each other and recalculate only what was affected by changes in other pages. For example:

{{#expr:{{FutureGen Without Sequestration Elex Cost ($/kWh)}}-{{Net Revenue Available For CO2 Payments ($/kWh)}}-{{NH3 Profit Per FutureGen Energy ($/kWh)}}}}
==Model== [[template:FutureGen Without Sequestration Elex Cost ($/kWh)|FutureGen Without Sequestration Elex Cost ($/kWh)]] - [[template:Net Revenue Available For CO2 Payments ($/kWh)|Net Revenue Available For CO2 Payments ($/kWh)]] - [[template:NH3 Profit Per FutureGen Energy ($/kWh)|NH3 Profit Per FutureGen Energy ($/kWh)]]
==Comment== The Bottom Line
"FutureGen Prime" is an enhanced efficiency, near-zero emission version of the FutureGen technology. It requires an [[FutureGen Initial Cost Per Installed Power (dollar/W)|initial investment of approximately ${{FutureGen Initial Cost Per Installed Power (dollar/W)}}/W]] to capture the residual emissions from FutureGen, as well as shipment of all unmarketable emissions back to be buried in their coal mines of origin. Over an industrial learning curve, this investment drops to [[template:FutureGen Plant Cost/Capacity ($/W)|an overall average of ${{FutureGen Plant Cost/Capacity ($/W)}}/W]]. In addition, rather than using air as the oxidizer, air is separated into its constituent gases by liquefaction. The N2 is stored for use in [[Cold gas turbine LN2 power per FG Power|a cold gas turbine for peak power]], with a Carnot efficiency determined by the temperature difference between the boiling point of N2 and the waste heat temperature of FutureGen combustion, which uses O2. Residual gases are marketable products. Since it uses IGCC, hydrogen is available for ammonia synthesis. Both CO2 and NH3 are produced in the ratio required for algaculture and both add to the profitability of electrical generation.
==Notes== nil

Since I know I'm going to have to do some serious programming to get my project management features I'm revisiting Twiki after 'lo these many years, and would like to know what my best strategy should be. Assuming I don't I team up with an existing project management plugin project, what plugins are most likely to enable the development of such a new project management plugin?
