Invited talk DRCN2017Munich, Germany, March 9th 2017

Techno-economic analysissupports investment decisions

Techno-economic analysisis always done in a multi-actor context

Techno-economics analysisdeals with expected market and customer dynamics

Techno-economics analysistakes the impact of uncertain changes into account

Techno-economics analysisneeds to adapt to boundary conditions

BudgetTechnicalPolicyGeography/demographyEtc.

Investment decision based on innovationcan be situated on different layers in the network stack

• What is techno-economic analysis?

• How to make a quick assessment?

• What are appropriate cost models in an investment analysis?

• How to integrate more advanced concepts in an easy way?

• Where to find all information?

Appropriate level of detail/abstractiondepends on available input data and goal of the model

Level of detail

Fractional

Function of driver

Dedicated dimensioning

ProcessesInfrastructure

Fractional cost modelingis on the highest abstraction level

Source: Orange – from FTTH pilot to pre-rollout in France

Determine fraction of overall costs to allocate to different partsbased on previous projects (pilots, other areas, etc)

Function of driver cost modelingis on the intermediate abstraction level

Examples of drivers:

installation length (50€/m)

customer base (1k €/cust)

…

combinations possible

Find the parameter that mainly drives the cost

This is the most common cost modeling approach!

Dedicated dimensioningis on the lowest abstraction level, thus gives most detail

•Planning and evaluation of a multilayer IP-over-WDM network•Goal• Plan and allocate the resources

at the IP and optical layers for a given year• while minimizing the capital

expenditures (CAPEX) cost of the network

Game theorymodels the impact of interaction

36

Game theory is a discipline aimed atmodeling situations in which decisionmakers have to make specific actionsthat have mutual, possibly conflicting,consequences.

Competition has big impactas shown by game theory
