Techno-economic analysis of reliable ICT networks and services
Sofie Verbrugge
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?
• Wrap-up and call for action

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

based on detailed view of actual implementation

Open ECMN specification availablepart of FI-ware open specification
Net2Plan tool availableallows to model equipment per year
•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
• Open source Java tool
• Developed at Universidad Politécnica de Cartagena
Detailed process modeling using BPMNexample: network repair process

static roll-out
Value of flexibility = option value
Tutorial paper and presentation available concerning practical use of real options in ICT projects
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
