Scope of the transport and logistic system
In order to identify and evaluate performance improvement initiatives taken within transport and logistics there one has to define the system boundary of the assessment. NTM use the below presented hierarchic model in order to describe various layers of transport and logistics activities.
The rationale for this model is that provided transport and logistic services on top level impacts the societal planning and development regarding possible options for location of living, industry, recreation etc., Societal planning also impacts transport services. Overal the modell includes interrelations between all layers.
Measurement and measures among NTM members are commonly linked to the transport, traffic and propulsion systems. Other interlinked sub systems may be equally important to accomplish sustainable transport and logistics, but these are presently not our primary focus. Partly because of lack of solid and credible data.
A key element in change management is the ongoing interplay between the existing transport actors. For NTM these are the transport buyer and a transport supplier. From an outside perspective this may look simple and obvious. In reality, the market situation for transport and logistics is very complex and includes many layers of actors that has a significant influence on the actual transport solutions.
Another key pillar of transport and logistics is the existence of the four modes of traffic. In addition, all modes of traffic are often used in various intermodal solutions. Individually they commonly operate under very different conditions.
