Logistic pattern ‘order-delivery-payment’

July 3, 2011

A method for simplifying the organizational and managerial models could be the use of the self-similarity of the services in the logistic chain. For instance, the order-delivery-payment sequence could be repeated mutatis mutandis as a pattern “Z” in the supply chain, between the consumer A and the service provider B, as shown in the commutative diagram below.


The shorter the duration Δt of a cycle Z  the closer to the final consumer it is accomplished, i.e. it decreases from upstream to downstream, in the time flow direction. The consumer (the client) and the supplier pass from the status (A,B) in the moment t of the purchase order for a certain service or logistic product to the status (A’,B’) in the moment (t+1) of the payment of the equivalent value of the service provided.

According to Zeiger’s lemma, considering the sets A, B, A’, B’, if it is assumed that f is a surjection and g is an injection, then there is a unique application h so that the diagram remain commutative (Zeiger H.P. (1967) Ho’s algorithm, commutative diagrams, and the uniqueness of minimal linear systems, Information and Control, 11).

The clients’ demands, the logistic services and the regulations are more and more sophisticated, which makes the management of the logistic chains be more and more based on knowledge.

However, the strategic role in the planning of the inter-, multi- and co-modality of the transport systems is played by the transport policy which must be developed and institutionalized at the level of the respective authorities.  A strategic scenario for the development of the intermodal transport must be created with a view to making and implementing the strategic decisions under a continuous regime, starting from the information coming from the spot market and from the derivation of the general strategies from an upper level. Thus, there are obtained the organizational and institutional entities that must be established, such as the strategy implementation bodies and the statistic observer etc. They must consider the self-similarity principle between various decision-making levels.
