Features of postal item and their impact on transit time parameter

Abstract

The paper is focused on relation between transit time of postal items and selected discriminant mail characteristics within their modes modelled by system of test postal items, namely end-to-end services for single piece priority mail. They are designed as sample of postal items proportionally to real mail flows and measured in context of their transit time. Each test item is defined by its set of characteristics and these are divided to certain modes to identify specific features of item. These discriminant mail characteristics (DMC) can have influence on technological processing of postal item and thus impact measured transit time parameter. The main objective of this paper is to research influence of concrete mode within particular DMC on transit time parameters following from modelling of test samples. Mentioned relation could vary with form of logistic network, capability of nodes processing items and systems of delivery. Analysis of potential dependences is based on data and indicators of period with usual and typical course of panelist behavior by sending and receiving items, thus without seasonable anomalies. The results should partially analyze consistency of measuring system, which reflects postal transport network efficiency. Naturally it could help to find relevant ways to improve accuracy and exploitation of measuring system within postal services quality management.
