Abstract
The transportation of passengers by railroads is a dynamic process because setting, wherein the process takes place, undergoes continuous changes observed at technical, technological and transportation process planning levels. Every passenger has diff erent needs and aims and can aff ord diff erent possibilities. Th erefore, the conception of quality diff ers in each individual case. In order to be able to plan a railway trip process in a proper manner, it is important to become familiarized with passenger needs and preferences and eliminate any existing defi ciencies. To this end, it is reasonable to conduct passenger surveys. Th e paper provides an affi nity diagram of railway transportation quality factors, the elements whereof correspond to the structure of the survey questionnaire. For determining the level of the quantitative signifi cance (weight) of indicators, there was applied the method of Analytic Hierarchy Process (AHP) developed and introduced by the American scientist T. Saaty. Th e scope of research work carried out by the authors covered the determination of the highest eigenvalue, the compatibility ratio, the concordance correlation coeffi cient, the estimated and critical value of chi-square values (the examples of estimations are presented in the paper) as well as the classifi cation and processing of the surveyed data on passenger questionnaire and the analysis of respondents’ opinion. Th e closing part of the paper presents conclusions drawn based on the fi ndings of the survey and respective recommendations for quality improvements in passenger transportation by Lithuanian railways.
 
Keleivių vežimo geležinkeliu procesas – dinamiškas procesas, nes aplinka nuolat kinta techniniu, technologijos ir vežimo proceso organizavimo lygiu. Kiekvienas keleivis turi skirtingus važiavimo poreikius ir tikslus, skirtingas galimybes, todėl ir kokybės samprata skiriasi. Norint tinkamai organizuoti kelionę traukiniu, būtina žinoti keleivių norus, pageidavimus, šalinti esamus trūkumus. Tam tikslinga atlikti keleivių apklausą. Darbe pateikta keleivių vežimo kokybę rodančių veiksnių sieties schema, kurios elementai atitinka apklausos anketos struktūrą. Rodiklių kiekybiniam reikšmingumui (svoriams) nustatyti pritaikytas amerikiečių mokslininko T. Saaty porinio lyginimo metodas (Analitic Hierarchy Process). Nustatyta didžiausia tikrinė reikšmė, suderinamumo santykis, konkordancijos koeficientas, apskaičiuotasis χ2 ir kritinis χ2kr skirstiniai. Pateikti jų skaičiavimo pavyzdžiai, susisteminti ir apdoroti anketiniai keleivių apklausos duomenys, išanalizuota apklausoje dalyvavusių keleivių nuomonė. Straipsnio pabaigoje pateikiamos tyrimais pagrįstos išvados ir rekomendacijos keleivių vežimo (kelionių traukiniu) Lietuvos geležinkeliais kokybei gerinti.
