Investment activities related to improving the quality of transport services should be based on the following basic principles, focused on compliance with the requirements of a systematic approach, universal values and taking into account the conditions of market relations:

The principle of priority of social and environmental effects, which means that when evaluating the effectiveness of transport projects, it is necessary to take into account, first of all, social and environmental effects, while simultaneously checking them according to safety and environmental criteria.

The principle of an integrated approach, which determines the need to take into account when determining the effectiveness of all possible costs and resources in system quality management, as well as all the emerging results (consequences) of the creation and use of products and transport services provided (results of the organization’s activities) at all levels of management, both in transport and beyond.

The principle of ensuring the minimum impact of incompleteness and unreliability of available information, which means reducing its negative impact on quality management decisions and the results of the entire socio-economic system to the possible minimum.

The principle of comparability of results, which means the need to ensure comparability of the achieved social, environmental and economic effects due to the functioning of the quality management system according to the following criteria:

– social consequences;

– environmental consequences;

– the volume of meeting the needs of developers and transport companies;

– volumes and ranges (interchangeability) to meet the needs of cargo owners;

– a time factor, bringing the effects of different times to the conditions of their commensurability and value by a certain time;

– uncertainty of risks associated with the achievement of effects.

Assessment of the effectiveness of transport and logistics service management should be carried out by comparing data with and without measures taken and implemented.

The principle of mandatory accounting and analysis of costs for quality assurance and management. Without the implementation of this principle, it is almost impossible to determine the economic efficiency of a transport project.

In addition to these rules for determining effectiveness, a number of other principles should be taken into account:

– progressiveness and maximum effect, i.e. when justifying the effectiveness of an event, preference should be given to the one that allows you to get the greatest value of a positive effect;

– the time factor, which makes it mandatory to take into account changes in effects over time, the cost of multi-time results and costs with a preference for faster results and later costs;

– the effects obtained only from the measures under consideration, that is, past or present, but unrelated results and costs should not be taken into account;

– multi-stage determination of the effectiveness of quality management, which means the need to calculate (with different depths) at each stage of development, implementation and implementation of measures to improve the system of transport and logistics services;

– quantitative accounting of the impact of uncertainties and risks of the implementation of quality management measures.
