DETERMINATION OF THE QUALITY INDICATOR OF E-CARGO BIKES IN LOGISTICS SYSTEMS, TAKING INTO ACCOUNT THE SUBJECTIVE ASSESSMENT OF DRIVERS

The article is devoted to the formation of a logistics system for transporting goods using "green technology". The feasibility of using electrically powered vehicles from the point of view of the carrier is proposed to be determined taking into account the subjective assessment of drivers regarding their properties. The quality of an electric cargo bike is determined by their performance. These characteristics are constantly used by drivers of electric bicycles when transporting goods. All indicators of bicycle quality are evaluated by drivers with different levels of significance. Determination of the level of significance for drivers parameters of the quality of the bicycle were carried out by conducting full-scale surveys. The survey was carried out at enterprises engaged in the transportation of goods by electric bicycles. It consisted of a survey of drivers, during which they were asked to indicate the performance characteristics that, in their opinion, affect the quality of use of the bike. To process the results of the survey, the method of expert assessments was used. The results of the processing of the survey results made it possible to conclude on the consistency of experts' opinions. Significant parameters of bicycles were load capacity, mileage on a single battery charge, bicycle weight, number of speeds, number of wheels. The results of the survey made it possible to determine the sum of ranks for each factor. The assessment of the significance of the factors was carried out using the value of this sum. Based on these values, as a result of calculations, the corresponding coefficients of weight of unit quality indicators were obtained. For single indicators, it is proposed to use the ratio of the actual value of the indicator to the maximum. To estimate the weight of a bicycle by a single indicator, it is proposed to use the ratio of the minimum value of the indicator to the actual one. As a result, a comprehensive quality indicator of a cargo electric bicycle was formed. Its use allows you to comprehensively take into account the ratio of real and rational technological parameters, as well as the opinion of drivers about the significance of each parameter. Drivers. Thus, for the first time in the work, an approach to the selection of parameters of electric cargo bicycles is proposed, which differs from the existing ones in that it takes into account the ergonomic parameters of bicycles, determined on the basis of a subjective assessment of their properties.
