H-ergo, a concept of light electric vehicle devoted to personal mobility, will here be presented. H-ergo is a low-noise, user-friendly, zero-emission vehicle, with a pleasant style. Its main features include high payload/vehicle mass ratio, electric energy supplied either by batteries or by fuel cell, ergonomic style in order to transport a driver or a person whit mobility problems, chassis design to minimize cost of production, variable wheelbase (through electric actuator). The paper presents the main ideas on which the vehicle design was based and summarizes the most important results obtained.

The survey we are going to present comes from the request to optimize an industrial product pre-assembly chain. Considering the good results we obtained, we’ve built up a methodology and several instruments dedicated to assembly chains where the human presence is still important. The surveyed assembly line was made of an ever-moving conveyor belt with fixed workspaces along it. The requested targets were as follows: Decrease the number of waste products and pre-assembled product fixes by the end of the line; Improve workers’ comfort and efficiency; Improve assembly time by leading the line to the saturation point; Decrease raw materials employ (fixing tapes, adhesives, etc.) There are many aspects to analyze (human factor, layout, equipments, work organization,…) but they are all linked to each other, as well as there are many factors, linked to each other, that can be changed or modified in order to reach the target.

The research's scope is to create a method for the definition, analysis and engineering of effective solutions for the ergonomic improvement in transportation field, with particular reference to new security apparel. In order to ensure success of analysis and of the possible solutions proposed, we believe it is necessary to adopt a line of procedure that involves the participation and work division of both drivers staff and that of the technicians and the maintenance workers.
