The economical sustainability and the integrity of oil field equipment depend on the choice of the best material for the working conditions. In oil wells, many environmental corrosion phenomena take place and affect the structural integrity of metallic parts and equipment. In order to investigate material properties in presence of corrosive environments and applied stresses, many laboratories have arisen and many experimental techniques have been developed and setup in order to collect data about the behaviour of corrosion resistant alloys. Available data are traditionally gathered into text files which are difficult to analyze and process since a widespread commercial software does not exist for automated data processing and reporting. Each laboratory has to develop their own tools in order to perform the data post processing for stress corrosion experiments. In this paper, the Axiomatic Design method has been employed in order to develop a custom software for data post processing of the stress corrosion tests. The application of the Axiomatic Design has a key role in defining the software architecture, avoiding useless solutions and improving code optimization from the earliest phases.

The Iterative and Participative Axiomatic Design Process (IPADeP) deals with the early conceptual design stage of complex mechanical assemblies. It provides a systematic approach based on the theory of Axiomatic Product Development Lifecycle and aims to minimize the risks related to the uncertainty and incompleteness of the requirements, considering that the requirements will be refined and completed during the process. IPADeP has an iterative nature and is focused on the experience of the people involved in the design process. The functional requirements and the design parameters are conceived through brainstorming sessions and the concept selection is performed involving several experts through a Multi Criteria Decision Making technique. IPADeP has been adopted as methodology to address the early conceptual design stage of a subsystem of the DEMOnstration fusion power plant: the divertor cassette-to-vacuum vessel locking system. A first iteration was performed, resulting in the selection of a "high level" rough solution. According with IPADeP this paper presents an improvement of this solution, performing a new iteration of the process, since the system is ripe to proceed with the decomposition and zigzagging to the second level and new requirements are coming in from the development of the interfaced systems. © 2015 The Authors.

Competition in the air transport market in recent years has prompted companies to search for products and services increasingly innovative and, at the same time, the decrease in development timing and the creation of resources devoted to the study of original technical solutions. One emerging important issue is to facilitate air travel for people with disabilities, elder and dependent people, setting the primary objective of preventing the emergence and spread of new barriers. This aspect is important both for the introduction of several mandatory requirements (rules, laws and regulations) and the increasing market share of this people category due to the aging of population. In this paper it is analyzed the study of the flow of PRM (Passengers with Reduced Mobility) departing, arriving and transiting through an airport terminal. The specific case study is based on the management process of passengers with special assistance for a major Italian tourist airport. The Axiomatic Design method is used to link the customers needs with all the process elements and boundaries: the infrastructure aspects, the limits imposed by security and the availability of appropriate resources (personnel and equipment). Finally some improvement suggestions are made to optimize the passage through the terminal and to ensure full accessibility of the considered environments.
