Purpose: Purpose of this paper: Actually, in automotive industries one of the most important activities in product design is the evaluation of various events (i.e. crash events) using FEM simulation; in this context, software independence, that means to obtain the same simulation results on the same car-model using different FEM solvers, will be useful for reducing virtual prototyping time and consequently Time To Market. Design/methodology/approach: Development of a software-indipendence translation method is the aim of this work, which is an input data translation by a methodology independent of the FE calculation environment and allows reducing drastically the product development time. This methodology will be developed writing ad hoc a routine in Matlab language, that carries back in LS-DYNA environment the cards written in RADIOSS environment, helped by TextPad editor and completed by pre-processor Hypermesh. Findings: The translation could be executed using the pre and post-processor Hypermesh and the RADIOSS model card manual correction, but this way to operate increases greatly the Time To Market, although today is the only method used in the most important Italian automotive industry. Research limitations/implications: A Software independence in Virtual Prototyping could help to accelerate several processes. The need to reduce costs and to increase quality is nearly obvious. Practical implications: Most of crash simulation models are developed in RADIOSS environment, but the LS-DYNA environment potentialities exploration has increased the simulations demand using LS-DYNA software; therefore the development of a translation method like that meets this requirement. Originality/value: For product designers, the development of a translation methodology, that allows to carry back in a software environment the Know How developed for another software environment, will be very useful (We’ve to remind that often many design tasks of a project are made in outsourcing way).

Purpose: What determines the correcttness of industrial company's functiioning on the market is technological process. In order to improve it continuously the priority should be technology, technology management and controlling. Design/methodology/approach: by means of this model one can analyzy the choosen technological processes for the sake of efficiency criteria. They describe following relationships: operation-material, operation-machine, operation-man, operation-technological parameters. Findings: This analisis shows hypothetical technological processes on production of typical pieces for machines. One has also taken into account nonmaterials parameters of technological process. They are resulting from applied sampels and projecting of the technological process. Practical implications: Thanks to the created aplication we can analyze efficiency of technological process in aspect of nonmaterial values. By the use of neural networks we can verify particle indicators of process operation quality, evaluate the process efficiency, which can constitute the optimization basis of particular operation. Originality/value: Data effecting from this analisis allowed to optimize the technological process. They estimate influence of the analyzed parameters on the whole process and optimizethe conducting of any process.

Purpose: Of this paper was to present the methodology of analysis of the productive processes with application of value analysis and multi-criterion-analysis which allow to evaluate the technology and organization of the productive processes. Design/methodology/approach: Presented in the paper methodology of evaluation of the productive processes is based on analysis of activities in the productive processes and their characteristics with reference to created value in the productive chain. Findings: The paper presents elaborated by the author methodology and computer application for application in the chains of the productive processes. Research limitations/implications: Presented methodology allows to evaluate effectivity of the productive chains connecting aspects of the management and economics of the process. Practical implications: Presented methodology was used in analysis of the productive chains and their effectivity, and also as a benchmarking instrument. Originality/value: The paper presents originally elaborated computer application for the value added analysis in the productive chains.
