Modelo para avaliar o comportamento dinâmico da agregação de serviços no contexto de PSS

Abstract

Abstract : The Product-Service System (PSS) is characterized by adding value to the product by association services. In these dynamics systems acting feedback information structures, time lags and nonlinearities. So specific performance conditions this association cannot be addressed by the development process or the contemplation without the evaluating dynamic behavior can trigger unfavorable events in system behavior over time. Therefore, this research aimed to "establish guidelines for orientation of product development efforts by evaluation of the dynamic performance of the aggregation a service module to the product into PSS context." The survey data are secondary in nature and collected in specialized literature through a structured process. With this, the bibliographic reference portfolio has built seventeen articles. The intervention instrument "Dynamic Systems" was used for processing. Three main subsystems were comprised by study: production, service provision and consumption. In describing the system context were explained and associated the main factors and highlighted the feedback loops that give the nonlinearities of the system behavior. This feedback loops are: production control, service provision control, control of product quality, control of service quality, process losses and waiting losses. The system structure was defined in proposed model, as well as entered the variables and enabled the mathematically integrating of constants and variables. The impact of unfavorable conditions in model behavior was estimated with simulation process. Thus four basic guidelines for the development activity of the product were presented as a proposed for solving the research problem. These include: strengthening the integration of actions aimed at consumer satisfaction, strengthen the integration of actions directed to the ease of obtaining the value, strengthen the integration of actions aimed at ease of consumption value, and strengthen the integration of actions aimed at controlling and operation of production and value addition.
