In many circumstances, the quality of a process or product is best characterized by a given mathematical function between a response variable and one or more explanatory variables that is typically referred to as profile. There are some investigations to monitor auto-correlated linear and nonlinear profiles in recent years. In the present paper, we use the linear mixed models to account autocor...

This paper describes a method for conducting worth feasibility evaluation (WFE) in innovative product development. The method uses an enhanced quality function deployment matrix to identify the effects of multiple, possibly conflicting, engineering solutions on the product attributes being developed. The WFE allows product developers to assess whether their proposed engineering approach to exec...

Software Product Line Methods (SPLMs) have been continuously gaining attention, especially in practice, for on one hand, they address diverse market needs while controlling costs by planned systematic reuse in core assets development (domain engineering), and on another hand, they reduce products’ time-to-market, achieving a certain level of agility in product development (application engineeri...
