Purpose: This paper proposes model-based standard times estimates, using multiple linear regression, nonlinear optimization, and fuzzy systems in four real cases assembly lines. The work includes a description of the models comparison their performance with values obtained conventional chronometer method. These allow estimating without reconducting field studies.Design/methodology/approach: For...

The network Quality of Service (QoS) metrics such as the access time, bandwidth, and packet loss play an important role in determining Experience (QoE) mobile applications. Various factors like Radio Resource Control (RRC) states, Mobile Network Operator (MNO) specific retransmission configurations, handovers triggered by user mobility, load, etc. can cause high variability these QoS on 4G/LTE,...
