Although lot streaming scheduling is an active research field, lot streaming flexible flow lines problems have received far less attention than classical flow shops. This paper deals with scheduling jobs in lot streaming flexible flow line problems. The paper mathematically formulates the problem by a mixed integer linear programming model. This model solves small instances to optimality. Moreo...

I T IS a well-recognized fact that the theory of fuzzy sets and systems, for the last four decades after the seminal paper by Professor Zadeh [1], has demonstrated its remarkable ability to go beyond conventional information representation. It resulted in a wide range of new formulations of practical problems, such as fuzzy control, fuzzy clustering and classification , fuzzy modeling, and fuzz...

Congestion control of real-time streaming a video clip or film across the Internet is vital, as network traffic volatility requires constant adjustment of the bit rate in order to reduce packet loss. Traditional solutions to congestion control are prone to delivery rate fluctuations and may respond only when packet loss has already occurred, while both fluctuations and packet loss seriously aff...

Quality of Service (QoS) of IEEE 802.11e is currently under research for the upcoming multimedia applications over broadband wireless networks. IEEE 802.11e is a contention based channel access function that uses the enhanced distributed channel access (EDCA) techniques. EDCA statically resets the Contention Window (CW) after each successful transmission. This article discusses a fuzzy logic ap...
