This paper presents a multi-stage approach toward the robust classification of travel-modes from GPS traces. Due to the fact that GPS traces are often composed of more than one travel-mode, they are segmented to find sub-traces characterized as an individual travel-mode. This is conducted by finding individual movement segments by identifying stops. In the first stage of classification three ma...

In this paper a mixed integer lineal programming (MILP) approach is proposed for the scheduling of multiple dissimilar orders in a non-continuous serial production environment. In this context, different products must be produced in several stages, in which a single machine is chosen per stage to accomplish the production of each order. This work has been carried out in a manufacturing company ...

Roughly speaking, there is one main model of pattern recognition support vector machine, with several variants of lower popularity. On the contrary, among the di erent multi-class support vector machines which can be found in the literature, none is clearly favoured. On the one hand, they exhibit distinct statistical properties. On the other hand, multiple comparative studies between multi-clas...

in this article, modeling and optimization of power consumption of two–stage compressed airsystem has been investigated. to do so, the two – stage compressed air cycle with intercooler offajr petroleum company was considered. this cycle includes two centrifugal compressors, ashell, and a tube intercooler. for modeling of power consumption, actual compressors isentropicefficiencies and intercool...

We study algorithmic problems in multi-stage open shop processing systems that are centered around reachability and deadlock detection questions. We characterize safe and unsafe system states. We show that it is easy to recognize system states that can be reached from the initial state (where the system is empty), but that in general it is hard to decide whether one given system state is reacha...

The pull-type manufacturing system is known for its need for a frozen schedule, balanced workload and inability to handle fluctuations in demand. But today’s research and development are addressing the ways to handle a pull-type system to accommodate greater fluctuations. One approach is to design the system with greater routing flexibility in that flexible machines and multiple part types are ...
