We consider optimally coordinated freeway traffic control for networks containing bottlenecks with capacity drop and hysteresis behavior. Due to the multitude of traffic jams, and the spatial and temporal relationships between control actions and traffic behavior, this problem is not as straightforward as for local control. The order in which the measures are applied may be relevant, or it may ...

This paper introduces a multi-lane hybrid theory that treats lane-changing as temporary blockages, because this is what is physically observed in reality. For maximum accuracy lanechanging vehicles are modeled as discrete particles endowed with limited acceleration capabilities that interact realistically with the multi-lane continuum stream. This discrete-continuum (hybrid) setup is parsimonio...

Due to the multitude of traffic jams, and the spatial and temporal relationships between control actions and traffic behavior, this coordinated control problem is not as straightforward as for local control.

There is a tough competition in the furniture sector like other sectors. Along with the varying product range, production system should also be renewed on a regular basis and the production costs should be kept under control. In this study, spring mattress manufacturing line of a furniture manufacturing company is analyzed. The company wants to increase its production output with new investment...

This work presents that global time (a.k.a. time-of-day or coordinated universal time – UTC) is essential in maximizing user perceived quality of service, while eliminating both switching bottlenecks — critical in very high capacity network core — and communications link bottlenecks — at the low speed access (e.g., wireless and DSL). Global time obtained, for example, from GPS (Global Positioni...

Process flexibility, whereby a production facility can produce multiple products, is a critical design consideration in multiproduct supply chains facing uncertain demand. The challenge is to determine a cost-effective flexibility configuration that is able to meet the demand with high likelihood. In this paper, we present a framework for analyzing the benefits from flexibility in multistage su...

In the side constraints. Profiling the solving process of instances having numerous side constraints shown bottlenecks in lonely and capacity that were responsible of a high computation time. The implementation of lonely has been modified to substitute the set-based disjoint constraint by an equivalent that directly manage two lists of integer variables. As a result, the set variables and the c...
