Interest has been raised by the recent identification of potential savings through collaborative planning in logistics operations. Even though substantial savings can be realized, two key questions exist: (i) how should potential savings be divided among a group of collaborating companies and...

We study the dynamical behavior of a single vehicle moving through a sequence of traffic lights on a single-lane highway, where the traffic lights turn on and off periodically with the synchronized or green-wave strategies. The dynamical model of the vehicle controlled by traffic lights is...

We study the dynamical behavior of elevators in the morning peak traffic. We present a stochastic model of the elevators to take into account the interactions between elevators through passengers. The dynamics of the elevators is expressed in terms of a coupled nonlinear map with noises. The...

We present the dynamical model of the multiple production lines composed of M parallel and u series machines. We extend the single-series production line model to the multiple production lines. We study the effect of the multiple lines on the dynamical behavior of the production process. We...

We study the dynamical behavior of a single vehicle moving through a sequence of traffic lights, where the vehicle speeds up to retrieve the delay induced by traffic lights and the traffic lights turn on and off periodically on a single-lane highway. The dynamical model of the vehicle controlled...

We study the dynamical phase transitions in the elevator traffic during the morning peak period. We apply the coupled nonlinear map model to the dynamics of M elevators. We investigate the effect of elevator's number M on the dynamical transition. It is shown that the dynamical transitions occur...

We present the stochastic model of the supply chain composed of u series machines and buffers. Each machine has an adaptation time (delay) different from the other and each buffer has a capacity of storage different from the other. We extend the deterministic supply chain model to the stochastic...

We study the dynamical behavior of a few shuttle buses that pass each other freely on a cyclic route. We present a discrete dynamical model of the shuttle buses to take into account the interactions among buses and passengers. It is found that the bus exhibits a chaotic motion by the free...

We study the dynamic behavior of an elevator induced by a periodic inflow of passengers. An elevator schedule is closely related to the dynamics. We present the modified circle map model for the dynamics of the elevator traffic. The motion of the elevator depends on both loading parameter and...
