It has been hard to model a crowd evacuation process considering different walking abilities using a synchronous cellular automaton. That is because the cross and the overlaps of routes have to be taken into consideration and the conflicts resolution between pedestrians is more complex. However,...

An existing cellular automaton evacuation model is modified to simulate an evacuation experiment conducted in a classroom with obstacles. In the modified model, the impact of the occupant density around exits on human behavior in evacuation is considered. The simulation and experimental results...

People prefer to walk on the right-hand side of the road for physical and social reasons. In this paper, pedestrian counter-flow in a channel is simulated with the Cellular Automata (CA) Model, with focus on right-preference. Two types of pedestrians are taken into account, walking leftward and...

As an extension of the Asymmetric Simple Exclusion Process, the floor field cellular automata model has its specific advantages in reproducing crowd self-organized phenomena, embodying individual characteristics and reducing the computing complexity by translating the long-ranged interaction to...

We study the risk-averse newsvendor model with a mean-variance objective function. We show that stockout cost has a significant impact on the newsvendor's optimal ordering decisions. In particular, with stockout cost, the risk-averse newsvendor does not necessarily order less than the...

Sanctions are used ubiquitously to enforce obedience to social norms. Recent field studies and laboratory experiments have demonstrated, however, that cooperation is sometimes reduced when incentives meant to promote pro-social decisions are added to the environment. Although a variety of...

The authors quantify the benefits of a newly introduced logistics product, day-definite Full Container-load (FCL), in terms of its cost reduction relative to other existing products – regular FCL and airfreight, from the perspective of a logistic manager in an intercontinental supply...

Saving rates and household investment in stocks and business equity are all increasing in income and wealth. Introducing subsistence consumption to a common-across-households Epstein-Zin-Weil utility function is up to a quantitative explanation, in the context of stan- dardized parsimonious...

Surface cover degree, monthly variation of topsoil water content, loss of soil and nutrient in alfalfa-corn intercropping, strip rotation cropping and corn monoculture were studied in this paper. Then soil and water conservation effect of these planting modes were compared. Results showed that...
