car-following models, as the most popular microscopic traffic flow modeling, is increasingly being used by transportation experts to evaluate new intelligent transportation system (its) applications. a number of factors including individual differences of age, gender, and risk-taking behavior, have been found to influence car-following behavior. this paper presents a novel idea to calculate the...

This chapter deals with a mathematical model which gives an optimal production schedule in demand declining market if production system is imperfect (i.e. at any random time during production period machine shifts from 'in – control' state in to 'out – of control' state). This is a study about economic production in an imperfect production system. The imperfect production system means, a system...

This paper looks at differences in spatial and temporal variation of rice yields in China and Brazil. We find that rice yields in China have converged over time and that rice production has become more and more homogeneous. In contrast, rice yields in Brazil have diverged over time, primarily due to variations in upland rice yields. Three hypotheses are put forward to explain the different beha...

Environmental strains are causing consumers to trade up to greener alternatives and many brown products are losing market coverage to premium-priced green rivals. In order to tackle this threat, many companies currently offering only brown products are contemplating the launch of a green product to complement their product portfolio. This paper provides strategic insights into and tactical rami...

The foundation of all plant production systems is the effective, efficient and dependable means of nutrient delivery to the plant. The nutrient delivery system directly influences the physical components and the plant culture tasks of the plant management technique within the controlled environment agriculture system. The nutrient delivery system can be described in terms of its mechanism for w...

2 Architecture In this paper, firstly we discuss the architecture of a flexible automated production system under which all components are well-modulized. Then, a solution, EMFAK(Event-driven Multi-tasking Flexible Automation Kernel) is proposed to speed up the construction of system control. At last, a flexible assembly system using EMFAK is described to show how to apply it to a real flexible...

Design and implementation of data warehouses remain delicate tasks which are led by experts. Nevertheless it would be interesting to allow the users to define and to build themselves their system through a simple and flexible process. In particular, in the field of production systems, exists the need to integrate data from various sources and to analyze them in order to extract knowledge for op...
