Process integration has become more and more important in today's world where companies' supply chains have become more complex. Companies around the world are beginning to realize the importance of integrating their supply chain business processes to achieve fulfillment excellence....
Retailers collect information regarding consumer purchases on a transactional basis. This data is not completely being leveraged by manufacturers in the footwear and apparel industry to increase on-shelf availability. However, certain apparel and consumer products companies have developed...
As companies become more global and begin to outsource manufacturing and other services, the uncertainty in the supply resource increases. Demand uncertainties increase as these same companies expand into new countries to serve new customers. The globalization of business has created problems...
As required by the WTO accession, China is opening its logistics industry to international logistics companies. What are these companies' strategies in the China market, and how are Chinese domestic logistics companies responding? The author interviewed four executives in charge of China...
Many firms worldwide have adopted the process of Sales & Operations Planning (S&OP) process where internal departments within a firm collaborate with each other to generate a demand forecast. In a collaborative demand planning process buyers and sellers collaborate with each other to generate a...
In the consumer products industry, retail chains and manufacturers run promotions to maintain consumer and brand loyalty. The two major issues in planning and executing promotions are to accurately forecast demand and to control Out-of-Stock at the shelf. This thesis addresses both these issues....
In this paper, we study the effects of intelligent control mechanism on multiple-vehicle collision induced by a sudden stop. The control motion of following vehicles is extended by introducing their velocity relative to the braking one into the dynamic models. We study the dynamic process of...
In this paper, traffic states and jamming transitions on two-lane highway including a bus are studied by using a car following model with a calibrated optimal velocity function. We derive a new flow-density diagram with four distinctly separated traffic states, which is different from that of...
In this paper, we investigate the CO2 emission in a traffic flow mixed with multi-class vehicles by use of an improved optimal velocity model with different vehicles. We explore numerically the dependence of the total CO2 emission rate and the additional CO2 emission on the variation of the...
