In supply chain, the ordering strategy is one of the main reasons leading to Bullwhip Effect which can induce inventory's fluctuations or excessive inventory. In this paper, we set up a simulation model on the retailer' s demand-driven supply chain by virtue of system dynamics, in which we compare the inventory's behavior mode based on different ordering strategy, whose simulation results testify...
In this paper we use software engineering methods and Shannon's communication model to investigate computer network architecture. We get a new type of computer network architecture and some significant conclusions. At the first phase of the life cycle of software engineering, that is, requirement analysis, we get a series of unexpected conclusions. For example, a variety of computer network architectures...
Voltage flicker and harmonics are the types of power quality problems that are introduced to the power system as a result of arc furnacepsilas very large power input ratings. In order to propose solutions to minimize the adverse effects, developing an accurate electric arc model has a much needed task. Hence, a new time domain electric arc model is developed on the basis of the conservation of energy,...
