In this paper, first we study the kanban systems; then we analyzes the models of kanban systems, include simulation models and Markov chain models ; finally, we develop a mathematical optimization model that addresses a mufti-item, mufti-stage network for application to general supply chain systems. The dual-type kanban control system is adapted to plan and allocate production and delivery throughout the supply chain system. The objective is to minimize the operating cost and inventory holding cost.展开更多

Recently, this static advertisement model will not be able to attract people’s attention more and more. Moreover, the static information content of advertisement system is limited because of the layout shown size. It can not also fully demonstrate the information content of advertisement system. In this paper, we develop a digital interactive kanban advertisement system using face recognition methodology to solve these problems. The system captures the person’s face through the camera. The digital advertisement content size is relevant by the person and camera observation locations. In this paper, we adopt the Adaboost algorithm to judge people face, and the system only need to grab the position of the face. The system doesn’t built expensive and complex equipment to reduce the system cost and enhance the system performance. This system can also achieve the same similar digital interactive advertising effectiveness.展开更多

The model of a Kanban system based on production processes is established by examining the relationship among the set-up time, the amount of work in process （WIP）, the capacity indicated by a Kanban, and the takt-time ratio. A novel method for optimizing performance on the premise of no stockouts is proposed. Empirical results show that the amount of WIP is reduced remarkably after optimization.展开更多
