On the optimum structure of the hierarchy in an organisation
No full text[[abstract]]Using the character of organizations and the elementary results of queueing theory, a quantitative model of the hierarchy is presented. Its aim is to maximize costs, which are the sum of wage costs and costs caused by delays in decision making. With this model, the sensitivity analysis on key variables of the optimum structure is concretely discussed
Qnew-Video Course Consultative System
No full text[[abstract]]QNew is different from the common Internet video, for it shares the readers with its curriculum self-timer videos. It has the spirit of the open textbook-assisted learning. It also focuses on the uploading, sharing, and expansion of the users’ information. Typically, 5 to 10 minutes is the limit, as long as the teachers and students have finished registering, they can upload their videos of teaching. Website platform is composed of the sub-platform of course classification and message board, which furnishes the teachers and students with the service of Internet Hit.. QNew is the website mentioned in this article, and after its full development, it will not only become one of the departmental remedial resources, but also as an interdisciplinary and inter-campus teaching platform

[[alternative]]從認知觀點設計一個以圖像為主的人機介面
No full text[[abstract]]Icons are often used to represent objects as the Human Computer Interface (HCI). Historically then; have been numerous approaches to the design of HCI from the technology driven approaches. This paper attempts to discuss some issues which are related to icon-based HCI design from the cognitive aspects. The population stereotypes regarding the meaningfulness of icons are functions of the exposure of the relevant content domains. Through the resolution of cognition, the relationships between stimuli icons and experience factors could be set. Furthermore, the classification and structuralization of iconic source would be made
Two-stage production plan of probabilistic market demand with unreliable machines and obtainable working hour capacity
No full text[[abstract]]The Two-Stage Production Plan (TSPP) Model for reaching the optimal production rate of each stage undergoing the considerations of probabilistic market demand, future obtainable working hour capacity of each stage and unreliable machines is proposed in this paper. It is exactly applied to evaluate the optimal production speed in reducing the risk of future uncertainty. In addition, the time interval of production, maintenance cost of an unreliable machine, transaction, penalty, holding costs, sales price and the machine reliability are taken into considerations. Moreover, sensitivity analyses for the key variables of optimal solution are also presented. Accordingly, this study effectively provides a dynamic tool capable of controlling the production plan (rate) at any time for the production planner with great insight
A dynamic optimal investing model for international reserves management
No full text[[abstract]]The major purpose of this paper is to determine the optimal investing path and the stock level of international reserves by applying dynamic optimization approach on analyzing the investment behavior so that the total returns are maximized. It constructs an international reserves investing plan (lRIP) model that provides an attention to the actively precautionary motive of holding international reserves under the consideration of opportunity cost in investing action. In addition, sensitivity analyses for the key variables of optimal solution are also provided. Accordingly, this paper represented a dynamic investment philosophy of managing international reserves fur a country’s monetary authority with great reference
An analysis of pricing strategy under growing income inequality: a case of travel product
No full text[[abstract]]From the perspective of the firms, it is important to understand customer's demand and willingness to pay (WTP). The objective of this study is trying to present the pricing strategies on growing income inequality in order to maximize the firm’s profit. A basic premise of this study assume that effective demand function is influenced by consumer’s affordable price. We discuss when the firms set unit selling price of the product is higher(lower) than average value of consumer’s affordable price, whether it will affect profit of the firms, optimal selling price or not. The numerical analysis demonstrates under growing income inequality, when the firms set unit selling price of the product is higher than the average value of consumer’s affordable price, the higher of unit selling price does not bring more beneficial to the firms. When the firms set unit selling price of the product is lower than the average value of consumer’s affordable price, the profit of firms would be gradually convex as the high of unit selling price is
