摘要：The DOE methodology is an effective tool for upgrading the level of measurement and assessment. In any design, planning or control problem the designer is faced with many alternatives. He/she is challenged to develop design approaches that can meet both quality and cost criteria. The way experiments are designed greatly affects the effective use of the experimental resources and the easiness with which the measured results can be analyzed. This paper does not present new evidence based on designed experiments. Its objective is solely to show how useful application of multifactor experiments is in a variety of circumstances and decision making scenarios. The paper reviews three published examples where this method was used in different contexts: quality control, flexible manufacturing systems (FMS) and logistics systems. The physical experiment has been carried out to improve the quality of a special type of batteries. The simulation experiment has been carried out to investigate the impact of several flexibility factors in a flexible manufacturing system. The numerical value of a complex analytical expression representing a customer oriented logistics performance measure has been calculated for different values of its parameters, i.e. the given numerical values of the investigated factors. It enabled a methodical examination of all factor effects and especially their interactions, thus shedding light on complex aspects of the logistics decision problem. In these examples, cases from different contexts were presented, enabling to view design of experiments as a powerful ingredient for improving decision making in a variety of circumstances.

摘要：The fuzzy switched PID controller which combines fuzzy PD and conventional PI controller is proposed for ship track-keeping autopilot In this paper. By using rudder angle, the whole voyage is divided into two operating regimes which named transient operating regime and steady operating regime respectively. The fuzzy PD controller is employed in transient operating regime for increasing response, reducing overshoot and shorting transition time. And conventional PI controller is used to improve the stable accuracy in steady operating regime. The global controller is achieved by fuzzy blending of all local controllers. Routh stability criterion is utilized to obtain the stability condition of closed-loop system. The simulation results show the effectiveness of proposed method.

摘要：何谓内控制度内部控制(Internal control System)最早起源于美国,开始是作为根除会计信息的虚假性而采取的相应措施之一,1949年首次定义:'一个企业为保护资产完整、保证会计数据的正确和可靠、提高经营效率、贯彻管理部门既定决策,所制定政策、程序、方法和措施'.后由于这一定义内容过于宽泛,审计人员不便实际操作,便出现了会计控制与管理控制的划分.但这种划分在虽然缓解审计工作的压力,却遭到企业管理人员的反对,认为不利于内控机制的整体设计,难以适应企业的管理需要.故出现'内部控制结构'和'内部控制架构'概念.

摘要：In Rwanda, agricultural industry depends on seasonal rain, and this has been a great challenge to agriculture in Rwanda. The designed sample of Photovoltaic pumping system is for irrigation on a piece of land, with 100 m2 field fed by underground water tank of 8 meters of elevation collected during rainy seasons. The adapted 100 m2 field is based on the fact that Rwanda is a densely populated country, also is adapted to be used especially in horticulture to increase exportation. In this system, a photovoltaic system is used as a power source;a pump is coupled with electric motor to drive it and hosepipe to convey water to the storage tank. A sensor is used to send a signal to the driver section at the same time sending a signal to the microcontroller that controls the driver unit and the corresponding relay, which switches off the motor when the water level reaches the lowest level.

摘要：三十几年来中国企业遵循计划经济体制下的一套生产经营管理模式,使得中国企业至今仍然普遍存在着许多问题,如新产品开发周期长、产品生产周期长、库存在制品储备很高、流动资金占用大、产品交货期长而且不准、生产装备较落后、设备利用率和工时利用率不高、物资采购周期长、生产成本高、利润低、企业缺乏应变能力和市场竞争能力等问题。 随着中国改革开放和社会主义市场经济的发展,企业面临着国内外市场激烈的竞争,旧的产品设计、生产经营管理和生产制造技术已不能适应市场经济的要求,客户对产品的技术要求越来越高,对产品设计、生产周期要求越来越短,客户订单变化迅速,交货期要求很准。为了适应市场经济的要求。

摘要：The Smart Grid has three main characteristics, which are to some degree antagonistic. These characteristics are: provision of good power quality, energy cost reduction and improvement in the reliability of the grid. The need to ensure that they can be accomplished together demands a much richer ICT monitoring and control network than the current system. In this paper we particularly investigate the design and deployment of the ICT system in the urban environment, specifically in a university campus that is embedded in a city, thus it represents the Neighbourhood Area Network (NAN) level of the Smart Grid. In order to design an ICT infrastructure, we have introduced two related architectures: namely communications network architecture and a software architecture. Having access to the characteristics of a real NAN guides us to choose appropriate communication technologies and identify the actual requirements of the system. To implement these architectures at this level we need to gather and process information from environmental sensors (monitoring e.g. temperature, movement of people and vehicles) that can provide useful information about changes in the loading of the NAN, with information from instrumentation of the Power Grid itself. Energy constraints are one of the major limitations of the communication network in the Smart Grid, especially where wireless networking is proposed. Thus we analyse the most energy efficient method of collecting and sending data. The main contribution of this research is that we propose and implement an energy efficient ICT network and describe our software architecture at the NAN level, currently very underdeveloped. We also discuss our experimental results. To our knowledge, no such architectures have yet been implemented for collecting data which can provide the basis of Decision Support Tools (DSTs).
