Companies today need to keep up with the rapidly changing market conditions to stay competitive. The main issues in this paper are related to a company’s market and its competitors. The prediction of market behavior is helpful for a manufacturing enterprise to build efficient production systems. However, these predictions are usually not reliable. A production system is required to adapt to changing markets, but such requirement entails higher cost. Hence, analyzing different life cycle models of the production system is necessary. In this paper, different life cycle models of the production system are compared to evaluate the distinctive features and the limitations of each model. Furthermore, the difference between product life cycle and production life cycle is summarized, and the effect of product life cycle on production life cycle is explained. Finally, a production system life cycle model, along with key activities to be performed in each stage, is proposed specifically for the manufacturing sector.

How did Archimedes discover the law of buoyancy by experiment?

After Archimedes and Vitruvius era, for more than 2000 years, it has been believed that the displaced water measurement of golden crown is impossible, and at his Eureka moment, Archimedes discovered the law of buoyancy (Proposition 7 of his principles) and proved the theft of a goldsmith by weighing the golden crown in water.
A previous study showed that a small amount of displaced water was able to be measured with enough accuracy by the introduced method. Archimedes measured the weight of displaced water. He did not find the law of buoyancy but rather specific gravity of things at the moment.
After which, Archimedes continued to measure the specific gravity of various solids and fluids. Through these measurements, he reached the discovery of the law of buoyancy directly by experiment. In this paper, the process to the discovery of Archimedes’ principle (Proposition 5) is presented.

结合多年的田间试验研究,对前人诸多研究结果进行了总结和深入分析。结果表明:农田水肥效应大小与试验方法有关,田间试验与模拟试验得到的结论相反。主要原因在于研究中"水"的概念各不相同,从旱棚试验或盆栽试验的结果推断水肥效应与实际情况相距较大。多数情况下,养分亏缺仍是北方旱区作物增产的主要限制因子。灌水的效果取决于土壤底墒、生育期降水、土壤肥力及灌水时期等各种因素。在现有的水资源条件下,提高养分供应水平是北方旱区大部分农田作物增产的主要途径。加强夏闲期降水的蓄积、提高土壤底墒是冬麦区作物高产的重要条件。
