A Scalable Resource Management Architecture for Wide-Area Industrial Measurement Collaboration on Grids

Research on Web measurement and industrial collaboration in measurement fields in a wide-area and across-organizationally is accepted globally. This paper proposes a novel, scalable management architecture of measurement resources for the resource organization and resource access of the current wide-area collaborative measurement applications in the context of a grid. The complexity of the measurement management on a grid arises from the scale, dynamism, autonomy, heterogeneity, and distribution of the measurement systems and the relative data systems. This paper mainly discusses the interconnection, collaboration, and transparent access of the multi-measurement resources based on the proposed management architecture in the context of complexity. We first discuss the logical architecture used in the measurement fields, and then the resource management system is put at a high premium with layered architecture. Finally, the problems such as resource interconnection, sharing and collaboration are studied in the context of the proposed management environment. The typical applying instance is given to show the advancement of the proposed approach.     

基于资源配（等效性的数据中心能耗优化

针对数据中心服务器的低能效问题,进行了利用资源配置的等效性来优化服务器能效比的研究。研究发现,应用程序的多种资源分配方案具有相同的性能,但表现出较大的能耗差异,这种现象叫做“基于性能等效的资源配置”,简称“等效配置”。基于这种观察,提出了两种优化能效比的算法———SmartRank 算法和 SmartBalance 算法。 Smar-tRank算法使用资源等效替换的方法寻找能耗最低的资源配置,来达到局部最优的能效比;SmartBalance算法通过评估资源需求向量与剩余资源间的关系来均衡资源分配,同时兼顾单个应用的能耗开销,从而达到全局最大能效比。实验表明,通过对这两个算法的优化,可实现平均节省3％的系统能耗,局部最大可以节省12.5％的能耗。

Quality and exposure control in semiconductor manufacturing. Part II: Evaluation

The purpose of this article is to test the performance of a heuristic algorithm that computes a quality control plan. The objective of the tests reported in this paper is twofold: (1) to compare the proposed heuristic algorithm (HA) to an optimal allocation (OA) method; and (2) to analyse the behaviour and limitations of the proposed HA on a scale-1 test with a before/after test. The method employed to evaluate this algorithm is based on comparisons: 1. The first test illustrates the method and its sensitivity to internal parameters. It is based on a simplified case study of a product from the semiconductor industry. The product is made up of 1000, 800 and 1200 wafers incorporating three different technologies. The production duration is 1 week, and three tools were involved in this test. The behaviour of the proposed algorithm is checked throughout the evolution of the model parameters: risk exposure limit (R_L ) and measurement capacity (P). The quality control plan for each tool and product are analysed and compared to those from a one stage allocation process (named C ⁰) that does not take into account risk exposure considerations. A comparison is also performed with OA.

2. The second scale-1 test is based on three scenarios of several months of regular semiconductor production. Data were obtained from 23 etching and 12 photolithographical tools. The outputs provided by the HA are used in the sampling scheduler implemented at this plant. The resulting samples are compared against three indicators.

The results of these comparisons show that, for small instances, OA is more relevant than the HA method. The HA provides realistic limits that are suitable for daily operations. Even though the HA may provide far from optimal results, it demonstrates major MAR improvement. In terms of the maximum inhibit limit, the HA achieves better performances than C ⁰, and they are strongly correlated to R_L and to the control capacity. The article concludes that the proposed algorithm can be used to plan controls and to guide their scheduling. It can also improve the insurance design for several levels of acceptance of risk.     

Use of float consumption rate in resource leveling of construction projects

The management of resources has been claimed to be as important as scheduling methods. Inefficiency in managing resources may bring about severe delays and cost overruns caused by resource shortages in some cases and/or idle resources in others. Therefore, resources should be utilized efficiently to prevent project failures. Resource leveling is one of the approaches that are used for the management of resources. It aims to minimize fluctuations, peaks, and valleys in resource utilization without changing the completion time of a project and the number of resources required. Although the main principle behind traditional resource leveling is achieving an even flow of resources while the original project duration remains unchanged, the literature supports the need to develop an efficient model that discriminates among the activities that are selected for participation in resource leveling. For this purpose, this study has developed a model that considers the float consumption rates of activities in resource leveling. The float consumption rate is the percentage that is set to determine the maximum amount of float which will be consumed to shift the start time of the activity. The proposed model allows a scheduler to assign float consumption rates to each activity that can be used during the resource leveling procedure. When the required information is inputted, the proposed model automatically changes the required daily resources as it shifts the noncritical activities along their available total float times. The proposed model is expected to minimize the likelihood of severe delays and cost overruns. The model is demonstrated by constructing a network and its resource utilization histograms.
