The performance assessment studies are successfully used to describe the irrigation problems and provide remedial measures. In this study, the performance assessment of the twin main canals of the Gezira Scheme were examined and evaluated using a set of performance indicators. The analysis was made using 3 Landsat and 8 Modis data of 2001-2002, and results showed that the seasonal average values of water productivity, relative water supply, overall consumed ratio, depleted fraction and relative evapotranspiration were respectively 0.47, 0.72, 1.41, 0.75 and 0.57 kg·m^-3 for Gezira main canal, whereas the values for Managil main canal were 0.43, 0.54, 1.68, 0.71 and 0.50 kg·m^-3, respectively. The monthly average values of crop water deficit for Gezira and Managil were respectively 71 and 78 mm-month^-1. Considering the spatial variation in some indicators, the irrigation uniformity is deemed as poor according to Molden and Gates （1990）. The analysis also showed that the gap between water demand and supply during winter season was glaringly high （46%）.展开更多

Many companies which developed to a certain stage began to introduce performance management. But a lot of friends in human resources circles always hold a controversy on the effectiveness of performance management. In fact, there are problems on the methods and assessment scales. I personally think that a lot of companies use performance appraisal problem mainly occurs due to the presence misunderstanding the purpose of business resulting from the introduction of performance appraisal. For example： taking the wrong assessment methods, there is no breakdown of the work in advance, nor performed posts and responsibilities ; performance appraisal way to take a negative incentive, the employees complained of performance ; lack of strategic height of human resource management, performance appraisal that can not be linked with the actual situation. The following analysis of several performance evaluation methods and its influence is from the perspective of human resources. Each has its advantages and disadvantages, and also has different emphases. I want to share it with everyone and hope everyone can learn something from it.展开更多

It uses the mathematics statistics knowledge and management knowledge to establish a scientific and operable performance evaluation model for the industrial structure adjustment of the industrial enterprises. Based on the model, it can make a performance evaluation for the internal industrial structure adjustment of the industrial enterprises and also it can evaluate the performance of the industrial structure adjustu^ent of different industries.展开更多

The objectives were to establish benchmarks for both productivity and performance of irrigation schemes along the valley and to inquire whether small schemes function better than large schemes. The performance evaluation study of the systems composed of three general performance indicators, based on three domains-（1） system operation performance; （2） agricultural productivity and economics; （3） financial performance. Each indicator was assessed based on the prescribed descriptors used by the International Water Management Institute （IWMI） and Food and Agriculture Organization （FAO）. Analysis showed an overall system performance efficiency of 59%, 55%, 47% and 36% for Magat River Integrated Irrigation System （MARI1S）, Lucban, Garab and Divisoria Communal Irrigation Systems （CIS）, respectively. In terms of annual productivity performance, Lucban CIS dominates the three other systems with 0.35 kg/m3, which was classified as moderately performing system, while the rest were classified with low productivity index. Financial sustainability of the systems were extremely poor with cost recovery ratio of 0, 0.33, 0.41 and 0.49 for Divisoria, Garab, Lucban and MARIIS, respectively, which were exceptionally below the standard value of at least one. Also, analysis of the indicators revealed that on average, large schemes performed similarly to small-scale schemes, but small schemes were more variable, particularly in input-use efficiency. The benchmarking study will provide strategic information to policy makers of agricultural and irrigation agencies on the existing weaknesses of irrigation systems in the country and determine in a more quantifiable terms levels of potential improvement and intervention targets.展开更多

At the same time, both at home and abroad pay more and more attention to environmental problems caused in harm enterprises enhance their efficiency at the same time, the international and domestic have formulated a series of laws and regulations, the adverse effects of economic activity on the environment caused by the restriction of the enterprise. I studied the development and performance evaluation of green supply chain management, supply from the supply chain management strategy of a successful transition to the green supply chain management decision support for enterprises.展开更多
