AN EVALUATION OF PROCESS‐ORIENTED SUPPLY CHAIN MANAGEMENT FRAMEWORKS

Supply chain management (SCM) is implemented by integrating corporate functions using business processes within and across companies. Several process‐oriented frameworks for SCM have been proposed but only two of these provide sufficient detail to enable implementation. We evaluate the Supply‐Chain Operations Reference (SCOR) framework and The Global Supply Chain Forum (GSCF) framework using four criteria and identify their relative strengths and weaknesses.

Optimal allocation of water resources in large river basins: I. Theory

The major purpose of this paper is to present the useful techniques in the optimal allocation of water resources (OAWR) and to demonstrate using water resources applications how these methods can be conveniently employed in practice for systematically studying both simple and complex water resources problems. Formal modelling techniques in multiobjective decision-making provide many benefits to professionals working in water resources and elsewhere. A new Large-system Hierarchical Dynamic Programming (LHDP) method to solve the model can be carried out to ascertain the consequences of meaningful parameter changes upon the optimal or compromise solution.As a case study, the techniques and methods are applied to the OAWR of the Yellow River Basin (YRB) of China. The next paper shares with the reader recent research results on the OAWRYRB.Notation L _i inflows from the trunk stream in the subregioni. - S _i run-off volume of the river sectioni. - Q _i net inflows of intervals in the subregioni. - W _i volumes of water drawn the trunk stream ofi into subdistricti. - H _i volumes of water returning to the trunk stream in the subdistricti. - B _i(W _i) the maximum net benefits (in hundred million yuan) from the annual-water consumption ofW _iin subregioni. - W _ik the annual-water consumption (in hundred million m³) of sectorK in subregioni, k = 1, 2, 3, 4. - B _ik(W _ik the maximum net benefits (in hundred million yuan) from the annual consumptionW _ikof sectork in subregioni. - BS _i(S _i) the maximum net benefits (in hundred million yuan) obtained from the optimal allocation of the run-off volumeS _iof river trunki among different sectors within the months of a year.     

实行工程监理制是工程建设的有效保证

江西地方小水电的建设单位多系临时组建工程指挥部，其成员在专业水平、项目管理、法律知识等方面往往缺乏经验，难以适应小水电建设的需要，业主与承包商之间矛盾不能及时解决，影响了工程进度。实行工程监理制，聘任监理工程师，弥补了建设单位经验不足的欠缺，在多方配合下，保证了工程进度和工程质量。     

三峡枢纽对河口边滩之影响

本文依据现有的１１次长江河口全测图，进行对比分析之后发现，上游来沙数量与河口边滩的冲淤存在良好的关系，从而三峡枢纽兴建后对河口边滩影响进行估计，具有一定的实用价值。     

长洲水利枢纽建坝后水流流态变化的可能性分析

长洲枢纽工程是一个低水头大流量的水力发电工程，河势及流态对枢纽建筑物的布置和调度进行都有较大的影响。本文根据枢纽整体水工模型试验成果，分析枢纽建成前后水流流态变化情况。     

太平溪小流域水土保持蓄水减沙效益初步研究

太平溪小流域地处三峡库乎宜昌县西部，距三峡坝５ｋｍ的长江西陵峡北岸，治理前水土流失严重，大量坡面商沙以沟道推移直接进入三峡库区。     

中国水利的发展方向

黄河下游发生断流的自然因素是降雨偏少、径流量偏枯，决定性因素是黄河流域用水量急剧增加，而直接原因是缺乏有效的管理。黄河上中游的治理造成下游主河槽萎缩，一旦上游发生暴雨，洪水漫流造成灾害。为了保证黄河水资源的可持续利用，必须强调在黄河流域和下游两岸建立节水型的社会并严格保护水源，防止污染。长江中游防洪工作中的重要矛盾是由于人口增长带来土地的过度开发，从而造成围湖和蓄洪的矛盾。今后应根据可持续发展的要求，将水利工作纳入我国人口、资源、环境的巨系统中，修订水利规划，提高用水效率，保护水源和生态环境，完善工程和非工程措施，组织多部门、多学科的协作攻关。
