Energy Supply and demand, and carbon emission constraints are the problems that must be considered in the process of rapid economic development by national and every province. Under the constraints of energy supply and demand, and carbon emissions, there has practical significance to rational allocate regional energy utilization. With carbon pinch method, this paper research the energy allocation of Tianjin, establish analysis model. Considering the overall and regional energy demand and carbon emission constraints, to determine the usage amount of every kind of fossil energy and clean energy, in order to achieve the best energy structure and optimal balance between energy supply and demand. To provide scientific evidence for local government to make reasonable energy supply and carbon emission constraint index.

Beijing is a typical city of energy resources shortage and there exists the contradiction between energy supply and demand. This paper analyzes the current situation and existing problems of Beijing’s energy utilization, and then forecasts Beijing’s energy supply and demand from 2011 to 2015 based on four kinds of grey forecasting models, finds out that the equilibrium of Beijing’s energy supply and demand is fairly weak with higher external dependence and there is a large room for improving the proportion of quality energy and for developing and utilizing renewable energy. Finally, on the basis of the current situation of Beijing's energy utilization and the development trend in the next few years, some suggestions are proposed.

Due to constant supply and demand cycles of grocery, food, dairy & other everyday products in the shopping complexes, there is no provision available for revision of existing Standard Operating Procedure (SOP) to evaluate its productivity. The productivity of a shopping complex can be determined in terms of sales, utilization of material, machine and manpower, energy utilization and amount of waste utilized. The aim of this paper is to study existing SOP and plant layout in order to suggest modifications through scientific methods which will reflect in optimized productivity. This study implicates material handling processes and equipment as well. The methodology followed belongs to industrial engineering and facility planning tools and techniques. Layout redesigning is performed following the guidelines of various facility planning experts. Work study, time study is performed under observation of teaching professional and the management of the complex. The improvements emphasize on areas where occurrence of problems is more frequent and wastage amounts are very high. Knowing the fact that various factors such as infrastructure, building and capital constraints are inevitable in redesigning the total plant layout, the improvements suggested achieve increased productivity while following all regulations and limitations. This study will not only provide a betterment to the functioning od that complex, but it will provide guidelines for newly undertaken studies and projects.
