The purpose of this research is to evaluate the existing distribution system of subsidized fertilizer which is managed by one of the Public Service Obligation State-Owned Companies (PSO-SOC). The evaluation is carried out by comparing the cost of the existing distribution system with the proposed distribution system. Cost optimization of the proposed system makes use of Mixed Integer Linier Programing (MILP). Optimization is performed by restructuring the cluster and distribution warehouse, allowing through trips from plant directly to distributor’s warehouse, and skipping the producer’s warehouse storing. The proposed cluster restructuring can reduce the existing cost to 94% - 98%, while through trips can reduce the total cost to 61% - 72%. In case where through trips is allowed and producer’s warehouse is in operation and functioned as a buffer, the total cost is reduced to 64% - 78% from the existing cost. Based on the optimization result, it is concluded that the existing subsidized fertilizer distribution system could be improved by allowing through trips, while existing producer’s warehouse is still in operation as the buffer warehouse to ensure that the minimum stock is fulfilled. It is noted, however, that this system requires adequate information technology concurrently.展开更多

No matter teachers or students, far from being rational to control their emotion and maximize their gains, are causing more debate than before. The paper,with the method of moral economy analysis, finds the reason that such phenomenon how to break out and what measures to solve the problem. Finally, the paper concludes that the protection system is needed to be structured completely. And the colleges may create a legal responsibility for the teachers to give more priority to subsidized students as it gives to the normal ones.展开更多

There is less attention to poor but formal housing areas, based on the largely untested assumption that the formalization of housing addresses risk. This is at odds with an extensive literature from the housing and developmental sectors that highlights weaknesses in the location and construction of low-income housing, particularly state-subsidized housing. Drawing on research in 10 poor, flood-prone settlements in Cape Town,South Africa, this article explores whether providing housing addresses risk. The results show that flooding remains a challenge in subsidized housing areas and that risk is linked strongly to the buildings themselves. Poorly designed and constructed dwellings perpetuate risk in lowincome areas. While divorced conceptually and practically,disaster risk and housing issues are critically linked, and housing concerns must be factored into discussions on flooding in Cape Town and comparable settings elsewhere.展开更多
