Emergency Materials Dispatching And Options On Procurement Strategy

Enter since twenty-first Century, Along with the economic globalization and the coming of information technology times, between the urban and rural social structure changes, various scale emergencies, As of2011March earthquake in Japa、In2011June South China’s sustained rainstorm and flood disasters are frequently attacked us Chennai to environment, Threat, affects our life and life. This kind of unexpected events in addition to a sudden, urgency, as well as a high degree of uncertainty and other characteristics, Also has an impact on the society, such as involving the region area, population much, continuous disasters affecting the characteristics of a long time. So that the emergency material demand points, demand is big, cause of emergency material demand. Therefore, The above characteristics make emergency material dispatch has a high degree of complexity, We should consider not only the single for point to point scheduling, but also consider the supply point to multiple point scheduling; We should consider not only the various stages of dispatching goods of different types, different stages of material dispatching mode should be considered inconsistent. In addition, The procurement of emergency materials occurred some time in the future, but the future of the procurement strategy is uncertain, and the government hopes to reduce this uncertainty supplier. This dissertation first on emergency materials dispatching in the whole process of the qualitative analysis, and then the emergency material dispatch early, late two phases for the quantitative study, finally proposed the use of options contracts for goods and materials procurement mechanism.This dissertation first on emergency materials dispatching in the whole process of research, according to the emergency scheduling, emergency material types, scheduling and scheduling of the different tasks, the emergency materials dispatching is divided into two periods, namely emergency dispatch emergency dispatch and the late prophase. Then established to minimize the total cost and delay time is the shortest for multi-objective deterministic model, and using a variety of methods for solving the, when the total cost as the main consideration, the delay time for the secondary factors, should adopt linear weighting method in the method for solving; Conversely, when the delay time is the main factor, the total cost for the secondary factors, should be adopted gradually method。Secondly, to minimize the total cost was established and the delay time is the shortest for multi-objective model of uncertainty, the uncertainty interval number into real, The conclusion is:the decision on risk preference determines total control costs and delay time. Risk preference is stronger, the operation cost is small, the corresponding delay time is shorter; conversely, the more risk aversion, the total operation cost is bigger, the corresponding delay time is also longer. For the latter part of emergency material dispatch, decomposition established single and a variety of fast moving consumer goods scheduling model, using pseudo polynomial algorithm to calculate, and then an example is given to validate the rationality of the model and the validity of the algorithm. Finally, the option contract mechanism, through the analysis of the government cost and supplier profit changes, The conclusion is:the signing of option contract cases, the government is expected to cost reduction, supplier’s expected profit increase, so there is an option contract mechanism, the supplier’s profit increased government expenditure and cost reduction, i.e. two to achieve a win-win situation.
