| dc.description.abstract | In the natural world, water is one of the important factors to maintain life. To let water reach the standard for human drinking, it needs to pass through a series of treatments and construction processes which divided into raw water purge project and water supply project. Raw water purge project is the main function of Water Treatment Plant; after finishing purge, it provides running water to users. For this reason, the water supply pipeline and network need to be set up completely; hence, the whole setting up processes are called “water supply project”. Consequently, the management and maintain are deemed as the most important procedures of water supply project. In order to maintain stable water supply quality and satisfy users’ needs, tap-water supply institutions invite public bidding about all kinds of Water Pipeline Network Projects annually and firmly. So, the most important mission to contract dealer is how to obtain optimized disposition and management toward the outsourcing case in limited manpower, equipment, and source.
In this research, the main study area is how to obtain the biggest bidding outsourcing case for contract dealer in a limited manpower, machines equipment, and source when coping with tap-water pipeline project, and then establish a optimization model which takes MILP Models as carcass to assist dealer about public bidding project. Besides, we adopt all kinds of sensitivity analysis and adjust every source disposition to obtain the best contracted project under the variation trend of the sensitivity of every parameter. So, we formulate every Constraint-Based for existing source and restrictive condition, enter LINGO8.0 tool; finally, you can obtain optimization contracted result for every outsourcing case. To test and verify the applicability of model, we take annual public outsourcing biding in Taipei Water Department as testing example, and the test result is better than the result of rule of thumb. In a nutshell, this study result can be used flexibly to every project field, activate resource disposition plan; finally, assist contract dealer about the important decision of whether he or she should enter a bit or not.
