| The plan diagram for type of horizontal way to draw up the construction plan is Usually adopted in mining industry. Horizontal way diagram apt to be worked out, but it can only express static contact and can't reflect relation of items, which is complicacy and interaction. It can't reflect the engineering's general view and the key place of the engineering. Therefore, it is disadvantage to make reasonable scheduling that the plan diagram is adopted.The Network scheduling regards each relevant work within the Engineering as an organism of the whole. Therefore, it can reflect relation of items, which is inter.dependence and interaction. The Network Scheduling can precede every kind of time calculation, and find out the key work to affecting the work project inside the numerous and complicated scheduling. It is convenient for management personnel to hold the key contradiction, complete the plan on time, and avoid the blindness quickly work period. Painting the network scheduling by making use of the computer, and choosing the optimum scheme from many scheme, this paper attain to cost reduction by reasonable allocation of resources.Develop the programming item that research to manufacture the plan and control process, be used as a system various concrete the each stage of the mission is order of sequence, obtaining the best and economic performance.The work of this paper:1. Through the analysis to reform the item established the mathematics model with the method in network scheduling, establishment time parameter calculator procedure, found out the key circuit, drew the network diagram.2. Making use of "central.limit theorem", this paper proceed to probability estimate and pre.estimate to complete the whole scheduling.3. Making use of " lowest expenses quickly method", this paper propose the methodthat find out the minimal value of the sum of direct cost and indirect cost and corresponding scheduling in network scheduling.4. Optimizing the key route of the renovating engineering and the curve diagram about the human resource, this paper realizes to minimize engineering term and resource (manpower).By the network plan technique, this paper reasonably draws the construction network diagram. Hence, the manager find out the key point in the engineering and the method that shorten the work period, and aim at the weak link to improve scheduling. The study indicates that Application The Network Scheduling to Renovation Project of Lime Handling can shorten engineering term and gain maximum economic benefits, and it is very important to increase management level in mining area. |
