1. Procedure for the preparation of the initial network plan (1) Prepare the process list;
(2) Draw an initial network plan map (initial plan);
(3) Drawing a time-scale network plan map;
(4) Calculate the total duration and make planned adjustments.
2. Optimization of network plan (1) Drawing resource curve After the network plan meeting the requirements of the construction period is determined, the planned consumption curve of the main resources of the construction should be drawn according to the time scale network plan.
(2) Feasibility judgment The main reason is whether the planned site of the resource exceeds the actual possible input. If it is exceeded, it is necessary to make adjustments to shift the construction peaks and reduce the peak of capital consumption; or change the construction method and reduce the amount of resources. At this time, it is necessary to increase or change some organizational logical relationships. While ensuring the requirements of the construction period, meet the planned usage requirements of the resources, and then redraw the time coordinate network plan.
(3) Optimization degree discrimination and submission of construction network plan A feasible plan is not necessarily the optimal plan. The purpose of schedule optimization is to meet the target requirements of the project construction under certain constraints, and the optimization of the plan is a key step to improve economic efficiency. The usual optimization should consider the content of time optimization, cost optimization and resource optimization; if the degree of optimization of the plan is already satisfactory, the construction network that can be used to guide the construction and control the progress is obtained.
Most of the processes have a certain amount of physical engineering, and the working time can be calculated according to the amount of work in the process and according to the amount of resources invested and the quota of the process. If the process is not available, the relevant management cadres, technicians, operators, etc. can be organized to estimate the time required to complete the process based on relevant conditions and experience.
