In order to prepare and optimize multi-dependency construction schedule plan,it is very important to calculate the earliest start times,latest start times,earliest finish times,latest finish times,total floats,free floats and calculated project duration.

A Study on Time Optimization of Alternate Construction Network;

This paper points out that before the construction of the coking oven,should compile the detailed and strict construction plan and construction period,and should implement the norms of the construction of the coking oven strictly,and puts forward some detailed methods for solving the problems frequently occurring in the construction of the coking ovens.

It is not until the beginning of actual construction that the construction planner can realize the validity of his construction operations planning.

This paper describes and analyzes the relationship between FIDIC Contract Conditions and construction program preparation, implementation, management and construction progress control in the course of the construction of Paksey Bridge Project in Bangladesh, and also summarizes the experiences acquired in the implementation of the construction program in question.

Determining the optimal project construction schedule with rsource-based precedence relationships under multiple resource constraints;

With the outstanding functions of spatial modeling and data processing of GIS,also its 3D visualization,we can give a satisfying dynamic model of the construction schedule,which will be a great help for the research and decision-making work of the project.
