Priority Scheduling in the Planning of Multiple-Structure Construction Projects

The paper presents a method of priority scheduling that is useful during the planning of multiple-structure construction projects. This approach is an extension of the concept of interactive scheduling. In priority scheduling, it is the planner that can determine how important each of the technological and organisational constraints are to them. A planner’s preferences can be defined through developing a ranking list that defines which constraints are the most important, and those whose completion can come second. The planner will be able to model the constraints that appear at a construction site more flexibly. The article presents a general linear programming model of the planning of multiple-structure construction projects, as well as various values of each of the parameters that allow us to obtain different planning effects. The proposed model has been implemented in a computer program and its effectiveness has been presented on a calculation example.

Interactive Job Shop Experiments System on Education

In order to simplify teaching work and improve teaching effect for the education of the job shop problem (JSP), an interactive scheduling experiment system (ISES) is introduced. The system realizes interactive function through 3 modules (move interactive, algorithm interactive, evaluation interactive). Group adjustment and Critical path are built to ensure constraints and search the optimal solution in interactive way, Mathematical model and schedule algorithms are built to help teaching. A teaching example is showed at last.
