According to the current domestic safety assessment, the models, process and motheds of safety assessment and Time Limited Dispatch (TLD) approach were studied hereby.

The current guiding principles for labor contract legislation in our country should be such principles as highlight the protection of laborers,increase the cost of violation of law,stabilize labor relations,restrict labor dispatching,and prevent competitive activities,which is determined by the labor law s particularity and the reality of severely imbalanced labor relations in current China.

Based on the TCFSM,a new model(TCFSM-N) is proposed by re-definition of the time constraints.

Putonghua evaluation test has specific standards of g rading on “time limit” to different items,but in the real practice, there is s ome contradiction between the time limit provided by the “outline” and the act ual time, so a certain confusion easily occurs.

A Brief Discussion on Time Limit of General Habitual Criminals;

The paper analyzes the character of vehicle configure problem of large-quantity cargoes transportation with strict time constraint.

The paper describes the character of the large-quantity transportation problems with strict time constraint,and sets up a single out-point and many in-point transportation model by applying multi-objective programming.

It is the purpose of the present research to explore the characteristic of individual decision making under different time constraints and capital limitations using simulated house-buying task on the computer.
