Abstract:The transit-operation planning process commonly includes four basic activities: (1) network route design, (2) timetable development, (3) vehicle scheduling, and (4)crew scheduling. Generally speaking vehicle and crew scheduling are critical .The purpose of this work is to address the vehicle and the crew scheduling problem, while taking
into account the interactive association between vehicle and crew. The quasi-assignment model and set-covering model will be applied in solving the problem .We propose new
mathematical formulations and Lagrangian relaxation, and employing twophase hybrid method for dealing with vehicle and crew scheduling problem. Genetic algorithm narrows
down the solution space which consists of potential duties, and then yields some elite schedules. The objective is to minimize the sum of total vehicle and crew costs.

Abstract:This article introduces the methods of moving surface fitting and distance weighted on dealing with digital depth model interpolation, and analyzing their characteristic.
Then the article provides a new method which uses distance weighted to interpolate as a supplement after using moving surface fitting. The method can overcome the weakness
that the constraint condition could not be satisfied in some area when simply using moving surface fitting. The result shows that the new method can get higher accuracy and better
impression, which increases the efficiency greatly.
