Problems solved by technology

[0005] However, due to the mapping relationship between equipment, stations and targets, and the need to take into account constraints such as preparation time and the number of remaining observations, the core of the problem is complex and the dimensions diverge rapidly. It is difficult to use traditional mathematical models to solve the problem.

Abstract

The invention discloses an optimization constraint determination method for a task dispatching optimization model. The optimization constraint determination method comprises the steps of determining equipment transition constraint, determining remaining observation frequency constraint and determining observation station inlet and outlet constraint. Aiming at the optimal model of a space target observation task dispatching problem for special ground vehicle-mounted measurement equipment, the optimization constraint is determined so as to ensure practicability of an observation scheme.

Description

technical field [0001] The invention relates to the technical field of optimization modeling, in particular to a method for determining optimization constraints of a task scheduling optimization model. Background technique [0002] The present invention relates to a type of ground vehicle measuring equipment (hereinafter referred to as the equipment). The equipment is deployed at a specific ground station, and the equipment can observe the space object in a short time interval when it is over the top. This time interval is called The observation window of the equipment to the space object (the calculation of the observation window involves the working mechanism of the equipment and the motion characteristics and photoelectric characteristics constraints that the space object needs to satisfy. This issue is not the focus of the present invention, and will not be repeated here). The equipment can move along the road with the vehicle, and go back and forth between the garage an...
