Annotation:

The article considers a mathematical apparatus and software tools that provide the formation of the best strategies for the development of a group of gas fields based on the joint use of simulation modeling, grid methods, discrete and multi-criteria optimization. In modern conditions, the production plan for a group of fields cannot be considered set, i.e. there arises a problem of development strategies optimization for a group of gas fields. Therefore, the task of a production plan development was set and solved, ensuring the maximization of accumulated production for a group of gas fields. The simulation nature of the field group model does not allow setting the objective function and limitations of the optimization problem in an analytical form. Therefore, a continuous optimization of the problem is reduced to a discrete one due to the introduction of a uniform grid and is solved using the modified branch and bound method. In addition to the approximate optimal one, there are found solutions close to it, thus providing solution of the multi-criteria optimization problems for other specified evaluation criteria.
