The article describes a program that reminds users to change their account password in a timely manner, in order to comply with information security requirements and prevent "hacks" and network attacks. The program is developed using a virtual machine (Virtual Box), followed by the installation of the Linux Mint operating system. The software is written in Python programming language, using libraries such as: notify2 (a package for displaying desktop notifications in Linux), schedule (a library for scheduling regular tasks), and other libraries. During the development of Python software for timely password change of the user, key functions were implemented that ensure security and convenience of work: checking the validity of the password, notifying the user.

The article deals with multi-criteria mathematical programming problems aimed at optimizing food production. One of the models of one-parameter programming is associated with solving the problem of combining crop production, animal husbandry and product processing. It is proposed to use the time factor as the main parameter, since some production and economic characteristics can be described by significant trends. The second multi-criteria parametric programming model makes it possible to optimize the production of agricultural products and harvesting of wild plants. in relation to the municipality, which is important for territories with developed agriculture and high potential of food forest resources.

The article is devoted to the review of food production planning models, the analysis of their features. For this purpose, the classification of models was considered, which included models with deterministic and interval parameters, and also took into account the influence of natural and man-made events. The article considers a model for optimizing the functioning of an agro-industrial cluster, presents models for optimizing the production of food products in agro-industrial clusters of the Irkutsk region.
