Formation of situationally dependent systems of requirements for solving the problems of cost planning

An approach to the expert formation of situationally dependent systems of requirements for solving cost planning problems is proposed. The statement and methods for solving linear problem of situational cost planning are presented. Depending on the set of requirements, the problem is solved either by the method of prioritized interval allocation, or by the method of target displacement of solution. Both methods allow finding a cost plan that always meets the mandatory requirements and satisfy the orienting requirements as much as possible. At each step of the plan search in the computational experiment mode, the problem formulation is determined by the system of mandatory and orienting requirements, which is generated by the expert planner on the base of the situation portraits analysis. It is possible to set several indicators of the solution quality. The presentation of input data and the planning result in the form of numerical segments allows to take into account the accuracy of forecasting the amount of the allocated resource and the expected costs. The portraits of situations (target, starting, and achieved) formed with the help of digital twins are presented by a formalized description of the key parameters characterizing the state of the sources of the consumed resource, its consumers, and the planning conditions. The characteristic of the active online cost planning service is given.
