Algorithmizing the methods of basis matrices in the study of balace intersectoral ecological and economic models

Abstract: Еколого-економічні моделі (типу Леонтьєва-Форда) відіграють особливу роль в розв'язанні принципових проблем перспективного планування з врахуванням природокористування. На їх основі може бути реалізована задача обґрунтування величини затрат на охорону навколишнього середовища з врахуванням соціально-економічного ефекту та розподілу їх у територіально-галузевому розрізі. На основі запропонованої балансової моделі окреслено типові узагальнення («розширення») моделі, які, загалом, збільшують її розмірність, але н… Show more

“…Practical implementation of solution in form (6) is associated with the task on constructing matrices B and , C due to the differentiation of the implicit form of the original nonlinear model, their inversion and multiplication in the construction of expressions of the transformed one and new attributes (7), (8), (10), and (12), (13). Of course, when forming a methodology of transformation and practical realization of results (15), the differentiation of the nonlinear forms of operators or images formed based on them remained the main obstacle.…”

“…Under these conditions, the choice of a model type based on the information about its properties is one of the effective directions in the development of decision support systems [6][7][8][9]. Reducing the time due to the simplicity and analyticity of models, which allows the implementation of rapid computations [6], as well as success-ful introduction of algorithms that operate with long numbers [10], open the way for the implementation of long numbers. Implementation of the latter would make it possible to represent the model's informational image in the form of a single number with an ordered structure [11].…”

“…Along with the classical (Gaussian) scheme of studying SLAE and ZLP, there are variants using the basic matrix method (BMM) whose computational scheme works, tentatively speaking, on the contrary [9][10][11]. Transition is made to the initial model from the auxiliary SLAE with a trivial constraint matrix and known solution by means of equivalent transformations (sequential inclusion of the initial problem constraints).…”

“…If the SLAE as a process model is refined when it undergoes changes, then the problem of analyzing the SLAE properties as a result of changes in the model may be relevant but without re-solving. The problems in this formulation were investigated in [11], in particular, when expanding (or narrowing) the constraints matrix by inclusion (exclusion) of rows or columns. This may be relevant when using SLAE, for example, when solving a boundary value problem using the Galorkin method.…”
