Методика автоматизированного выбора микроконтроллера при проектировании изделий электронно-вычислительной техники
Purpose. When designing products electronic and computer technology (PECT) developer may need to select the microcontroller (MCU), for example, as the product control system. The problem of MCU choice is very difficult multi-criteria task with significant number of criteria and alternative MCU for comparison. One can obtain satisfactory results choosing intuitively based on own experience [1]-[9] but also can make a mistake. While the formal decision-making support methods steadily provide the most rational choice with conflicting selection criteria and a large number of alternatives.
Methods. It is suggested to divide the MCU selection task on several consecutive phases, gradually converging space selection, and to solve private multicriteria task based on the decision making methods application at each stage: method of rank [11], a group procedure of experts vote, method of analytical hierarchies [10]. Each of these methods has strict algorithm that will automate the entire process of choice MCU under the terms of the draft.
Results. The report considers an example of MCU selection with the decision-making support methods application that systematically reduce MCU list and ultimately leads to the task solution.
Conclusion. The proposed approach allows you to bring the microcontroller selection procedure to sequence of the acceptable decision-making procedures. These procedures, as a rule, do not allow experts make errors and would avoid the expert’s prejudgment in decision-making. The methodology proposed for the MCU selection based on the formal procedures that enables you to automate the selection, taken in account many contradictory factors and the properties of a specific task that will allow getting ultimately more qualitative project decision.
